ORLANDO, Fla. — SpaceX has unveiled long-awaited spacesuits intended for spacewalks that will first be used on an upcoming private spaceflight.
The company revealed the design of the extravehicular activity (EVA) suit on its website and social media May 4. The suit is based on the current pressure suits worn by astronauts on Crew Dragon flights but, unlike those suits, is intended for use on spacewalks.
The suit upgrades include new joint designs that remain soft until pressurized while maintaining mobility, improved thermal management, and an upgraded helmet with an exterior coating that acts like a sun visor along with a camera and heads-up display that provides information on the status of the suit during the spacewalk. Umbilicals provide life support for the suits.
The suits will first be worn on the Polaris Dawn mission, a Crew Dragon private spaceflight that is part of the Polaris program of missions backed by billionaire Jared Isaacman. He will fly on that mission with Kidd Poteet, Sarah Gillis and Anna Menon. All four will wear the suits because Crew Dragon, lacking an airlock, will have to be depressurized for the spacewalk.
Gillis said in a discussion hosted by SpaceX on social media May 4 that the spacewalk would last about two hours, including the time depressurizing the cabin at the start and repressurizing it at the end. Two people will exit the capsule, using a device called a “skywalker” at the front hatch with handholds and interfaces to assist them in going through the hatch.
The spacewalkers will go through a “test matrix” to collect data on the performance of the EVA suits. “This is looking at mobility, movement in this microgravity environment, how the suit is performing,” she said. “There’s a whole series of test questions that will be stepped through for the time outside the spacecraft.”
The suits have been extensively tested on the ground, including a test where the entire Crew Dragon capsule…
