Everything you need to know about NASA's moon mission launching TODAY

NASA’s Artemis I mission launches TODAY: £19 billion Space Launch System rocket will blast off on 42-day journey around the moon – with Snoopy and Shaun the Sheep on board – paving the way for humans to return to the lunar surface by 2025

• Today’s launch of Artemis I mission marks the first step in NASA’s plan to return humans to the moon by 2025
• The £19 billion Space Launch System rocket and uncrewed Orion capsule it carries are preparing for blast-off
• They are set to launch from Kennedy Space Center between 08:33 ET and 10:33 ET (13:33 BST and 15:33 BST)
• The 42-day mission will see Orion capsule fly 60 miles above the moon at its closest before returning to Earth
• If successful, NASA will send Artemis II on a trip around the moon as early as 2024, this time with human crew
• Artemis III would see humans return to moon in 2025, possibly with first woman and/or first person of colour

The dawn of a new era in moon exploration is now just hours away, as NASA prepares to launch the most powerful space rocket ever to leave Earth.

Fifty years have passed since people last walked on the moon — with over half of the world’s population having never witnessed a lunar landing — but today marks the start of humanity’s return for the first time since 1972.

Artemis I is a vital first step if the US space agency is to achieve its goal of landing humans on the lunar surface in three years’ time, possibly including the first woman and first person of colour.

The mission will see an uncrewed Orion spacecraft circle the moon and return to Earth after a 42-day, 1.3 miIlion-mile voyage. 

If all goes to plan, another flight will follow in 2024 – this time with astronauts on board – before human boots once again grace the lunar surface a year later as part of NASA’s ambitious $93 billion (£63 billion) Artemis programme.

People in campervans have been arriving at Cape Canaveral over the weekend, all vying for the best view of the enormous rocket’s lift-off. 

Over 200,000 people are expected to line the beaches and causeways around the Kennedy Space Center to watch the launch, while millions more around the world will tune in on television.

Here MailOnline answers everything you need to know about the forthcoming Artemis I mission, including how you can track the flight live.

Go for launch: NASA is just hours away from launching the most powerful rocket the world has ever seen as part of a 42-day mission that will see an uncrewed Orion spacecraft circle the moon and return to Earth after a 1.3 miIlion-mile voyage

The countdown begins: NASA plans to launch the most powerful rocket the world has ever seen for a mission to the moon

The Apollo 10 lunar module used in 1969 was nicknamed Snoopy after the cartoon dog and a cuddly version of him will also go up in Artemis 1. Soft toys actually serve a useful function on space missions, floating around as a ‘zero gravity indicator’ to show when the spacecraft interior has reached the weightlessness of microgravity

When will the rocket launch?

Lift-off from Cape Canaveral in Florida will take place between 08:33 and 10:33 ET (13:33 and 15:33 BST). 

If for any reason NASA misses this window, the backup is to launch on either September 2 or 5. 

The £19 billion ($22 billion) Space Launch System rocket and Orion capsule that it carries are due to blast into orbit from the Kennedy Space Center’s Pad 39B, just across from the 39A launch complex that fired Apollo 11 to the moon 53 years ago.

THE FLIGHT SCHEDULE

Flight day 1: Launch

Flight day 2-5: Outbound transit

Flight day 6-9: Transit to lunar orbit

Flight day 10-23: Lunar orbit

Flight day 24-34: Exit lunar orbit

Flight day 35-42: Return transit

Flight day 43: Splashdown

How long will it take to get to the moon?

The Apollo 11 mission in 1969, with Neil Armstrong, Buzz Aldrin and Michael Collins on board, took four days, six hours and 45 minutes to get to the moon.

But Artemis I will actually take a bit longer — around a week, but possibly slightly longer.

The plan is for the outbound transit to take place from flight days two to five, before Orion spends the next three days transiting to lunar orbit.

The reason for this is because the spacecraft will be sent toward a distant retrograde orbit around the moon from days 12 to 23, before exiting lunar orbit from days 24 to 34.  

‘Distant’ means the orbit travels far from the moon, while ‘retrograde’ means the orbit will be opposite the moon’s direction of rotation. 

This allows a spacecraft to stay stable for long periods of time using very little fuel, making it an ideal place for Orion to test its capabilities.  

During this time, the capsule will coast roughly 40,000 miles (64,000 kilometres) beyond the moon, breaking Apollo 13’s record for a crewed spacecraft’s distance from Earth.

Its journey home will then last from days 35 to 42, before splashdown occurs on day 43.

ARTEMIS I: MISSION FACTS 

Launch date: August 29, 2022

Mission duration: 42 days, 3 hours, 20 minutes

Total distance travelled: 1.3 miIlion miles

Re-entry speed: 24,500 mph (Mach 32)

Splashdown: October 10, 2022

What does the mission involve?

Named after the twin sister of Apollo in Greek mythology, Artemis signifies the modern incarnation of the US space agency’s Apollo programme, which sent astronauts to the moon for the first time.

At 322ft (98m) — rising 23 storeys above the launch-pad at Cape Canaveral — the rocket is slightly shorter than the Apollo Saturn V that took astronauts to the moon in the 1960s and 1970s.

However, its four RS-25 engines (the same as those used on the Space Shuttle), powered by both solid and liquid fuel, provide greater thrust and a far higher top speed of up to 24,500 mph. (The Saturn V rockets used only liquid fuel because the technology had not yet advanced sufficiently for anything else).

It needs that power to push a large spacecraft out of low-Earth orbit to the moon some 240,000 miles away.

The journey takes a few days and Orion will get as close as 60 miles (100km) from the lunar surface before firing its thrusters to move into orbit up to 40,000 miles (64,000km) away.

Ten shoebox-size secondary payloads, called CubeSats, are hitching a ride to space on Artemis I, while several other investigations are flying inside the Orion spacecraft during the flight test.

Each of the payloads will perform science and technology experiments in deep space, expanding our understanding of lunar science, technology developments, and deep space radiation. 

During re-entry six weeks later, Orion will emerge into the Earth’s atmosphere at 25,000mph before splashing down off the California coast.

Artemis I is designed to show that the SLS rocket and Orion capsule are ready to carry astronauts for Artemis II, and ultimately the Artemis III mission to return humans to the moon.

It would mark the first time people have set foot on the lunar surface since December 1972, when the American astronaut Gene Cernan scratched his young daughter’s initials in the dust next to his footprints before heading home.

The mission: During Artemis I, Orion – which was primarily built by Lockheed Martin – will stay in space ‘longer than any ship for astronauts has done without docking to a space station and return home faster and hotter than ever before,’ NASA said

ARTEMIS I MISSION: SOME OF THE ITEMS ON THE PACKING LIST

• 245 x Silver Snoopy pins
• 1 x Snoopy Zero G Indicator
• 500 x Artemis ‘Medallion’ gold seal stickers for certificates
•  2,775 x Artemis I mission patches
• 1 x Lunar sample button (Apollo 11)
• 567 x American flags
• 1 x Artemis program rubber stamp
• 90 x Girl Scouts Space Science badges
• 1 x Written quote by Dr. Maria Zuber
• 1 x World Space Week lapel pin
• 1 x Sycamore Tree seeds
• 1 x USB drive (images, drawings, poems of space by citizens and students)
• 1 x Dead Sea pebble
• 1 x Wrapped pen nib & Peanuts comic strip
• 1x National Air and Space Museum – Apollo 8 Commemorative Medallion

Will there be astronauts on board?

No — unless you count Shaun the Sheep, Snoopy or the dummy Commander Moonikin as crew. 

This mission will have no humans on board, but as long as everything goes smoothly and the Orion capsule splashes down to Earth on or around October 10, as planned, then the hope is that a four-person crew can make a trip to the moon in 2024.

Instead of humans, a trio of human-sized test dummies will stand in for the crew in the Orion capsule, their bodies swarming with sensors to measure radiation and vibration.

In the commander’s seat will be strapped Commander Moonikin Campos — a tribute to electrical engineer Arturo Campos, who played a key role in getting the troubled Apollo 13 mission safely back to Earth in 1970.

