The Polaris Dawn crew were aiming to test SpaceX’s newly developed Extravehicular Activity (EVA) spacesuits, which were customised by a costume designer who’s worked on some big superhero films.
Even though only two of the crew actually went out into space to perform a spacewalk, all of the team had to be suited up in their brand new EVA gear.
This is because the spacecraft’s hatch had to remain open during the spacewalk, exposing all four crew members to the vacuum of space.
This was all part of the mission, and after the spacewalks, SpaceX reported that everything went to plan and all the people on board were safe and sound.
