The upgraded Version 3 (V3) Starship was assembled on the launch pad after SpaceX completed a series of final inspections and prelaunch tests on both the Super Heavy booster and Ship upper stage.
The mission is scheduled to launch no earlier than 6:30 p.m. EDT on 21 May.
Starship V3 Debuts On Flight 12
The new-generation Starship V3 includes the Super Heavy booster paired with the Ship upper stage, together forming the largest and tallest rocket system ever constructed.
The two stages were stacked at SpaceX’s newly developed launch facility at Starbase, marking another major milestone in the company’s rapid Starship development programme.
SpaceX had temporarily separated the stages in recent days while conducting additional prelaunch testing and systems checks.
Super Heavy Booster Completes Engine Tests
The Super Heavy booster recently underwent multiple evaluations, including test firings of its 33 Raptor 3 engines.
The upgraded Raptor engines are expected to provide greater efficiency, performance and reliability as SpaceX continues refining Starship for future orbital and deep-space missions.
The company has been accelerating testing activity ahead of the Flight 12 launch window.
Flight 12 Will Follow Suborbital Profile
Starship Flight 12 is planned as a suborbital mission rather than a full orbital flight.
Under the current mission profile, the Ship upper stage is expected to perform a controlled splashdown in the Indian Ocean, while the Super Heavy booster will target a soft landing in the Gulf of Mexico.
Unlike some previous tests, SpaceX will not attempt a return-to-launch-site recovery during this mission.
SpaceX Continues Pursuing Full Reusability
Starship has been designed as a fully reusable launch system intended to dramatically lower the cost of spaceflight.
SpaceX has already successfully recovered Super Heavy boosters using the launch tower’s mechanical “chopstick” arms to catch the returning booster midair.
However, the company has not yet attempted a similar recovery for the Ship upper stage.
Industry observers say successful performance during Flight 12 could potentially pave the way for a Ship catch attempt during Flight 13 or Flight 14.
Starship Central To Future SpaceX Missions
Starship remains central to SpaceX’s long-term plans for lunar exploration, Mars missions, satellite deployment and future commercial space transportation.
NASA also plans to use a modified version of Starship as part of the Artemis programme for future human lunar landings.
The Flight 12 launch is expected to attract major global attention as SpaceX continues pushing the boundaries of reusable rocket technology and next-generation spaceflight systems.