Clad in a new Orion Crew Survival System spacesuit, the mannequin will provide NASA scientists with important data on what humans experience during a trip to the moon.

Two other mannequins named Helga and Zohar will sit in the Orion’s passenger seats, and they reflect the US space agency’s determination that a manned flight to the moon will soon include a woman. 

The dummies have torsos made of materials that mimic a woman’s softer tissue, organs and bones. They will be fitted with some 5,600 sensors and 34 radiation detectors to measure the amount of radiation exposure they encounter during the mission.

One will be wearing a radiation protection vest and the other won’t. 

Scientists say that different organs have different susceptibility to space radiation, and understanding that will be essential to long-term space exploration. 

Women generally have a higher risk of developing cancer, since they have more radiation-sensitive organs such as ovaries and breast tissue.

NASA has also revealed an Official Flight Kit list of items it is sending on Artemis I, including 245 silver Snoopy pins, a Shaun the Sheep mascot, a Dead Sea pebble and 567 American flags.

The Apollo 10 lunar module used in 1969 was nicknamed Snoopy after the cartoon dog, and a cuddly version of him will also go up in Artemis I. Soft toys actually serve a useful function on space missions, floating around as a ‘zero-gravity indicator’ to show when the spacecraft interior has reached the weightlessness of microgravity. 

A small piece of moon rock from the Apollo 11 mission will also join the ride, along with a patch and a bolt from Neil Armstrong’s iconic mission, to help connect the Apollo legacy to the Artemis program. 

Artemis I will even carry a variety of tree and plant seeds, too, as part of tests to study how they are affected by space radiation. Cultivating plants in space is regarded as a critical factor in allowing humans to thrive during longer space missions, providing not only food but oxygen.

Among the items will be 245 silver Snoopy pins (pictured), while a small piece of moon rock from the Apollo 11 mission will also join the ride

How much will it cost?

The Artemis programme as a whole has cost in the region of $93 billion (£63 billion). The costs have ballooned past initial estimates, to the point that NASA Inspector General Paul Martin called them ‘unsustainable’ earlier this year.

However, so far Congress has remained committed to funding Artemis.

When it comes to the launches, each one of the first few Artemis missions is estimated to cost $4.1 billion (£3.4 billion), according to NASA’s Office of the Inspector General.

How can I follow it?

Streaming of the launch will begin on NASA’s website and app at 11:30 BST (06:30 ET), with Hollywood stars Jack Black, Keke Palmer and Chris Evans featuring in the live broadcast. 

An online tool will also allow people to monitor the Orion spacecraft as it travels to the moon and back again during a six-week voyage.

The Artemis Real-time Orbit Website (AROW) will provide imagery, data and all the latest news, while also letting space fans ‘pinpoint where Orion is and track its distance from the Earth, distance from the moon, mission duration, and more.’

NASA added: ‘AROW visualises data collected by sensors on Orion and sent to the Mission Control Center at NASA’s Johnson Space Center in Houston during its flight.

Tracking: The US space agency has revealed a way for the public to track the Orion spacecraft in real time. The Artemis Real-time Orbit Website (AROW) will provide imagery, data and all the latest news

Discussing the new website, its creator Seth Lambert said: ‘This is a really powerful way to engage with the mission and understand the scope of what NASA is trying to accomplish with Artemis I’

NASA also revealed that it will make Orion’s location data freely available for ‘data lovers, artists, and creatives to make their own tracking app, data visualisation, or anything else they envision’

‘It will provide periodic real-time data beginning about one minute after liftoff through separation of the SLS rocket’s Interim Cryogenic Propulsion Stage approximately two hours into flight. 

‘Once Orion is flying on its own, AROW will provide constant real-time information.’

NASA also revealed that it will make Orion’s location data freely available for ‘data lovers, artists, and creatives to make their own tracking app, data visualisation, or anything else they envision.’

It added that while AROW was developed for the upcoming Artemis missions, it may use the same technology to offer visualisations of other space missions in the future.

The AROW website can be viewed here. 

Britain also has an involvement in tracking Artemis I.

The Goonhilly Earth Station in Cornwall will track the uncrewed Orion capsule and provide communications support for the mission.

Goonhilly is the world’s only commercial deep space ground station. In 1969 the site was responsible for distributing live satellite feeds of the Apollo moon landing to people around the world.

Its GHY-6 deep space antenna will receive radio signals from the spacecraft over the six-week duration of its mission.

What happens if it is a success?

If the mission goes to plan, NASA will then send Artemis II on a trip around the moon as early as 2024, this time with a human crew on board.

Four astronauts will enter into a lunar flyby for a maximum of 21 days.

Both Artemis I and II are test flights to demonstrate the technology and abilities of Orion, SLS and the Artemis mission before NASA puts human boots back on the moon in around three years’ time.

This could include the first woman and first person of colour to walk on the lunar surface as part of Artemis III.

Home on the moon: When NASA returns humans to the moon later this decade, its wider vision will be to set up a lunar outpost for people to survive for longer periods. To support that goal, a US company has unveiled its design for a 3D-printed bunker (pictured)

AI SpaceFactory’s outpost would feature Romanesque arches topped with 8ft of lunar soil, along with three separate units that share a communal courtyard

Each unit area is 807 square feet (75 square metres), while the central staging area is 968 square feet (90 square metres)

NASA will land the first woman and first person of color on the moon in 2025 as part of the Artemis mission

Artemis was the twin sister of Apollo and goddess of the moon in Greek mythology. 

NASA has chosen her to personify its path back to the moon, which will see astronauts return to the lunar surface by 2025 –  including the first woman and the next man.

Artemis 1, formerly Exploration Mission-1, is the first in a series of increasingly complex missions that will enable human exploration to the moon and Mars. 

Artemis 1 will be the first integrated flight test of NASA’s deep space exploration system: the Orion spacecraft, Space Launch System (SLS) rocket and the ground systems at Kennedy Space Center in Cape Canaveral, Florida.  

Artemis 1 will be an uncrewed flight that will provide a foundation for human deep space exploration, and demonstrate our commitment and capability to extend human existence to the moon and beyond. 

During this flight, the spacecraft will launch on the most powerful rocket in the world and fly farther than any spacecraft built for humans has ever flown.

It will travel 280,000 miles (450,600 km) from Earth, thousands of miles beyond the moon over the course of about a three-week mission. 

Artemis 1, formerly Exploration Mission-1, is the first in a series of increasingly complex missions that will enable human exploration to the moon and Mars. This graphic explains the various stages of the mission

Orion will stay in space longer than any ship for astronauts has done without docking to a space station and return home faster and hotter than ever before. 

With this first exploration mission, NASA is leading the next steps of human exploration into deep space where astronauts will build and begin testing the systems near the moon needed for lunar surface missions and exploration to other destinations farther from Earth, including Mars. 

The will take crew on a different trajectory and test Orion’s critical systems with humans aboard. 

Together, Orion, SLS and the ground systems at Kennedy will be able to meet the most challenging crew and cargo mission needs in deep space.

Eventually NASA seeks to establish a sustainable human presence on the moon by 2028 as a result of the Artemis mission.

The space agency hopes this colony will uncover new scientific discoveries, demonstrate new technological advancements and lay the foundation for private companies to build a lunar economy. 

What if it fails?

It hasn’t been a smooth development process for the SLS rocket. 

The booster was already three years behind schedule and almost $3 billion (£2.5 billion) over budget when it suffered a series of issues during testing last year.

Its engines were meant to run for four minutes but ended up being cut off after a little over a minute.

The question now is, with a much-maligned programme that is behind schedule and has cost lot more than planned, how much room for error is there?

Not much, according to many experts, as a failing project that is over budget is much harder to achieve political and public backing for.

‘This has to work,’ said Casey Dreier, of the Planetary Society.

However, John Logsdon, founder of the Space Policy Institute at George Washington University, said ‘lots of things can go wrong, some things are likely to go wrong’.

