Revolutionizing the Cosmos: SpaceX’s Historic Private Spacewalk Breaks New Ground in Exploration

Two private astronauts emerged from their spacecraft early Thursday morning, performing the first commercial spacewalk in history. The spacewalk was the centerpiece of Polaris Dawn, a collaboration between Elon Musk‘s SpaceX and Jared Isaacman, a billionaire entrepreneur who is leading the mission.

“Back home, we all have a lot of work to do, but from here, Earth looks like a perfect world,” he said, standing in the hatch of SpaceX’s Crew Dragon capsule with the planet overhead.

The operation’s success further reinforces the fact that space travel is no longer the exclusive province of professional astronauts working for government space agencies like NASA — and now neither are daredevil spacewalks, in which astronauts are protected only by their spacesuits from airless doom. The Polaris missions, the first of three, are intended to accelerate the technological advances needed to realize Musk’s hope of one day sending people to Mars.

NASA Administrator Bill Nelson applauded the spacewalk, in which the government space agency played virtually no role.

“Today’s success represents a giant leap forward for the commercial space industry and NASA’s long-term goal of building a vibrant U.S. space economy,” Nelson wrote on the X website.

The spacewalk officially began at 6:12 a.m. Eastern Standard Time, with oxygen being pumped into the astronauts’ spacesuits. It was nearly three hours later than planned, but the operation went off without a hitch.

Since SpaceX’s Crew Dragon spacecraft has no airlock, the only way to perform a spacewalk is to let all the air out of the craft. NASA and Soviet astronauts performed similar spacewalks in the 1960s.

First turning a crank, Isaacman opened the capsule’s top hatch and stepped outside, where he performed mobility tests on his spacesuit.

For a trip that had previously reached the highest orbit undertaken by humans in more than half a century, its stay in the vacuum of space was brief: After a few minutes, Isaacman re-entered the capsule, and another crew member, SpaceX engineer Sarah Gillis, moved outside and performed the same mobility tests.

Although the other two crew members, Scott Poteet and Anna Menon, remained inside the vehicle, they also wore spacesuits inside the airless capsule. It was the first time that four astronauts had been exposed to the vacuum of space simultaneously.

After re-entry, Gillis closed the hatch and the interior of the spacecraft slowly repressurized. Less than two hours after it began, the spacewalk was over.

A key goal of the Polaris Dawn mission is the development of more advanced spacesuits, which would be necessary for any attempt at extraterrestrial colonization by SpaceX. During a press briefing before the launch, Isaacman mused about how someone stepping foot on Mars might one day wear a future version of the spacesuit developed by SpaceX for this mission.

“It is a great honor to have the opportunity to test it on this flight,” he said.

Closer to Earth, commercial spacewalks could open up other possibilities previously unimaginable, such as technicians repairing private satellites in orbit. Isaacman has even suggested that the second Polaris mission could attempt a trip to NASA’s aging Hubble Space Telescope to make repairs and extend its life in orbit.

Isaacman and Gillis’ spacewalks were short and modest in complexity. Unlike the frenetic scenes in science fiction movies, they waited patiently as they slowly evacuated the air from their capsule. Then they moved methodically, following a carefully planned choreography that lasted only a few minutes.

After manually opening the hatch, Isaacman propelled himself upward using a handrail mounted on the top of the Crew Dragon capsule. At no point did the ship let go of him as he performed a series of movements to test the capabilities of the spacesuits.

When his time was up, he climbed back down into the Crew Dragon capsule and Gillis repeated the same actions.

The Polaris Dawn crew’s caution was a reminder that space is an inhospitable and dangerous environment, and that during spacewalks astronauts are enclosed in a small bubble of air — spacesuits — that prevents them from suffocating in the vacuum of space.

Although there have been near-misses for astronauts, such as the first spacewalk by a Soviet astronaut in 1965, exiting a spacecraft is not the most dangerous part of spaceflight. No astronaut has ever been killed or seriously injured during a spacewalk. And spacewalks are not uncommon: More than 270 spacewalks have been conducted on the International Space Station since December 1998, most of them without incident. (Astronauts on the International Space Station enter and exit through airlocks, which minimize the amount of air released into space.)

