Axiom Space is responsible for the design, development, qualification, certification, and production of flight training spacesuits and support equipment, including tools, to enable the Artemis III mission. The company will test the suit in a spacelike environment prior to the mission. NASA maintains the authority for astronaut training, mission planning, and approval of the service systems. The earliest space fiction ignored the problems of traveling through a vacuum, and launched its heroes through space without any special protection. In the later 19th century, however, a more realistic brand of space fiction emerged, in which authors have tried to describe or depict the space suits worn by their characters.

Helmets also contain a small foam block that astronauts can use to scratch their noses. Outside of this bubble is a protective visor that keeps the pressure bubble from getting bumped or scratched. The sun visor has a special gold coating that works like the astronaut’s sunglasses. Together, the movable sun visor and sun shades protect the astronaut from the sun’s strong rays, while still allowing a clear visual field.
Suit Up for Mars
On launch day, astronauts will don the suit in the historic Crew Quarters before striding across the Crew Access Arm at Space Launch Complex 41 and boarding a Starliner as it stands atop a United Launch Alliance Atlas V rocket. The new helmet has features like a light band over the helmet bubble to enable better vision and an HD video camera on the side so astronaut POV video can be livestreamed back to Earth. The boots were another area that needed to be particularly well insulated to enable astronauts to work in the cold conditions of permanently shadowed regions of the Moon. Another major difference from the previous suit design is that the astronaut enters the AxEMU from the back rather than getting into the bottom then top as before. They are designed to fit a broad range of potential wearers, accommodating at least 90% of the US male and female population, Nasa said. They also will incorporate advances in life-support systems, pressure garments and avionics.
Why Do Astronauts Need Spacesuits?
Where Vi and Vf are respectively the initial and final volume of the joint, P is the pressure in the suit, and W is the resultant work. However, because a minimum internal pressure is dictated by life support requirements, the only means of further reducing work is to minimize the change in volume. NASA explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery. NASA SUITS challenges undergraduate or graduate students to design and create spacesuit information displays within augmented reality (AR) environments. Mars also has more gravity than the Moon, so the suits worn on Mars cannot add too much additional weight.

They quickly found it difficult to walk around normally in microgravity, and they were also very careful to avoid any dangers. The solution is to use bearings, since they rotate around a single point and ensure a constant amount of volume. The old Apollo suits used bearings only in the arms, because it was basically a multipurpose suit (used for both launch and entry, as well as lunar exploration). It needed to be light enough to accommodate all these different situations, and too many bearings could have weighed it down. An engineer-artist duo wants to create sleeker spacesuits that meet the challenges of a low-pressure environment while offering more mobility—and looking cool.
Later comic book series such as Buck Rogers (1930s) and Dan Dare (1950s) also featured their own takes on space suit design. Science fiction authors such as Robert A. Heinlein contributed to the development of fictional space suit concepts. During exploration of the Moon or Mars, there will be the potential for lunar or Martian dust to be retained on the space suit. When the space suit is removed on return to the spacecraft, there will be the potential for the dust to contaminate surfaces and increase the risks of inhalation and skin exposure. Astronautical hygienists are testing materials with reduced dust retention times and the potential to control the dust exposure risks during planetary exploration.
Or perhaps it’s the gloves, since they must simultaneously protect astronauts’ hands, which feature intricate musculature and more than 25 joints, while also allowing for precise and smooth range of motion. The hard upper torso is lightweight but strong and connects the inside of the suit with the appropriate systems in the portable life support system. It is shaped like a sleeveless shirt and connects to the arm assembly that covers the arms and joins the gloves.
The upper torso of the new exploration suits will have a rear-entry hatch to allow astronauts to climb into the back of the suit. Astronauts did not go on spacewalks then, and the Mercury suits were worn only inside the spacecraft. At an event in Houston March 15, Axiom revealed the design of the suit, called the Axiom Extravehicular Mobility Unit (AxEMU), it will provide to NASA for missions starting with Artemis 3 in the mid-2020s. The suits will be worn by astronauts during their excursions on the lunar surface.