He added: ‘The question is are they catastrophic failures, or failures that can be addressed and fixed, and we won’t know that until we fly the mission.

‘NASA recognises that the world is watching.’ 

What does it mean for the future of space travel and lunar exploration?

Beyond landing the first woman and first person of colour on the moon, NASA hopes to build a base camp and carry out annual missions to the lunar surface. Ultimately the US space agency hopes it can be used as a stepping stone for long-duration voyages, including human missions to Mars.

Additional pieces of Artemis infrastructure are also well under way. 

In a partnership with the Canadian and Japanese space agencies, NASA is building the Gateway space station to orbit the moon. 

This craft is meant to provide a staging ground for future sorties to the lunar surface. 

Parts of the Gateway are already being built, and its first two modules could be launched as early as 2024. 

The Artemis IV mission — which will launch no sooner than 2026 — is slated to finish the Gateway’s assembly in lunar orbit. 

When was the last time humans walked on the moon? 

In December 1972, Eugene Cernan had the distinction of being the ‘last man on the moon’ after he became the final astronaut to re-enter the Apollo Lunar Module. No human being has been back since.

Before leaving the lunar surface, Captain Cernan delivered a message to Earth while standing next to the American flag, which still stands in the lunar soil.

He said: ‘I think probably one of the most significant things we can think about when we think about Apollo is that it has opened for us — “for us” being the world — a challenge of the future.

‘The door is now cracked, but the promise of the future lies in the young people, not just in America, but the young people all over the world learning to live and learning to work together.

‘As I take man’s last step from the surface, back home for some time to come — but we believe not too long into the future — I’d like to just (say) what I believe history will record.

‘That America’s challenge of today has forged man’s destiny of tomorrow. And, as we leave the moon at Taurus-Littrow, we leave as we came and, God willing, as we shall return, with peace and hope for all mankind. Godspeed the crew of Apollo 17.’

Captain Cernan, a retired US Navy captain, was the second American to have walked in space and the commander of Apollo 17. 

He also held the unofficial lunar land speed record after recording a maximum speed of 11.2 mph during an Apollo 17 EVA.

On their way to the moon, the Apollo 17 crew took one of the most iconic photographs in space-programme history, the image of the Earth dubbed ‘The Blue Marble.’

The Apollo 17 mission saw Cernan and his fellow astronauts land the Challenger on the moon, where they would spend the next three days exploring and taking samples.

Captain Cernan logged 566 hours and 15 minutes in space — of which more than 73 hours were spent on the surface of the moon. He passed away aged 82 in 2017

It set new records for longest manned lunar landing flight, longest time in lunar orbit, longest time in lunar extravehicular activities and biggest lunar sample return.

During that time, Captain Cernan logged 566 hours and 15 minutes in space — of which more than 73 hours were spent on the surface of the moon. 

While he and lunar module pilot Harrison H. (Jack) Schmitt conducted activities on the lunar surface, command module pilot Ronald Evans remained in orbit.

Captain Cernan passed away aged 82 in 2017.

Who could be the first woman on the moon?

NASA is planning to land the first woman on the moon as part of the Artemis programme and has whittled down the list to just nine candidates.

They are Kayla Barron, Christina Koch, Nicole Mann, Anne McClain, Jessica Meir, Jasmin Moghbeli, Kate Rubins, Jessica Watkins and Stephanie Wilson.

Kayla Barron

Contender: Kayla Barron, who has been an astronaut for five years, is the second youngest to be chosen for NASA’s Artemis programme

Kayla Barron has been a NASA astronaut for five years but is the second youngest to be chosen for the Artemis moon-landing program in 2025.

She has UK links, after earning a master’s degree in Nuclear Engineering from the University of Cambridge.

The 34-year-old was also part of the first group of women to become submarine warfare officers. 

Barron served as member of the SpaceX Crew-3 mission to the International Space Station, which launched on November 10, 2021. 

She worked as a flight engineer during the expedition and completed a six-and-a-half hour spacewalk to replace a communications antenna that had malfunctioned.

Barron returned in March this year after spending almost 177 days in orbit.

Of her future aspirations, she has previously said: ‘When I stand outside at night and look up at the moon, every once in a while I’ll try to imagine myself standing on the moon and looking back at Earth.

‘It’s just such a hard thing to wrap your head around.’

Barron’s father Scott Sax works as a project engineer for the US Department of Energy but has always harboured a dream of working for NASA. 

His daughter went on to realise this aspiration when she was selected to join the US space agency in 2017 at the age of 29.

Christina Koch

Breaking down barriers: Christina Koch is the record holder for the longest single spaceflight by a woman, at 328 days

KEY FACTS

Astronaut Selection Year: 2013

Previous missions: Expedition 61, Expedition 59, Soyuz MS-13, Expedition 60, Soyuz MS-12 

Colleges and Degrees: Bachelor of Science in Electrical Engineering, a Bachelor of Science in Physics, and a Master of Science in Electrical Engineering from North Carolina State University in Raleigh, North Carolina.

Christina Koch is the record holder for the longest single spaceflight by a woman, having spent 328 days in orbit during her trip to the International Space Station (ISS) between 2019 and 2020.

That surpassed the previous record of 288 days held by Peggy Whitson. 

Just a few months prior, Koch and another female astronaut, Jessica Meir, completed the first all-woman spacewalk. 

In total, she is a veteran of six spacewalks totalling 42 hours and 15 minutes, including the first three all-women spacewalks. 

Following her record-breaking ISS mission, Koch was included in Time’s Most Influential People of 2020.

From a young age, she wanted to be an astronaut, and joined her middle school’s ‘Rocket Club’.

The 43-year-old has previously worked in Antarctica at the Amundsen-Scott South Pole Station and Palmer Station, while she later contributed to instruments on the Juno spacecraft and Van Allen probes.

After being selected for the Artemis programme, she said: ‘To me, what [Artemis] really represents is that NASA is committed to answering humanity’s call to explore by all and for all. 

‘We’re an example of how you’re most successful when you take contributions from every single part of the world, and the planet and humanity.’

She also tweeted about her training back in January, writing: ‘Met our aircraft today. 

‘Path finding a new helicopter training program for the @nasaartemis generation. Taking the lessons from #Apollo in vertical flight and landings and bringing them back to the Moon!’

Nicole Mann

Striving for the moon: Almost a decade ago Nicole Mann was one of eight candidates selected from more than 6,300 applicants to train as an astronaut for NASA

KEY FACTS

Astronaut Selection Year: 2013

Previous missions: Boeing Crewed Flight Test, SpaceX Crew-5 

Military Experience: U.S. Marine Corps

Colleges and Degrees: Bachelor of Science in Mechanical Engineering from the United States Naval Academy and a Master of Science in Mechanical Engineering with a specialty in Fluid Mechanics from Stanford University.

Hometown: Petaluma, California

Age: 45

Time spent in space: 0 days

Nicole Mann is a Colonel in the Marine Corps and a former test pilot who flew 47 combat missions in Iraq and Afghanistan. 

In total, she has logged upwards of 2,500 hours of flight time in 25 different aircraft.

Mann’s friends and fellow crew call her ‘Duke’, a nickname she has said was actually her call sign in the Marines. 

Almost a decade ago she was one of eight candidates selected from more than 6,300 applicants to train as an astronaut for NASA. 

After completing her astronaut training in 2015, the mother-of-one was supposed to be among the first human passengers on Boeing’s Starliner spacecraft during its first crewed flights in the coming years.

But in 2021 she was reassigned to the SpaceX Crew-5 mission, which is due to launch to the International Space Station next month with Mann as the mission commander.

In an interview with National Geographic, Mann mentioned her eight-year-old son, saying: ‘We always sit outside, and we love to look at the stars and look at the moon — but now I think both of us look at it with a little different light in our eyes, and a little different twinkle. 

‘Hopefully someday, he’ll be able to watch Mom fly by and walk on the moon.’

Mann’s training has included flying T-38s — the same aircraft the Apollo astronauts used to travel between air bases more than 50 years ago. 

