SpaceX Polaris Dawn Mission Completes Historic Return

The SpaceX Polaris Dawn mission, which made history with the first spacewalk by non-government astronauts, successfully splashed down off the coast of Florida on September 15. The mission, led by billionaire Jared Isaacman, included a crew of four and reached a peak altitude of 870 miles, the highest since the Apollo missions. During the five-day voyage, Isaacman and SpaceX engineer Sarah Gillis conducted groundbreaking mobility tests outside the Dragon capsule, which notably lacks a pressurized airlock. This mission marks a significant achievement for the commercial space industry and is expected to pave the way for future long-duration missions as part of the Polaris program. The crew's experiences will provide valuable data on space radiation, crucial for planning future lunar and Martian expeditions. NASA chief Bill Nelson hailed the mission as a 'giant leap forward' for private space exploration.
