SpaceX crews are preparing for the 10th flight test of its Starship spacecraft and Super Heavy rocket. The launch is currently set for 7:30 p.m. on Tuesday from SpaceX’s Starbase launch facility in Texas.

The launch from Starbase in southern Texas was called off with just 40 seconds on the clock. The clock had been held at 40 seconds due to an anvil cloud in the area that had to clear in a certain timeframe. Having failed to move far enough away from the site, SpaceX scrubbed what would have been the Starship rocket’s 10th test flight.
