SpaceX launched Starship on Thursday for a seventh test flight, after weather concerns pushed back an experiment that will feature the spacecraft’s first payload deployment test, and while it successfully caught the Super Heavy Booster, Starship lost connection and “experienced a rapid unscheduled disassembly.”

SpaceX's seventh Starship test flight will now launch no earlier than Thursday, Jan. 16, at 5 p.m. EST (2200 GMT).
