\"SpaceX<\/p>\n

<\/strong>SpaceX<\/strong> unveiled the Extravehicular Activity (EVA) suit<\/strong> that the Polaris Dawn crew will wear during their mission. Approximately 700 km above Earth, the SpaceX 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\u2019s interstage and Dragon\u2019s trunk.<\/p>\n

All of these enhancements to the EVA suit are part of a scalable design, allowing teams to produce and scale to different body types as SpaceX seeks to create greater accessibility to space for all of humanity. 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 multi-planetary.<\/p>\n

Polaris Dawn, the first of the program\u2019s three human spaceflight missions, is targeted to launch to orbit no earlier than the summer of 2024. During the five-day mission, the crew will perform SpaceX\u2019s first-ever Extravehicular Activity (EVA or spacewalk) from Dragon, which will also be the first-ever commercial astronaut spacewalk. This historic milestone will also be the first time four astronauts will be exposed to the vacuum of space at the same time.<\/p>\n

Supporting the crew throughout the spacewalk will be SpaceX\u2019s newly-developed EVA suit, an evolution of the Intravehicular Activity (IVA) suit crews currently wear aboard Dragon human spaceflight missions. Developed with mobility in mind, SpaceX teams incorporated new materials, fabrication processes, and novel joint designs to provide greater flexibility to astronauts in pressurized scenarios while retaining comfort for unpressurized scenarios. The 3D-printed helmet incorporates a new visor to reduce glare during the EVA in addition to the new Heads-Up Display (HUD) and camera that provide information on the suit\u2019s pressure, temperature, and relative humidity. The suit also incorporates enhancements for reliability and redundancy during a spacewalk, adding seals and pressure valves to help ensure the suit remains pressurized and the crew remains safe.<\/p>\n

All of these enhancements to the EVA suit are part of a scalable design, allowing teams to produce and scale to different body types as SpaceX seeks to create greater accessibility to space for all of humanity. While Polaris Dawn will be the first time the SpaceX EVA suit is used in low-Earth orbit, the suit\u2019s ultimate destiny lies much farther from our home planet. Building a base on the Moon and a city on Mars will require the development of a scalable design for the millions of spacesuits required to help make life multi-planetary.<\/p>\n
