Chilled water flows through about 300 feet of tubes woven into this tight-fitting piece of clothing, working to regulate a spacewalker’s body temperature and remove extra heat. The David Clark Company may not be a household name among the fashionistas, yet it is instrumental in the world of innovation, especially as far as spaceflight is concerned. It was David Clark who first designed a lower-body compression suit to help sustain blood circulation, thus developing the world’s first anti-gravity space suit.

So to avoid any exposed gaps, designers minimized components like zippers or wrist disconnects, as well as seams where dust could infiltrate. “We’re looking at more of a whole garment that goes over the entire assembly, with small features where you can still perform operational checks and disconnect things during a contingency,” says Rhodes. “It’s like a whole shirt and whole pants that’s all one piece, without breaks where dust can get inside.” And for areas where there are breaks (like bearings), the team is working on developing and incorporating seals that should keep dust out. The xEMU is supposed to encourage normal walking as opposed to hopping, and make it easier to kneel down stably in one motion to work close to the ground—which wasn’t much of an option for Apollo astronauts. This is going to make it much easier for astronauts to conduct worthwhile science on the ground, like examining geological samples or setting up complex instruments.

These fictional suits vary in appearance and technology, and range from the highly authentic to the utterly improbable. The suits used for Gemini were more advanced than the Mercury suits; however, Gemini suits were simpler than today’s spacesuits. Instead, they connected to life-support systems on the Gemini spacecraft with a cord called an umbilical. After the Apollo mission, David Clark learned that the abrasive dust on the moon or Mars requires extra protection. “They were on the moon three days, but their suits came back super dirty,” Jacobs says.
Apollo 17 Anniversary – SUITS
Astronauts will be able to climb into a spacesuit from the back of the suit, which allows the shoulder elements of the hard upper torso to be closer together than the suits currently in use. The improved shoulder placement increases mobility and enables a better fit while also reducing the risk of shoulder injuries. The new lower torso includes advanced materials and joint bearings that allow bending and rotating at the hips, increased bending at the knees, and hiking-style boots with flexible soles. On the upper torso, in addition to the updated shoulder placement, other shoulder enhancements allow astronauts to move their arms more freely and easily lift objects over their heads or reach across their body in the pressurized suit.

