SpaceX Announces Polaris Dawn Mission for Non-Professional Astronauts

SpaceX has announced July 31 as the target date for its upcoming Polaris Dawn mission. The mission, led by billionaire Jared Isaacman, will take four non-professional astronauts to an orbit 435 miles above Earth, surpassing any previous Crew Dragon flight. Additionally, it will feature a historic first commercial spacewalk to test new spacesuits in microgravity. Polaris Dawn aims to study the effects of space radiation on human health and will be the first to test Starlink's laser-based communications in space, crucial for future missions to the moon and Mars. The mission will use SpaceX's Falcon 9 rocket, launching from the Kennedy Space Center in Florida, with the date subject to change.
