The US has grounded SpaceX's giant Starship rocket while an investigation is carried out into why it exploded during its latest test flight. The rocket's upper stage dramatically broke up and disintegrated over the Caribbean after launching from Texas on Thursday, forcing airline flights to alter course to avoid falling debris.

SpaceX's seventh Starship test flight will now launch no earlier than Thursday, Jan. 16, at 5 p.m. EST (2200 GMT).
