On July 2nd, Twitter user Sideralmente (@astroperinaldo) spotted a sooty Falcon 9 Block 5 booster arriving at SpaceX’s Pad 39A hangar facilities, currently operating as a sort of defacto refurbishment hub.

Likely a prelude to a near-term launch, SpaceX has several missions scheduled over the next few months. More likely than not, all of them will fly on flight-proven Falcon 9 boosters, now so common that launching new boosters has started to feel exceedingly rare and unusual. July 2nd’s booster spotting is also a rare (albeit slightly less rare) treat, given the general lack of access (aside from a bus tour) members of the public have to Kennedy Space Center’s operational facilities and the total lack of access they have to Cape Canaveral Air Force Station, home of SpaceX’s most active launch pad (LC-40).

CRS-18

Up next for SpaceX is Cargo Dragon CRS-18, the spacecraft’s second International Space Station (ISS) resupply mission this year. At least over the last 2-3 years, SpaceX and NASA have been fairly consistent with Cargo Dragon launches in the winter, late-spring/early-summer, and late-fall (Q1, Q2/Q3, Q4) for an average of three launches annually. 2018/2019 is no different: CRS-16 launched in early-December 2018 and CRS-17 in early-May 2019, while CRS-18 is scheduled to launch NET 7:35 pm ET, July 21st and CRS-19 is targeted for early-December 2019.

Meanwhile, CRS-18 is also expected to be the first time a NASA mission launches on a flight-proven Falcon 9 Block 5 booster, potentially paving the way for NASA’s first launch on a twice-flown Block 5 booster with CRS-19 – hopefully later this year. Of course, that subsequent milestone will depend on a successful launch and landing during CRS-18. Falcon 9 booster B1056 – previously tasked with launching CRS-17 on May 4th, 2019 – is assigned to the mission and has been speedily refurbished for its next mission. Assuming the static fire goes well and there are no anomalies over the next 11 days, B1056 will launch twice in 78 days, a close second to B1048, B1052, and B1053 – all tied for first place at 74 days.

AMOS-17

Following CRS-18, SpaceX’s next launch is expected to occur soon after, launching Spacecom’s AMOS-17 communications satellite on a Falcon 9 (likely flight-proven) no earlier than early-August, although the tail-end of July is also a possibility. This mission will be extremely symbolic, owing to the fact that AMOS-17 is effectively an insurance-funded replacement for AMOS-6, destroyed on September 1st, 2016 when Falcon 9 suffered a catastrophic failure.

Thankfully, since that failure nearly three years ago, Falcon 9 has performed admirably, suffering no publicly-known failures or partial failures during its primary mission, although SpaceX has suffered two failed booster landing attempts over the same period.

Built by Boeing, AMOS-17 is likely just days away from being shipped to Florida to prepare for launch, assuming it’s not already on site. (Boeing)

It’s possible that the mystery booster spotted above is meant for AMOS-17, although that’s far from certain. Based on an image showing the core number, it is almost certainly B104X, while the second digit could easily be a 7 or a 9. If the booster in question is B1047, the odds are much better that it’s wrapping up refurbishment and waiting at 39A for CRS-18 to launch before heading to LC-40.

Starlink?

On the other hand, if the booster in question is B1049, it can be all but guaranteed that AMOS-17 will not launch on it, the reason being that – quite literally burned by its last experience with Falcon 9 – Spacecom probably doesn’t want to be the first SpaceX customer to launch on a thrice-flown booster. At the same time, SpaceX is probably exceptionally conscious of the need to ensure mission success and has no interest in adding risk to the AMOS-17 mission profile, no matter how minor.

B1049 launched for the third time in support of SpaceX’s first dedicated Starlink launch on May 23rd, known internally as Starlink v0.9. At this point in time, B1046.3 is believed to be assigned to Crew Dragon’s in-flight abort (IFA) test, expected no earlier than Q4 2019. B1048.3’s status is unknown since the rocket successfully completed its third launch in February 2019. With B1049’s newfound history as the first SpaceX booster to launch on a completely internal mission, it would make a lot of sense for SpaceX to reuse B1049 for the next Starlink mission.

Simultaneously, SpaceX could demonstrate the first launch of a thrice-flown Falcon 9 booster without pushing that risk onto customers, opening up B1048 and future thrice-flown boosters for near-term commercial missions. A step further, this would set SpaceX up perfectly to use internal Starlink missions as full-fidelity demonstrations of booster reuse milestones, going from the four launches to five, six, seven, and beyond.

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.
