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.
The great commercial takeover of low Earth orbit
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.

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.

The most interesting work, however, has to do with NASA’s next-generation spacesuit for astronauts going to the moon—the eXploration Extravehicular Mobility Unit, or xEMU. It is ostensibly the successor to the spacesuits worn by Neil Armstrong, Buzz Aldrin, and other Apollo astronauts when they set foot on the lunar surface half a century ago. But it also incorporates what we’ve learned through the EMUs used in orbit during the space shuttle and ISS eras of human exploration, as well as the hard lessons from Apollo. The goal behind Artemis is to have people living and working on the moon. New spacesuits will be critical to ensuring that the experience is safe and comfortable. When NASA sends the first astronauts to explore near the lunar South Pole, moonwalkers will wear spacesuits provided by Axiom Space.
“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.
Testing of Next-Gen Spacesuit Underway
Since 2009, the Austrian Space Forum[44] has been developing "Aouda.X", an experimental Mars analogue space suit focusing on an advanced human–machine interface and on-board computing network to increase situational awareness. The suit is designed to study contamination vectors in planetary exploration analogue environments and create limitations depending on the pressure regime chosen for a simulation. Historically, a communications cap is worn under the astronaut’s helmet that contains earphones and microphones. The cap connects to the radio on the spacesuit and enables the astronaut to talk to other crew members and mission control. The communications cap is sometimes called the Snoopy cap for its resemblance to the aviator cap worn by the cartoon character. The new explorations suit includes an upgraded audio system inside the helmet that does not require the astronaut to wear a cap.

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.
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.
The suit is designed for improved mobility on the lunar surface compared to Apollo suits, and can fit a much wider range of astronauts. The AxEMU suit revealed at the Houston event leverages designs NASA developed for its Exploration Extravehicular Mobility Unit concept, a spacesuit the agency worked on internally before designing to shift to procuring suits as a service. Those designs are a significant departure from the suits currently used on International Space Station spacewalks or Apollo missions. During the reveal event, Jim Stein, chief engineer at Axiom Space, wore the suit and demonstrated being able to twist, bend, squat, and crouch down while wearing it. The new design has more joints, particularly in the lower half, enabling movements that would be impossible in the older design.
“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.
"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.
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.
Southern was a costume designer whose prior projects included wings for Victoria’s Secret angels and costumes for the traveling acrobat show Cirque du Soleil. Moiseev, on the other hand, had helped design five generations of Soviet and then Russian spacesuits at Zvezda, Russia’s spacesuit supplier, but had recently immigrated to the U.S. In NASA space suits, communications are provided via a cap worn over the head, which includes earphones and a microphone. Due to the coloration of the version used for Apollo and Skylab, which resembled the coloration of the comic strip character Snoopy, these caps became known as "Snoopy caps". Some of these requirements also apply to pressure suits worn for other specialized tasks, such as high-altitude reconnaissance flight.
