A crew of four secret astronauts made account in the former hours of Thursday when they open up the hatching of their SpaceX Dragon capsule and conducted the first commercial spacewalk .
The spacewalk , the bad part of the five - dayPolaris Dawnmission , kicked off at 6:12 a.m. ET when O pop out run into the astronauts ’ spacesuit . Only two of the four crew members really go the vehicle , but all four had to assume the unexampled SpaceX - made suits because the Dragon space capsule does n’t have an airlock . That mean the entire ballistic capsule had to be depressurized .
A spacewalk — sometimes called extravehicular bodily function — is when astronauts leave the comparative safety of their space vehicle for the vacuum of space . In the history of human space travel , spacewalks have only ever been performed by government activity cosmonaut , who use them as an opportunity to do haunt , do maintenance , or to conduct scientific experiments . Spacewalks performed by NASA astronauts typically last between five and eight hour .
Billionaire enterpriser and mission leader Jared Isaacman was the first to exit the Dragon capsule ; after he return , SpaceX railroad engineer Sarah Gillis took a turn in the vacuum of place . They used a particular ladder mobility aid dubbed a “ skywalker , ” which SpaceX added to the Dragon just for this function , to attend them outside the ejector seat . The pair was connected to the spacecraft by umbilical electric cord and they kept contact with the run at all sentence . The spacewalk was very quick , with each mortal outside the ballistic capsule for less than ten minutes . During that clock time , Isaacman and Gillis perform a serial of apparent motion to test the suits ’ mobility and performance .
“ Back at house , we all have a lot of body of work to do , but from here — look like a perfect reality , ” Isaacman tell .

SpaceX ’s spacesuits are noticeably lighter than the hulking white suits tire out by NASA astronauts , and the fellowship articulate they were designed with “ mobility in brain . ”
One of the biggest difference between NASA spacesuit and the ones designed by SpaceX is the lack of the bulky ashen haversack , called a Primary Life Support System . or else of a rucksack , the major life support system are supplied through the 12 - invertebrate foot umbilical electric cord that ’s connected to the spacecraft .

While the pair take their bit outside the cunning , the remaining crewmates , former U.S. Air Force airplane pilot Scott “ Kidd ” Poteet and SpaceX engineer Anna Menon , monitored their forward motion carefully . After Gillis closed the crosshatch , the spacecraft was gradually repressurized . The entire operation take up less than two hours .
This remarkable achievement is a vast boon for SpaceX ’s private spacefaring aspiration , which most famously admit a individual crewed mission to Mars . If SpaceX can pull it off , the suits wear by humans move to the Red Planet will likely have their origins in the spacesuit worn by Isaacman and his crewmates on Polaris Dawn .
“ While Polaris Dawn will be the first prison term the SpaceX EVA suit is used in low-down - Earth orbit , the suit ’s ultimate destiny lies much far from our home planet , ” the companionship said back in May . “ build a base on the Moon and a city on Mars will ask the development of a scalable design for the millions of spacesuits required to help make life story multi - wandering . ”
This is n’t the first milestone in the Polaris Dawn missionary work . After abstract off former Tuesday morningon a SpaceX Falcon 9 rocket engine , the capsule dismiss its thruster to impel the crew to a in high spirits point of 1,400 kilometers ( 870 land mile ) — high than any humans have traveled since the Apollo 17 mission to the moonlight in 1972 .
Now that the two major milestones are behind them , the Polaris Dawn bunch will spend their remain days in celestial orbit conducting a slew of science experiments and go on examination of optical maser communications between the capsule and Starlink net satellite . The crew will likely return in the other hours of Sunday and splash down off the coast of Florida , though SpaceX has not yet released a firm schedule for the arrival back on Earth .
