SpaceX Delays Historic Polaris Dawn Mission Due to Helium Leak

The mission aims to achieve the first-ever commercial spacewalk and reach the highest Earth orbit since Apollo.

The launch, initially scheduled for Tuesday, was postponed after a ground-side helium leak was detected.
Polaris Dawn's crew includes billionaire Jared Isaacman and SpaceX engineers Anna Menon and Sarah Gillis.
The mission will test new SpaceX spacesuits and conduct over 30 scientific experiments.
Crew members will attempt the first commercial spacewalk at an altitude of 435 miles.
The mission will also test Starlink's laser-based satellite communications.
