The other suit, in a bright orange fabric, is to be worn by astronauts during launch and re-entry back to Earth while they are sitting inside the Orion crew capsule, the spacecraft for deep-space travel that NASA has been working on for 15 years. The suit provides protection and oxygen to the astronauts in case of an accident that causes the capsule to become depressurized. It is designed to keep astronauts alive for six days.

“The primary use in the case of an accidental depressurization,” said Dustin Gohmert, a spacesuit engineer who modeled the Orion suit. “We can take safe haven in this suit. We’ll seek refuge in here.”

Each outfit shared similarities with its utilitarian predecessors worn by earlier astronauts. Spacesuits being designed elsewhere have more futuristic and fashionable appearances.

SpaceX, which has a contract to fly astronauts to the International Space Station in the near future, sent a mannequin wearing its suit to orbit in March. It featured a 3D-printed helmet and a black and white design that seemed to take inspiration from motorcycle racing suits.

Boeing, whose Starliner will also travel to the station, debuted its blue, zippered suit in 2017. It is about 10 pounds lighter than what astronauts wore on the space shuttle.