She has said of potentially being First Woman: ‘Yes, you want to be the first person to walk on the moon, you want to fulfil that role, but really it’s not about you.

‘It’s about the bigger mission, so you’re just excited to support in whatever role you can.’

Anne McClain

Military background: Anne McClain is a former army helicopter pilot and Iraq veteran who went by the call sign ‘Annimal’

KEY FACTS

Astronaut Selection Year: 2013

Previous missions: Expedition 59, Expedition 58, Soyuz MS-11, Expedition 57 

Military Experience: U.S. Army

Colleges and Degrees Bachelor of Science in Mechanical/Aeronautical Engineering from the U.S. Military Academy at West Point and a Master of Science degree in Aerospace Engineering from the University of Bath in Bath, England.

Hobbies: Enjoys weightlifting, rugby, golf, biking, CrossFit, and running.

Hometown: Spokane, Washington

Age: 43 

Time spent in space: 203 days, 15 hours and 16 minutes

Anne McClain is a former army helicopter pilot and Iraq veteran who went by the call sign ‘Annimal’.  

It dates back to her rugby days at university in the UK, while she also uses the name in her Twitter handle, ‘AstroAnnimal’.

The 43-year-old played rugby in the English Women’s Premiership and credits the sport with giving her the ‘grit, toughness and mental focus’ to succeed as an astronaut.  

She is a big fan of Top Gun and has revealed that she watched it so much one summer that her brother broke the tape to get her to stop watching the film.

McClain said she was devastated, but it was that incident that inspired her to become a military pilot.

She was initially slated to carry out the first all-woman spacewalk alongside Christina Koch during Women’s History Month in March 2019, but spacesuit sizing issues resulted in the EVA being reassigned to Nick Hague and Koch. 

The latter would go on to make the first all-female spacewalk alongside Jessica Meir. 

In 2019, McClain was investigated and subsequently cleared by NASA over what was characterised as the first alleged space crime.

She was accused by her estranged spouse of improperly accessing bank records while on a six-month mission aboard the ISS.

After being cleared of any wrongdoing, McClain’s former partner Summer Worden was charged with making false statements to federal authorities.

McClain has spent a total of 204 days in space and was lead spacewalker on two spacewalks, totalling 13 hours and 8 minutes on her mission on the ISS.

‘We were asked to draw a picture of what we want to be when we grow up, and I distinctly remember drawing an astronaut in a spacesuit standing on the surface of the moon next to the American flag,’ said Meir, 45, who Time magazine named one of the most influential people of 2020. 

At the age of 13, she also attended a youth space camp at Purdue University — Neil Armstrong’s alma mater.

She was eventually chosen to join NASA in 2013, before carrying out physiological training, survival training, flight classes and a wide range of technical training at space centres around the world. 

Meir served as flight engineer on the International Space Station for expeditions 61 and 62, after launching to space aboard Soyuz MS-15 on September 25, 2019. Her arrival marked an unusual period on the station because there were nine people aboard. 

The ISS is designed to support a crew of six at one time.

She also completed the first all-female spacewalk alongside Christina Koch in October 2019.

Apart from English and Russian, which are required for astronaut training, Meir also speaks Swedish because her mother is from Sweden and father from Israel.

Astronauts are allowed to bring a number of personal items to the International Space Station, so Meir chose an Israeli flag and a pair of novelty socks with Stars of David as part of her allocation. 

She played flute, piccolo, and saxophone when she was younger and enjoys reading classical literature.

Prior to becoming an astronaut, her career as a scientist focused on the physiology of animals in extreme environments.

She also took part in Smithsonian Institution diving expeditions to the Antarctic and Belize, and has been very active with scientific outreach efforts. 

When asked how it would feel to be the first woman to walk on the moon, Meir said: ‘I would be incredibly excited and fortunate to be that first woman on the moon. 

‘I’d have to think long and hard about what my first words would be upon stepping on the lunar surface. 

‘I’ve been asked about this many times, but I think the most important part to remember is that it would certainly not be about my personal achievement. It’s about representing everyone here at NASA, and, far beyond that, all of the people that brought us to where we are today. 

‘I would proudly be serving as a representative for all of humanity in that big step forward in exploration.’

Jasmin Moghbeli’s Twitter bio reads ‘Mommy. Marine Attack Helicopter Pilot. Test Pilot. NASA Astronaut. Excited to share my journey!’

She is mother to twin girls and earlier this year tweeted: ‘Incredibly grateful to be a mom to these two, who fill my heart and never fail to make me smile!’ 

In March, the 39-year-old was selected to be the commander for NASA’s upcoming SpaceX Crew-7 mission to the International Space Station.

The mission is expected to launch no earlier than 2023 on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. 

lt will be the first spaceflight for Moghbeli, who became a NASA astronaut in 2017.

She was born in what was then West Germany to an Iranian family, before her parents emigrated to the US.

Moghbeli later earned a bachelor’s degree in aerospace engineering with information technology at the Massachusetts Institute of Technology, where she played volleyball and basketball.

She also loves to go skateboarding with her husband, as well as paddle boarding, dancing and flying kites. 

As a Marine Corps test pilot, she has flown more than 150 missions and accrued 2,000 hours of flight time in more than 25 different aircraft. 

She also graduated with honours from the U.S. Naval Test Pilot School in Patuxent River, Maryland. 

At the time of her selection as an astronaut, Moghbeli was testing H-1 helicopters. 

Her dream of becoming an astronaut can be traced all the way back to sixth grade, when she did a book report on the first woman in space, Russian cosmonaut Valentina Tereshkova.

She has said she remembers her mother helping to make a spacesuit to wear into class for the report.

Kate Rubins became the 60th woman to fly in space when she launched on a Russian Soyuz spacecraft to the International Space Station on July 7, 2016. 

During her mission she became the first person to sequence DNA in space.

Across her two flights, she has spent a total of 300 days in space, the fourth longest stint by a US female astronaut. 

A microbiologist as well as a NASA astronaut, Rubins also holds a Ph.D. in cancer biology and calls herself a ‘former virus hunter’ on Twitter. 

When she was younger she didn’t dream of becoming an astronaut, but rather was more focused on studying and eradicating viruses.

That’s exactly what she did after receiving degrees from the University of California-San Diego and Stanford. 

Rubins later researched therapies for Ebola and Lassa viruses while helping to develop a smallpox infection model.

During her most recent trip to the International Space Station she worked on a heart experiment to study how changes in gravity affect cardiovascular cells at the cellular and tissue levels. 

Her results could provide new understanding of heart problems on Earth, help identify new treatments, and support development of screening measure to predict cardiovascular risk prior to spaceflight.

Last year, Rubins was sworn into the Army Reserve as a Major. 

When previously asked about the significance of becoming the first woman to walk on the moon, Rubins said: ‘I think it’s not so important whether it is a step for man or woman. This will be a step for humankind.’

The Colorado native earned a Bachelor of Science in Geological and Environmental Sciences from Stanford University, and a Doctorate in Geology from the University of California, Los Angeles (UCLA).

She has been documenting her journey aboard the ISS on Twitter.

In June Watkins wrote: ‘As beautiful as the Earth is, I can’t seem to take my eyes off of the moon.

‘Every moonset on @Space_Station brings us one step closer to earthrise on the moon as we conduct scientific research and develop new technologies that will help pave the way to the lunar surface.’

She also shared pictures of herself doing ‘space plumbing’ to fix a toilet on the ISS, and in a separate tweet added: ‘One of my favorite parts about being in orbit is getting to observe geologic features on Earth from a planetary perspective.

‘A great example is the Grand Canyon – truly grand both from afar and up close, but Valles Marineris on Mars is 4x as long, 4.5x as deep, and 20x as wide!’

Stephanie Wilson became the second Black woman in space and is a veteran of three Space Shuttle missions to the International Space Station — in 2006, 2007 and 2010.

She is NASA’s most senior, most flown-in-space African American female astronaut, having logged more than 42 days in orbit.

