Starship SN15 will also have to undergo a static fire test during, which the rocket’s three Raptor engines will briefly fire while the SN15 is tethered to the ground.
The rocket will not be cleared for flight until these tests are completed to a satisfactory degree.
Eagle-eyed SpaceX fans have also noticed a Starlink satellite was mounted on the spacecraft and documents filed with the US Federal Communications Commission (FCC) suggest SN15 will not launch before April 20.
SpaceX has filed a request to test a Starlink terminal around Boca Chica while in flight.
The request reads: “The authority requested herein will be sharply limited in duration: SpaceX requests to operate under this STA for a period of only 60 days, beginning on April 20, 2020, or the date on which the STA requested herein is granted, whichever is later.