Deaths in spaceflight have occurred during launches, as was the case with the loss of the space shuttle Challenger and its crew in 1986, or during landings, as when the space shuttle Columbia burned up in the scorching heat of reentry through Earth’s atmosphere in 2003.

The Polaris Dawn mission has so far been going smoothly.

A SpaceX Falcon 9 rocket launched the Crew Dragon capsule and four astronauts early Tuesday morning into an elliptical orbit that, at its highest point, was 750 miles (1,215 kilometers) above the Earth’s surface.

This is the farthest orbit from the planet since NASA’s Apollo lunar missions in the 1970s.

At that altitude, they passed through the South Atlantic Anomaly, a weak spot in Earth’s magnetic field that allows high-energy charged particles from regions known as the Van Allen belts to approach Earth’s surface. Much of the spaceflight’s radiation dose — equivalent to several months on the space station — occurred during these early orbits.

Late Tuesday, the thrusters fired to stretch its orbit to a high point of about 1,400 kilometers (850 miles), surpassing the altitude of 1,372 kilometers (840 miles) that two NASA astronauts, Pete Conrad and Richard Gordon, reached during the Gemini XI mission in 1966, which had been the record distance for astronauts on a space flight not headed to the moon.

After orbiting the Earth six times in high orbit, Crew Dragon returned to a lower orbit where there is less danger from radiation and micrometeoroids.

During their spaceflight, the four crew members are conducting about 40 experiments, mostly to investigate how weightlessness and radiation affect the human body. They have also tested laser communications between Crew Dragon and SpaceX’s Starlink constellation of internet satellites.

Historic Commercial Spacewalk Marks New Era in Space Travel

In a groundbreaking achievement, two private astronauts, Jared Isaacman and Sarah Gillis, performed the first-ever commercial spacewalk on Thursday morning, marking a significant milestone in the history of space travel. The spacewalk was part of the Polaris Dawn mission, a collaborative effort between Elon Musk’s SpaceX and billionaire entrepreneur Jared Isaacman.

A New Frontier in Space Exploration

As Isaacman stepped out of the SpaceX Crew Dragon capsule, he gazed at the Earth below, remarking, “Back home, we all have a lot of work to do, but from here, Earth looks like a perfect world.” This historic moment signals a shift in the space industry, where space travel is no longer the exclusive domain of professional astronauts working for government agencies like NASA. The Polaris missions aim to accelerate technological advancements necessary for Elon Musk’s ambitious goal of sending humans to Mars.

NASA Administrator’s Praise

NASA Administrator Bill Nelson applauded the spacewalk, stating, “Today’s success represents a giant leap forward for the commercial space industry and NASA’s long-term goal of building a vibrant U.S. space economy.” The government space agency played a minimal role in the operation, highlighting the growing significance of private endeavors in space exploration.

The Spacewalk

The spacewalk officially began at 6:12 a.m. Eastern Standard Time, with oxygen being pumped into the astronauts’ spacesuits. Although delayed by nearly three hours, the operation proceeded without a hitch. Since the Crew Dragon spacecraft lacks an airlock, the only way to perform a spacewalk was to depressurize the craft, a technique reminiscent of NASA and Soviet astronauts’ spacewalks in the 1960s.

Isaacman and Gillis conducted mobility tests on their spacesuits, with Isaacman re-entering the capsule after a few minutes and Gillis performing the same tests. The other two crew members, Scott Poteet and Anna Menon, remained inside the vehicle, wearing spacesuits in the airless capsule. This marked the first time four astronauts were exposed to the vacuum of space simultaneously.

Advancements in Spacesuit Technology

A key objective of the Polaris Dawn mission is the development of more advanced spacesuits, essential for any future extraterrestrial colonization efforts by SpaceX. During a pre-launch press briefing, Isaacman envisioned someone wearing a future version of the spacesuit on Mars. “It is a great honor to have the opportunity to test it on this flight,” he said.

Implications and Possibilities

The success of commercial spacewalks could open up new possibilities, such as technicians repairing private satellites in orbit. Isaacman has even suggested that the second Polaris mission might attempt to repair and extend the life of NASA’s aging Hubble Space
