Tech billionaire does first private space walk

A tech billionaire performed the first private spacewalk hundreds of miles above Earth on Thursday, a high-risk endeavor reserved for professional astronauts — until now.

Tech entrepreneur Jared Isaacman teamed up with SpaceX to test the company’s brand new spacesuits on his chartered flight. The daring feat also saw SpaceX engineer Sarah Gillis going out once Isaacman was safely back inside.

This spacewalk was simple and quick — the hatch was open barely half an hour — compared with the drawn-out affairs conducted by NASA. Astronauts at the International Space Station often need to move across the sprawling complex for repairs, always traveling in pairs and lugging gear. Station spacewalks can last seven to eight hours; this one clocked in at less than two hours.

Isaacman joins a small elite group of spacewalkers who until now had included only professional astronauts from a dozen countries.

The commercial spacewalk was the main focus of the five-day flight financed by Isaacman and Elon Musk’s company, and the culmination of years of development geared toward settling Mars and other planets.

All four on board donned the new spacewalking suits to protect themselves from the harsh vacuum. They launched on Tuesday from Florida, rocketing farther from Earth than anyone since NASA’s moonwalkers. The orbit was reduced by half — to 460 miles — for the spacewalk.

This first spacewalking test involved more stretching than walking. Isaacman kept a hand or foot attached to the capsule the whole time as he flexed his arms and legs to see how the spacesuit held up. The hatch sported a walker-like structure for extra support.

After roughly 10 minutes outside, Isaacman was replaced by SpaceX engineer Sarah Gillis to go through the same motions. Gillis bobbed up and down in weightlessness, no higher than her knees out of the capsule, as she twisted her arms and sent reports back to Mission Control.

Each had 12-foot tethers but did not unfurl them or dangle at the end unlike what happens at the space station, where astronauts routinely float out at a much lower orbit.

More and more wealthy passengers are plunking down huge sums for rides aboard private rockets to experience a few minutes of weightlessness. Other have spent tens of millions to stay in space for days or even weeks. Space experts and risk analysts say it’s inevitable that some will seek the thrill of spacewalking, deemed one of the most dangerous parts of spaceflight after launch and reentry but also the most soul-stirring.

This operation was planned down to the minute with little room for error. Trying out new spacesuits from a spacecraft new to spacewalking added to the risk. So did the fact that the entire capsule was exposed to the vacuum of space.
