First picture of SpaceX spacesuit. 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. A post shared by Elon Musk (@elonmusk) on Aug 23, 2017 at 12:59am PDT

The SpaceX spacesuit's already been tested to double vacuum pressure, according to Musk. And, we're assuming it passed those trials, along with the ocean landing mobility and safety runs. By far its most striking feature is its slim, fitted design. Most contemporary, and even next-gen spacesuits, look bulky and utilitarian. The SpaceX spacesuit, on the other hand, looks a lot lighter. Which makes sense, seeing as it was crafted by a Hollywood costume designer, renowned for making Batman and Wolverine's figure-hugging outfits.

The helmet also seems to offer plenty of visibility, although less so than NASA's future Z-2 suit. Musk claims it was "hard to balance" aesthetic with functionality. For the most part, the design seems to keep things simple. There are minimal grey lines and patches that sit nicely alongside its traditional white coloring. Its closest comparisons in the world of cinema are probably the suits worn in Interstellar, and (appropriately) The Martian.

Musk is keen to milk this unveiling for all it's worth, so expect more shots over the coming days. The suit may eventually be worn by astronauts on NASA's commercial crew program.