The precise look of the suits, however, remained a closely guarded trade secret. Those on display came with an outer layer that was charcoal gray with dashes of orange and blue and Axiom’s logo on the chest – intended to obscure Axiom’s proprietary outer fabric design. All 12 Nasa astronauts who landed on the moon during a total of six Apollo missions from 1969 to 1972 were white men.
Astronauts returning to the Moon in September 2026 as part of the Artemis III mission will wear an Axiom Extravehicular Mobility Unit (AxEMU) to enable more exploration of the lunar surface than ever before. This next-gen spacesuit will allow astronauts to walk on the Moon for the first time in over 50 years. A spacesuit is much more than a set of clothes astronauts wear on spacewalks. The formal name for the spacesuit used on the space shuttle and International Space Station is the Extravehicular Mobility Unit, or EMU. The spacesuit protects the astronaut from the dangers of being outside in space.
Nasa and the Canadian Space Agency plan to announce the four astronauts chosen to fly as early as next year on Artemis 2, another out-and-back mission.

Created by Axiom Space, the new suit is designed to improve mobility for astronauts working on the lunar surface. It was a tough lesson about the need to make sure that suits are designed properly to accommodate people of all sizes. The agency has decided that with the xEMU, they’re leaving nothing to chance.
Some keep oxygen in the suit while others protect astronauts from space dust. The suits protect astronauts from getting too hot or cold and also give astronauts oxygen to breathe while they are working in space. Space dust may not sound very dangerous, but when a tiny object is moving many times faster than a bullet, it can cause injury. Spacesuits also protect astronauts from radiation in space, and are equipped with special, gold-lined visors to protect astronauts’ eyes from bright sunlight. The suit features a large clear helmet bubble for enhanced fields of view, with lights and camera integrated into it.
For all that, however (and that is a big deal), the total effect is still very much within the recognizable spacesuit tradition, at least to the untrained eye. Explore 50 years of spacewalking history, beginning in 1961, in this pictorial timeline of milestones reached … and those to come. “We slogged through some of the real engineering challenges and now we are getting to the point where those challenges are largely behind us and it’s time to get on to the rubber meeting the road,” Ferguson said. ADU maker Cosmic is introducing 100 ADUs for California homeowners starting at $279,000, outfitted with solar power storage and water reclamation systems to make off-grid living a reality. Designed + built by students at IAAC, MO.CA (MOBILE CATALYST) is a modern, self-sufficient mobile home with all the amenities you need to live on the road. Nasa promises that subsequent Artemis missions will include the first person of colour on the moon.
The latest in moon-wear was displayed at the Johnson Space Center in Houston during an event hosted for the media and students by Axiom Space, the Texas-based company contracted by Nasa to build suits for Artemis, successor to the Apollo moon program. NASA chose to use a commercial services contract for development of the new spacesuit, whereby NASA purchases moonwalking services from Axiom Space. Under this model, the company is encouraged to pursue other commercial customers for their moonwalking services. This mutually beneficial approach helps bolster an emerging commercial market and grants NASA the right to use the data and technologies developed under the contract for future exploration efforts. Last June, NASA announced it had chosen Axiom and Collins Aerospace—the only two companies to submit bids—to develop new spacesuits to be worn on the moon and on the ISS.
The new suit prototype — called the Axiom Extravehicular Mobility Unit, or AxEMU — is based on some of the developments made by NASA for its Exploration Extravehicular Mobility Unit (xEMU) prototype. The focus of the developments was on issues like thermal requirements to deal with the cold temperatures found on the Moon’s south pole, as well as improved mobility and safety requirements. Meanwhile, the xEMU is retaining some life support and safety features that are tried and true. There’s protection from micrometeorites based on a similar design for the current orbital EMUs.