If selected as the First Woman, she would also take the title of the oldest person to have walked on the moon, eclipsing Alan Shepard’s record of 47 years and 80 days back in 1971.

She has been an astronaut longer than anyone else on the 18-strong Artemis team and has flown more times than all but one of them. 

Wilson earned a bachelor’s degree in engineering science at Harvard University and a master’s degree in aerospace engineering at the University of Texas.

She was the lead CAPCOM during the Columbia disaster in 2003 and again for the first all-woman spacewalk in 2019.

In 2009, 2013, and 2017, she served on the Astronaut Selection Board and currently acts as Astronaut Office Mission Support Crew Branch Chief. 

With regard to her lunar prospects, Wilson told Space.com: ‘I am of course excited to be included among the group and look forward to whoever the first woman is and the women who follow as part of the Artemis program to continue our studies of the moon, continue to descend down to the surface in a lander and hopefully to build a lunar base there on the moon and continue our journey from the Gateway orbiting laboratory.’

How does the SLS rocket differ from Neil Armstrong’s Saturn V?

Standing taller than the Statue of Liberty and having cost an eye-watering $23 billion (£19 billion) to build, NASA’s brand new mega moon rocket is now just weeks away from its maiden launch.

The enormous Space Launch System (SLS) is scheduled to blast into space on August 29 as part of a six-week mission that will see it carry an uncrewed Orion spacecraft to lunar orbit and back. 

It will be the first of three planned trips to the moon that will culminate in returning humans to the lunar surface for the first time since the 1970s.

Known as the Artemis program, NASA wants to land the first woman and the first person of colour on the moon by 2025 — and the SLS will be the vehicle to take them there.

Head to head: Standing higher than the Statue of Liberty and costing $23 billion (£19 billion) to build, NASA’s brand new mega moon rocket (pictured left) is now just weeks away from its maiden launch. Here is how the SLS compares to the iconic Saturn V rocket (right), which blasted Neil Armstrong, Buzz Aldrin and Michael Collins to the moon in July 1969

HOW DOES THE SLS ROCKET COMPARE TO SATURN V?

SLS rocket

First launch: August 2022?

Program: Artemis 

Height: 322ft (98m)

Weight: 5.5 million pounds (2.5 million kg)

Thrust: 8.8 million pounds (39.1 Meganewtons)

Max payload to low-Earth orbit: 210,000 pounds (95 tonnes)

Max payload to lunar orbit: 59,500 pounds (27 tonnes) – the equivalent of 11 large SUVs

Solid fuel: Polybutadiene acrylonitrile

Liquid fuel: Oxygen and hydrogen

Top speed: 24,500mph (39,500km/h)

Engines: Four RS-25 engines sit at the base of the core stage – the same ones used on the space shuttle

Crew module: Orion (capable of carrying four astronauts)

Cost to build: $23 billion (£19 billion)

Price per launch: $4.1 billion (£3.3 billion)

Total launches: 0 

Saturn V

First launch: November 1967

Program: Apollo 

Height: 363ft (110m)

Weight: 6.2 million pounds (2.8 million kg)

Thrust: 7.6 million pounds (34.5 Meganewtons)

Max payload to low-Earth orbit: 260,000 pounds (118 tonnes)

Max payload to lunar orbit: 90,000 pounds (41 tonnes) – the equivalent of 17 large SUVs

Solid fuel: N/A

Liquid fuel: Kerosene, oxygen and hydrogen

Top speed: 17,400mph (28,000km/h)

Engines: Five F-1 rocket engines, constructed in 1963 by the Rocketdyne Division of Rockwell International

Crew module: Three-man command module (Columbia)

Cost to build: $6.417 billion in 1969 ($51.8 billion in 2022)

Price per launch: $185 million in 1969 ($1.49 billion in 2022)

Total launches: 13 

Weighing 5.5 million pounds (2.5 million kg) and capable of generating almost 40 Meganewtons of thrust, the rocket is the modern equivalent of the Saturn V, the huge launcher built during the Apollo era which powered Neil Armstrong, Buzz Aldrin and Michael Collins to the moon in 1969.

The two rockets may have been built more than half a century apart, but despite huge technological advances, the SLS doesn’t necessarily eclipse the Saturn V on every metric.

Here, MailOnline compares how the vehicles stack up against each other, from their height, weight and top speed, to cost per launch, fuel type and payload capabilities.

The first version of the SLS will be called Block 1, before undergoing a series of upgrades over the next few years so that it can launch heavier payloads to destinations beyond low-Earth orbit.

NASA hopes its mega rocket won’t just take astronauts to the moon, but will eventually be capable of blasting humans to Mars and beyond.

Height, weight and thrust 

The Block 1 SLS will stand at 322ft (98m) and tower 23 storeys above the launch pad — meaning it is not quite as tall as the Saturn V’s colossal 363ft (110m) stature.

It also weighs less – at 5.5 million pounds (2.5 million kg) compared to 6.2 million pounds (2.8 million kg) – but the 2022 rocket is by no means a little brother to its iconic predecessor. 

Development: The first version of the SLS will be called Block 1, before undergoing a series of upgrades over the next few years so that it can launch heavier payloads to destinations beyond low-Earth orbit

Remarkably, the Saturn V (pictured) went from paper design to flight in just six years — having entered formal development in January 1961 and launching for the first time in November 1967

‘It is truly an immense rocket. It is just jaw-droppingly big,’ said John Shannon, vice president and program manager for the SLS at Boeing, the rocket’s prime contractor.

Not only is it big, but it dwarfs Saturn V when it comes to the thrust it is capable of generating.

The SLS’s four RS-25 engines, which were also used on the space shuttle, can produce 8.8 million pounds (39.1 Meganewtons) of thrust — 15 per cent more than the Saturn V’s 7.6 million pounds (34.5 Meganewtons).

On thrust alone, the SLS will be the most powerful rocket ever built when it finally launches.

It also has a top speed of 24,500mph (39,500km/h), compared to 17,400mph (28,000km/h) for the Saturn V.

Cost and length of time to build

It may be an astonishing amount of money, but the $23 billion (£19 billion) that went into developing and building the SLS actually equates to about half of what was spent on the Saturn V, when inflation is taken into account.

The latter cost around $6.4 billion (£5.2 billion) in the 1960s, which in today’s money works out at about $51.8 billion (£42.3 billion).

Remarkably, however, the Saturn V went from paper design to flight in just six years — having entered formal development in January 1961 and launching for the first time in November 1967. 

The brainchild of German-born engineer Wernher von Braun, it successfully flew 13 times before being retired.

The SLS design was unveiled in 2011 but entered the formal development stage eight years ago. So despite the numerous technological improvements over the past five-and-a-half decades, it has still taken longer than it took von Braun in the Sixties.

Make-up: Its core stage stores 730,000 gallons of super-cooled liquid hydrogen and liquid oxygen that fuel the RS-25 engines

Power: The SLS’s shuttle-derived solid rocket boosters (pictured) contain the propellant polybutadiene acrylonitrile and provide more than 75 per cent of the vehicles thrust during the first two minutes of flight

Many of the delays have been caused by issues with the SLS itself, while the Artemis program has also been dogged by problems with the development of spacesuits and the human lander systems that will take crew to the lunar surface. 

Legal issues have held it up, too. Last year Jeff Bezos’ Blue Origin unsuccessfully sued NASA over a decision to award the human lander system contract solely to SpaceX. 

It may have taken longer to get to this point but NASA is now building the SLS rockets needed for several missions. 

To reduce cost and development time, the US space agency is also upgrading proven hardware from the space shuttle and other exploration programs, while making use of cutting-edge tooling and manufacturing technology. 

Some parts of the rocket are new and others have been upgraded with modern features that meet the needs of deep space missions.

Although the Saturn V may have cost more to develop and build, it is not as pricey to launch. 

It cost $185 million per blast-off in 1969 – the equivalent of $1.49 billion (£1.2 billion) in today’s money – while the SLS is estimated to be closer to $4.1 billion (£3.4 billion).

