SpaceX successfully performed a soft splashdown of the Starship prototype S40 in the Indian Ocean during test flight 13 [1].
This milestone validates the vehicle's ability to execute a controlled descent and landing in a marine environment. Achieving a soft splashdown is a critical step toward ensuring the spacecraft can safely return to Earth from deep space missions.
The flight, designated as flight 13 [1], focused on demonstrating the precision and stability of the S40 vehicle [1] as it entered the atmosphere. Drone footage captured the final moments of the descent, showing the prototype maintaining its orientation before making contact with the water in the Indian Ocean [1].
Engineers designed the Starship program to be fully reusable, which requires the vehicle to survive the extreme heat and pressure of reentry. The S40 prototype served as the primary testbed for these specific landing maneuvers during this mission [1]. By targeting a specific zone in the Indian Ocean [1], SpaceX can analyze the impact data and structural integrity of the hull after a high-velocity descent.
The company has iterated through multiple prototypes to refine the flip maneuver and engine relight sequences necessary for a soft touchdown. This latest test confirms that the guidance systems can accurately steer the massive vehicle toward a designated coordinate, a prerequisite for future landings on land-based pads.
While the mission was a test of capabilities, the successful splashdown provides a baseline for the next phase of the Starship development cycle. The data gathered from the S40 flight will likely influence the design of future prototypes as the company moves closer to operational flights.

The successful soft splashdown of S40 indicates that SpaceX is refining the complex physics of atmospheric reentry and precision targeting. By proving the vehicle can land softly in the ocean, the company reduces the risk for future attempts to land the Starship back at the launch site, which is essential for the economic viability of a fully reusable rocket system.
