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."

There's some optimism at SpaceX that the FAA might issue a launch license much sooner, perhaps in time for Starship to fly this weekend. The launch window Sunday opens at 7 am CDT (8 am EDT; 12:00 UTC), about a half-hour before sunrise at SpaceX's Starbase launch site in South Texas.