Artemis astronauts will don next-generation spacesuits built by commercial providers and tailored for the lunar environment, where they will complete innovative NASA missions searching for ice and other volatiles near the lunar South Pole. The new suits will be equipped with upgraded life support systems and innovative tools, enabling astronauts to maximize science and sample collection during moonwalks at Earth’s 4.5-billion-year-old natural satellite. A space suit or spacesuit is a garment worn to keep a human alive in the harsh environment of outer space, vacuum and temperature extremes. Space suits are often worn inside spacecraft as a safety precaution in case of loss of cabin pressure, and are necessary for extravehicular activity (EVA), work done outside spacecraft.
Spacesuits
NASA calls a spacewalk an Extra-Vehicular Activity, or EVA, so this type of suit is often called an EVA suit. The spacesuits astronauts wear for walking in space are already aboard the station. Heavier and bulkier than launch-and-entry suits, spacewalking ensembles – called EMUs for extravehicular mobility units – have to function as a spacecraft unto themselves. Astronauts heading into orbit aboard Boeing’s Starliner spacecraft will wear lighter and more comfortable spacesuits than earlier suits astronauts wore.
The I-Suit is a space suit prototype also constructed by ILC Dover, which incorporates several design improvements over the EMU, including a weight-saving soft upper torso. Both the Mark III and the I-Suit have taken part in NASA's annual Desert Research and Technology Studies (D-RATS) field trials, during which suit occupants interact with one another, and with rovers and other equipment. Spacewalkers wear a high-tech backpack, or Portable Life Support System, that contains everything they need to explore the unforgiving space environment. Electricity, a fan, carbon dioxide removal system, water tank for the cooling garment, and a two-way radio round out the backpack’s essential gear.
The Space Suit Path to the Lunar South Pole
In 1998, the STS-88 crew aboard Endeavour conducted three spacewalks kickstarting the station’s assembly sequence, attaching cables, connectors, and handrails to mate the two modules — Zarya and Unity — forming the embryonic orbiting laboratory. Spacewalking was the essential element that moved the incredible journey of orbital assembly, operations, and science from blueprint to reality. For more than 40 years, NASA astronauts have performed spacewalks outside the space station for maintenance and upgrades while wearing the Extravehicular Mobility Unit (EMU) spacesuit design that debuted during the Space Shuttle Program in the 1980s. Spacewalks are some of the most physically and mentally demanding tasks an astronaut can do, with each excursion typically six to eight hours in duration. Since station’s inception, there have been more than 250 spacewalks at the laboratory in low Earth orbit, and that number grows every year as maintenance and discovery power on. The helmet on spacesuits built for spacewalks serves as a pressure bubble and is made of strong plastic to keep the pressure of the suit contained.
NASA and Axiom Space have unveiled the first major spacesuit redesign in four decades. Experiences enabling undergraduate students and K-16 educators to conduct science, engineering, mathematical, and technological experiments in a simulated microgravity environment or on a research-based platform. Artemis Generation Spacesuits was published by NASA’s Office of STEM Engagement as part of a series of educator guides to help middle school students reach their potential to join the next-generation STEM workforce.
Back in 2014, Italian astronaut Luca Parmitano was on a spacewalk when his suit began to leak water, flooding the helmet and nearly drowning him. Engineers later found that contamination had caused water from the cooling system to back up—trouble exacerbated by the fact that the water and cooling loops were in such close contact. So the xEMU now keeps those loops completely separate to avoid another such emergency from happening. The xEMU gets rid of the Snoopy cap for an audio system that’s embedded into the suit, voice activated to automatically pick up sounds as they’re spoken. That flight, if successful, will pave the way for a planned Artemis 3 astronaut expedition to the lunar surface - the first ever to the moon’s south pole - later in the decade.
The steps that spacesuit engineers and technicians follow to create their product are the same as those used in nearly every technological endeavor. The challenge is to design and build a full-scale, wearable model spacesuit to be used to explore the surface of Mars. The pages in this section of the Suited for Spacewalking Educator Guide outline a multifaceted technology education activity on spacesuits. This section includes an overview of the challenge in the Design Brief and includes Interface Control Documents so teams can communicate critical details about systems to other teams.
Axiom Space is truly building for beyond with the development of this next-generation spacesuit. The Axiom Space AxEMU spacesuit will be able to withstand the full range of temperatures at the lunar south pole. It will be able to endure the coldest temperatures, in the permanently shadowed regions, for at least two hours. In 2024 and 2025, the suit will be tested in a variety of ways to mimic the space environment. This includes testing at NASA’s Neutral Buoyancy Laboratory and in thermal vacuum chambers that expose the suit to the temperatures and vacuum experienced in space. This testing will aid engineers in ensuring that the suit is safe and complies with NASA requirements.
The xEMU also sports a new carbon dioxide scrubbing system that uses two different absorption beds (in this case, small cans made of lithium hydroxide that readily attract and trap carbon dioxide). While one is being used, the other can be exposed to the vacuum of space and emptied out—so carbon dioxide is constantly scrubbed without forcing astronauts to come back inside to clean the absorption beds. The oxygen tanks are higher-pressure systems that should deliver oxygen for longer periods of time than Apollo suits did. The only limitation now for how long someone can stay in the suit, theoretically, is battery power. The helmet on the suits for Artemis missions will also feature a quick-swap protective visor. The clear protective visor is a sacrificial shield that protects the pressurized bubble from any wear and tear or dents and scratches from the abrasive dirt of planetary bodies.
NASA is partnering with commercial providers Axiom Space and Collins Aerospace to provide next-generation spacesuits perfectly suited to NASA’s expanded mission portfolio. Expanding the commercial space services market is an important element of NASA's long-term goals of exploration in low Earth orbit and in deep space, including the Moon and Mars. The Mark III is a NASA prototype, constructed by ILC Dover, which incorporates a hard lower torso section and a mix of soft and hard components.
The quick-swap function means that astronauts can replace the visor before or after a spacewalk instead of sending an entire helmet back to Earth for repairs. NOVA chatted with Moiseev over Zoom about the literally astronomical price of spacesuit design, why mechanical counterpressure is still a dream, and what makes astronaut knuckles so exciting. Advanced spacesuits will protect astronauts on the Moon from the harsh lunar environment.
The new suits will allow astronauts to do things that the Apollo suits could not. The suits will be more abrasion-resistant to protect from potential damage by rough surface dust. Even with suits that don’t require much functionality — such as the IVA (intra-vehicular activity) suits that don’t leave the spacecraft — one sees the narrative of exploration being woven. “It’s really something to see how a company like SpaceX goes about creating an image of what space travel is going to be,” Lye says, referring to a suit recently unveiled by the company.
