SpaceX’s Starship, the world’s most powerful rocket, experienced a fiery disintegration over the Indian Ocean on Thursday after suffering an anomaly during its fourth integrated test flight. While the launch and initial phases of the flight appeared successful, including a controlled ascent and stage separation, the vehicle failed to execute a planned soft landing.
The uncrewed Starship, consisting of the Super Heavy booster and the Starship upper stage, lifted off from SpaceX’s Starbase facility near Brownsville, Texas, at approximately 8:50 a.m. ET. The launch, streamed live by SpaceX, showed a seemingly flawless ascent, with the Super Heavy booster separating from the Starship upper stage as planned. This test aimed to achieve controlled re-entry and a soft landing in the ocean for both stages, marking significant progress toward the company’s goal of developing a fully reusable transportation system designed for deep space exploration.
However, the mission encountered difficulties during the final descent phase. According to SpaceX, the Starship experienced a rapid unscheduled disassembly, essentially exploding, as it approached the intended splashdown location in the Indian Ocean. The company acknowledged the anomaly but emphasized the valuable data collected throughout the flight. “Starship made it far! Splashdown imminent!,” SpaceX posted on its X account just before the signal was lost, highlighting the anticipation surrounding the landing attempt.
The Super Heavy booster, which was undertaking its own controlled descent back towards the Gulf of Mexico, also encountered issues. Although it successfully executed a boostback burn and entered the atmosphere, it experienced engine problems during the landing burn phase. SpaceX confirmed that the booster did not achieve a successful landing, ultimately leading to its destruction.
Despite the ultimate failure of both landing attempts, SpaceX characterized the test flight as a success, focusing on the advancements made compared to previous attempts. The company stated that the flight achieved several key objectives, including a successful hot-staging separation, controlled ascent, and significant data collection on re-entry dynamics. “A lot of exciting milestones achieved today,” SpaceX said in a statement. “These flights are all about improving the reliability and capabilities of Starship.”
This fourth integrated test flight aimed to build upon the lessons learned from previous attempts. The first test flight in April 2023 ended in an explosion shortly after launch. The second test in November 2023 achieved stage separation but also ended in explosions of both the booster and the Starship. The third test flight in March 2024 made significant progress, with the Starship reaching space and opening its payload door, but it ultimately burned up during re-entry.
SpaceX is developing Starship to transport humans and cargo to the Moon, Mars, and beyond. The fully reusable system is intended to significantly reduce the cost of space travel, making ambitious exploration missions more feasible. NASA has selected Starship as the lander for its Artemis program, which aims to return humans to the Moon by the end of the decade.
The company plans to analyze the data collected from this latest test flight to identify the root cause of the anomalies and implement corrective actions for future launches. SpaceX remains committed to the Starship program and its long-term vision of transforming space exploration.
