SpaceX has secured contracts with NASA valued at roughly $4 billion for the design and development of a human-rated lunar lander derived from the Starship model. This lander plays a pivotal role in NASA’s Artemis program, which aims to return astronauts to the Moon’s surface later this decade. To enable Starship to make the trip to the Moon, SpaceX will need to refuel it with super-cold propellants while in low-Earth orbit—a task that has never been undertaken at this scale before.
Elon Musk envisions Starship as the fundamental framework for interplanetary travel, facilitating the transport of both cargo and individuals to Mars, a long-standing ambition of his. Achieving this goal also hinges on the capability for orbital refueling. Musk recently indicated that SpaceX might be prepared to showcase ship-to-ship orbital refueling by 2026, a year later than the 2025 target discussed by NASA officials last December.
Additionally, Starship is slated to launch SpaceX’s forthcoming generation of Starlink Internet satellites. Before Thursday’s launch, ground crews loaded four Starlink prototypes into Starship’s payload bay to evaluate the rocket’s deployment system. Officials were keen to analyze the performance of Starship Block 2’s heat shield prior to attempting to safely recover the vehicle intact—similar to what SpaceX has already accomplished with the Super Heavy booster—in a future mission. However, the untimely conclusion of this test flight necessitates a postponement of those objectives.
SpaceX manages the development of Starship through an iterative cycle. Engineers generate new designs, conduct rapid tests, and then integrate the insights gained into subsequent iterations of the rocket. It’s not unexpected to witness a few rockets experiencing failures during this spiral development process. Nevertheless, consecutive failures, particularly those sharing numerous similarities, may indicate a deeper-rooted issue.
The flight plan leading up to Thursday’s mission was intended to send Starship on a trajectory that circled halfway around the globe from Texas, culminating in a controlled reentry over the Indian Ocean before splashing down northwest of Australia.
This test flight was meant to serve as a redo of the previous Starship launch that took place on January 16, when the rocket’s upper stage—a component also known as Starship—fell victim to fires ignited by leaking propellants in its engine compartment. Engineers concluded that the most probable cause of the propellant leak was a harmonic response several times more intense than anticipated, indicating that the vibrations during the ship’s ascent were resonating with the vehicle’s natural frequency. This resonance likely exacerbated the vibrations beyond the expected levels.
