SpaceX's New EVA Spacesuits Pass Testing for Historic Commercial Spacewalk

SpaceX has finalized acceptance testing of its new EVA spacesuits, marking a significant milestone for the Polaris Program. The suits will facilitate the first commercial spacewalk, led by entrepreneur Jared Isaacman, aboard SpaceX's Crew Dragon.

SpaceX Completes Testing for Commercial Spacewalk Suits, Paving the Way for Polaris Program's Historic EVA

The acceptance testing of SpaceX's recently developed spacesuits for extravehicular activity (EVA) for the inaugural commercial spacewalk scheduled as part of the Polaris Program has been finalized.

In a recent report by Wccftech, SpaceX manufactures its spacesuits for astronauts to accommodate their requirements within the Crew Dragon spacecraft as part of its NASA missions. These are pressurized spacesuits intended to ensure the crew's safety if their spacecraft experiences a loss of pressurization. On the other hand, SpaceX's new suits for its private astronaut mission will enable astronauts to exit the Crew Dragon and perform their spacewalk.

The Polaris Program has disclosed that SpaceX's EVA spacesuits have completed acceptability testing for their spacewalk. Under the leadership of entrepreneur Jared Isaacman, Polaris intends to engage in the first commercial spacewalk in human history using SpaceX's Crew Dragon. At present, NASA owns the sole spacesuits utilized during EVAs. Polaris's update also includes the initial photographs of the suits in operation, as the space agency's astronauts frequently venture into space to perform maintenance on the ISS.

These spacesuits were tested at NASA's Johnson Space Center in Texas, where the agency also conducted tests on its lunar space suits in December. Axiom Space is developing these suits as part of NASA's increasing dependence on the private sector for its crewed space exploration missions.

Polaris Dawn Mission Aims for Historic Spacewalk and Record-Breaking Altitude

The Polaris Dawn mission has established ambitious objectives, including the Polaris Program's inaugural spacewalk. These include the highest altitude ever reached by astronauts in Earth orbit, a mission apogee of 1,400 kilometers. The ISS's altitude typically restricts missions in Earth orbit, and there needs to be more demand for more ambitious missions.

In late June, the astronauts and SpaceX conducted acceptance tests to assess the systems' capacity to monitor personnel health during a spacewalk. The experiments were conducted in a simulated vacuum, during which the suits were pressurized to ensure the crew's health. SpaceX and the crew evaluated the suits' capacity to regulate the astronauts' body temperature during their spacewalk and pressurization. The personnel also replicated an "elevated metabolic period" during the tests, which was reminiscent of the high-stress environment of a spacewalk.

Two of the four astronauts in the Polaris Dawn mission will engage in a spacewalk. Isaacman and Sarah Gillis, the payload specialist for the mission at SpaceX, will be the individuals in question. Polaris Dawn will be the inaugural spaceflight for Gillis, mission pilot Scott Poteet, and medical officer Anna Menon. Isaacman has already participated in the Inspiration4 mission in 2021, the first purely private orbital spaceflight.

Since the Crew Dragon will be entirely depressurized, all four crew members will be in the space vacuum, despite only two conducting a spacewalk. Before embarking on a spacewalk, astronauts on the International Space Station (ISS) enter a depressurization chamber. However, the Dragon, being a ship, lacks a comparable chamber. Consequently, SpaceX has been compelled to modify the ship to accommodate internal vacuum conditions.
