“Our suits aren’t gendered, so we have one suit for both males and females,” David said. And we found fabric we can do both imaging and elemental targeting with. We got Johnson [Space Center, where spacesuits are designed] involved too, and we like to be one big NASA family. In March, a spacewalk that was to be the first conducted by two women, Christina Koch and Anne McClain, had to substitute a male astronaut, Nick Hague, because there were not two spacesuits on the station that fit both women. It is NASA’s new suits will be made in a wider range of sizes than had been previously available. The deadline for proposals is Nov. 1. That means the suits feel heavier on Mars than they would in other environments — and Current complete spacesuits including life support systems weigh around 300 pounds, and although the next-generation suits are still having their weight finalized, they’ll probably be similar. “It could display things like procedures, or camera views. But the communication delay with Mars would make this time-consuming and inefficient. You have more erosion from the wind and storms, so the dust isn’t quite as sharp as on the moon. In addition to updated spacesuits, the agency does not currently have a spacecraft capable of landing on the moon. We’ll seek refuge in here.”Each outfit shared similarities with its utilitarian predecessors worn by earlier astronauts. To keep astronauts safe while they explore the planet, we’ll need sophisticated habitats, life support systems, and communications. Today, NASA unveiled its designs for future spacesuits that astronauts will wear during trips to the lunar surface. Astronauts heading into orbit aboard Boeing’s Starliner spacecraft will wear lighter and more comfortable spacesuits than earlier suits astronauts wore. We don’t know exactly 100% what all the chemical reactions of these dust particles are.”The dust on Mars isn’t uniform across the entire planet either, which adds a further issue.
For testing gear for Mars, that involves building a chamber in which the pressure, UV radiation, and atmosphere of the planet can be simulated, along with variations in temperature and potentially recreating the The trouble with trying to re-create Martian dust, however, is that we don’t know exactly what it’s composed of and how it differs across the planet.

So we simulate what it’s like to do a spacewalk similar to what they’d have to do on the lunar surface.
New Spacesuit Unveiled for Starliner Astronauts | NASA “What we’re looking for is degradation. By moving up the date four years, the leisurely pace had to be greatly accelerated. Astronauts will be able to reach across the suit and lift their arms above their heads. But if degradation does occur, the spacesuit team can perform more ground tests to identify the cause, to ensure that spacesuits will continue to function in the Martian environment in the long term.“We’re hoping that one day we can have some kind of display that the crew members can use, especially for working through procedures,” she explained. “But it’s a different kind of an issue. This would be particularly valuable on Mars, where there is a communication delay of at least seven minutes in each direction between there and Earth.Currently, when astronauts are performing complex tasks on a location like the ISS, ground control walks them through each step via audio instructions. But it is dangerous in its own way. “The legs almost act like springs, so you don’t feel the full weight when you’re moving around.”The engineers also find ways to help the astronauts bear the weight, such as using waist straps similar to those found on hiking backpacks, that distribute weight around the hips and shoulders.To test how a suit would feel in the lighter gravity of space environments, NASA uses a system called the “We have big buckets of sand that they get in and out of,” Davis explained. “The only thing we really use the feet and legs for in the ISS environment is for foot restraints at worksites to lock you in place,” Davis explains. We’ll also need a new type of spacesuit.To understand the challenges of building a suit that can withstand the Martian environment and to learn what steps engineers are already taking to address these challenges, we spoke to two NASA engineers about what it takes to make such a spacesuit.Designing a spacesuit is no easy feat, explained Kristine Davis, a spacesuit engineer at NASA’s Johnson Space Center who works on the pressure garment systems team for NASA’s latest spacesuit design, A modern spacesuit consists of a number of components: There is the pressure garment system or PGS, the part a person actually wears including the helmet, and then the portable life support system, which is the backpack of the suit and provides breathable air and other essentials for performing spacewalks. There’s also a team that works on parts like lights and cameras and other auxiliary systems for the suit.Of course, astronauts come in varying shapes and sizes, so a suit can’t be one-size-fits-all.
