Flight Date Booster Ship Status Technical Discussion
BLOCK 1 FLIGHTS (2023-2024)
IFT-1 20 Apr 2023 Booster 7 Ship 24 Failure First integrated test of full stack. Multiple engine failures during ascent, loss of thrust vector control prevented stage separation. Vehicle tumbled and was destroyed by Flight Termination System at approximately 4 minutes. Significant pad damage occurred from 33-engine ignition without water deluge system. Post-flight analysis led to 63 corrective actions including pad reinforcement and vehicle upgrades.
IFT-2 18 Nov 2023 Booster 9 Ship 25 Failure Successfully demonstrated hot-staging separation technique for first time. All 33 engines ignited at liftoff. Booster experienced multiple engine shutdowns during boostback burn, terminated at 90 km altitude over Gulf. Ship 25 became first Starship to reach space, nearly completing 6-engine burn before propellant leak caused loss of communication between flight computers, triggering engine shutdown. Filter blockage identified as likely cause of failures.
IFT-3 14 Mar 2024 Booster 10 Ship 28 Partial Success Major improvement with nominal ascent on all 33 engines. Successfully demonstrated payload door operation and propellant transfer between header and main tanks. Booster completed boostback burn but lost control during landing burn, exploding at 462 meters altitude. Ship reached intended trajectory but skipped planned engine relight due to roll rates. Lost attitude control likely from blocked valves, reentered over Indian Ocean.
IFT-4 06 Jun 2024 Booster 11 Ship 29 Success First fully successful mission profile. Booster 11 completed entire flight including successful soft splashdown in Gulf of Mexico. Ship 29 survived complete reentry despite significant heat shield damage and near loss of forward flap. Provided uninterrupted live views throughout plasma phase of reentry. Demonstrated controlled splashdown in Indian Ocean. Primary goal of surviving maximum heating achieved.
IFT-5 13 Oct 2024 Booster 12 Ship 30 Success Historic first catch of Super Heavy booster by launch tower "chopstick" arms. Booster 12 successfully returned to launch site and was caught mid-air. Ship 30 featured upgraded ablative heat shield layer, completed controlled reentry and precise splashdown in Indian Ocean. Demonstrated key capability for rapid reusability. Major milestone in making Starship fully reusable.
IFT-6 19 Nov 2024 Booster 13 Ship 31 Success Last Block 1 flight. Booster splashed down in Gulf after tower issue prevented catch attempt. Ship 31 successfully completed in-space engine relight demonstration, critical for future orbital missions. Removed 2,100 heat shield tiles to test durability. Achieved targeted splashdown in Indian Ocean. Final test before transitioning to Block 2 vehicles with significant upgrades.
BLOCK 2 FLIGHTS (2025)
IFT-7 16 Jan 2025 Booster 14 Ship 33 Failure First Block 2 flight with upgraded engines and systems. Booster 14 successfully caught by tower for second time. Ship 33 (first Block 2 upper stage) experienced harmonic vibrations causing propellant leaks and fires in engine section. Vehicle lost shortly after hot-staging, exploding over Caribbean. Debris field caused commercial flight diversions. FAA investigation identified 11 corrective actions.
IFT-8 06 Mar 2025 Booster 15 Ship 34 Failure Booster 15 successfully caught, making three total catches. Ship 34 experienced center Raptor failure leading to leaks and engine section fire. Lost before Second Engine Cutoff (SECO). Problem traced to inadequate torque specifications on engine mount preloading. Four engines shut down prematurely (1 RVac, 3 sea-level), causing loss of attitude control. Breakup observed from Bahamas and Florida.
IFT-9 27 May 2025 Booster 14-2 Ship 35 Partial Success First reflight of Super Heavy booster (29 of 33 engines flight-proven). Booster tested at extreme 17-degree angle of attack but failed during landing burn due to methane transfer tube rupture from excessive aerodynamic forces. Ship 35 reached SECO but methane leak in nosecone pressurization system caused attitude control loss. Unable to deploy Starlink simulators or complete planned maneuvers. Tumbled during reentry but remained in designated corridor.
IFT-10 26 Aug 2025 Booster 16 Ship 37 Success First successful Block 2 ship after three failures. Booster 16 completed hover test over Gulf before splashdown. Ship 37 achieved all objectives: reached SECO, deployed 8 Starlink simulators (first payload deployment), completed 2-second in-space engine relight, and survived controlled reentry to Indian Ocean. Broke curse of Block 2 upper stages. Originally planned for Ship 36 which exploded during static fire.
IFT-11 13 Oct 2025 Booster 15-2 Ship 38 Success Final Block 2 flight and last launch from Pad 1 before conversion. First reuse of caught booster (Booster 15 from Flight 8). Marked one-year anniversary of first booster catch. Both stages completed successful missions, setting stage for Block 3 transition. Ship 38 completed all mission objectives including payload deployment and controlled reentry.
BLOCK 3 FLIGHTS (PLANNED 2025-2026)
IFT-12 Q1 2026 Booster 19
Booster 18
Ship 39 Planned First Block 3 flight from new Pad 2 with flame trench and water-cooled steel deck. Features Raptor 3 engines (99 MN thrust for booster), integrated hot-stage ring, relocated grid fins in methane tank, passive docking system. Booster 18 suffered LOX tank rupture during November 2025 proof testing, may be replaced by Booster 19. Likely suborbital profile to validate new systems before orbital attempts.
IFT-13+ 2026 TBD TBD Future Plans include first orbital flights, ship-to-ship propellant transfer demonstrations for NASA HLS, attempting ship catches (projected for flights 13-15), and operational Starlink V3 deployment missions. Block 3 designed for 100+ tons payload reusable, critical for Artemis lunar lander variant. SpaceX targeting 25 launches annually from Starbase, with additional launches planned from Cape Canaveral LC-39A and potentially SLC-37.

