It’s got a life support system in the back
The life support system, worn like a backpack, will allow for eight-hour spacewalks, which is two hours longer than NASA’s existing spacesuits. The suits feature a rigid upper torso for attaching life support systems and other equipment. Interestingly, astronauts will enter the suit via a hatch on the back, and they don’t need a partner to assist when the time comes to dress up. Axiom chose a fabric for the outer layer that provides “cut resistance, puncture resistance, thermal insulation,” among other features, Ralston said.
