The sixth flight test of Starship is targeted for 1600 Central Time on Tuesday. SpaceX's next test flight "aims to expand the envelope on ship and booster capabilities and get closer to bringing reuse of the entire system online," the company wrote in a press release, adding, "Objectives include the booster once again returning to the launch site for catch, reigniting a ship Raptor engine while in space, and testing a suite of heatshield experiments and maneuvering changes for ship reentry and descent over the Indian Ocean."
