That will mean more science and research time for NASA to seek vital answers for the challenges of future deep-space missions. Nasa on Wednesday unveiled the first prototype for a newly designed next-generation spacesuit specially tailored and accessorised for the first astronauts expected to venture back to the moon’s surface in the next few years. In the Anthropometry and Biomechanics Facility at NASA’s Johnson Space Center, astronauts undergo full-body, 3D scans while performing basic motions and postures expected during spacewalks. Spacesuits are not only a classic icon of human space exploration, they are also a personalized spaceship that mimics all of the protections from the harsh environment of space and the basic resources that Earth and its atmosphere provide. Astronauts have compared their current gloves to baseball mitts, not exactly conducive to the careful mechanical work often required on a spacewalk. So NASA took notice in 2009 when newcomers Nikolay (“Nik”) Moiseev and Ted Southern won second place at the agency-sponsored Astronaut Glove Challenge.

It should allow them to get ready more quickly in the suit when it's necessary, but also to lift materials or kneel down to study things when the situation calls for it. The big, puffy white moonsuits worn by Neil Armstrong and his fellow Apollo astronauts a half-century ago are out of fashion. Lunar haute couture now calls for something more form-fitting and comfortable for men and women. That desire for secrecy stems, in part, from the fact that NASA is now hiring private companies for work on various projects. Those commercial service providers are not locked into exclusive contracts with NASA and can make deals with other customers to sell their products and services. Before the first woman and next man take step on the lunar South Pole in 2024, NASA will test the new suits and several of its components on the International Space Station in a spaceflight environment to confirm the overall performance.

There’s also thermal protection to withstand the sharp temperature changes (from -250 °F in the shade to 250 °F under the sun). The main improvements Rhodes and his team are working on for the xEMU is to make sure astronauts’ hands are protected from extreme temperature changes and dust, and that they can handle lunar material safely. NASA is also figuring out how to make it easier for them to do simple tasks like grasp tools and operate small equipment. The suits also have a variable pressure system to give astronauts more flexibility when they need it.
Life Support System
Now we know that the greater danger is that the soil is composed of tiny glass-like shards, so the new suit has a suite of dust-tolerant features to prevent inhalation or contamination of the suit’s life support system or other spacecraft. The suit also is built to withstand temperature extremes of minus 250 degrees Fahrenheit in the shade and up to 250 degrees in the sun. The largest, most complex international construction project in space, the International Space Station, was designed and built by engineers thousands of miles apart on Earth — and assembled in space thanks to the daring of spacewalking astronauts.

The ones at the shoulders should allow astronauts to reach outward and lift objects more easily while reducing risk of injury to the upper body. There are finally bearings at the waist, hips, thighs, and ankles, creating much greater mobility in the lower body. “All of these together allow for very low-torque, low-energy mobility and motion,” says Rhodes. The outfits worn to the moon by Artemis astronauts will look very different from the bulky spacesuits of yore. The Artemis 1 mission, the inaugural launch of Nasa’s powerful next-generation rocket and its newly built Orion spacecraft on an uncrewed test flight around the moon and back, was successfully completed in December. Helping take a step forward in the agency’s goal to build a robust economy at the Moon by working with commercial service providers, Axiom Space hosted the event for students and media to ask questions and get a close-up look at the spacesuit.

Space suits have been worn for such work in Earth orbit, on the surface of the Moon, and en route back to Earth from the Moon. A self-contained oxygen supply and environmental control system is frequently employed to allow complete freedom of movement, independent of the spacecraft. More than 50 years of NASA expertise is going into the design of modern spacesuits that will protect and support astronauts as they reach iconic heights during forays in low-Earth orbit, the Moon, and worlds beyond. While the EMU spacesuit has far exceeded its planned design lifespan, NASA is eager capitalize on advanced spacewalking capabilities to achieve increasingly complex exploration goals.

“We have provided all of that technology, all of the drawings, all of the data, all of the test results for the community,” Vanessa Wyche, director of NASA’s Johnson Space Center, said of that earlier suit work. HOUSTON — As a Canadian used to standing at bus stops in -40 degrees, I'm no stranger to stiff gloves. So I was delighted when the gloves on Boeing's Starliner spacesuit allowed me to easily flex my fingers.
Dust mitigation
The integrated communication system has speakers mounted inside the helmet area and multiple embedded voice-activated microphones that automatically pick up the astronaut’s voice. On the back of the spacesuit is a backpack that houses the supplies and equipment to make the suit work. This backpack contains the oxygen that astronauts breathe and that pressurizes the suit. A fan circulates oxygen through the suit and life support system where the carbon dioxide that astronauts exhale is removed from the suit. The backpack provides electricity for the suit and holds a two-way radio for communication. The backpack also contains water for the cooling garment, a chiller to cool the water, and a pump that circulates the chilled water.
Helmet technology
The white outer layer reflects heat from the sunlight and is made of a fabric that blends three kinds of threads. One thread provides water resistance, another is the material used to make bullet-proof vests, and the third component is fire-resistant. Some suits are plain white and some have stripes to help tell one spacewalker from another. The spacesuit worn for spacewalks outside the International Space Station is called the extravehicular mobility unit, or EMU. NASA is currently developing a new suit that will be worn for spacewalks on Artemis missions called the Exploration Extravehicular Mobility Unit, or xEMU.
This will make it easier for astronauts to perform tasks like walking and picking things up from the ground while in the lunar environment. NASA astronauts have used the same basic spacesuit design since the Space Shuttle days, with the technology remaining essentially unchanged for 40 years. While the old suit design has proven itself over this time, it is particularly limiting in terms of the range of movement it allows. “When you’re designing a spacesuit, you want it to move freely and efficiently, with the least amount of effort possible, so we can be as near to shirtsleeve mobility as possible,” says Rhodes. The goal is to limit the amount of volume in the suit, because the more volume there is, the harder astronauts must to work to bend their joints, and that can quickly grow exhausting.
"This suit is an ascent-entry suit, which means that it's made to be on use in the interior of our vehicle," Tori Wills Pedrotty, Starliner spacesuit lead, told reporters here at JSC March 21. She also demonstrated how the last 40 years have seen substantial advances in spacesuit design since NASA's space shuttle ascent suits were designed. One simply needs to look back at the historic timeline of NASA spacesuits over 50+ years to recognize how much more sleek the SpaceX designs are, offering astronauts greater mobility and comfort at the inception of privatized space travel.
Apollo shoulder mobility was enabled by pleats in the fabric with cable pulleys that provided mechanical advantage to move the shoulders up and down but limited the ability to rotate the joint. The new shoulders minimize the effort required for full mobility and include bearings that allow full rotation of the arm from shoulder to wrist. The Portable Life Support System is the familiar backpack astronauts wear on spacewalks that houses the suit’s power and breathable air and removes exhaled carbon dioxide and other toxic gasses, odors and moisture from the suit.
The suit capitalizes on historical designs, meets NASA requirements for safety and functionality, and introduces cutting-edge innovations. Boeing unveiled its spacesuit design Wednesday as the company continues to move toward flight tests of its Starliner spacecraft and launch systems that will fly astronauts to the International Space Station. NASA experts defined the technical and safety standards by which the spacesuits will be built, and Axiom Space agreed to meet these key agency requirements.
