Beyond the fact that Hollywood costume designer Jose Fernandez was called in to develop its distinctively superhero look, SpaceX hasn’t released a lot of public information about their high-tech spacesuit. But thanks to Japanese astronaut [Soichi Noguchi], Mission Specialist on the first operational Crew Dragon flight and a current occupant of the International Space Station, we now have a guided tour of the futuristic garment. The fact that it was recorded in space is just an added bonus.
As it was released on his personal YouTube account and isn’t an official NASA production, the video is entirely in Japanese, though most of it can be understood from context. You can try turning on the automatic English translations, but unfortunately they seem to be struggling pretty hard on this video. For example as [Soichi] demonstrates the suit’s helmet, the captions read “A cat that is said to have been designed using a 3D printer.” Thanks, Google.
Still, this video provides us with the most information we’ve ever had about how astronauts store, wear, and operate the suit. [Soichi] starts by showing off the personalized bags that the suits are kept in and then explains how the one-piece suit opens on the bottom so the wearer can pull it on over their head. He also points out the three layers the suit is made of: a Teflon-coated outer shell, a fiber-reinforced core for strength, and an inner airtight garment.
Little details are hidden all over the suit, such as a track built into the heel of the boot that’s used to restrain the astronaut’s feet to the Crew Dragon’s seats. [Soichi] also provides what appears to be the first public view of the umbilical connector on the suit. Hidden under a removable cover, the connector features 14-pins for data and power, a wide port for air circulation, and smaller high-pressure port for nitrox that would presumably be used to inflate the suit should the cabin lose pressure while in flight.
It’s taken an incredible amount of work to get commercial spacecraft such as the Dragon to the point that they can begin ferrying crews to the ISS. This close look at all the details that went into something as seemingly mundane as the suit astronauts wear while riding in their craft is a reminder that nothing about human spaceflight is easy.