How the SLS works compared to Saturn V

NASA’s new mega rocket will be powered by a core stage that is flanked by two solid rocket boosters, and an upper stage called the Interim Cryogenic Propulsion Stage.

How it looks: NASA’s SLS rocket will be powered by a core stage that is flanked by two solid rocket boosters, and an upper stage called the Interim Cryogenic Propulsion Stage

This is a different setup to the Saturn V’s three rocket stages. That vehicle didn’t use boosters in any form because it was sized so as to not need them.

Solid propellant technology was also still not very good in the 60s, so the Saturn V was powered by a mixture of kerosene, liquid oxygen and liquid hydrogen.

The SLS’s shuttle-derived solid rocket boosters contain the propellant polybutadiene acrylonitrile and provide more than 75 per cent of the vehicles thrust during the first two minutes of flight. 

Its core stage, meanwhile, stores 730,000 gallons of super-cooled liquid hydrogen and liquid oxygen that fuel the RS-25 engines.

What about the crew capsules?

As previously mentioned, the Saturn V was split into three stages. The first used five F-1 engines to lift the massive rocket off the ground, before it was jettisoned to allow for burns by the second and third stages. 

Ultimately these also separated from the Apollo spacecraft, leaving just the command module, service module and the lunar lander — complete with an ascent and descent stage.

In the case of Apollo 11, the command module was known as Columbia. This is what transported Collins, Aldrin and Armstrong to lunar orbit, before the latter pair made their journey down to the surface.

SLS’s next-generation crew vehicle, known as Orion, will actually cater for four astronauts rather than the three on top of Saturn V. 

While the end of this month will be the first launch of the SLS, it will be the second for the Orion capsule, which was involved in a test flight in December 2014 when it went to space on a ULA Delta IV Heavy.

When it launches, Orion won’t have any crew on board but will instead carry dummies to the moon and back.

These are designed to replicate human weight, and give scientists and engineers and insight into flight performance, without putting humans at risk. 

Unlike the Apollo capsule’s single flight computer, Orion is equipped with two redundant flight computers that operate simultaneously. Each one is also equipped with two redundant computers. 

Orion’s computers also hold significantly more memory and operate at much faster speeds than an Apollo-era computer. 

In fact, NASA says they operate 20,000 times faster and the memory capacity is 128,000 times greater.

Splashdown: In the case of Apollo 11, the command module was known as Columbia (pictured). This is what transported Collins, Aldrin and Armstrong to lunar orbit, before the latter pair made their journey down to the surface

Home sweet home: SLS’s next-generation crew vehicle, known as Orion (pictured in an artist’s impression), will actually cater for four astronauts rather than the three on top of Saturn V.

And the rest of the payload?

In terms of a maximum payload to low-Earth orbit, the SLS is slated to be able to carry some 210,000 pounds, the equivalent of 95 metric tonnes.

As a comparison, the Saturn V could transport 260,000 pounds (118 tonnes). 

The former’s max payload to lunar orbit, meanwhile, is 59,500 pounds (27 tonnes) – the equivalent of 11 large SUVs – while the latter’s was 90,000 pounds (41 tonnes).

Although the Saturn V technically wins here on paper, the SLS payload capability is expected to grow with newer iterations of the design.

Liftoff: In terms of a maximum payload to low-Earth orbit, the SLS is slated to be able to carry some 210,000 pounds, the equivalent of 95 metric tonnes. As a comparison, the Saturn V (pictured) could transport 260,000 pounds (118 tonnes)

Dry-run: Apollo 7 was the first test flight in the program to be launched to space. It was followed by three more flights – including 9 (pictured) and 10, the latter of which orbited the moon – before the famous lunar landing in 1969

What is more crucial, however, is not necessarily the maximum payload a vehicle can transport but the cost that it takes to do so. 

This is often seen as one of the most prohibitive things about space travel, particularly when it comes to longer duration human missions to places like Mars. More on that later.

How do the test missions compare to the main event?

During Artemis I, Orion – which was primarily built by Lockheed Martin – will stay in space ‘longer than any ship for astronauts has done without docking to a space station and return home faster and hotter than ever before,’ NASA has said. 

The mission is designed to show that SLS and Orion are ready to carry astronauts.

If Artemis I is a success, NASA will then send Artemis II on a trip around the moon as early as 2024, this time with a human crew on board.

The Artemis II mission plans to send four astronauts into a lunar flyby for a maximum of 21 days.

Both missions are test flights to demonstrate the technology and abilities of Orion, SLS and the Artemis mission before NASA puts human boots back on the moon.

With the Saturn V – before any Apollo mission flew – NASA dealt with a major tragedy in January 1967. 

As astronauts Gus Grissom, Ed White and Roger Chaffee were carrying out a simulation on the launch pad in Florida, a flash fire broke out in their capsule and killed all three.

The disaster caused NASA to re-examine all aspects of the program and rework many of the spacecraft’s systems, meaning it wasn’t until October 1968 that the first Apollo mission got to space.

Apollo 7 was followed by three more flights that operated in a similar way to the plan for Artemis, with 10 being the second to orbit the moon and acting as a dry-run for the famous lunar landing that took place two months later.

Side by side: This shows how the SLS compares to Saturn V, SpaceX’s Starship and Falcon Heavy, and the space shuttle

STARSHIP AND SUPER HEAVY LAUNCHER 

SpaceX Starship is made up of two stages, the Super Heavy booster and the Starship vehicle on top.

Super Heavy fires and gives Starship the boost it needs to reach orbit.

Once in space, Starship separates and continues its journey, while Super Heavy returns to land on the ground.

It is designed to be a reusable launch vehicle that could put humans on Mars, according to founder Elon Musk.

Super Heavy 

The first stage, or booster, of the next-generation launch system with a gross liftoff mass of over three million kg.

It uses sub-cooled liquid methane and liquid oxygen (CH4/LOX) propellants. 

The booster will return to land at the launch site on its six legs. 

Height: 70m (230ft) 

Diameter: 9m (30ft) 

Starship

Starship is the fully reusable spacecraft and second stage of the Starship system. 

It offers an integrated payload section and is capable of carrying passengers and cargo to Earth orbit, planetary destinations, and between destinations on Earth. 

Height: 50m (160ft)

Diameter 9m (30ft) 

Are there any other contenders to rival the SLS and Saturn V? 

Yes there are. Elon Musk has been trumpeting his much-anticipated Starship, which could be a game-changer for space travel.

Like Saturn V, SLS is not a reusable launch vehicle. But Starship will be.

It is being developed as a fully reusable transport system that is capable of carrying up to 100 people to Mars.

Starship is a rocket and spacecraft combination that when added together will stand at 394ft (120m). 

Because it will be reusable, the rocket will be able to return to the ground after launch and then blast off a short time later – much like an aircraft – once it has been re-filled with propellant.

This is a huge development because it brings down the cost of rocket launches and stops parts being discarded in the sea or burning up in the Earth’s atmosphere like with other launch systems. 

The spacecraft, which is also called Starship, will sit atop a rocket called Super Heavy. 

This will be powered by around 32 Raptor engines and should achieve more than 16 million pounds (70 Meganewtons) of maximum thrust. 

The rocket will also be able to lift at least 220,000 pounds (100 tonnes) of payload, and possibly as much as 330,000 pounds (150 tonnes), to low-Earth orbit.

Musk hopes Starship will be used for long-haul trips to Mars and back — which could take up to nine months each way. He is looking to install around 40 cabins in the payload area near the front of the upper stage. 

The first orbital test flight of SpaceX’s Starship is planned to launch as early as next month. 

It is not just the US that is looking to build mega rockets, however. 

China is also planning to develop the latest, biggest and boldest version of its Long March series of rockets.

The Long March 9 will be Beijing’s version of the SLS: a super heavy-lift rocket intended to launch large pieces of infrastructure into orbit and even help construct the joint China-Russia International Lunar Research Station. 

It will use the same fuel (methane-liquid oxygen, or methalox) as SpaceX’s Starship, while the two designs also share heavy-lift capabilities. However, beyond that their structure is wildly different.

