Historic Spacewalk: SpaceX’s Polaris Dawn Pioneers Private Astronauts in Orbit
In a groundbreaking moment for space exploration, SpaceX's Polaris Dawn mission is set to achieve an unprecedented milestone: the first-ever spacewalk funded privately. This remarkable venture is spearheaded by billionaire entrepreneur Jared Isaacman, who, along with mission specialist Sarah Gillis, will step outside their Crew Dragon spacecraft for a historic extravehicular activity (EVA). Until now, spacewalks have been the exclusive domain of government astronauts, but today marks a transformative shift as private individuals venture into the void of space.
The Polaris Dawn mission, launched earlier this week from the Kennedy Space Center, represents a new era in space travel. The spacecraft is currently orbiting Earth at an altitude of approximately 700 kilometers (435 miles), and while only Isaacman and Gillis will be venturing outside, the crew consists of four members. The spacewalk is scheduled to commence with Isaacman exiting the spacecraft around 11:30 BST (10:30 GMT; 06:30 ET), followed by Gillis about 18 minutes later. This pioneering event is set to be streamed live, offering viewers a front-row seat to this historic moment.

One of the most significant aspects of this mission is the new spacesuit technology that the crew will be using. The Polaris Dawn astronauts are equipped with advanced extravehicular activity suits that feature cutting-edge materials and design elements borrowed from SpaceX's Falcon and Dragon spacecraft. These suits are designed for enhanced mobility and thermal management, boasting state-of-the-art helmets with integrated heads-up displays and anti-fog visors.
The preparation for the spacewalk involves a meticulous process, including depressurizing the spacecraft and adjusting the cabin environment to match the conditions of space. This step is crucial for ensuring the safety and functionality of the spacesuits, which will be tested during the EVA. The mission is not without its risks; this is the first spacewalk attempted without an airlock, a factor that adds an additional layer of complexity and danger.
The Polaris Dawn mission is also notable for its all-civilian crew. Jared Isaacman, a seasoned pilot and the mission’s financial backer, is no stranger to space travel, having previously funded and participated in the Inspiration4 mission. However, for the other crew members, including Gillis, this will be their first experience in space. Gillis, a former classical violinist turned aerospace engineer, has been instrumental in training SpaceX’s astronaut teams and now brings her expertise to this groundbreaking mission.
This spacewalk not only represents a significant technical achievement but also a symbolic step forward in making space more accessible. With the Polaris Dawn mission, SpaceX is paving the way for future private space endeavors, pushing the boundaries of what is possible and demonstrating that the frontier of space exploration is open to all. As the crew embarks on this historic EVA, they are not just making history—they are also inspiring the next generation of space travelers and explorers.
