SpaceX could launch Starship's fifth test flight as early as this Sunday if the FAA passes the needed licenses.

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.

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."
