Update: SpaceX delayed the mission by 24 hours. For the latest information, read this story. For the first time in nearly three months, SpaceX is about to conduct a Starship rocket launch.

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

SpaceX officials scrubbed the launch of the proposed 10th test flight of Starship/Super Heavy, which was slated to lift off from the company’s Starbase headquarters in the Rio Grande Valley on Sunday evening.
