SpaceX sends Falcon 9’s West Coast drone ship to the Panama Canal in surprise move

In a surprise turn of events, SpaceX has decided to send Just Read The Instructions (JRTI) – one of the company’s two autonomous spaceport drone ships (ASDS) – from Port of Los Angeles to either the Gulf or East Coast.

The likely destination: either Port Canaveral, Florida or Port of Brownsville, Texas. This move comes as the company enters a major lull in launch activities from its West Coast SLC-4 pad, situated in California’s Vandenberg Air Force Base (VAFB). Lacking manifested launches, SpaceX has gone as far as redistributing almost all of its VAFB-based launch team and laying off those that could not move to Texas or Florida. As early as the first half of 2020, this major move east could easily culminate in the end of all West Coast SpaceX fleet activity, aside from a rare fairing retrieval or two.

On June 12th, SpaceX successfully launched what is expected to be its last West Coast mission for at least 6-9 months, while drone ship JRTI was most recently used to recover a VAFB-launched Falcon 9 booster during the January 11th launch of Iridium NEXT-8. Unexpectedly, it appears that Falcon 9 B1049.2’s landing aboard JRTI will be the drone ship’s last West Coast recovery for quite some time.

On August 1st, the approximately 300 foot by 170 foot converted barge departed its well-worn Port of Los Angeles berth behind tugboat “Alice C”. In fact, the drone ship’s departure went unknown for a solid 12-24 hours before a member of the unofficial SpaceX subreddit (/r/SpaceX) discovered paperwork filed with the Panama Canal Authority for an August 15th passage.

Back in January 2019, SpaceX fairing recovery vessel Mr. Steven (now GO Ms. Tree) – in a bit of what now is obvious foreshadowing – began a very similar ~5000 mi (8000 km) journey, traveling from Port of LA to Port Canaveral via the Panama Canal. Mr. Steven, however, is a far faster ship and sustained a solid 15-20 knots (17-22 mph) over the entire voyage, while drone ship JRTI – towed the entire way – will have to suffice with an average speed less than half that.

Where to?

Assuming a day-long canal passage, JRTI’s journey to Port Canaveral or Brownsville would take no less than three weeks (~22 days) from start to finish, indicating a likely arrival at the unknown final destination in the third week of August. The two probable destinations, Texas and Florida, would both arguably make sense.

In Florida, SpaceX drone ship Of Course I Still Love You (OCISLY) is now tasked with handling the vast majority of SpaceX’s non-LZ booster recoveries, including Falcon Heavy center cores. In February 2018, CEO Elon Musk noted that a third drone ship (aside from JRTI & OCISLY) was “under construction” with the intention of allowing SpaceX to conduct Falcon Heavy launches where the center core is expended and both side boosters land at sea.

Perhaps SpaceX analyzed its fairly short West Coast manifest and decided that it would be even faster (and cheaper) to simply send JRTI East. Falcon Heavy’s next (public) launch is scheduled no earlier than late 2020, ruling out that as a primary motivation, but SpaceX is also about to begin operational Starlink launches that will demand an unprecedented cadence. Starlink’s cadence requirements could be so high that a second dedicated drone ship is necessary to prevent SpaceX’s internal manifest from delaying and generally disrupting its customers’ launches, thus explaining JRTI’s move.

At the same time, the spectacular pace of SpaceX’s orbital Starship prototype construction could very well demand the use of a large ocean-based landing platform in the near-term, at least according to Elon Musk’s recent comments on the subject of the first Starship test flights. Per Musk, either or both of SpaceX’s two Starship Mk1 (technically Mk1 & Mk2) prototypes could be ready for their first significant flights as early as September 2019, initially targeting altitudes of at least 20 km (12 mi).

Somewhat coincidentally, Starship’s tripod fin-legs – circa. a September 2018 design update – would actually almost fit inside the span of a Falcon 9 booster’s deployed landing legs (~18m diameter). This is to say that SpaceX’s two drone ships may already be large enough (give or take) to support Starship and Super Heavy booster landings. Given that the SpaceX plans to eventually put one or both of the in-work orbital Starship prototypes through an increasingly intensive series of high-speed, high-altitude (but still suborbital) tests before the first orbital flights, a drone ship may be necessary for the same reasons that not all Falcon 9 boosters can conveniently return to land during recovery.

Regardless of the ultimate purpose of drone ship JRTI’s move, it is undoubtedly a sign that things are about to get even more interesting and exciting in the world of SpaceX.

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.
