Billionaires Defy Gravity: What does Jared Isaacman’s First Private Spacewalk mean for us?

The dawn of a new era in space exploration is upon us as billionaire Jared Isaacman prepares to embark on the first-ever private spacewalk. This groundbreaking event is scheduled to take place on Thursday, following Isaacman’s launch aboard a SpaceX capsule from Florida, where he and his crew are set to achieve altitudes higher than any human has reached since the Apollo moon missions.

A Historic Spacewalk

Isaacman, who has previously collaborated with SpaceX for commercial spaceflights, will be joined by SpaceX engineer Sarah Gillis as they step outside their Crew Dragon spacecraft. This mission, part of the Polaris Dawn initiative, marks a significant milestone in private space exploration, as it is the first time non-professional astronauts will attempt a spacewalk, traditionally reserved for government-trained astronauts.

The spacewalk will occur at an altitude of approximately 450 miles (700 kilometers) above Earth, significantly higher than the International Space Station. The duo will spend about 15 to 20 minutes outside the capsule, testing new spacesuits designed for future missions to the Moon and Mars.

The Challenges of Spacewalking

Spacewalking, or extravehicular activity (EVA), is considered one of the most perilous aspects of space travel. Retired NASA astronaut Chris Cassidy, who has firsthand experience with the dangers of spacewalking, expressed concern over the potential risks involved. Cassidy highlighted the need for extensive training, stating, “Spacewalks are a whole different entire ballgame than just strapping into a rocket and riding it.”

The risks are compounded by the fact that the Crew Dragon capsule does not have an airlock, meaning the entire spacecraft must be depressurized for the astronauts to exit. This adds a layer of complexity and danger, as the crew must ensure they maintain contact with the capsule while conducting their tasks.

Safety Measures in Place

To mitigate risks, Isaacman and Gillis will be tethered to the spacecraft with 12-foot (3.6-meter) lines, ensuring they remain connected at all times. They will alternate their turns outside the hatch, with their crewmates—SpaceX engineer Anna Menon and former Air Force pilot Scott “Kidd” Poteet—monitoring from inside the capsule.

Isaacman has emphasized the importance of precision during this mission, stating, “You can’t afford to get anything wrong along that journey or you sidetrack it.” The team has undergone extensive training over the past two years, focusing primarily on the spacewalk, which is the highlight of their planned five-day flight.

The Future of Space Exploration

As private companies like SpaceX continue to push the boundaries of space travel, the Polaris Dawn mission represents a significant step toward making space more accessible to non-professional astronauts. The successful execution of this spacewalk could pave the way for future commercial space missions, where private individuals might engage in activities previously reserved for trained astronauts.

With the Polaris Dawn mission, SpaceX aims to demonstrate the viability of private space exploration and the potential for future missions to the Moon and Mars. As Isaacman and his crew prepare for this historic event, the world watches closely, eager to witness the next chapter in humanity’s journey into the cosmos.
