Less than 48 hours after Starship SN8’s (successful) demise, something on or around a metal stand holding up SpaceX’s next completed Starship collapsed, causing the rocket to rapidly tilt sidewise and smash into the assembly building containing it.

Put simply, launch vehicles very rarely designed or expected to survive the kind of structural loads the fall and impact put Starship SN9 through and the early prognosis – prior to any up-close observation – was not not great. Weighing at least 50-70 metric tons (110,000-155,000 lb), any other rocket – and possibly even Starship itself – should have been damaged beyond repair from anything less than a minor bump.

Instead, Starship SN9 – fully assembled and perhaps just a few days away from a scheduled transport to the launch pad – shifted some 10 degrees (~10 m/30 ft) in a few seconds, seemingly coming to rest against scaffolding and the interior wall of SpaceX’s “high bay” assembly building. Had Starship fallen 180 degrees in the opposite direction, the results could have been catastrophic, potentially falling without a wall to stop it onto a Super Heavy booster section that could have had workers inside it. Luckily, the (hopeful) wakeup call was apparently benign, with SpaceX escaping loss of life or limb and avoiding any catastrophic damage.

Some ~18 hours after the above tour, the stand holding up Starship SN9 apparently collapsed.

Perhaps even worse, less than a day prior, a number of VIPs, SpaceX executives, investors, and even Elon Musk himself were touring the company’s Starship factory and standing feet away from SN9 itself. The most likely culprit of SN9’s fall may even be visible in photos taken by Steve Jurvetson, one such investor. In a few of those photos, Starship’s steel work stand – a staple of SpaceX’s Starship factories for ~18 months – appears to be precariously balanced upon five or six jacks with nothing more than gravity, SN9’s own mass, and some counterweights hold them together.

If those jacks – as they appear to be – weren’t bolted to the high bay’s concrete foundation or Starship SN9’s work stand, it could have been unintuitively easy to trigger a collapse like the one that occurred, perhaps requiring a minor bump with a forklift, a particularly extreme gust of wind, or some other kind of lateral force.

Regardless of why it happened, the end result was the same. Somewhat miraculously, Starship SN9 – as photos would soon show – appeared to be almost entirely unscathed, baring no obvious hull damage. The rocket’s fore and aft starboard flaps, however, were clearly crumpled. In fact, it’s possible that the crumpling of those largely empty, thin-skinned flaps acted just like the crumple zones designed into modern cars, essentially soaking up the energy of SN9’s impact with the wall and saving the rest of the rocket.

Still, the reality is that Starship SN9’s prognosis is still unlikely to be good, even if crumpling flaps seemingly prevented the rocket from becoming an unequivocal write-off. Depending on how strong SN9’s flaps were, the force of the impact could have easily been transferred into the structural hinges that connect them to Starship, warping internal stiffeners, the hinge mechanism itself, or even the entire curvature of its cylindrical steel hull.

If somehow limited to just the hinges or, even less likely, if the flaps took almost all of the impact energy, SN9 might be repairable. Even then, it’s unlikely that SpaceX will be able to hold to the schedule previously discussed on Teslarati, meaning that Starship SN9’s journey to the launch pad probably isn’t going to happen on Monday, December 14th. In the meantime, SpaceX will likely kick work on Starship SN10 – perhaps just a week or two behind SN9 – into full gear.

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady

Published

on

SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.

Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.

This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.

This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.

Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.

Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.

The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.

Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.

For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.

Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.

Tesla Assisted Driving expands to tenth EU country

Published

on

Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.

Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.

The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.

Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.

In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.

Tesla starts showing how FSD will change lives in Europe

The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.

The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.

These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.

However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.

Tesla expands Robotaxi geofence in Houston with an ode to SpaceX merger

Published

on

Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.

Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.

The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.

The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.

Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.

Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.

Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.

Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.

Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.

The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.

Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
