Starship’s Sixth Flight Test
On Tuesday, SpaceX conducted the sixth test flight of its powerful Starship rocket, dubbed the most potent ever built. The test marked a significant milestone, but a highly anticipated booster catch attempt was aborted due to an automated hardware check.
Launch and Booster Maneuver
The Starship system, comprising the Starship spacecraft and Super Heavy booster, lifted off from the Starbase facility in Texas around 5 p.m. ET. After propelling the spacecraft towards space, the booster separated, turned back, and steered towards the launch site. SpaceX had planned a precision landing into the “chopsticks” of the “Mechazilla” launch and landing structure.
Booster Abort and Engine Ignition
However, health checks triggered an abort of the catch attempt. The booster performed a pre-planned divert maneuver and made a soft splashdown in the Gulf of Mexico. Meanwhile, the Starship spacecraft ignited its six engines and entered a coasting phase. About half an hour later, it reignited an engine for reentry and executed a daring landing. Notably, this was the first successful in-space engine ignition for Starship.
Aggressive Reentry and Heat Shield Test
Starship aimed to test its limits during its reentry towards splashdown in the Indian Ocean. The company’s engineer explained that the spacecraft would be flown at an aggressive angle of attack, which would stress its ability to control using flaps. Additionally, some protective shielding had been removed to assess the vehicle’s resilience.
Safe Landing and Data Analysis
Despite the rough landing trajectory, Starship made a safe splashdown in the Indian Ocean. SpaceX engineer Kate Tice expressed that the vehicle had exceeded their predictions, emphasizing the importance of testing under extreme conditions.
Importance for NASA’s Artemis Program
This test flight marked a significant step in SpaceX’s partnership with NASA, which is targeting a lunar landing as soon as 2026. NASA plans to use Starship as the lunar lander for the Artemis III mission, which will involve docking with multiple fuel tankers for its journey to the Moon.
FAA Approval and Future Plans
The Federal Aviation Administration determined that the flight path of the test closely resembled an earlier one, so no additional licensing review was necessary. SpaceX’s goal in these test flights is to develop a system for rapidly recovering and reusing Starship components, reducing launch costs and turnaround times.
Historical Context and SpaceX’s Goals
Starship forms a cornerstone of SpaceX’s mission to eventually transport humans to Mars. The company holds government contracts worth nearly $4 billion for NASA’s Artemis program. The sixth test flight included improvements to the spacecraft’s heatshield, reflecting SpaceX’s iterative design approach.
Expert Perspectives and Future Expectations
SpaceX’s operations during the test were praised by experts, who speculated that the sea landing of the booster may have been a safety precaution due to the presence of the president-elect. The aborted catch attempt will likely influence SpaceX’s next steps, which could include ambitious flight tests and propellant transfer demonstrations.
