The Z-1 should be ready for liftoff on its first mission sometime in 2015.įollow Miriam Kramer on Twitter or. By understanding exactly what a suit should protect against in certain environments and then designing the prototype around those, Ross said, NASA should have the capability to produce a suit specifically tailored for any mission. If an astronaut is sent to an asteroid or Mars, the engineers wanted to be sure that the spacewalker is protected from background radiation while still able to move around the planet's surface.īut that doesn't mean that developers won't want to use this research to specialize the suit eventually. NASA aimed to design the Z-1 around the most challenging aspects of any mission astronauts might be faced with. "It sounds very heavy," Ross says, "but once you inflate the suit, it does help to support itself." By having the astronauts perform "geology duties" (collecting rocks, bending down to pick up material, etc.), the suit's designers saw how the prototype performed by comparison to the EMU in use today. To gauge the way the spacesuit might perform in space, NASA's engineers took their testing to the desert. Even on Mars - where the gravity is one-third that of Earth's - those extra 58 pounds might make a significant difference. Current suit models weigh around 100 pounds (45 kilograms), but the Z-1 clocks in at an unwieldy 158 pounds (72 kg). The new prototype is extremely flexible, but a bit heavy.

The new backpack model is more efficient and less susceptible to contaminants.Īlthough the Z-1 and the PLSS 2.0 aren't ready to be joined into one prototype yet, eventually they could combine to create an even more efficient space-traversing suit. The backpack model in use today is sensitive to contamination and quickly uses up oxygen, making it difficult for astronauts to conduct long spacewalks. NASA is in the process of crafting a new life-support backpack - known as the PLSS 2.0 - for the suit as well. "We think it's less prone to injury," Ross says, "especially shoulder injury which can occur with the shuttle EMU-donning method." The suit hooks up to the outside of the spacecraft using the "space port" opening, and the spacewalker simply climbs in and detaches. By using a rear-entry design, the astronauts won't need to go through an airlock at all. Using airlocks to depressurize is a time consuming, exhausting process. Whereas with this suit, the subject crawls in through the back, and then we just shut the door."Ĭreating a back-entry suit solves a few of the problems spacewalkers often face during trips to the International Space Station. "So the shuttle EMU splits at the waist and you put pants on and you put the top on separately and they connect in the middle. "One of the big differences is the rear-entry design," Amy Ross, one of the engineers responsible for the suit's development, said during a NASA video interview. The Z-1 spacesuit will potentially be used to explore different planets.
