Key Takeaways
- On April 14, SpaceX executed a full-length static fire of the Starship V3 upper stage at its Texas launch site
- The Super Heavy booster underwent its own 33-engine test firing on April 15
- The upgraded V3 variant reaches 408 feet in height and boasts a payload capacity exceeding 100 tons to LEO
- This marks the debut flight for the V3 design, though it represents the program’s 12th test mission overall
- NASA has selected Starship as a human landing vehicle for its Artemis lunar exploration initiative
SpaceX has successfully executed two critical ground tests for its upgraded Starship vehicle, bringing the aerospace company one step closer to its targeted May launch window.

On April 14, the company ignited the upper stage engines of Starship V3 at its South Texas development facility. Twenty-four hours later, engineers conducted a separate static fire of the massive Super Heavy booster, simultaneously igniting all 33 Raptor engines while the vehicle remained anchored to the test stand.
Both engine tests ran to completion, with no premature cutoffs reported during either firing sequence.
SpaceX noted this marked the inaugural full-duration test for the third-generation upper stage. The company’s engineering teams are now analyzing telemetry data covering engine thrust, propellant flow systems, and structural response before authorizing the vehicle for flight operations.
A previous booster test attempt had concluded prematurely when ground systems encountered technical difficulties. The April 15 success eliminates that concern from the flight readiness checklist.
V3 Upgrades Bring Significant Performance Gains
The third-generation Starship represents a substantial leap in capability compared to earlier iterations. The fully assembled launch system measures 124 meters tall—equivalent to roughly 408 feet—and can transport over 100 metric tons to low Earth orbit.
This payload performance represents nearly triple the capacity of preceding Starship versions. The enhancement stems from next-generation Raptor engines installed on both the spacecraft and its booster stage.
While this will be the V3’s first journey to space, it counts as the Starship program’s 12th test mission overall.
Elon Musk indicated on April 3 that the upcoming test flight would occur “4 to 6 weeks away,” suggesting a launch timeframe in the first or second week of May.
Lunar Ambitions Hinge on Starship Development
Starship serves as a cornerstone element of NASA’s Artemis lunar exploration campaign, which seeks to land astronauts on the Moon for the first time since the Apollo era. The space agency has awarded SpaceX a contract to develop a human-rated landing system based on Starship technology, while Jeff Bezos’s Blue Origin separately develops its Blue Moon lander platform.
NASA successfully flew four astronauts around the Moon earlier this month, marking the first crewed lunar flyby in more than five decades. The agency currently plans its first astronaut landing mission for late 2028 under the Artemis IV designation.
Development delays with Starship have already forced schedule adjustments. The surface mission was initially slated for December 2025.
NASA’s Aerospace Safety Advisory Panel members have expressed concern about ongoing technical hurdles facing the Starship Human Landing System. Panel experts indicated that Starship test flights over the coming six months will likely prove decisive in determining whether the system can support crewed operations before 2030.
Jim Bridenstine, who previously led NASA, testified before a Senate Committee last September that without program modifications, the United States may not reach the lunar surface ahead of China’s own timeline.
SpaceX has not yet announced an official launch date for the next Starship test mission.
