Billionaire Jared Isaacman Attempts First Private Spacewalk, Marking New Era for Wealthy Space Enthusiasts
On September 12, 2024, a groundbreaking event in the realm of space exploration took place as tech billionaire Jared Isaacman attempted the first-ever private spacewalk. This historic moment unfolded aboard the SpaceX capsule, dubbed "Resilience," following a launch from Florida that elevated Isaacman and his crew to unprecedented altitudes not reached by humans since NASA's Apollo missions
The Polaris Dawn Mission
The mission, named Polaris Dawn, is the first of three planned ventures funded by Isaacman, who is also the CEO and founder of Shift4, a payments processing company. Isaacman, along with a crew that includes retired Air Force pilot "K" Pet, and SpaceX engineers Anna Menon and Sarah Gillis, aims to explore the potential for private space travel beyond the confines of traditional government programs. Their spacecraft reached an orbit of 870 miles (1,400 kilometers) above Earth, surpassing the heights achieved by astronauts since the Apollo program concluded in the 1970s
Preparing for the Spacewalk
In preparation for the spacewalk, the crew underwent extensive training to ensure their readiness for the challenges of operating outside the spacecraft. The team donned specially designed spacesuits that feature advanced technology, including a heads-up display in the helmet, providing real-time information about the suit's condition. These suits are engineered for comfort and flexibility, allowing them to be worn during launch and landing, thus eliminating the need for separate suits for different phases of the mission
As they prepared to exit the hatch, the crew was subjected to a depressurization process, a critical step that would expose them to the harsh vacuum of space. Isaacman and Gillis were set to alternate their time outside the capsule, each tethered securely to the spacecraft to ensure safety during the two-hour spacewalk. The design of the spacewalk included a support structure resembling a pool ladder, allowing them to maintain contact with the capsule while performing various movements to test the functionality of their suits
The Significance of the Event
This mission marks a significant milestone in the evolution of space tourism, transitioning from mere orbital flights to the more complex and risky endeavor of spacewalking. Historically, spacewalks have been reserved for professional astronauts, with only 263 individuals from 12 countries having completed this feat since the Soviet Union's Alexei Leonov conducted the first spacewalk in 1965. Isaacman's venture into this territory not only highlights the growing capabilities of private spaceflight but also sets a precedent for future commercial missions that may include spacewalks as a standard offering
The Polaris Dawn mission is also notable for its scientific objectives. The crew plans to conduct up to 40 experiments during their time in space, including investigations into the effects of radiation exposure while traversing the Van Allen belt, an area known for elevated radiation levels. This research could provide valuable insights into human health and safety for future long-duration space missions
Challenges and Risks
Despite the excitement surrounding the mission, experts have voiced concerns regarding the risks involved, particularly for a crew composed primarily of individuals without prior spaceflight experience. Dr. Adam Baker, a rocket propulsion expert, emphasized the ambitious goals set by the team and acknowledged the extensive training they underwent to mitigate potential hazards. The mission's success could pave the way for more affordable private-sector space endeavors, expanding access to space for a broader audience
Critics of billionaire-funded space missions have raised questions about the implications of such ventures, particularly when the financier also serves as the mission commander. However, supporters argue that these missions can stimulate economic activity and lead to advancements in space exploration technology. The funds generated from these initiatives can circulate within the economy, supporting jobs and contributing to scientific research
Looking Ahead
As the Polaris Dawn mission progresses, it represents not just a personal achievement for Jared Isaacman but a significant leap forward
