Cape Canaveral: SpaceX pushed back the planned test flight of its Starship megarocket on Monday after issues cropped up in the final seconds before liftoff. According to Qatar News Agency, mission controllers paused operations with 40 seconds remaining in the countdown, as engineers worked through technical problems with the Super Heavy booster and the upper-stage Starship spacecraft. The test mission would have been the first Starship launch since a January mission ended eight minutes into flight when Starship, atop a rocket booster, exploded over the Caribbean, sending fiery debris streaking over the Turks and Caicos Islands and prompting a federal probe. SpaceX spokesman Dan Huot said the company could try to launch again at the same time on Tuesday, depending on the issue.
