A tech billionaire popped out from a SpaceX capsule hundreds of miles above Earth and performed the first private spacewalk Thursday (September 12, 2024). a high-risk endeavor once reserved for professional astronauts.

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 a half 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 emerged first, joining a small elite group of spacewalkers who until now had included only professional astronauts from a dozen countries.

“Back at home, we all have a lot of work to do. But from here, it sure looks like a perfect world,” Isaacman said as the capsule soared above the South Pacific. Cameras on board caught his silhouette, waist high at the hatch, with the blue Earth beneath.

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.

Orbit reduced by half

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 (740 km — 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 Gillis to go through the same motions. The SpaceX engineer 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 (3.6-meter) 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. Others 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.

There were a few glitches. Isaacman had to manually pull the hatch open instead of pushing a button on board. Before heading out, Gillis reported seeing bulges in the hatch seal.

Scott “Kidd” Poteet, a former Air Force Thunderbird pilot, and SpaceX engineer Anna Menon stayed strapped to their seats to monitor from inside. All four underwent intensive training before the trip.

It went by “in the blink of an eye,” said SpaceX commentator Kate Tice.

Congratulations streamed in after the spacewalk concluded at one hour and 46 minutes — or a full swing and then some around Earth.

“Today’s success represents a giant leap forward for the commercial space industry,” NASA Administrator Bill Nelson said via X.

Isaacman, 41, CEO and founder of the Shift4 credit card-processing company, has declined to disclose how much he invested in the flight. It was the first of three flights in a program he’s dubbed Polaris; this one was called Polaris Dawn. For SpaceX’s inaugural private flight in 2021, he took up contest winners and a cancer survivor.

Until Thursday, only 263 people had conducted a spacewalk, representing 12 countries. The Soviet Union’s Alexei Leonov kicked it off in 1965, followed a few months later by NASA’s Ed White.

First came space tourism. Now comes an even bigger thrill for the monied masses: spacewalking.

The stage is set for the first private spacewalk Thursday. Tech billionaire Jared Isaacman will pop out of the hatch of his orbiting SpaceX capsule, two days after blasting off from Florida on a chartered flight that lifted him and his crew higher than anyone since NASA’s moonwalkers. He partnered with SpaceX CEO Elon Musk to buy a series of rocket rides and help develop brand new spacesuits.

SpaceX is the first private company to attempt a spacewalk, until now the domain of just 12 countries. There’s a reason why it’s such a niche and elite group: Spacewalking is considered the most dangerous part of any flight after launch and reentry, and demands extensive training.

“Spacewalks are a whole different entire ballgame than just strapping into a rocket and riding it, getting some zero-g time and coming back,” said retired NASA astronaut Chris Cassidy.

Cassidy knows firsthand about the dangers of spacewalking: He was working outside the International Space Station in 2013 when his partner, Italian astronaut Luca Parmitano, almost drowned. Parmitano’s helmet filled with water from his cooling garment, and he barely made it back inside in time. Another 30 minutes that day and “the answer might be different,” Cassidy said.

Cassidy worries there’s “a slippery slope” where the wealthy could try to jump to the front of a spacewalking line with minimal training.

Risk and disaster analyst Ilan Kelman of University College London said it’s “appropriate and inevitable” that non-professionals will end up performing spacewalks. But he anticipates fatalities along the way.

“We can and should do plenty to reduce the risk,” said Kelman. “We must be entirely honest with anyone participating, especially the low chance of rescue when something major goes wrong.”

This spacewalk attempt won’t be like what routinely happens at the International Space Station where astronauts float out to do repairs. Isaacman and SpaceX engineer Sarah Gillis will venture just barely outside the capsule as they soar about 450 miles (more than 700 kilometers) above Earth. Their orbit was initially twice that high, but reduced for the spacewalk.

Besides being new to spacewalking, the crew of four will test suits fresh off the factory floor. All will be exposed to the vacuum of space since the Dragon capsule, unlike larger space vehicles, lacks an airlock.

For Isaacman, throwing away the cabin atmosphere and then restoring it is the riskiest part of the endeavor.

“You can’t afford to get anything wrong along that journey or you sidetrack it,” Isaacman said. “We’re going out just long enough to do what we need to do to get the data.”

The bulk of their training over the past two years has focused on the spacewalk, the highlight of their planned five-day flight. SpaceX put considerable preparation and testing into the capsule and suits, said SpaceX’s Bill Gerstenmaier, a former NASA manager.

For safety, Isaacman and Gillis will always keep a foot or hand on the capsule or the ladder-like support that they’ll position above the hatch. They will be tethered to 12-foot (3.6-meter) lines, but there will be no dangling at the end of them.

The duo will take turns emerging from the hatch, each spending 15 to 20 minutes outside as they flex and test their suits. Their crewmates — SpaceX engineer Anna Menon and former Air Force Thunderbird pilot Scott “Kidd” Poteet — will monitor the spacewalk from inside.

The entire spacewalk should last no more than two hours. Isaacman has refused to say how much he invested in the flight.

To date, 263 individuals representing a dozen countries have performed spacewalks, according to NASA statistics, led by Soviet cosmonaut Alexei Leonov in 1965 with NASA’s Ed White close behind.

China, the only other country to launch its own citizens into space, joined the spacewalking club in 2008. Europe, Japan, Canada and the United Arab Emirates also have seen their astronauts float outside, but always in NASA or Russian garb and under NASA or Russian control.

With SpaceX intent on getting people to the moon and Mars, “we need to start somewhere and the first step is what we’re doing on this mission,” Gillis said.
