The prototype includes a dark gray cover, which was designed by costume designer Esther Marquis, who worked on the TV series For All Mankind, but the actual suit will be white for thermal reasons. The moon’s surface hasn’t been exposed to the kind of weathering Earth’s geology has faced. As a result, the lunar soil is very coarse and jagged, and it sticks to everything (yeah, I know I sound like Anakin Skywalker). It contaminates inner layers of the garment and any parts that are supposed to detach, and causes general wear and tear to the exterior of the suits. The xEMU has bearings that are lighter and hew closer to the joints than ones used for previous EMUs.
Life Support System
It features a soft torso versus the hard torsos seen in previous NASA EVA space suits, which reduces mass.[60] It has been labeled the "Buzz Lightyear suit" due to its green streaks for a design. Axiom is best known for private astronaut missions to the ISS and plans to add commercial modules to the station as a precursor to its own commercial space station. Mark Greeley, program manager for extravehicular activity at Axiom, said the company will use a similar design for suits it plans to develop for space station spacewalks, with differences in elements like boots and gloves. Artemis astronauts will be more nimble than ever before with mobility enhancements in the new suits. Bunny-hopping Apollo astronauts are fun to watch, but the exertion required to move around that way was more than NASA would have liked for their explorers who were 250,000 miles from home. The pressure garment is the human shaped portion of the spacesuit that enables astronaut mobility and protects their body from the external environment including, extreme temperatures, radiation, micrometeoroids, and reduced atmospheric pressure.

The last time humans set foot on the moon was more than 50 years ago, during the Apollo 17 mission in December 1972. And the last time NASA designed new spacesuits was roughly four decades ago, for astronauts to wear on the Space Shuttle. Today, those suits are the ones in use on the International Space Station (ISS). The first astronauts to walk on the moon since the 1970s will do so wearing sleek, new spacesuits. Axiom Space, the private company NASA tapped to design moonwalk suits for the Artemis 3 mission, unveiled its prototype on Wednesday at NASA’s Space Center Houston.
Soft suits
At altitudes above the Armstrong limit, around 19,000 m (62,000 ft), water boils at body temperature and pressurized suits are needed. The first piece of a spacesuit that astronauts put on is a special cooling garment made of a stretchy spandex material and water tubes. About 300 feet of tubes are woven into this tight-fitting piece of clothing that covers the entire body except for the head, hands and feet. Chilled water flows through the tubes near the spacewalker’s skin to regulate body temperature and remove extra heat during the spacewalk, which typically lasts multiple hours. Vents in the garment draw sweat away from the astronaut’s body and help with circulation inside the spacesuit garment. Before donning the actual spacesuit, the first piece that astronauts put on is a special cooling garment made of a stretchy spandex material and water tubes.
Operating pressure
Designed to fit 90 percent of men and women in the United States, the new suits will also help NASA reach its goal of landing the first woman on the moon during Artemis 3.
The helmet on the suits that will be worn for Artemis missions will feature a quick-swap protective visor that protects against the abrasive dirt of planetary bodies. The helmet for these new suits also features an elliptical shape that provides a better view of the ground around the spacewalker’s feet. Spacesuits designed for the Apollo program had to do things the first suits did not. And, unlike the other suits, the Apollo suits had boots made to walk on a rocky surface. The Apollo suits also contained a life support system, similar to the Portable Life Support Subsystem on the current suit. Having a life support system on the spacesuit allowed the astronauts to explore away from the lunar lander.
When astronauts step onto the moon in 2025, the dark cover layer will be swapped for a white insulation layer for thermal protection. On Episode 280 of Houston We Have a Podcast, hear from a spacesuit systems engineer who explains what will be needed in the design and operation of a spacesuit on the Red Planet. This is the tenth episode in a reboot of our series about a human mission to Mars. The Apollo spacesuit was basically a one-piece suit, and each was custom tailored to fit every moonwalking astronaut.
A fully equipped spacesuit used during spacewalks is actually a miniature spaceship shaped like a human body that protects the astronaut from the dangers of being outside a vehicle while in space or on the Moon. Spacewalking astronauts face radiation, dust, debris, and extreme temperatures. Temperatures on spacewalks may vary from as cold as minus 250 degrees Fahrenheit to as hot as 250 degrees in the sunlight. The suits provide the proper pressure for the body and supply astronauts with water to drink and oxygen to breathe. Next-generation spacesuits designed by Axiom Space and Collins Aerospace will be built to accommodate the diverse physical characteristics of NASA astronauts, offering a wide range of sizes and a high-mobility upper torso for maximum range of motion. Launch-and-entry suits worn by space shuttle crews tended to run about 30 pounds (13.7 kg), while Boeing's version is only 20 pounds (9 kg).

The primary components of the pressure garment are the upper torso, helmet, lower torso and cooling garment. The lower section of the suit is made up of spacesuit pants, boots and the lower half of the waist closure. A metal body-seal closure connects the lower torso to the hard upper torso. On the new suits that will be used for lunar surface missions, the lower torso includes advanced materials and joint interfaces that allow bending and rotating at the hips, bending at the knees, and hiking-style boots.
No one has ever died because of a faulty spacesuit, but that doesn’t mean current models are perfect. Whether it’s for launch into space or reentry back to Earth, or for an extravehicular activity (EVA, colloquially known as a spacewalk), astronauts have never been completely satisfied with the gear they are forced to put on for missions. Following Artemis III, the agency will compete future Artemis mission services under the Exploration Extravehicular Activity Services (xEVAS) contract.
“Dust is going to be a pretty tricky problem to deal with,” Ralston said. That includes ways to prevent dust from adhering to the suit in the first place, and then, when dust dues stick to it, keep it from coming off when the astronauts go back inside their lunar lander. The full suit, which includes an integrated shoe, weighs about 20 pounds with all its accessories – about 10 pounds lighter than the launch-and-entry suits worn by space shuttle astronauts.

In order to retain a better sense of touch for the astronauts, the fingertips of the gloves were made of silicone. With the shuttle program, it became necessary to be able to operate spacecraft modules, so the ACES suits featured gripping on the gloves. EMU gloves, which are used for spacewalks, are heated to keep the astronaut's hands warm.
They’re tailored to offer astronauts more flexibility and mobility when they set foot on the lunar South Pole, which is scheduled to take place as soon as 2025. Is it the shoulders, where a few inches’ difference in joint placement can lead to a repetitive stress injury? Is it the outer layer, which must protect its wearer from micrometeorites, tiny flecks of metal, rock, or paint hurtling thousands of miles per hour through space?
Axiom won the $228.5 million contract in September to build the new moon suits. A few months later, Collins Aerospace nabbed the $97.2 million contract to configure new spacesuits for spacewalks outside the ISS. Astronauts will still wear a diaper-like garment during spacewalks that is a combination of commercial products stitched together for maximum absorption. Although space explorers generally prefer to not use it, it is there in the event they need to relieve themselves during a spacewalk that can last many hours. With a compression spacesuit we have to be careful because if I pick up something and my biceps increase in size, the compression level will be different.
However, 21st century moonwalkers will be able to accomplish much more complex tasks than their predecessors, thanks to strides in technological advances that started even before the Apollo program. The first full-pressure suits for use at extreme altitudes were designed by individual inventors as early as the 1930s. The first space suit worn by a human in space was the Soviet SK-1 suit worn by Yuri Gagarin in 1961. Spacesuits similar to the Apollo suits were used on the Skylab space station. Like the Gemini suits, the Skylab suits connected to life support systems on the spacecraft via an umbilical.
