SpaceX’s Starship rocket system, the most powerful launch vehicle ever constructed, is set to make its 10th integrated test flight as soon as Sunday evening.

SpaceX was poised to launch another critical test flight of its massive Starship rocket on Sunday, a mission that comes with heightened stakes following a series of explosive setbacks this year.

SpaceX called off Sunday’s launch attempt of the Starship rocket about 15 minutes from launch.
