SpaceX’s next Starship flight is off indefinitely after a last-second abort on the pad. The mega rocket came within a few seconds of blasting off Thursday on a test flight from Texas but some of its engines failed to ignite. Without all 33 engines firing, the automatic launch system halted everything. Elon Musk’s company says it will have to figure out what went wrong before making another attempt to send Starship on a space-skimming flight halfway around the world. It was supposed to be the 13th flight for the 407-foot Starship, the world’s biggest and most powerful rocket. NASA is counting on Starship to land its astronauts on the moon in the next few years.
