That includes a “rear entry” design for the suit, explained Russell Ralston, deputy program manager for extravehicular activity at Axiom, during the event. A hatch in the back of the suit opens up and the astronaut slides into the suit. It’s possible for an astronaut to get into the suit on their own, closing the hatch behind them. WASHINGTON — NASA and Axiom Space unveiled a prototype of the spacesuits that astronauts will wear on Artemis missions to the moon. Boeing first unveiled its spacesuits in 2017, with features including wrap-around glass in the helmet and touchscreen-sensitive gloves. The overall suit is intended to be "lighter and more flexible through use of advanced materials and new joint patterns," NASA officials wrote at the time.
Current spacesuits won’t cut it on the moon. So NASA made new ones.
With this new mobility, astronauts will be able to walk on the lunar surface, instead of doing the “bunny-hop” developed by Apollo moonwalkers. However, like a set of clothes, different suits serve different purposes. Space exploration usually includes two different kinds of spacesuits, both of which protect astronauts from the dangers of their mission. One kind is worn inside a spacecraft during launch and ascent to space, and again on the way home during re-entry into Earth’s atmosphere as well as during landing.

"I really like these suits," Williams said during a press conference here at JSC on March 22. "We worked with the company, David Clark, through Boeing to get the suits squared away for us ... I think they're really nice." Back in March 2019, NASA canceled plans for the first all-woman spacewalk because there weren’t enough correctly sized spacesuits—only larger ones were available.

A spacesuit is more like a miniature spacecraft you wear around your body than an item of clothing. It’s pressurized, it’s decked out with life support systems, and it’s likely to look pretty cool. The company said the suits to be worn on the lunar south pole by astronauts will be white because that is the best colour to reflect the harsh sunlight on the moon’s surface and protect the wearer from extreme heat. With the Artemis program, NASA wants to put humans back on the moon for the first time in more than 50 years.

