SpaceX’s Starship rocket thundered into the sky over South Texas early Monday. It was the 14th test flight of the world’s most powerful launch vehicle. This time, however, the rocket’s massive upper stage squeezed out some extra oomph from its Raptor engines and accelerated to orbital velocity.

On all of Starship’s previous flights, SpaceX intentionally dialed back the full capability of the rocket to fly a suborbital trajectory, slow enough for Earth’s gravity to pull the vehicle back into the atmosphere before it could complete a full lap around the planet. After several successful suborbital flights in a row, SpaceX officials decided this launch should go all the way to low-Earth orbit. And it did.

What’s more, SpaceX packed 26 of the company’s newest generation of Starlink broadband satellites into the rocket’s cargo bay. One by one, the flat-packed satellites—too large to fit inside SpaceX’s workhorse Falcon 9 rocket—were released from Starship’s payload deployer using a system of pulleys and cables to eject the satellites overboard like a Pez dispenser spits out candy.

A dramatic morning

Starship Flight 14 began with a booming sendoff from Starbase, Texas, at 8:49 am EDT (7:49 am local time; 12:49 UTC) as 33 methane-fueled Raptor engines pushed the 407-foot-tall (124-meter) rocket off its launch pad. The engines generated up to 18 million pounds of thrust to propel the fuel-laden rocket into the sky over Starbase, SpaceX’s private spaceport just north of the US-Mexico border.

Heading east from South Texas, the rocket powered through the speed of sound and soared into the stratosphere before its Super Heavy booster stage detached from Starship’s upper stage. The booster executed a rapid high-altitude turnaround to begin thrusting back toward the Texas coast. Several minutes later, the Super Heavy first stage made a controlled splashdown in the Gulf of Mexico just off the coast of Starbase.

The upper stage continued its climb into space before shutting off its Raptor engines a little more than eight minutes into the fight. Up to this point, the rocket followed a similar trajectory as SpaceX’s previous Starship test flights.

The company’s flight control team had a few minutes to decide whether to proceed with the next phase of the flight: a restart of one of Starship’s Raptor engines to add the final bit of speed required to reach orbital velocity. For a brief period, it appeared as if SpaceX was going to forego the orbital flight and allow Starship to continue coasting toward a reentry over the Indian Ocean, as it had done many times before.

The question of what to do next centered on the performance of the rocket’s Raptor engines. One of the six Raptors on Starship shut down prematurely during its ascent burn, and the five others burned longer to compensate for the malfunction. Less of a worry for Starship’s orbital flight, but still a concern for future launches, was the apparent failure of two of the 33 Raptor engines on the Super Heavy booster—one during launch and another during the booster’s return maneuvers.

Dan Huot, a SpaceX commentator providing live updates on the company’s webcast of Monday’s flight, initially reported that mission managers were going to abort the orbit insertion burn. Officials ultimately decided to proceed. The failed Raptor engine was not the same one that needed to fire to place the rocket into low-Earth orbit and steer it toward reentry and splashdown at the end of the flight.

SpaceX engineers were being “extremely conservative” in their planning for Monday’s flight, Huot said. A worst-case scenario for the first orbital flight of Starship would have been a failure that stranded the 100-ton vehicle in orbit. That could have caused it to fall back to Earth in an uncontrolled manner, creating a potential risk to public safety.

“We were only going to go if we were very confident in the core systems that have to work to get you out of orbit once you’re up there,” Huot said. “We took some extra time, added some extra drama, but we were able to clear the … three center engines and do our first ever orbital insertion burn. So that was a huge success.”

The Raptor engine selected for the insertion burn performed flawlessly, reigniting for 19 seconds to give Starship the nudge it needed to overcome the pull of Earth’s gravity. The maneuver added approximately 204 mph to Starship’s speed, a little more than 1 percent of the rocket’s overall velocity, to reach a stable orbit at an altitude of about 171 miles (276 kilometers).

Delivering for Starlink

Achieving orbit meant SpaceX could continue with the next phase of the mission. This involved the first deployment of commercial-grade Starlink V3 satellites for the company’s global broadband network. SpaceX launched a batch of Starlink V3s on the previous Starship flight in July, but that mission was suborbital, and the satellites quickly burned up as they fell back into the atmosphere.

