If the Artemis program proceeds as planned, humans will return to the moon by the middle of this decade. Public or private crewed missions to Mars in the next two decades are no longer limited to science fiction. When astronauts are on other worlds, what will they wear? NASA's efforts to design new spacesuits for the moon have proved equally challenging, despite the fact that Procuring giant rockets and futuristic spaceships for Artemis has been the most well- publicized hurdle. The space agency has spent hundreds of millions of dollars on new suit designs. NASA chose two companies to craft the next generation of haute couture for the high frontier after all the failed attempts.
As part of NASA's Exploration Extravehicular Activity Services (xEVAS) contract, two companies will independently develop new space suits. NASA plans to purchase its suits from the two companies as a service, which will allow them to make and market additional suits for non-NASA commercial missions, as well as freeing them to make and market additional suits for NASA. The first Artemis landing will take place in the year 2025. There will be two astronauts, one man and one woman, who will wear suits from one of the two companies, on that mission. The suits will be supplied by whichever company isn't chosen for the first landing.
The director of NASA's Johnson Space Center said in a press conference on June 1 that it was a historic day for the center. When we reach the moon, history will be made with these suits.
The existing Extravehicular Mobility Unit (EMU) suit used on the International Space Station is too heavy and rigid to be used on the lunar surface. More than 40 companies registered their interest, but only two of them submitted their final proposals by the December 2020 deadline. NASA gave high ratings to both the proposed suit by Collins and the proposed suit by Axiom.
The public-private partnership will allow both suit manufacturers to offer their services outside of the space agency, potentially to visitors to private space stations. Mark Greeley is the xEVAS Program Manager for Axiom. He says that the AxEMU is able to support spacewalks in any environment. Collins is going to do the same thing. Dan Burbank is a senior tech fellow at Collins and a former astronauts. The suit should be suitable for both private and commercial astronauts.
It has been a difficult process to get to this point. The Z-1 prototype spacesuit was unveiled by NASA in 2012 and was green and white. The Z-2 was later changed to the Z-2. The Exploration Extravehicular Mobility Unit (xEMU) was supposed to be used for the Artemis missions, but an audit by the agency's Office of Inspector General found the suits wouldn't be ready in time. According to a space historian at the National Air and Space Museum in Washington, D.C., there was concern that this was a never ending process. The manager of the Extravehicular Activity and Human Surface Mobility Program at NASA's Johnson Space Center said that they could decide how much of NASA's designs they wanted to use.
The designs of the space suits are still being worked on. The process dictated that both of them had to show their suits could meet the requirements. The design was left to them to decide. The objectives of the Artemis missions are different from those of the Apollo missions. The dark depths of craters that could contain water ice will be explored by Artemis astronauts, who will spend more time on the moon. The new suits must meet the needs of NASA, not only because of the awkward waddling and clambering provided by the Apollo program, but also because of the need for more mobility. Foster is a space historian at the University of Central Florida. I don't want anyone to be left out of the chance to fly on Artemis because of their body type.
The suits need to be able to conduct at least six lunar- surface excursions per mission. Each will last more than eight hours. The total prep time for venturing outside of a lander or habitat must be no more than 90 minutes.
Collins and Axiom are designing their suits. The new designs could be attached to a special NASA-prototyped airlock called a suit port, instead of being put on inside an airlock and then exiting a spaceship. Burbank says it's possible to bond the outer portion of your suit to the structure and then open it. The amount of lunar regolith that is tracked back inside can be harmful. Burbank says using a suit porteliminates the regolith hazard. The exterior of the suit doesn't see the inside of the spaceship.
Reflecting on part of NASA's objective for Artemis to send the first people of color and the first women to the moon, the new suits must, in a sense, also be "one-size-fits-all." A spacesuit designer at the Rhode Island School of Design says that NASA had to delay an all- women spacewalk because they didn't have the right suits. The new suits by Collins and Axiom will fit a lot of different styles. This requirement is not currently known.
The main goal of the Artemis missions is to collect lots of samples. The suits need to have accessories to achieve this goal. They are intended to be extremely maneuverable and will allow astronauts to move more naturally on the moon. Burbank says that during the Apollo days, it wasn't possible to allow your hips to move against your shoulders. It was impossible for you to take your hips out of alignment. It's possible to do that with this spacesuit. The lower mass of the suits will make them easier to use for extended periods. Burbank did push-ups in the new suit. It would be impossible in the suits we have.

There are a lot of high bars for the suits to hit. They can't make the astronauts listen to sounds above 115 decibels. They need to be strong enough to prevent micrometeoroids from piercing the exteriors. The suits must include tools to help Artemis crew members carry and plant a flag, inspired by the ceremonial unfurling of American stars and stripes by each set of Apollo moonwalkers. The suits have to be able to clear up to half a liter of vomit from a moonwalker's eyes, nose and mouth.
After being left on the lunar surface, the suits need to remain functional for as long as three years. It could allow astronauts on future missions to reuse the suits left behind instead of bringing their own. The landing sites could allow us to collect and reuse them. Digital heads-up displays inside the helmet are one of the new technologies being looked at by both Collins and Axiom. Burbank wants to show information to the crewmember about the health of the suit, the health of their crewmates and the path to their rover. It's possible that you could have the ability to combine the two.
The suits need to be designed for a new era of exploration. The Apollo missions focused on the sun-bathed regions of the near side of the moon, while Artemis missions will go to the moon's south pole. Some of the moon's permanently shadowed regions may be explored by astronauts in a way that the sun never gets to their depths. The lowest surface temperatures found on the moon during its two week long lunar night can be as cold as the inside temperature. Water ice, either frozen on the surface or mixed into the lunar soil, could be accessed and used as drinking water or rocket fuel, according to observations from the moon. The new suits need to operate in these locations for at least two hours to give astronauts a chance to see it.
Hundreds of millions of tons of water ice is buried at the south pole. Human presence on the moon requires water. Spacesuits are going to be needed to do the resource extract.
The moon is not the only place where astronauts can wear these garments. Both are being designed with future modifications in mind. While some development remains, the company is investigating how to cope with that planet's tenuous atmosphere and its larger gravity. The lunar variant of the suits will be ready for the first Artemis moon landing. Development delays with the rockets may make that deadline slip, of course, which could be for the best because readying such ambitious suits in such a short time frame seems challenging. Lewis said there was a lot of work to be done. When humans set foot on the moon again, that work should make sure they have shiny new clothes to use in the vomit removal system.
