SpaceX Launches a Billionaire To Conduct the First Private Spacewalk

An anonymous reader quotes a report from the Associated Press: A daredevil billionaire rocketed back into orbit Tuesday, aiming to perform the first private spacewalk and venture farther than anyone since NASA's Apollo moonshots. Unlike his previous chartered flight, tech entrepreneur Jared Isaacman shared the cost with SpaceX this time around, which included developing and testing brand new spacesuits to see how they'll hold up in the harsh vacuum. If all goes as planned, it will be the first time private citizens conduct a spacewalk, but they won't venture away from the capsule. Considered one of the riskiest parts of spaceflight, spacewalks have been the sole realm of professional astronauts since the former Soviet Union popped open the hatch in 1965, closely followed by the U.S. Today, they are routinely done at the International Space Station.

Isaacman, along with a pair of SpaceX engineers and a former Air Force Thunderbirds pilot, launched before dawn aboard a SpaceX Falcon 9 rocket from Florida. The spacewalk is scheduled for Thursday, midway through the five-day flight. But first the passengers are shooting for way beyond the International Space Station -- an altitude of 870 miles (1,400 kilometers), which would surpass the Earth-lapping record set during NASA's Project Gemini in 1966. Only the 24 Apollo astronauts who flew to the moon have ventured farther. The plan is to spend 10 hours at that height -- filled with extreme radiation and riddled with debris -- before reducing the oval-shaped orbit by half. Even at this lower 435 miles (700 kilometers), the orbit would eclipse the space station and even the Hubble Space Telescope, the highest shuttle astronauts flew.

All four wore SpaceX's spacewalking suits because the entire Dragon capsule will be depressurized for the two-hour spacewalk, exposing everyone to the dangerous environment. Isaacman and SpaceX's Sarah Gillis will take turns briefly popping out of the hatch. They'll test their white and black-trimmed custom suits by twisting their bodies. Both will always have a hand or foot touching the capsule or attached support structure that resembles the top of a pool ladder. There will be no dangling at the end of their 12-foot (3.6-meter) tethers and no jetpack showboating. Only NASA's suits at the space station come equipped with jetpacks, for emergency use only.
