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.

The postponed launch delays SpaceX's attempt to achieve several long-sought development milestones missed due to past tests ending in early failures.
