Starship's 10th flight test was scheduled to lift off from SpaceX's Starbase launch site in the Rio Grande Valley of Texas. The company has yet to successfully complete a mission for the the stainless-steel spacecraft, which is being engineered to be fully reusable and would be able to carry up to 100 people to deep space destinations.

After three catastrophic in-flight failures in a row, SpaceX readied a huge Super Heavy-Starship rocket for launch Sunday evening from the Texas Gulf Coast to put a variety of upgrades to the test and to deliberately stress the vehicle to learn more about its capabilities.

SpaceX hoped to launch its Starship Flight 10 test mission on Sunday (Aug. 24) at 7:30 p.m. EDT (2330 GMT), but is now targeting Aug. 25.