Reports suggest that the Long March 9 will have a payload capacity to low-Earth orbit of around 308,000 to 330,000 pounds (140 to 150 tonnes).

There has also been talk that Russia is building its own mega rocket, too.

How other rockets compare: The fully reusable Starship will be able to carry a payload of more than 220,000lb into low Earth orbit, making it the largest rocket ever created

Minute by spine-tingling minute: How the Apollo 11 mission 53 years ago unfolded

At 1.32pm GMT on July 16, 1969, Apollo 11 took off from Kennedy Space Centre in Florida at the start of its mission to put the first man on the moon. It was only 66 years since the Wright Brothers had made the first powered flight.

Once the Saturn V rocket had put the astronauts on course for the moon, Apollo 11 consisted of three spacecraft: the command module; the service module Columbia in which the crew travelled; and Eagle, the smaller lunar module which would carry two men to the surface of the moon.

The crew was made up of its 38-year-old commander Neil Armstrong, 39-year-old Edwin ‘Buzz’ Aldrin, the pilot of Eagle (as a baby, his sister couldn’t pronounce ‘brother’ and called him ‘buzzer’), and former test pilot 38-year-old Michael Collins, whose job was to navigate and stay on board the command module. All three had written farewell letters to their wives in case they didn’t return.

‘Apollo 11, Apollo 11. Good morning from the Black Team.’ Ronald Evans, the Capsule Communicator (known as CapCom), gives the astronauts their wake-up call on the fifth day of the mission. They are some 240,000 miles away.

Each team working the ten-hour shift at Mission Control (the NASA nerve centre monitoring every aspect of Apollo 11) has a colour and the CapCom of each one is the only person who speaks directly to Armstrong and his crew. CapCom is always a fellow astronaut.

It takes 30 seconds for a sleepy Michael Collins to answer with a groggy: ‘Morning, Houston.’

The crew lift up the shades on the command module’s windows that keep the constant sunshine out when they need to sleep.

Today is the most important so far. If all goes to plan, in a few hours Neil Armstrong and Buzz Aldrin will be on the moon.

Four hundred thousand people employed by NASA and 4 per cent of U.S. government spending have got them to this point.

As they orbit the moon, Columbia is flying with the lunar module on its nose. Eagle looks like ‘an upside-down, gold foil-covered cement mixer’ in Aldrin’s words.

The crew are delighted their spaceships have serious names — unlike Apollo 10 whose lunar module was called Snoopy and command module Charlie Brown.

Anything that can float, such as pens, chewing gum and sunglasses, is attached to the walls of the module by hundreds of patches of Velcro. Armstrong, Aldrin and Collins are wearing slippers with Velcro on the bottom so they can fix themselves to the floor, sides or ceiling.

There are so many checklists the crew have nicknamed them ‘the fourth passenger’. Collins adds notes to his, to help future astronauts. The two on board computers each have far less memory than a mobile phone today.

WHO WILL SNAP UP A PIECE OF THE MULTI-QUADRILLION-POUND MOON PIE?

Worth a scarcely-believable multi-quadrillion pounds, the moon’s resources could solve the world’s energy crisis, meet the future demand for smartphones and electric cars, and get us to Mars and beyond.

But sitting there, 240,000 miles from Earth – and with no clear way of mining these precious metals, water and helium – these riches remain tantalisingly out of reach.

Not for long, however, with next week’s launch of NASA’s Artemis I moon rocket set to act as the starting gun for a return to the lunar surface and aspirations to create a human base on the moon.

Once that is in place, attention will turn to mining resources — first as a battle between nations such as the US and China, but before long many of the world’s biggest conglomerates.

They will all be hoping to grab a piece of the moon pie, which includes an estimated £168 billion ($206 billion) worth of water – vital for launching deep space missions from the lunar surface – billions of pounds of gold and £1.2 quadrillion ($1.5 quadrillion) of helium.

These are extremely rough estimates of value. No one knows quite how much water, metals and minerals exist deep within the moon, while the economics of supply and demand also have a huge bearing on putting a price on the riches. 

But there is definitely huge wealth at stake and there will be no shortage of companies trying to get their hands on it, even if it does require significant technological advances to extract the materials.

At least six countries and a flurry of private firms have so far publicly announced more than 250 missions to the moon to take place within the next decade. 

Many of these include plans for permanent lunar bases and are motivated in large part by ambitions to assess and begin utilising our lunar satellite’s natural resources.

Speaking to MailOnline, several experts shared their thoughts on what would be the main attractions for firms, ways they could mine the minerals and how it might benefit people on Earth.

Among them are basalt, iron, quartz and silicon, which could all be used for windows, stoneware and solar panels on Earth, while precious metals for electronics include platinum, palladium and rhodium.

Scandium, yttrium and other metals, which could be used in vehicle engines, to make glass or ceramics, electronic devices and radar systems, also exist within the lunar surface.

Scientists have even discovered titanium ore that is ten times richer than that found on Earth.

Rarer still is helium-3, a gas that could be used as a clean and powerful fuel for nuclear fusion reactors, while water trapped in lunar ice hidden deep in the shadow of polar craters could be turned into oxygen and rocket fuel.

WATER 

Considering there’s more than a billion cubic kilometres of water on Earth, it may seem strange to think of it being highly sought after.

But the reason it’s viewed as an almost priceless resource is because of what it could mean for the future of our civilisation and the potential to explore planets beyond our own.

That’s because it is very difficult to get a lot of water off Earth and into space due to its weight, with the cost of blasting one cubic metre of it into low Earth orbit coming in at an exorbitant £1 million (£830,000).

This means that having access to water already in space would be invaluable, not just for astronauts to drink and wash, but to use as rocket fuel — and NASA estimates there could be 600 million tonnes of water ice on the moon. 

Water is one of the most valuable resources on the moon and is mostly located in craters at the south pole, left, and north pole, right. The blue in the images represents areas of surface ice

As the water molecule is H20 – made up of two atoms of hydrogen and one atom of oxygen – it has the liquid oxygen and hydrogen needed to create rocket fuel.

This rocket fuel could then be used to blast a human spaceship from the moon off to Mars and beyond. 

So the question is, just how much water is on the moon?

Well, for starters the lunar surface is really dry. 

As a comparison, the Sahara Desert has 100 times the amount of water than what was detected in the lunar soil when NASA revealed conclusive evidence of water on our only natural satellite two years ago.  

The US space agency confirmed the presence of H2O in sunlit areas of the moon, which it said indicated that water was widely distributed across the lunar surface.  

‘The amount of water is roughly equivalent to a 12-ounce bottle of water in a cubic metre of lunar soil,’ said Casey Honniball, postdoctoral fellow at Nasa’s Goddard Space Flight Center in Maryland.

The first discovery was made from an airborne infrared telescope known as Sofia, which was on board a modified Boeing 747 that flies above much of Earth’s atmosphere and gives a largely unobstructed view of the Solar System. 

And just last month, a study confirmed that moon rocks collected by China’s Chang’e-5 lander do contain water, but not as much as scientists expected.

They found that the lunar soil had levels of H20 around 28.5 parts per million (ppm), which is relatively dry, even by the moon’s standards.

It was thought that this might have been because Chang’e-5 took the samples at a warm time of day. However, despite these discoveries, it is not yet clear whether this mineral-bound water could one day be used by humans on the moon.

If it could, the next question would be how to extract it.

One proposal from NASA’s Jet Propulsion Lab envisages beaming sunlight from giant reflectors located at mountain peaks that are exposed to near-constant sunlight into deep craters.  

Robotic mining vehicles would then be sent into the now-illuminated craters to recover water ice using the reflected solar energy.  

Professor Alex Ellery, Canada Research Chair in Space Robotics and Space Technology at Carleton University, wrote on the Conversation: ‘Water ice may be sublimed into vapour for recovery by direct thermal or microwave heating — because of its high heat capacity, this will consume a lot of energy, which must be supplied by the mirrors. 

