A discarded SpaceX rocket is on a high-speed collision course with the moon

A discarded SpaceX rocket is currently on a high-speed collision course with the moon. After launching a pair of lunar landers more than a year ago, the drifting upper stage is expected to unintentionally slam into the lunar surface this Wednesday. Space tracking experts indicate that this high-speed impact will carve a crater upon arrival. The event follows the rocket's trajectory after completing its primary mission of delivering the landers to their destination last year.
