SpaceX has once again postponed its ambitious Polaris Dawn mission, which aims to achieve a major milestone in space exploration. The mission, scheduled to launch Wednesday morning from NASA's Kennedy Space Center in Florida, has been postponed due to adverse weather conditions and technical problems.
SpaceX announces delay
On Tuesday, SpaceX announced the delay via a post on X, citing adverse weather forecast in Dragon's splashdown areas off the coast of Florida as the main reason for the postponement. The announcement follows a setback earlier in the day, when a helium leak was detected in a line connecting the rocket to the launch tower, forcing the initial launch attempt to be aborted.
Polaris Dawn Mission
The Polaris Dawn mission, led by billionaire entrepreneur Jared Isaacman, was set to fly on a Falcon 9 rocket. The mission's Dragon capsule is planned to reach a maximum altitude of 870 miles (1,400 kilometers), which would exceed any crewed mission in more than fifty years since the Apollo era.
Mission commander Jared Isaacman will lead his four-member team on this historic expedition, which will include the first spacewalk to be performed by private citizens. The team will be equipped with newly developed SpaceX extravehicular activity (EVA) suits designed for the mission. The crew includes:
- Scott PoteetMission pilot and retired US Air Force lieutenant colonel
- Sarah GillisMission specialist and lead space operations engineer at SpaceX
- anna menonMission specialist and medical officer, also principal space operations engineer at SpaceX

The team has undergone extensive preparation for this mission, including more than two years of training, hundreds of hours in simulators, and various other activities such as skydiving, centrifuge training, scuba diving, and climbing an Ecuadorian volcano.
Polaris Program
Polaris Dawn is the first of three planned missions under the Polaris program, a collaboration between Isaacman and SpaceX. Isaacman has not disclosed the exact amount invested in this mission, but it is known that he spent about $200 million for the SpaceX Inspiration4 mission in September 2021, the first all-civil orbital mission.
During the Polaris Dawn mission, the spacecraft will reach its highest altitude on the first day, and will briefly enter the Van Allen radiation belts – a region of high-energy charged particles that pose a potential health hazard if exposed to prolonged exposure.
On the third day of the mission, the crew will use their advanced EVA spacesuits — including head-up displays, helmet cameras and advanced joint mobility systems — for their historic spacewalk. Each astronaut will spend 15 to 20 minutes outside the spacecraft, 435 miles above Earth's surface.
Mission objectives
Mission objectives also include testing laser-based satellite communications between the spacecraft and SpaceX's Starlink constellation, which consists of more than 6,000 satellites aimed at improving the speed of space communications. Additionally, the crew will perform about 40 scientific experiments, including tests with contact lenses equipped with microelectronics to monitor eye pressure and shape.
After a six-day mission, Polaris Dawn is expected to conclude with a landing off the coast of Florida.
