SpaceX preparing giant crane to assemble Starship’s first Florida launch tower

SpaceX has begun staging and assembling parts of a giant crane it will soon need to stack Starship’s first East Coast launch tower and install other major launch pad components.

The presence of the base of that crane at SpaceX’s NASA Kennedy Space Center (KSC) Launch Complex 39A was visually confirmed by NASASpaceflight.com photographers during a weekly aerial tour of the area on June 3rd. Four days later, Teslarati photographer Richard Angle observed more major crane components on their way to Pad 39A, including the crane’s cabin.

More likely than not, the crane SpaceX or its contractor has begun assembling at 39A is a Liebherr LR 11350, the same kind of crane the company used to assemble Starship’s first orbital launch site and tower in South Texas. In fact, given how few LR 11350s there are in existence, it’s entirely possible that it’s the exact same crane. Assembly of that crane began around April 2021 and took a month and a half, at which point it was finally ready to lift an extended boom long enough to assemble a tower almost 500 feet (~150 meters) tall.

Pad 39A’s Starship launch tower is expected to be very similar to Starbase’s, although it will undoubtedly carry over numerous design changes thanks to lessons learned while building and outfitting the first tower. In fact, SpaceX has already assembled five of the nine individual sections that will eventually be stacked to form that tower, and one such change is already obvious. Instead of stacking each tower section as soon as its barebones framework is complete, SpaceX is taking a more methodical approach to its second launch tower. In an apparent attempt to limit the amount of work that needs to be done at Pad 39A itself, each of those segments is being thoroughly outfitted with secondary structures (ladders, doors, walkways, frames, raceways, etc.) before stacking.

SpaceX may even pre-install most of the thousands of feet of plumbing needed to connect a Starship to ground systems located around 90 meters (~300 ft) below it. Once stacked, each section – including all those partial propellant and gas lines – will still need to be joined together, but that process should be far easier than fully installing all the systems the tower needs to do its job. Outfitting Starbase’s launch tower, for example, took SpaceX around half a year and, to some extent, is still ongoing 11 months after the final stack. That likely explains why Starship’s 39A tower section assembly appears to be taking more time. With any luck, partially combining the outfitting and section assembly stages will significantly expedite final assembly, as far less work will need to be done at extreme heights or require a skyscraper-sized crane.

Through Starbase, SpaceX has already demonstrated the ability to stack a Starship launch tower from its unoccupied concrete base to its final height of ~145 meters (~475 ft) in about two months flat. While SpaceX will have to slalom its way around Pad 39A’s busy launch manifest, there’s no reason to believe that Starship’s first Florida launch tower won’t be stacked at least as quickly.

Aside from the arrival of crane parts, SpaceX has also made great progress on the Starship launch site itself. In the last few weeks, the company appears to have completed several significant concrete pours on the tower base. SpaceX has also installed all six of the pedestal-like orbital launch mount’s legs after months of foundation work. Elsewhere at Cape Canaveral, a different team has made excellent progress assembling the massive donut-like platform that will sit on top of those legs. Due to its extreme weight (possibly around 300 metric tons, per Elon Musk’s comments on the Starbase mount), the same LR 11350 crane will also be needed for that major installation milestone.

Plenty of parts are still missing, of course. Four tower sections still need to be assembled. Starship’s first Florida launch tower will need its own set of two ‘chopstick’ arms for lifting and (maybe) catching Starship and Super Heavy, as well as a third swinging quick-disconnect arm to connect Starship to ground systems. Aside from delivering several new tanks, SpaceX has also made no apparent progress on adding a massive methane propellant farm to Pad 39A, and it’s possible that the pad’s oxygen farm will also need to be expanded. Propellant storage has proven to be a major headache for SpaceX at Starbase.

Nonetheless, SpaceX is making great progress on most of the most difficult parts of Starship’s first Florida launch site, and there’s a good chance that just like its launch mount, work on the pad’s tower arms is already underway somewhere offsite. A great deal of work remains to be done but SpaceX is still well on its way to launching Starships out of Kennedy Space Center in the not-too-distant 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.