Key Technical Milestones and Evolution

Block 1 (2023-2024): Initial integrated testing phase focused on basic flight dynamics, stage separation, and reentry survival. Achieved first booster catch and validated heat shield design through maximum heating conditions. Six flights total, progressing from catastrophic failures to successful catches and controlled splashdowns.

Block 2 (2025): Introduced upgraded Raptor engines with higher thrust, improved heat shields, and refined systems. Experienced significant challenges with harmonic vibrations and propellant system failures in early flights. Five flights completed by October 2025, with only two ships successfully reaching their objectives. Demonstrated first booster reuse and payload deployment capabilities.

Block 3 (2026+): Major redesign featuring Raptor 3 engines producing approximately 99 meganewtons thrust on booster (compared to Saturn V's 33.36 MN). Integrated hot-stage ring eliminates expendable hardware, three larger grid fins mounted in methane tank, strengthened structure for increased performance. Designed for operational missions including lunar landing system for NASA Artemis program.

Infrastructure Development: Starbase expanded from single launch mount to multiple pads. Pad 1 being converted after Flight 11, Pad 2 near completion with flame trench and enhanced systems. Cape Canaveral LC-39A being modified for Starship, SLC-37 under consideration. FAA approved increase from 5 to 25 annual launches from Starbase.

The 50-meter (164-foot) Starship spacecraft had been designed to carry crew and cargo and sits atop a 70-meter-tall first-stage booster rocket. As part of the Artemis III mission, NASA has selected Starship to transport astronauts to the moon in late 2025, marking the first human journey there since the Apollo program concluded in 1972. Compared to NASA's Space Launch System (SLS), which has been under development for over a decade, Starship is larger and more powerful, with the capability to lift more than 100 metric tons into orbit.

SpaceX’s Starship spacecraft and Super Heavy rocket – collectively referred to as Starship – represent a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond. Starship will be the world’s most powerful launch vehicle ever developed, capable of carrying up to 150 metric tonnes fully reusable and 250 metric tonnes expendable. Super Heavy is the first stage, or booster, of the Starship launch system. Powered by 33 Raptor engines using sub-cooled liquid methane (CH4) and liquid oxygen (LOX), Super Heavy is fully reusable and will re-enter Earth’s atmosphere to land back at the launch site.

Starship is a fully reusable launch and landing system designed for travel to the Moon, Mars, and other destinations. The system leans on the company’s tested Raptor engines and flight heritage of the Falcon and Dragon vehicles. Starship includes a spacious cabin and two airlocks for astronaut moonwalks. Several Starships serve distinct purposes in enabling human landing missions, each based on the common Starship design. A propellant storage Starship will park in low-Earth orbit to be supplied by tanker Starships. The human-rated Starship will launch to the storage unit in Earth orbit, fuel up, and continue to lunar orbit. SpaceX’s Super Heavy rocket booster, which is also powered by Raptor and fully reusable, will launch Starship from Earth. Starship is capable of transporting crew between Orion or Gateway and the lunar surface.

NASA announced 30 April 2020 that three U.S. companies will develop the human landers that will land astronauts on the Moon beginning in 2024 as part of the Artemis program. These human landers are the final piece of the transportation chain required for sustainable human exploration of the Moon, which includes the Space Launch System rocket, Orion spacecraft, and the Gateway outpost in lunar orbit. The awardees for NASA’s Human Landing System contracts are Blue Origin of Kent, Washington, Dynetics (a Leidos company) of Huntsville, Alabama, and SpaceX of Hawthorne, California. These teams offered three distinct lander and mission designs, which will drive a broader range of technology development and, ultimately, more sustainability for lunar surface access.
