Elon Musk surprised fans on Instagram by sharing the first official photo of the SpaceX space suit. In the caption, he teased details about the suit, mentioning that it definitely works and was tested to double vacuum pressure. Musk admitted that it was “incredibly hard” to balance the suit’s look and function.

“First picture of SpaceX spacesuit,” Musk wrote on Instagram. “More in days to follow. Worth noting that this actually works (not a mockup). Already tested to double vacuum pressure. Was incredibly hard to balance esthetics and function. Easy to do either separately.”

Though Musk failed to mention the specific purpose of the suit, The Verge suggests they are to be worn by astronauts when riding inside the SpaceX Dragon Capsule. Because they are pressure suits, they are not meant for spacewalks. Rather, the gear is designed for astronauts to wear during transport – just in case the capsule depressurizes. NASA astronauts will also don the suits for the commercial crew program, when SpaceX starts launching people to and from the International Space Station.

The helmet and sleek aesthetic of the suit make it look as if it’s ready to debut in a sci-fi flick. At the same time, it pays homage to “old school” space suits NASA astronauts wore to the moon. Within days, more information on the new SpaceX suit will be revealed.