The program, named for Apollo’s twin sister from Greek mythology, is aimed ultimately at establishing a sustainable lunar base as a stepping stone to future human exploration of Mars. And we’ve learned together on our designs—we created something totally new. First, if we have direct pressure on the body from the fabric, the fabric compresses our body. So, on my arm, we have compression here [gestures to bicep and forearm.] But here [elbow] we have concavity, and here [wrist] we have concavity. On Wednesday, just a week after the end of the Paris fashion collections and with the sort of sonic crescendo attached to the most extravagant runway shows, NASA unveiled the new Artemis III lunar spacesuit at Space Center Houston. Which is to say, the first real reconsideration of the spacesuit in 40 years.
What Is a Spacesuit?
Regardless of the leaps in space suit advancements, astronauts still must conduct complex science and operational activates while wearing their own personal spacecraft. Practicing on Earth helps, but the difference in gravity, pressure and environmental exposure is difficult to truly replicate on the ground. At first glance, NASA’s new spacesuit that will be worn on Artemis missions might look like the suits that astronauts use for spacewalks outside the International Space Station today.
Testing of Next-Gen Spacesuit Underway
“It got into the zippers and everything.” The company then introduced a new outer space lawyer called an environmental protective garment, designed to protect against micrometeoroids, small flecks of rock or paint. For de Monchaux, space suit design is more than innovation and technology — he sees it as a significant development in the national identity. There was an “explicitly encouraged relationship between the closing of the Western frontier at the end of 19th century and the opening of frontiers of aviation,” he says. It was very explicitly and carefully redefined as upward and outward.” With space deemed “the final frontier,” de Monchaux says that Americans strive to discover, explore and settle new territories. One challenge for the suit design is dealing with lunar dust that can stick to materials and degrade joints and seals.
Glove technology
The restraint layer is shaped in such a way that bending a joint causes pockets of fabric, called "gores", to open up on the outside of the joint, while folds called "convolutes" fold up on the inside of the joint. The gores make up for the volume lost on the inside of the joint, and keep the suit at a nearly constant volume. However, once the gores are opened all the way, the joint cannot be bent any further without a considerable amount of work.
When comparing the suits worn during the mission above with their 2017 preview revealed via Elon Musk’s Instagram (shown below), one can see little has changed at the surface level. NASA established the foundation for the AxEMU with the agency’s Exploration Extravehicular Mobility Unit (xEMU) prototype development efforts that advanced spacesuit designs for multiple destinations. Leaning on NASA’s prior development efforts is helping Axiom Space reduce technical and schedule risk. The restraint layer goes outside the bladder, and provides a specific shape for the suit. Since the bladder layer is larger than the restraint layer, the restraint takes all of the stresses caused by the pressure inside the suit. Since the bladder is not under pressure, it will not "pop" like a balloon, even if punctured.
Novel ingress and egress approaches, such as suitports, are being explored as well. Astronauts must be able to work with and pick up objects while wearing spacesuit gloves. Gloves protect astronauts from the space environment and are made so spacewalkers can move their fingers as easily as possible. The fingers are the part of the body that gets coldest in space, and the gloves on spacesuits are equipped with heaters to keep fingers warm while still allowing dexterity to use tools. As the agency began to plan for space exploration, NASA needed to transition from full-pressure suits to spacesuits, which were a significant step in protecting humans. Like the spacesuits used in Apollo, the new spacesuits will have to let astronauts work safely on the surface of another world.
Doug Hurley and Bob Behnken, the astronauts who went up on the Crew Dragon to the ISS in May, remarked that they were extremely comfortable and easy to get on and off. Suits that are worn during takeoff and reentry are designed to protect astronauts from fire, and they plug into seat umbilicals that carry oxygen and cool air in case the cabin depressurizes for some reason. Soon, NASA will no longer rely on the Extravehicular Mobility Unit, or EMU, spacesuit design that debuted during the Space Shuttle Program in the 1980s for its spacewalking crews. More than 50 years of spacesuit expertise will inform the design modifications for the new suits as they get an upgrade for NASA’s growing mission portfolio. In 2012, NASA introduced the Z-1 space suit, the first in the Z-series of space suit prototypes designed by NASA specifically for planetary extravehicular activity. The Z-1 space suit includes an emphasis on mobility and protection for space missions.
“There are so many dimensions to us, such incredible dexterity,” said Lye. Together with his students, he created modular suits so that parts could be chosen to fit a particular astronaut. Lye’s recent suit design project was for NASA’s Hawaii Space Exploration Analog and Simulation, a Mars simulator on the slopes of a Hawaiian volcano. If an astronaut gets strapped in but can’t reach the switches or work the touchscreen, the spacesuit would not be effective. That’s why astronauts have spent some of their time sitting inside a Starliner mock-up wearing the spacesuit.
“The association between shiny stuff and things that are not of this world goes back to the dawn of civilization,” de Monchaux says, giving examples of the silver and gold on clothes worn by bishops and priests. The BF Goodrich designers who created one of the first space suits surely did paint it silver. However, for practical reasons, silver, which attracted too much light, was soon changed to a less-reflective white. This change caused the trend on Earth of associating the color white with all space-related things. The design unveiled at the event is not identical to what Artemis astronauts will wear. The company elected to put a customized cover layer, black with blue and orange accents, on the suit for this event “to conceal the suit’s proprietary design,” the company explained.

The AxEMU spacesuit will provide astronauts with advanced capabilities for space exploration, while offering NASA affordable, commercially developed human systems needed to access, live, and work on and around the Moon. Evolving NASA’s Exploration Extravehicular Mobility Unit (xEMU) spacesuit design, the AxEMU is built to provide increased mobility and greater protection to withstand the harsh environment of the lunar south pole. The AxEMU spacesuit will also integrate with specialized tools developed by Axiom Space for exploration and scientific opportunities. Fortunately, though, the flurry of new activity in space has meant we’re seeing more innovation in spacesuit design and performance than ever before. The emergence of new private vehicles like SpaceX’s Crew Dragon and Boeing’s Starliner means NASA astronauts going to the International Space Station are wearing new spacesuits that are extremely sleek and chic.
The two main parts of a spacewalk spacesuit are the pressure garment and the life support system. The pressure garment is the human shaped portion of the spacesuit that protects the body and enables mobility. The primary components of the pressure garment are the cooling garment, upper torso, lower torso and helmet.
NASA is using the contract to meet the agency’s spacewalking needs for both the Moon and the International Space Station. The agency recently awarded a task order to Collins Aerospace, who is also competing within the xEVAS contract, to develop new spacesuits for astronauts to wear during spacewalks on the space station. Both vendors will compete for future spacewalking and moonwalking services task orders.