NASA will send an ice-mining experiment to the moon’s south pole, scheduled for late 2022, using Intuitive Machine’s Nova -C lander (pictured)

‘Alternatively, it may be physically dug out and subsequently melted at barely more modest temperatures.’

However, Professor Ellery said there were more preferable options. 

‘Hydrogen reduction of ilmenite to yield iron metal, rutile and oxygen provides most of the advantages of exploiting water,’ he added.

‘Oxygen constitutes the lion’s share of the LH2/LOX mixture. 

‘It involves no great infrastructure: thermal power may be generated by modest-sized solar concentrators integrated into the processing units.’

Water is so valuable that our lunar satellite could become the refuelling station of the Solar System. 

A 2019 study calculated that ‘water produced on the moon has a current value of $10m per tonne, this value being based on the current costs to supply it from Earth.’

The research paper estimated that the value for the market over the next 30 years could be around £168 billion ($206 billion).

Dr Tony Cook, a research lecturer in the Department of Physics at Aberystwyth University, told MailOnline: ‘Water is present as ice in permanently shadowed craters at the lunar poles — more at the south than the north.  

‘It’s also buried under lunar soil slightly further away from the poles. Estimates vary but maybe around a billion metric tonnes. 

‘There are very tiny amounts of water on the sunlit parts of the moon at the 0.01-0.04 per cent level, perhaps more concentrated in volcanic glass which would make it easier to mine.’

METALS 
In a bid to become more environmentally-friendly and to tackle climate change here on Earth, there has been a huge growth in electric cars, wind farms and solar panels.

But these all require huge quantities of metals known as ‘rare earths’, known as such because of their scarcity.

The Apollo astronauts who brought back moon rocks in the 1960s and 70s showed that the lunar regolith also contains some of these resources, although Professor Ian Crawford, of Birkbeck, University of London, admitted they may be hard to extract.

If that were the case, it would make the financial cost of returning them from the moon less economically viable, although not impossible. 

‘It might be economically worse, but environmentally beneficial,’ he said.

The reason for this is because extracting rare earth metals such as neodymium – used in magnets – can cause high levels of contamination of the surrounding environment. 

So rather than do it on Earth, because of how damaging it is, the moon may be seen as a preferable destination for it. If that were the case, it would likely be a multi-trillion pound market.

Professor Crawford told MailOnline: ‘I would say that we don’t yet know enough about the moon to know whether lunar resources will be economically viable or not, and we are still very much in the exploration phase. 

‘I would see Artemis as part of this ongoing exploration activity.’

In a research paper on the topic, he added: ‘One would not go into space for a source of metals for use on Earth. 

‘Nevertheless, many metals will be essential for constructing industrial and scientific infrastructures on the moon itself and in cis-lunar space.’

Titanium also makes up about 1-10 per cent of the material on the surface, Dr Cook said, adding: ‘You will find more of this in the dark mare areas we see from Earth.’

The strong, lightweight metal is found in abundance in lunar dirt and is used in medical devices, consumer electronics, and even paint.

‘Like titanium, aluminium is present too – again as an oxide – [and] ditto for Iron,’ Dr Cook said.

Silicon, meanwhile, is abundant in all rocks, which Professor Crawford said could be important ‘in the context of the future industrialisation of space’.

‘It is of potentially enormous importance for the production of arrays of solar cells for the conversion of sunlight into electricity,’ he added.

There has also been speculation that billions of pounds worth of gold could be lying in wait under the lunar surface.

It is possible that some of the asteroids that have made their way to our lunar satellite would have carried gold with them as they travelled through space, which upon impact may have sunk far beneath the surface.

HELIUM

There is a huge energy crisis gripping not just Britain but much of the world. So much so that bills could hit £6,552 next April, according to the latest eye-watering forecast.

Nuclear fusion has been mooted as a potential alternative to fossil fuels and is seen as the ‘Holy Grail’ of energy, with scientists hoping to imitate how the sun creates energy by turning hydrogen into helium.

One way to do this is to take a rare type of hydrogen (called deuterium), which can be extracted from seawater, with an even rarer type of helium that is known as helium-3.

The latter is extremely rare on Earth but on some parts of the moon, including the Sea of Tranquility, there are helium-3 concentrations of 20 parts per billion in the surface material.

It is deposited there by solar wind because the moon has no atmosphere for protection.

The isotope is useful as an alternative to uranium for nuclear power plants because it is not radioactive.  

According to Dr Cook, it is at ‘concentrations about a thousand times greater than we find in our atmosphere’.

There is estimated to be around £1.2 quadrillion ($1.5 quadrillion) worth of helium-3 on the moon but, despite the excitement, Professor Crawford shared a word of caution.

He told MailOnline he ‘can’t see anyway that will be economic as an energy source for Earth’, despite the allure of such rich deposits.

TOURISM

It may not be one of the moon’s resources, but space tourism will certainly generate a lot of money. 

And with companies like Sir Richard Branson’s Virgin Galactic, Elon Musk’s SpaceX and Jeff Bezos’ Blue Origin all looking to take advantage of the money-making venture, there will be no shortage of options for those who can afford it to travel to places like the moon.

The financial services company UBS estimates the space travel market will be worth £2.5 billion ($3 billion) by 2030.

Blue Origin and Virgin Galactic, which are both licensed for passenger space travel by the Federal Aviation Administration, are open for ticket sales.

The former won’t say what it charges but Branson’s company is selling seats for around £380,000 ($450,000). At the moment these are just for trips into space, but soon enough they are likely to advance to journeys to the moon and perhaps even beyond.

HOW THE MOON PIE WILL BE SPLIT?

So how will the race for these resources be policed? 

Well, who owns the moon is a rather grey area.

However, the US has drafted the Artemis Accords, a non-legally binding set of principles to govern activity on the moon, Mars and beyond.  

NASA says the initiative is grounded in the 1967 Outer Space Treaty and forms the foundation of the space agency’s effort to kick-start mining operations of lucrative lunar elements. 

The UN Outer Space Treaty, which made clear that no nation state can claim the moon, was signed by more than 100 countries, including all the major spacefaring nations.

However, China and Russia have led opposition to the new Artemis Accords. They are jointly promoting an alternative project on the moon they say is open to all other countries called the International Lunar Research Station. 

NASA administrator Bill Nelson says that China wants to claim the moon as its own, adding: ‘We must be very concerned that China is landing on the moon and saying: It’s ours now and you stay out.’

Beijing, for its part, has rejected that assertion. 

The legal situation is equally ambiguous for any business seeking to make a profit from the moon’s resources. 

In 2015, the US passed the Commercial Space Launch Competitiveness Act, which made space mining legal, while other countries have introduced similar laws. 

But there have been clamours from experts to address the rules and laws so that there is more of an international consensus, amid fears it will turn into a free-for-all among the companies with the richest backing.

Companies are already investing in exploratory missions to further scope out what’s on the moon and the feasibility of extracting it. 

Among those selected by NASA are Lunar Outpost, ispace Japan, ispace Europe, and Masten Space Systems of California.

Firms like Astrobotic and Moon Express have also shared plans to send landers, experiments, and eventually cargo for paying customers to the moon. 

The new space race has well and truly begun.

WHAT IS THE MOON’S TOTAL VALUE?

That’s an almost impossible question to answer.

According to Professor Crawford, the value of resources ultimately depends on supply and demand. 

‘For example, we have recently seen the price of natural gas effectively triple, but the amount of natural gas on Earth has not changed,’ he told MailOnline.

Priceless: The value of resources on the mon ultimately depends on supply and demand

‘Moreover, if new reserves are brought to market, the price of commodities generally falls owing to the increased supply.

‘For all these reasons, you cannot add up all the perceived resources on the moon, convert to current prices, and present this as an estimate of their value. That would be meaningless!’

Professor Crawford added: ‘For the foreseeable future, probably the best way to look at lunar resources is how they may potentially help future habitation on the moon itself, and help with future space exploration, rather than their possible future value on Earth.’