The Starlink V3s will bring significant upgrades to the Starlink constellation. The satellites can only launch on Starship. They’re too large to fit inside the payload fairing of the Falcon 9 rocket, which SpaceX has used to deploy more than 12,000 Starlinks since 2019. The Starlink V3s, each weighing about 2 metric tons (4,400 pounds) at launch, are fitted with larger power-generating solar arrays and improved antennas.

The changes enable each Starlink V3 platform to add 1 Tbps of capacity to the Starlink network, 10 times more than the older satellites launching on Falcon 9, according to SpaceX. There were 26 Starlink satellites aboard Monday’s launch. Future Starships could deliver up to 60 Starlink V3s to orbit on a single flight. On its website, SpaceX wrote that Starlink V3s will “greatly expand the network’s capacity and user speeds.”

Upgraded Starlink satellites will also improve the network’s performance for direct-to-device connectivity. Future Starlink V3s could also be used for SpaceX’s Starshield service for the US military. SpaceX reported that its satellite team established contact with all 26 Starlink V3s after separating from Starship.

The satellites launched Monday were initially deployed into a low-inclination orbit, ranging about 30 degrees north and south of the equator, due to strict range safety rules restricting overflight of populated areas during launch. SpaceX is expected to launch Starship into higher-inclination orbits as it gains flight experience with Starship and debuts new launch pads in Florida and Louisiana.

SpaceX’s first Starlink V3s had to wait a while for a ride to space, but Monday’s flight showed Starship is up to the task. SpaceX started phasing out Starlink launches on the Falcon 9 earlier this year. There are no more Falcon 9 launches for Starlink on SpaceX’s schedule at Cape Canaveral, Florida. Falcon 9 launches to place older-generation Starlink satellites into polar orbit will continue from Vandenberg Space Force Base, California, at least for a while longer.

Caleb Henry, director of research at Quilty Space, expects SpaceX to work on integrating the new capabilities of Starlink V3s into the Starlink network in the coming months. More already-built Starlink V3s will likely be on most of SpaceX’s next series of Starship flights.

“They just sat at a warehouse in Texas, as I understand it, because the satellites were finished well ahead of the launch vehicle,” Henry said in a live broadcast of Monday’s Starship flight hosted by Spaceflight Now (the author of this story was also a guest).

SpaceX said before Monday’s flight that this group of Starlink V3 satellites will be integrated into the broader constellation. They should begin serving customers as soon as a few weeks after launch, according to SpaceX, but it will likely take many more launches for Starlink customers to notice a difference in their service.

“It’s great that they have the capacity onboard in orbit, but until there is a meaningful number of V3 satellites launched, they won’t be the spacecraft that defines the user experience just yet,” Henry said.

Calling it a day

Soon after completing the satellite deployment sequence, SpaceX officials decided to bring Starship home earlier than planned, giving up on a chance to test the vehicle’s long-duration endurance in orbit.

“Out of an abundance of caution given the engine issue experienced during ascent, the flight control team decided to limit the duration spent on orbit and proceeded with de-orbiting Starship to a splashdown location in the northern Pacific Ocean,” SpaceX wrote in a recap of Monday’s test flight. “This area was one of two pre-coordinated landing zones identified before launch that was cleared of sea and air traffic.”

The de-orbit burn went off without a hitch, and Starship plunged back into the atmosphere over the Pacific Ocean, guiding itself toward a splashdown north of Hawaii, one of multiple backup return sites mapped out in advance of Monday’s flight. The reentry was uneventful, and Starship’s heat shield appeared to hold up well against temperatures up to 2,600° Fahrenheit (1,430° Celsius) as the vehicle streaked over the remote Pacific.

Like its most recent flights, Starship dropped belly-first through scattered clouds before turning upright for a final landing burn. The splashdown was right on target, with the final moments of descent in view of a buoy prepositioned at the backup landing zone.

