Key Highlights
- Full-duration static fire of Starship V3’s upper stage successfully conducted April 14 at Starbase, Texas
- Super Heavy booster with 33 Raptor engines completed its own static fire test on April 15
- The upgraded V3 configuration reaches 408 feet in height and boasts 100+ ton payload capacity to LEO
- Flight 12 of the Starship program will mark the V3 variant’s maiden voyage
- NASA has selected Starship as a Human Landing System for Artemis lunar missions
SpaceX has successfully executed two critical engine tests for its enhanced Starship rocket, bringing the vehicle’s maiden flight significantly closer to reality.
On April 14, the aerospace company conducted a complete-duration firing of the Starship V3 upper stage at its South Texas development site. Twenty-four hours later, engineers ignited all 33 Raptor engines on the Super Heavy booster while the massive rocket remained firmly anchored to the test stand.
According to SpaceX, both engine firings achieved their full planned duration without premature cutoffs—a crucial indicator of system readiness.
The upper stage test represented a first for the Version 3 architecture. Engineering teams are now analyzing telemetry data covering engine thrust characteristics, propellant flow systems, and structural integrity before authorizing the next testing phase.
A previous booster test attempt was terminated prematurely due to ground infrastructure complications. The successful April 15 firing confirms those issues have been resolved.
Version 3 Brings Substantial Upgrades
The latest Starship iteration delivers notable improvements over its predecessors. Standing at 124 meters—exceeding 408 feet when fully assembled—the V3 can transport over 100 metric tons to low Earth orbit.
This represents nearly triple the cargo capacity of earlier Starship versions. The enhancement stems from next-generation Raptor engines installed throughout both the spacecraft and its Super Heavy first stage.
While this will be the twelfth Starship test mission overall, it marks the inaugural flight for the substantially redesigned V3 configuration.
Elon Musk indicated on April 3 that the next mission would launch within “4 to 6 weeks,” suggesting a flight window opening in early to mid-May.
Critical Role in America’s Lunar Return
Starship represents an essential component of NASA’s Artemis initiative to establish sustained human presence on the Moon. The space agency has awarded SpaceX a contract to develop a crewed lunar lander using Starship technology, alongside a parallel system from Jeff Bezos’s Blue Origin.
NASA recently completed its first crewed lunar flyby in over five decades, sending four astronauts around the Moon earlier this month. The agency currently targets late 2028 for the first surface landing under Artemis IV.
Starship development delays have already forced timeline adjustments. The original landing mission was scheduled for December 2025.
NASA’s Aerospace Safety Advisory Panel has expressed concerns that significant technical challenges persist with the Starship Human Landing System. Panel members emphasized that the next half-year of test flights will likely determine whether the vehicle can safely transport astronauts before 2030.
Former NASA Administrator Jim Bridenstine testified before a Senate Committee in September that without program acceleration, the United States may not reach the lunar surface before China’s planned landing.
SpaceX has not yet announced an official launch date for Flight 12.
