Dying SpaceX rocket tears blood-red 'hole' in the sky over Texas — againOn April 10, a bright red atmospheric "hole" was spotted in the night sky above Texas shortly after SpaceX launched 23 Starlink satellites into space. It is the latest example of an increasingly common phenomenon caused by the company's dying rockets.
