SpaceX’s first flight-proven Starship takes another step towards reuse
Nine days after becoming the first full-size prototype to survive a high-altitude launch and landing, SpaceX has installed Starship SN15 at the second of two identical launch mounts to prepare for potential reuse.
On May 5th, after a week or two of several minor delays, Starship SN15 – the fifth full-size prototype of its kind – lifted off from SpaceX’s Boca Chica, Texas launch pad under the thrust of three Raptor engines. Like all four of its predecessors, the 50-meter-tall (165 ft) steel rocket easily ascended to an apogee greater than 10 km (6.2 mi), shutting down one Raptor every ~90 seconds to its keep velocity low. When the final engine cut off, SN15 arced over onto its belly and free-fell to around half a kilometer above the ground, using four hollow steel ‘flaps’ to control its orientation like a skydiver’s limbs.
The most radical maneuver came around six minutes after liftoff when the sideways Starship reignited two or three of its Raptors, aggressively flipped into a nose-up position, deployed six stubby landing legs, and gently touched down a few hundred feet east of the stand it took off from.
Despite a fairly large fire that burned for several minutes after touchdown, SpaceX ultimately found itself – for the first time ever – with a full-size Starship prototype that survived its inaugural ~10-km launch and landing. A careful process of safing and securing then followed as operators commanded (or monitored) SN15 to disarm explosive flight termination system (FTS) charges, vent any remaining propellant, and eventually depressurize its fuel and oxygen tanks.
Unlike Starhopper, SN5, and SN6 – which also survived flights – SpaceX was apparently able to safe SN15 without any real issues and recovery teams were able to approach the rocket within a few hours of landing instead of the 12-24+ hours that were normal prior. SpaceX also debuted a sort of supersized version of the ‘Octagrabber’ robots that remotely secure Falcon boosters after drone ship landings, allowing the recovery team to secure Starship SN15 to a stable platform and transporter without a crane.
-->No longer at risk of toppling over, Starship SN15 then… sat where it landed. Less than two days after touchdown, CEO Elon Musk unexpectedly revealed that SpaceX “might try to refly SN15 soon,” indicating that initial post-flight inspections had revealed that the first flight-proven three-engine Starship was in excellent condition. SN15 would ultimately spend another four days (six total) sitting on a transporter at the landing zone. On May 11th, SpaceX rolled Starship SN15 from its landing spot to “Pad B” – the second of two identical suborbital launch mounts.
Perhaps due to stormy weather and high wind gusts in the area, SN15 once again sat still – this time for another three days. Ultimately, the Starship prototype was rapidly lifted onto Pad B’s launch mount, secured, and detached from the crane in a matter of hours of May 14th – possibly the smoothest pad installation yet. In the two days since then, SpaceX has begun more in-depth inspections that will ultimately determine whether the first flight-proven Starship is truly fit for a second launch.
That process likely wont take more than a few days and even if SN15 isn’t deemed (re)flightworthy, there’s still a very good chance SpaceX will put the Starship through some kind of test(s) before it’s retired. Stay tuned for more details likely to come this week.

SpaceX’s Starship program is already bouncing back from Booster 18 fiasco
Just over a week since Booster 18 met its untimely end, SpaceX is now busy stacking Booster 19, and at a very rapid pace, too.
SpaceX is already bouncing back from the fiasco that it experienced during Starship Booster 18’s initial tests earlier this month.
Just over a week since Booster 18 met its untimely end, SpaceX is now busy stacking Booster 19, and at a very rapid pace, too.
Starship V3 Booster 19 is rising
As per Starbase watchers on X, SpaceX rolled out the fourth aft section of Booster 19 to Starbase’s MegaBay this weekend, stacking it to reach 15 rings tall with just a few sections remaining. This marks the fastest booster assembly to date at four sections in five days. This is quite impressive, and it bodes well for SpaceX’s Starship V3 program, which is expected to be a notable step up from the V2 program, which was retired after a flawless Flight 11.
Starship watcher TankWatchers noted the tempo on X, stating, “During the night the A4 section of Booster 19 rolled out to the MegaBay. With 4 sections in just 5 days, this is shaping up to be the fastest booster stack ever.” Fellow Starbase watcher TestFlight echoed the same sentiments. “Booster 19 is now 15 rings tall, with 3 aft sections remaining!” the space enthusiast wrote.
Aggressive targets despite Booster 18 fiasco
SpaceX’s V3 program encountered a speed bump earlier this month when Booster 18, just one day after rolling out into the factory, experienced a major anomaly during gas system pressure testing at SpaceX’s Massey facility in Starbase, Texas. While no propellant was loaded, no engines were installed, and no one was injured in the incident, the unexpected end of Booster 18 sparked speculation that the Starship V3 program could face delays.
-->Despite the Booster 18 fiasco, however, SpaceX announced that “Starship’s twelfth flight test remains targeted for the first quarter of 2026.” Elon Musk shared a similar timeline on X earlier this year, with the CEO stating that “ V3 is a massive upgrade from the current V2 and should be through production and testing by end of year, with heavy flight activity next year.”
Considering that Booster 19 seems to be moving through its production phases quickly, perhaps SpaceX’s Q1 2026 target for Flight 12 might indeed be more than feasible.

Elon Musk makes a key Tesla Optimus detail official
“Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote on X.
Tesla CEO Elon Musk just made a key detail about Optimus official. In a post on X, the CEO clarified some key wording about Optimus, which should help the media and the public become more familiar with the humanoid robot.
Elon Musk makes Optimus’ plural term official
Elon Musk posted a number of Optimus-related posts on X this weekend. On Saturday, he stated that Optimus would be the Von Neumann probe, a machine that could eventually be capable of replicating itself. This capability, it seems, would be the key to Tesla achieving Elon Musk’s ambitious Optimus production targets.
Amidst the conversations about Optimus on X, a user of the social media platform asked the CEO what the plural term for the humanoid robot will be. As per Musk, Tesla will be setting the plural term for Optimus since the company also decided on the robot’s singular term. “Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote in his reply on X.
This makes it official. For media outlets such as Teslarati, numerous Optimus bots are now called Optimi. It rolls off the tongue pretty well, too.
Optimi will be a common sight worldwide
While Musk’s comment may seem pretty mundane to some, it is actually very important. Optimus is intended to be Tesla’s highest volume product, with the CEO estimating that the humanoid robot could eventually see annual production rates in the hundreds of millions, perhaps even more. Since Optimi will be a very common sight worldwide, it is good that people can now get used to terms describing the humanoid robot.
-->During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-Optimi-per-year production line at the Fremont Factory. Giga Texas would get an even bigger Optimus production line, which should be capable of producing tens of millions of Optimi per year.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.
