On Wednesday, May 5, Starship serial number 15 (SN15) successfully completed SpaceX’s fifth high-altitude flight test of a Starship prototype from Starbase in Texas. SN15 ascended, transitioned propellant, and reoriented itself for reentry and a controlled aerodynamic descent. The Raptor engines reignited to perform the landing flip maneuver before touching down for a nominal landing on the pad.
These Starship test flights improve our understanding and development of a fully reusable transportation system designed to carry crew and cargo on long-duration interplanetary flights, help humanity return to the Moon, and travel to Mars and beyond.
The SpaceX team attempted a high-altitude flight test of Starship serial number 15 (SN15) – our fifth high-altitude flight test of a Starship prototype from Starbase in Texas. SN15 has vehicle improvements across structures, avionics and software, and the engines that will allow more speed and efficiency throughout production and flight: specifically, a new enhanced avionics suite, updated propellant architecture in the aft skirt, and a new Raptor engine design and configuration.
Similar to previous high-altitude flight tests of Starship, SN15 is powered through ascent by three Raptor engines, each shutting down in sequence prior to the vehicle reaching apogee – approximately 10 km in altitude. SN15 performed a propellant transition to the internal header tanks, which hold landing propellant, before reorienting itself for reentry and a controlled aerodynamic descent.
The Starship prototype descended under active aerodynamic control, accomplished by independent movement of two forward and two aft flaps on the vehicle. All four flaps are actuated by an onboard flight computer to control Starship’s attitude during flight and enable precise landing at the intended location. SN15’s Raptor engines then reignited as the vehicle attempted a landing flip maneuver immediately before touching down on the landing pad adjacent to the launch mount.
A controlled aerodynamic descent with body flaps and vertical landing capability, combined with in-space refilling, are critical to landing Starship at destinations across the solar system where prepared surfaces or runways do not exist, and returning to Earth. This capability will enable a fully reusable transportation system designed to carry both crew and cargo on long-duration, interplanetary flights and help humanity return to the Moon, and travel to Mars and beyond.
The SpaceX team attempted a high-altitude flight test of Starship serial number 11 (SN11) – our fourth high-altitude flight test of a Starship prototype from Starbase in Texas. Similar to previous high-altitude flight tests of Starship, SN11 was powered through ascent by three Raptor engines, each shutting down in sequence prior to the vehicle reaching apogee – approximately 10 km in altitude. SN11 performed a propellant transition to the internal header tanks, which hold landing propellant, before reorienting itself for reentry and a controlled aerodynamic descent.

On March 3, Starship serial number 10 (SN10) completed SpaceX’s third high-altitude flight test of a Starship prototype as it successfully ascended, transitioned propellant, and reoriented itself for reentry and an active aerodynamic controlled descent. SN10’s Raptor engines reignited to perform the vehicle’s landing flip maneuver immediately before successfully touching down on the landing pad.
Test flights such as SN10’s are about improving our understanding and development of a fully reusable transportation system designed to carry both crew and cargo on long-duration interplanetary flights, and help humanity return to the Moon, and travel to Mars and beyond.
On Tuesday, February 2, Starship serial number 9 (SN9) completed SpaceX’s second high-altitude flight test of a Starship prototype from our site in Cameron County, Texas.
Similar to the high-altitude flight test of Starship serial number 8 (SN8), SN9 was powered through ascent by three Raptor engines, each shutting down in sequence prior to the vehicle reaching apogee – approximately 10 kilometers in altitude. SN9 successfully performed a propellant transition to the internal header tanks, which hold landing propellant, before reorienting itself for reentry and a controlled aerodynamic descent.
The Starship prototype descended under active aerodynamic control, accomplished by independent movement of two forward and two aft flaps on the vehicle. All four flaps are actuated by an onboard flight computer to control Starship’s attitude during flight and enable precise landing at the intended location. During the landing flip maneuver, one of the Raptor engines did not relight and caused SN9 to land at high speed and experience a RUD.
These test flights are all about improving our understanding and development of a fully reusable transportation system designed to carry both crew and cargo on long-duration, interplanetary flights and help humanity return to the Moon, and travel to Mars and beyond.
The Sentinel-6 Michael Freilich satellite, carried atop a SpaceX Falcon 9 rocket, lifts off from Space Launch Complex 4 at Vandenberg Air Force Base in California on November 21, 2020. Launch occurred at 9:17 a.m. PST (12:17 p.m. EST). The mission is an international collaboration between NASA and several partners, and it will collect the most accurate data yet on global sea level and how our oceans are rising in response to climate change. NASA’s Launch Services Program based at Kennedy Space Center was responsible for launch management.
