SpaceX ramps Starship hiring as Elon Musk talks Texas rocket factory's "awesome" progress

After several successful tests last month, Elon Musk says that SpaceX’s South Texas Starship team is looking to rapidly expand in order to aggressively ramp up Starship manufacturing in a sign that the nascent rocket factory is making excellent progress.

Almost immediately after SpaceX successfully wrapped up its first and second explosive Starship tank tests last month, the company’s Boca Chica, Texas presence started to take on a new atmosphere, reminiscent of the rapid progress made at a since-mothballed Florida Starship facility. Perhaps thanks to the fact that SpaceX’s Boca Chica Starship facilities are adjacent to a dedicated test and launch facility just a mile down the road, it’s looking much less likely that a similar fate will befall its Texas presence.

Instead, SpaceX’s successful Starship tank tests – intentionally destroying two massive propellant tanks – are a testament to the progress the next-generation rocket is making in Texas. In fact, SpaceX CEO Elon Musk has effectively stated that after the most recent tank test, the company is now ready to shift gears and start building the first space-bound Starship prototypes, while the last week or two of SpaceX’s visible Texas activities make it clear that that shift is already well underway.

In simple terms, SpaceX now appears to be moving full speed ahead in a bid to manufacture, assemble, and test the first flightworthy, full-scale Starship prototypes. It’s worth noting that CEO Elon Musk has underestimated the challenge at hand several times in the last 18 or so months of Starship development, frequently suggesting that the first full-scale prototype of the spacecraft would be ready for a challenging flight test and maybe even its first orbital flights as early as 2019.

For a number of reasons, those ambitious targets were not met. To Musk’s credit, the executive is at least conscious of his tendency to be wildly optimistic when it comes to schedules and has effectively tacked on an asterisk that the schedules and deadlines he often publicizes tend more along the lines of “this time-frame is technically possible without breaking the laws of physics” than anything verging on pragmatism. With challenges as complex as those faced in spaceflight, let alone massive, fully-reusable rockets like Starship, it’s hard to be surprised that practical deadlines tend to be miles away from theoretically-possible minimums.

As such, it wouldn’t be unreasonable to feel a bit like the townspeople with a boy crying wolf, but there are arguably several reasons for optimism, this time around. Most importantly, as partially pictured above, SpaceX has completed four intentionally destructive tests with full-scale Starship hardware in just the last 2.5 months. Deemed unfit for flight, SpaceX pressurized Starship Mk1 with liquid nitrogen until it burst in November 2019, reaching an estimated 3-5 bar (45-75 psi).

SpaceX spent the following month upgrading both the methods and facilities used to build Starship prototypes in South Texas – a process that is still very much ongoing. However, two recent tests of Starship tanks built with some of those new methods and facilities have unequivocally proven that great progress is being made. The first ‘test tank’ managed 7.1 bar (105 psi) before it burst, while a second tank completed less than three weeks later reached 7.5 bar (110 psi) with water and 8.5 bar (125 psi) with liquid nitrogen on January 28th. Between those tests, Musk revealed that 6 bar was the bare minimum necessary for orbital Starship flights, while 8.5 bar would potentially offer the safety margins needed for crewed Starship flights.

In other words, SpaceX’s last two tank tests have effectively proved that – even with facilities and methods only partially upgraded – the company is ready to begin manufacturing the first truly flight-rated Starship prototypes. In response, Musk recently stated that he was going “max hardcore on” Starship design and production in Boca Chica and revealed that SpaceX would host a second South Texas jobs fair in three weeks to help rapidly staff its growing rocket factory.

Looking at the progress SpaceX has made in just the last week, it’s hard to fault Musk’s brimming enthusiasm. Now breaking in new semi-automated welding machines, upgraded production equipment, and two massive sprung structures (i.e. tents), SpaceX engineers and technicians are churning out improved steel rings, tank domes (bulkheads), smaller propellant tanks, and more at a breakneck pace relative to the last year of Starship work. Additionally, at least six of those new rings have been stacked together in two sections, likely representing the effective birth of the first flightworthy Starship – ‘SN01’.

With SpaceX’s new enclosed facilities, much of its South Texas work is now hidden. Still, from what’s visible, it’s safe to say that the company is well its way to completing the first flight – and possibly orbit – worthy Starship prototypes in the near future.

Tesla has a Cybercab problem nobody saw coming

Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.

Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”

Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.

The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.

Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.

The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.

Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”

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

Published

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.
