Spacecraft achieves remarkable flight test
The fourth test flight of SpaceX's Starship took place on June 6, 2024, marking a significant step forward for the company in its quest for reusable spaceflight. This flight, which involved the full Starship configuration, aimed for the Super Heavy booster to perform a controlled soft splashdown on a "virtual tower" in the ocean and for the spacecraft (the Ship) to survive the peak heating during atmospheric reentry.
The mission was a resounding success. Although one Raptor engine was lost early after liftoff, the booster completed its flight profile and executed a controlled splashdown in the Gulf of Mexico. Meanwhile, the Ship survived reentry despite significant forward flap damage and also completed a controlled splashdown in the Indian Ocean near the target zone.
The successful demonstration of a controlled ocean landing for the booster was a key step toward SpaceX's longer-term goal of catching the booster directly on the launch tower. The flight also validated Starship's reentry thermal protection performance, leading SpaceX to add a secondary ablative heat shield layer in future tests for improved durability.
Following the fourth test, the program progressed with the fifth flight targeting an actual booster tower catch. Future flights will focus on advanced milestones such as in-space engine relights and orbital readiness, all advancing SpaceX’s development toward a fully reusable megasystem for orbital and beyond orbital missions.
The successful test puts SpaceX on the right track for future missions, with plans to launch four more Starship test flights in 2024. Data collected during this mission will be crucial for improving the performance of the next flight.
In addition, NASA has selected the Starship as the first crewed lander for the Artemis program. The Artemis program aims to establish a research base in the Moon's south polar region by the end of the 2020s. SpaceX aims to be able to recover and reuse its two ships by the end of 2024.

The success of SpaceX's Starship test flight 4, despite an early Raptor engine loss, has furthered the company's research in space-and-astronomy and technology, as the controlled ocean landing validated the thermal protection performance and paved the way for future developments in reusable spaceflight. With NASA selecting the Starship as the first crewed lander for the Artemis program and SpaceX aiming to recover and reuse its ships by the end of 2024, the momentum in science and technology is palpable.
