Photos: Falcon takes flight

A steel tube built as a stand-in for the core stage of NASA’s Space Launch System has arrived at the Kennedy Space Center for a series of rehearsals to hone the skills of technicians before the real rocket reaches the spaceport, an oft-delayed milestone that could still be a year or more away.

The Tranche 1 Transporter Layer A mission is the fourth flight supporting the Space Development Agency’s Proliferated Warfighter Space Architecture constellation. The next launch attempt could come as soon as Saturday.

SpaceX is gearing up for the next big leap in the development of the next-generation Starship heavy-lift launch vehicle with a test flight to more than 40,000 feet over the Texas Gulf Coast as soon as Tuesday.
