SpaceX is targeting May 19 for the debut launch of Starship V3, the first flight of the rocket’s newest version and the 12th Starship mission overall. The launch window opens at 6:30 p.m. EDT and runs for 90 minutes, with the vehicle set to lift off from SpaceX’s Starbase site in South Texas.
The flight matters because SpaceX says Starship V3 is a bigger and more capable vehicle than the versions that came before it. It will also be the maiden launch from Starbase’s Pad 2, marking a new step in the company’s effort to move the giant rocket toward regular use.
SpaceX announced on May 12 that it was aiming for the May 19 debut, giving the program a fixed date after months of work on the next iteration of the system. Starship is described as the biggest and most powerful rocket ever built, and V3 is the latest attempt to make that platform more practical for future missions.
The changes run through both stages. On the Super Heavy booster, SpaceX has moved from the original four grid fins to three, each one 50% larger and significantly stronger, according to the company. The hot stage that joins the booster to the Ship upper stage is now integrated into Super Heavy and will not be discarded during flight. SpaceX also says the booster’s fuel transfer tube has been completely redesigned and is now roughly the size of a Falcon 9 first stage, a change that is meant to allow all 33 engines to start up simultaneously and support faster, more reliable flip maneuvers.
Ship has been reworked from the ground up as well. SpaceX says the propulsion system was redesigned on a clean-sheet basis, with updates that increase propellant tank volume and improve the reaction control system used for steering in flight. The new upper stage also includes propellant feed connections designed to support off-Earth fuel transfer, a capability central to deep-space missions. The vehicle is powered by the V3 Raptor.
That is the tension inside this launch: SpaceX is not just trying to send up another test article. It is trying to prove that a larger, more capable Starship can begin to behave like a system built for repeatable operations, even as the company keeps changing the hardware underneath it. If the flight proceeds as planned, May 19 will not just be another Starship test. It will be the first public run of the rocket SpaceX says it wants to take farther, carry more with and eventually use in space beyond Earth.
