Flight 9 features the first reflight of a Super Heavy booster, Booster 14, which previously launched Flight 7. Of the 33 engines on the booster, 29 are flight-proven.

Unlike the previous four launches, Booster 14 will not attempt a catch at the launch tower and will be used to test several experiments, including controlling the booster flip direction, a more efficient high-angle-of-attack booster return, and engine-out capability during the final 3-engine landing burn.

• Ship objectives include deployment of 8 Starlink simulators, an in-space Raptor relight, and testing of Ship ver2 heatshield and flap design on reentry.
• "Following stage separation, the booster will flip in a controlled direction before initiating its boostback burn. This will be achieved by blocking several of the vents on the vehicle’s hotstage adapter, causing the thrust from Starship’s engines to push the booster in a known direction. Previous booster flips went in a randomized direction based on a directional push from small differences in thrust from Starship’s upper stage engines at ignition." Diagram by Killip.

The timing of the Flight 8 failure was similar to Flight 7 in January, which also featured several engine shutdowns and a loss of communications about eight and a half minutes after liftoff. However, SpaceX says the two failures had different causes.

“While the failure manifested at a similar point in the flight timeline as Starship’s seventh flight test, it is worth noting that the failures are distinctly different,” the company stated.

In the case of Flight 8, SpaceX said one of the center Raptor engines in Starship suffered a hardware failure, details of which the company did not disclose. That failure enabled “inadvertent propellant mixing and ignition” that caused the loss of the Raptor. Immediately thereafter, the other two center Raptor engines shut down, along with one of the three outer vacuum-optimized engines with larger nozzles. The vehicle then lost control authority.

The company said it made changes to the Raptors in the Starship upper stage, with “additional preload” on key joints and a new nitrogen purge system as well as improvements to the propellant drain system. A future version of Raptor in development will also have reliability improvements to address the problem seen on Flight 8.

On Flight 7 in January, SpaceX, said the vehicle suffered a harmonic response several times stronger than expected, creating additional stress on the vehicle’s propulsion system. That caused leaks that triggered a fire in the engine bay.

“The mitigations put in place after Starship’s seventh flight test to address harmonic response and flammability of the ship’s attic section worked as designed prior to the failure on Flight 8,” SpaceX said.

The agency is expanding the size of hazard areas in the United States and in other countries based on an updated "flight safety analysis" from SpaceX and because SpaceX will reuse a previously flown first-stage booster—called Super Heavy—for the first time.

The size of FAA-mandated airspace closures can expand or shrink based on the reliability of the launch vehicle. The failures of Starship earlier this year raised the probability of vehicle failure in the flight-safety analysis for Starship Flight 9, according to the FAA.

If SpaceX can reel off a series of successful Starship flights, the hazard areas will likely shrink in size.

Starlink Group 11-16 launch out of SLC-4E in California is currently scheduled for 2025-05-23 22:32 UTC, or 2025-05-23 15:32 local time (PDT). Booster 1075-18 to land on Of Course I Still Love You.

SpaceX is moving ahead with expansion plans at Vandenberg Space Force Base that will double its West Coast launch cadence and enable Falcon Heavy rockets to fly from California.

Last week, the Department of the Air Force issued its Draft Environmental Impact Statement (EIS), which considers proposed modifications from SpaceX to Space Launch Complex 6 (SLC-6) at Vandenberg.

At the heart of the request are three key items:

• Modifying the pad to support the launches of both Falcon 9 and Falcon Heavy rockets
• Constructing two new landing pads adjacent to SLC-6
• Increasing SpaceX’s permitted launch cadence from Vandenberg from 50 launches to 100

Starlink Group 12-15 launch out of LC-39A in Florida is currently scheduled for 2025-05-21 03:19 UTC, or 2025-05-20 23:16 local time (EDT). New booster 1095-1 to land on Just Read the Instructions.

Starship ignited its Raptor engines Monday morning on a test stand near SpaceX's Starbase launch facility in South Texas. The engine ran for approximately 60 seconds, and SpaceX confirmed the test-firing in a post on X: "Starship completed a long duration six-engine static fire and is undergoing final preparations for the ninth flight test."

SpaceX hasn't officially announced a target launch date, but maritime warnings along Starship's flight path over the Gulf of Mexico suggest the launch might happen as soon as next Wednesday, May 21. The launch window would open at 6:30 pm local time (7:30 pm EDT; 23:30 UTC).

Starlink Group 6-67 launch out of SLC-40 in Florida is currently scheduled for 2025-05-14 16:38 UTC, or 2025-05-14 12:38 local time (EDT). Booster B1090-4 to land on A Shortfall of Gravitas.