Splashdown occurred at 11:57 am EDT (15:57 UTC), a little more than three hours after liftoff, three times longer than Starship’s previous suborbital flights. The original flight plan called for a mission lasting nearly 10 hours.

As expected, the vehicle tipped over and broke apart in a fireball upon reaching the ocean, and was unable to replicate the serendipitous intact splashdown on Starship’s last flight in July. SpaceX anticipates most of Starship’s water landings to have fiery endings, but the days of Starship splashdowns may be nearing their end.

“Most importantly, Starship made it to orbit,” Huot said after splashdown. “We did our first ever orbital insertion burn. We kept the drama up a little bit as we were going through that coast time making sure everything was good. We were only going do all this stuff today if we were really, really sure that those sea level engines on Starship were going to perform because we needed to do that de-orbit burn.

“We were able to get there,” Huot said. “We got on orbit. Teams continued to look at it. We were going to get the data that we wanted, so we made the call due to this earlier reentry to [near] Hawaii.”

What’s next for Starship?

SpaceX has a steady stream of Starships and Super Heavy boosters in production and testing at Starbase, setting up for an increasing cadence of flights in the coming months. The company has not announced any official launch dates, but a schedule of “upcoming high-profile missions” released by the Federal Aviation Administration’s Air Traffic Control System Command Center this week indicated the next Starship flight could take off from Starbase in October.

Ground crews are moving into testing and activation of a new Starship launch pad at NASA’s Kennedy Space Center in Florida, with an eye toward hosting a Starship launch there before the end of the year. A cavernous new Starship factory is also taking shape at Kennedy. SpaceX is expected to transport Super Heavy and Starship rockets to the Florida launch base from its factory in Texas until the new on-site production facility is complete.

The results from Monday’s test flight suggest that SpaceX still has work to do on the latest iteration of its Raptor engine. The Raptor 3 engine variant uses a lighter, streamlined design, combining a lower part count with higher thrust.

SpaceX has now encountered engine problems on each of the three Starship flights that have used Raptor 3s. During a May flight, one Raptor engine shut down prematurely on the Super Heavy booster, and another stopped running on Starship’s upper stage a few minutes later. Multiple Raptor engines failed to ignite on the launch pad for the next flight in July, prompting a last-second abort. SpaceX swapped out two of the engines before proceeding with a successful launch a week later.

Elon Musk, SpaceX’s founder and CEO, wrote on his social media platform X that the changes introduced with the Raptor 3 engine “greatly reduces mass and leak paths, but makes it harder to replace some parts.”

“While deleting parts sounds easy in theory, it is actually very difficult to figure out how to do so in practice and requires many iterations,” Musk continued. The inside of the Raptor 3 engine “has very complex geometry that can only be manufactured using highly modified 3D metal printing,” he wrote in another post.

Although the Raptor 3 is still a work in progress, the propulsion issues have not stopped SpaceX from making headway with Starship, and it’s unlikely the engine problems on Monday’s flight will delay the next Starship launch.

The FAA is also giving SpaceX the all-clear on Monday’s flight. The regulatory agency will not require SpaceX to conduct a formal mishap investigation. An FAA spokesperson told Ars: “All flight events for both the Starship vehicle and the Super Heavy booster occurred within the scope of planned and FAA authorized activities.”

Next on SpaceX’s to-do list will likely be an attempt to bring Starship back to Starbase for a catch by the launch pad’s giant mechanical arms, repeating a feat engineers have already accomplished with Super Heavy booster. Returning Starship to the launch site will require a reentry over land, necessitating additional safety reviews to ensure no undue risk to populated areas as the vehicle approaches Starbase. Eventually, SpaceX aims to make these landings routine enough to enable full and rapid reuse of Super Heavy and Starship.

Other near-term objectives for Starship include longer-duration orbital flights and then the first demonstration of in-orbit refueling, a prerequisite for future missions to land astronauts on the Moon under the auspices of NASA’s Artemis program.

In the meantime, expect Starship to launch many more Starlink satellites. Commercial and government demand for Starlink services, along with SpaceX’s longer-term plans for orbital data centers, will keep Starship plenty busy as engineers bring the rocket’s more advanced capabilities online.
