Starship is designed to send humans back to the moon and, eventually, take them to the planet Mars. Once SpaceX is given government clearance to launch Starship, it will be used for a Polaris Dawn civilian mission and NASA’s Artemis III human-moon mission.

SpaceX is scheduled to launch its sixth uncrewed test flight of Starship on Tuesday to expand the massive 400-foot rocket's booster capabilities and bring its "catch and reuse" launch system online.
