SpaceX launched its eighth Starship test flight on Thursday, March 6, 2025, from its Starbase facility in South Texas. The mission aimed to advance the reusable rocket system’s development with a third successful booster recovery and a planned satellite simulator deployment by the Starship upper stage.

Flight 8 ended with mixed results as the Starship upper stage experienced a rapid unscheduled disassembly during its ascent burn. The Super Heavy booster, however, returned successfully to Starbase’s launch tower.

Super Heavy Booster Achieves 3rd Successful Catch

The Super Heavy booster, designated Booster 15, roared to life at launch, propelling the 400-foot-tall Starship stack skyward. Less than three minutes after liftoff, it separated cleanly from the upper stage and began its descent back to Starbase. 

The booster executed a pinpoint landing, getting caught midair by the launch tower’s massive “chopstick” arms. This marked the third test flight where SpaceX was able to successfully recover a Super Heavy booster, a critical step toward reducing costs by reusing the rocket’s first stage. 

The crowd at South Padre Island, watching from across the water, erupted in cheers as the Super Heavy booster settled into the tower’s grasp.

Starship Upper Stage Lost

The mission’s upper stage, known as Ship 34, faced a starkly different fate. Intended to deploy four mock Starlink satellites and splash down in the ocean about 66 minutes after launch, the spacecraft encountered trouble during its ascent. 

Videos posted on social media platform X showed Ship 34 disintegrating during its flight, echoing Flight 7’s upper-stage loss in January. SpaceX addressed the upper stage’s failure in a post on X. 

“During Starship’s ascent burn, the vehicle experienced a rapid unscheduled disassembly and contact was lost. Our team immediately began coordination with safety officials to implement pre-planned contingency responses. We will review the data from today’s flight test to better understand root cause. As always, success comes from what we learn, and today’s flight will offer additional lessons to improve Starship’s reliability,” SpaceX wrote in its post.

SpaceX has announced a new target date for Starship Flight 8. As per the private space company, Starship’s eighth flight test is scheduled for Thursday, March 6, with the launch window opening at 5:30 p.m. CT. 

Starship Flight 8 comes after SpaceX completed an investigation into the Starship upper stage’s loss during Flight 7.

Mission Targets

The upcoming mission will follow a suborbital trajectory, deploying four Starlink simulators that will burn up on reentry, as per a release from SpaceX. This also marks Starship’s first payload drop. A single Raptor engine relight in space is planned, alongside reentry experiments that should help pave the way for the Starship upper stage’s return and catch at the launch site in later missions. 

The Super Heavy booster will launch, execute a boostback burn, and attempt a catch by the tower’s chopsticks. If health checks on the booster or tower falter, or if the Flight Director withholds final approval, the booster will default to a trajectory for a soft splashdown in the Gulf of America. Sonic booms from the returning booster will be audible near the landing zone.

Improvements to Starship and Super Heavy

As noted by SpaceX, Starship’s forward flaps have been redesigned to reduce reentry heat exposure and simplify mechanisms. The Starship upper stage’s propulsion system has also gained a 25% propellant volume boost for longer flights. 

SpaceX has removed a number of tiles from Starship to stress-test vulnerable spots across the vehicle. The reentry profile is designed to intentionally stress the structural limits of the upper stage’s rear flaps while at the point of maximum entry dynamic pressure as well.

The Super Heavy booster, on the other hand, features upgraded avionics, a more powerful flight computer, enhanced power and network distribution, and integrated smart batteries.

SpaceX is set to launch its eighth test flight of the Starship rocket this Friday. Ahead of the most recent test in what could be the most revolutionary spaceflight program since NASA’s Apollo, SpaceX is clearing the air about what went wrong during its previous test flight, which resulted in the loss of the second stage during its ascension.

On January 16, SpaceX successfully launched Starship while also completing its second successful catch of the lower-stage booster.

However, the flight did not go as smoothly as initially anticipated, as the company lost Starship’s upper stage roughly eight minutes and twenty seconds into flight.

Now, the company is clarifying what happened that led to the demise of the upper stage, which SpaceX has identified with the recognition of “flashes” that occurred after vehicle separation.

SpaceX completes second catch of lower stage, but loses Starship

SpaceX says that a flash was observed roughly two minutes into its burn after vehicle separation. The flash, along with sensors that was a pressure rise in the attic, indicated a leak:

“Approximately two minutes into its burn, a flash was observed in the aft section of the vehicle near one of the Raptor vacuum engines. This aft section, commonly referred to as the attic, is an unpressurized area between the bottom of the liquid oxygen tank and the aft heatshield. Sensors in the attic detected a pressure rise indicative of a leak after the flash was seen.”

This was not the only flash that was observed. Two minutes after the first, another flash was seen, but this one was followed by sustained fires in the attic. These fires caused Starship’s engines to perform a controlled shutdown:

“These eventually caused all but one of Starship’s engines to execute controlled shut down sequences and ultimately led to a loss of communication with the ship. Telemetry from the vehicle was last received just over eight minutes and 20 seconds into flight.”

SpaceX clarified that Starship was destroyed and communication with the ship was lost before it was able to initiate any destruct rules for its Autonomous Flight Safety System. The company said this was “fully healthy when communication was lost.”

It went on to say that the “most probable root cause” of the loss was likely due to an environment not seen during testing:

“The most probable root cause for the loss of ship was identified as a harmonic response several times stronger in flight than had been seen during testing, which led to increased stress on hardware in the propulsion system. The subsequent propellant leaks exceeded the venting capability of the ship’s attic area and resulted in sustained fires.”

Nevertheless, Starship will launch for the eighth time soon, with CEO Elon Musk noting that the most likely date will be Friday. This could be the second of potentially 25 Starship launches planned for 2025.
