SpaceX’s Polaris Dawn spacecraft prepares for historic spacewalk, and Commander Jared Isaacman shares his thoughts on the mission

SpaceX is preparing for a landmark private space mission, scheduled to launch later this month. The mission, called Polaris Dawn, is set to mark SpaceX’s maiden venture into crewed spaceflight beyond the orbit of the International Space Station.

The Coming of Polaris Dawn

Led by Polaris program founder Jared Isaacman, the mission is scheduled to lift off from Florida shortly before dawn on Aug. 26. “The timing of it being so close to dawn is pretty symbolic for what we’re trying to accomplish with this mission,” Isaacman shared with CNBC’s Investing in Space.

Isaacman, who previously commanded the Inspiration4 mission, will lead a crew of four, including Scott Poteet as pilot and SpaceX staffers Anna Menon and Sarah Gillis in roles critical to the mission’s success.

Mission Objectives and Challenges

The Polaris Dawn crew plans a multi-day orbit with no specific destination, aiming to reach altitudes not reached by humans in more than half a century. “Our goal is to go farther into space, reaching altitudes that have not been reached by astronauts in decades,” Isaacman said.

The highlight: a pioneering spacewalk

The mission’s highlight is the planned spacewalk, a first for any private spaceflight company. “The spacewalk is a profound challenge, similar to being surrounded by the vacuum of space,” Isaacman said, noting the extensive preparation and risks involved.

Mission details and preparation

Over the course of five days, the Polaris Dawn crew will engage in a variety of activities, including science experiments and preparation for the groundbreaking extravehicular activity (EVA). “Our first day will be critical to ensuring the spacecraft is clear of orbital debris and operating as intended,” Isaacman noted.

While navigating areas such as the South Atlantic Anomaly, the crew will be exposed to significant radiation, equivalent to three months aboard the ISS, underscoring the risks and scientific value of the mission.

The Spacewalk and Beyond

The spacewalk, scheduled for day three, will see Isaacman and Gillis venture outside the spacecraft, testing out SpaceX’s new EVA suits. “This spacewalk is not just an outside adventure; it’s a test of our equipment and our ability to function in the harsh environment of space,” Isaacman said.

Innovation in spacesuit design

SpaceX developed these new EVA suits based on their standard IVA suits, which are typically used inside spaceships. “We’ve done extensive testing to ensure these suits can withstand the unique conditions of space,” Isaacman said.

The Wider Impact of Polaris Dawn

Isaacman hopes Polaris Dawn will inspire further interest and development in private space exploration. “We are pushing the boundaries to inspire future generations and pave the way for more advanced missions,” he concluded.

As the launch date for Polaris Dawn approaches, the space community is watching with bated breath, ready to witness new milestones in human spaceflight.
