Previous Starship missions
Mission IFT-3
- The third flight test of a fully integrated Starship.
- Integrated Test Flight IFT-3 (OFT-3).
- Expected: March 2024.
- Launch date: 14-03-2024 (NET).
Scheduled IFT-3
- 14-03-2024 launch (NET).
Updates IFT-3
- Electronic Thrust Vector Control (TVC): An advanced system for precise control of the rocket’s path
- Upgraded Flight Termination System (FTS): Enhanced safety measures for mission termination if necessary.
- Propellant Transfer Demonstration: A key feature for the HLS, involving transfer from a header tank to a main tank in microgravity.
- Launch Pad Improvements. Addition of a water-cooled steel plate for thermal protection and sound dampening. Improvements to the OLM, Orbital Launch Module, and “Mechazzilla,” the chopstick arms used to stack Starship on the Booster.
Flight objectives IFT-3
- Ascent burn of both stages. Controlled ascent.
- Opening and closing Starship’s payload door.
- Propellant transfer demonstration during the upper stage’s coast phase.
- Orbital insertion.
- Controlled reentry of Starship.

Evaluation IFT-3
Full stack positive
- As a result of investments in the capacity of the tank farm, fuel loading took place with a greater volume per minute than with IFT-1 and IFT-2 and was completed in a shorter time (as tested and planned). From GO for propellant load to Engine start was 02:00:00 and is now 01:15:00.
- On time.
- Launch window 1 used.
Full stack negative
- None.
Booster positive
- For the second time, all 33 Raptor engines on the Super Heavy Booster started up successfully and completed a full-duration burn during ascent.
- Following separation, the Super Heavy booster successfully completed its flip maneuver and completed a full boostback burn to send it towards its splashdown point in the Gulf of Mexico.
Booster negative
- Super Heavy successfully lit several engines for its first ever landing burn before the vehicle experienced a RUD (that’s SpaceX-speak for “rapid unscheduled disassembly”). The booster’s flight concluded at approximately 462 meters in altitude and just under seven minutes into the mission.
- Did not light all the expected engines for the landing burn.
- No soft landing.
Starship positive
- Starship executed its second successful hot-stage separation, powering down all but three of Super Heavy’s Raptor engines and successfully igniting the six second stage Raptor engines before separating the vehicles.
- Starship’s six second stage Raptor engines all started successfully and powered the vehicle to its expected orbit, becoming the first Starship to complete its full-duration ascent burn.
- While coasting, Starship accomplished several of the flight test’s additional objectives, including the opening and closing of its payload door (aka the pez dispenser,) and initiating a propellant transfer demonstration. Starship did not attempt its planned on-orbit relight of a single Raptor engine due to vehicle roll rates during coast. Results from these demonstrations will come after postflight data review is complete.
- Starship went on to experience its first ever entry from space, providing valuable data on heating and vehicle control during hypersonic reentry. Live views of entry were made possible by Starlink terminals operating on Starship.
Starship negative
- Raptor relight demo skipped.
- It appears that some tiles fell of from Starship during the reentry.
- No communication in the last phase of the flight.
- No soft landing.
- The flight test’s conclusion came during entry, with the last telemetry signals received via Starlink from Starship at approximately 49 minutes into the mission.
Next steps
Follow-up IFT-3
- Starship was spinning (around its longitudinal axis) because the aerodynamic flaps were not working properly.
- This made the fuel transfer test not possible.
- The uncontrolled spinning is also a problem for the reentry (plasma phase) because there are only heat-resistant tiles attached to one side of Starship.
- The tumbling made it impossible to perform the engine restart test.
- After the plasma phase there was no more contact with Starship,
- In the future, the FAA will provide 1 license for multiple launches.
- IFT-3 FAA mishap investigation.
- Rapid progress is needed for Starship, which is on the critical path for NASA’s Artemis 3 mission. Artemis 3 aims to land the first humans on the moon since the end of the Apollo era in the early 1970s. Artemis 3 is currently scheduled for 2026, giving Starship less than two years to meet NASA vehicle qualifications for landing astronauts on the lunar surface.
