Jared Isaacman embarks on another space venture nearly three years after his initial journey. He previously made headlines with the Inspiration4 mission, the first all-civilian crew to orbit Earth. Now, in collaboration with SpaceX, his upcoming Polaris Dawn mission aims to push the boundaries even further.
Polaris Dawn seeks to travel beyond any previous SpaceX Dragon capsule mission, venturing through the Van Allen radiation belts for the first time since the Apollo era.
The mission will test new frontiers, with the four-member team planning to conduct the inaugural commercial spacewalk at an altitude of 700 kilometers (around 435 miles) above the planet. This will evaluate Dragon’s compatibility with spacewalks and initiate the use of SpaceX’s EVA suits.
This expedition is more than just a wealthy individual’s space trip; it’s a collaborative project with SpaceX, though financial details remain undisclosed.
Isaacman outlined during a recent press briefing that this mission, alongside two more planned under the Polaris Dawn initiative—including Starship’s first manned flight—are crucial steps towards realizing SpaceX’s goal of interplanetary habitation.
The EVA suits, crucial for constructing permanent habitats on the Moon and Mars, are advanced versions of the suits worn inside the Dragon, featuring several enhancements for spacewalks including thermally insulated boots and a heads-up display.
Significant updates have been made to the Dragon spacecraft to support this mission. Although only two members will exit the Dragon, all four will wear the new EVA suits due to the cabin’s depressurization. Enhancements include improved life support, additional oxygen for the suits, better environmental controls, and a novel nitrogen repressurization mechanism.
Similar to NASA’s ISS protocols, Polaris Dawn astronauts will use umbilical cords attached to their suits for life support during the spacewalk, complemented by added mobility aids around the spacecraft’s hatch. The spacewalk is expected to last between 15 to 20 minutes, within an overall two-hour operation for exiting and re-entering the spacecraft.
Furthermore, the mission will evaluate the performance of Starlink’s laser-based communications in outer space and conduct a series of health-related experiments, especially focusing on the effects of Van Allen belt’s radiation on humans.
“Exploring this area provides significant insights into astronaut health and science, essential for future Mars missions,” Isaacman remarked during his press statement. He is joined by mission pilot Scott “Kidd” Poteet, engineer Sarah Gillis, and medical officer Anna Menon, both of whom are integral SpaceX staff.
Set for launch aboard a Falcon 9 rocket from NASA’s Kennedy Space Center on August 27, Polaris Dawn has a four-hour window starting at 3:38 a.m. EDT. The venture is slated to last up to five days, reaching a peak distance of 1,400 kilometers (870 miles) from Earth, ultimately culminating off Florida’s shoreline.

William Gerstenmaier, a former NASA executive now with SpaceX, encapsulated the mission’s spirit in a press briefing: “It’s time to explore.”
