On April 20, SpaceX conducted the first full flight test of its Starship vehicle that is to one day carry astronauts to the moon and perhaps colonists to Mars. The brief flight was a learning experience that ended in the tumbling rocket being ordered to self-destruct, and with a torn-up launch site. On Saturday as early as 8 a.m. Eastern time, the company will attempt a second test flight from its launch site in Boca Chica, Texas. The launch had been planned for Friday but was postponed one day to replace a part on the rocket.
