SpaceX delayed the Starship rocket test flight due to an unspecified issue. The launch, aimed at furthering Mars colonization, was to occur from Texas. A reschedule is expected within 24 hours. The rocket requires improvements for reliability and safety before future crewed missions.

Starship could launch around 6:30 p.m. EST Monday from Starbase in South Texas, according to SpaceX, which will livestream the flight test.

Starship had been expected to launch again Monday. A previous launch ended in an explosion over the Caribbean, and sent commercial airlines scattering to avoid falling rocket debris.
