Elon Musk’s SpaceX and the Federal Aviation Administration are in a standoff over when the space company’s next Starship mega-rocket will blast off from South Texas.

The Federal Aviation Administration could approve a license for the launch of SpaceX's Starship 5 as soon as this month, a source told Reuters on Tuesday. Last month, the FAA said it did not expect a determination on a license before late November.

SpaceX is targeting as soon as Oct. 13 for the next launch of its Starship Super Heavy megarocket, but it all hinges on approval from the FAA, which says to expect the flight in "late November."
