SpaceX founder and CEO Elon Musk shared the "first picture" of one of his company's spacesuits Wednesday morning on Instagram.
"Worth noting that this actually works (not a mockup)," Musk wrote. "Already tested to double vacuum pressure. Was incredibly hard to balance esthetics and function. Easy to do either separately."
Musk promised "More in days to follow."
Musk’s photo generated 181,225 likes and counting Wednesday about four hours after he posted it.
The Verge reported that the SpaceX suites are meant to be worn by astronauts traveling inside the company’s Dragon Capsule.
The outfits are pressure suits, according to The Verge, meaning astronauts were them during transport as a safeguard against depressurization in the capsule.
The suits are reportedly not meant for spacewalks, however, but will be worn by National Aeronautics and Space Administration (NASA) astronauts in the future.
NASA astronauts will don the suits for the commercial crew program when SpaceX eventually begins ferrying people to and from the International Space Station (ISS).
Boeing, meanwhile, in January unveiled blue space suits astronauts will someday wear during missions on its CST-100 Starliner.
The Starliner is Boeing’s capsule for moving people on and off the ISS, and the suits for the vessel were first displayed at its facility at NASA’s Kennedy Center in Florida.
David Clark Company reportedly designed the outfits for Boeing, which are not meant for spacewalks.
The suits are also not built for withstanding impacts from micrometeoroid objects, and they lack the layers necessary for shielding people from wide thermal changes in space.
The designs Musk revealed Wednesday resemble rumored designs for SpaceX suits that appeared on Reddit over a year ago.
Musk once served as CEO of PayPal before selling it to eBay in 2002 for $1.5 billion and has since focused much of his energy on space exploration.
The entrepreneur founded SpaceX in 2002 and has long voiced hopes about reaching Mars and beyond.
SpaceX has reportedly received a significant portion of its rocket development funding from NASA by taking contracts from it to transport cargo on and off the ISS.
