The Extravehicular Activity (EVA) Suit

At ~700 km above Earth, the EVA suit will support the Polaris Dawn crew in the vacuum of space during the first-ever commercial astronaut spacewalk. Evolved from the Intravehicular Activity (IVA) suit, the EVA suit provides greater mobility, a state-of-the-art helmet Heads-Up Display (HUD) and camera, new thermal management textiles, and materials borrowed from Falcon’s interstage and Dragon’s trunk. Building a base on the Moon and a city on Mars will require millions of spacesuits. The development of this suit and the execution of the spacewalk will be important steps toward a scalable design for spacesuits on future long-duration missions as life becomes multiplanetary.
