Third time was almost the charm. SpaceX’s latest prototype rocket landed in one piece on Wednesday — following two recent test flights that ended in huge explosions. But minutes after cinching the touchdown, the test rocket blew up into a giant fireball. The Starship Serial Number 10, or (SN10), blasted off from Boca Chica, Texas, at around 6:15 p.m., after an earlier flight attempt was aborted earlier in the afternoon. The steel rocket flew as high as 10 kilometers, or about 32,800 feet altitude, before turning to a horizontal “belly flop” position and executing a series of complex mid-air moves. It then came down upright, making a soft landing at around 6:21 p.m.
