SpaceX is aiming to launch its mega rocket Starship's ninth test flight from Starbase, Texas, this coming week. The announcement was made on X (formerly Twitter) by company CEO Elon Musk. His post also contained some additional information about Mars missions that might excite space enthusiasts.

On May 13, Elon Musk reshared SpaceX's post comprising pictures and videos of Starship undergoing extended 'static fire' test, and wrote, "Just before the Starship flight next week, I will give a company talk explaining the Mars game plan in Starbase, Texas, that will also be live-streamed on X."  The development of Starship, the company's massive and fully reusable rocket, as well as the most powerful ever constructed, is deeply connected to the goal of establishing human settlements on Mars, a long-standing ambition of Elon Musk. 



 

While Musk did not specify any specific date in his post, he confidently reported a declaration made by user Dima Zeniuk (@DimaZeniuk) that stated on May 15, "SpaceX is going to launch Starship 9 in 6 days." This sets the exact date between May 21 and May 22. 



 

The approval for the test flight is still pending from the U.S. Federal Aviation Administration (FAA). The FAA is currently looking into what happened during Flight 8 on March 6, where the super heavy booster did its job, but the Starship upper stage blew up 10 minutes after liftoff. Flight 7, which took place in January, also faced issues, but they differed a bit from those seen in Flight 8. As optimistic as Elon Musk is about the next week's test flight, SpaceX needs the FAA to approve their report on the incident and any fixes they have made before Flight 9 can take off. 

SpaceX's 9th flight will see the first reuse of the Super Heavy booster, B14, with 29 of its 33 Raptors being flight-proven. B14 was also previously used for Flight 7. The mission will also attempt to achieve engine cutoff with the Starship upper stage and perform the inaugural re-entry of a Block-2 Starship, featuring enhanced flaps and other modifications. The flight aims to accomplish the milestones that Flights 7 and 8, using earlier Block 2 prototypes, were unable to reach. This will also be Starship's 9th mission and 3rd mission of 2025, as stated on Next Spaceflight.

SpaceX's Starship is considered the most powerful launch vehicle ever built. SpaceX's Starship system comprises the Starship spacecraft and the Super Heavy rocket, which is reusable and designed for carrying crew and cargo. This powerful system can carry up to 150 metric tons when fully reused and can lift an impressive 250 metric tons in an expendable configuration, enabling missions to Earth orbit, the Moon, Mars, and other distant locations. To enable the transport of 100 tons of cargo to Mars, Starship utilizes a specialized tanker, which is essentially a Starship spacecraft without windows, to fuel the main Starship spacecraft while in low Earth orbit before its journey to the Red Planet. This on-orbit refueling method becomes highly cost-effective if the tanker vehicles are reusable, as the primary expense then becomes just the relatively low cost of the Oxygen and Methane propellant, as reported on SpaceX's official website. The launch will happen at Orbital Launch Pad A, Starbase, Texas, USA, one of the world’s first commercial spaceports designed for orbital missions, as per Next Spaceflight.
