Reading between the lines, the US Air Force has effectively confirmed that GPS III Space Vehicle 03 (SV03) – the third GPS III satellite built by Lockheed Martin – is ready for launch aboard a SpaceX Falcon 9 rocket, scheduled no earlier than December 2019.

In December 2018, SpaceX successfully launched the first GPS III spacecraft aboard an expendable Falcon 9 Block 5 rocket, kicking off a launch campaign – shared between SpaceX and ULA – that will likely last until 2023 or 2024. Thus far, ULA has won a single GPS III launch contract, scheduled for July 2019, while SpaceX has won three (with options for two more). Thanks to competition forcefully reintroduced by a 2014 SpaceX lawsuit, the USAF – and thus US taxpayers – are likely saving a minimum of $50M per GPS III launch.

In late 2018, SpaceX’s closer followers were surprised to discover that brand new Falcon 9 Block 5 booster B1054 – the first to be officially certified for a critical operational military launch – was to be expended, making no attempt to land. This was confusing for several reasons.

“If Falcon 9 [was to be] expended solely because of mission performance requirements, despite the oddly low payload mass (~3800 kg) and comparatively low-energy orbit (~20,000 km), the only possible explanation for no attempted recovery would be the need for Falcon 9’s upper stage to circularize the orbit after a long coast. However, the mission parameters the USAF shopped around for would have placed the GPS III satellite into an elliptical orbit of 1000 km by 20,181 km, an orbit that would almost without a doubt leave Falcon 9 with enough propellant for a drone ship recovery.”

As it turns out, there was, in fact, nothing unique about the elliptical, medium-energy orbit GPS III SV01 was placed in. According to external analysis of the Falcon 9 upper stage’s final deorbit activities, SpaceX had “plenty of extra performance available”, objectively indicating that that excess performance was intentionally removed from booster B1054 at the cost of its ability to land. The (unconfirmed) reason for this is quite simple: the US Air Force chose extreme – perhaps even excessive – caution to account for the minute chance that myriad failures might happen mid-launch.

To sacrifice, or not to sacrifice

According to a USAF statement made in mid-May, GPS III Space Vehicle 03 (SV03) has been officially classed as “available for launch”, jargon that means the satellite is fully assembled and has successfully completed extensive pre-launch testing. For SpaceX’s inaugural GPS III launch (SV01), a pathfinder that carried unique wait and likely took additional processing time, SpaceX and the USAF took roughly five months to go from shipping the satellite to Florida to going vertical atop Falcon 9. More likely than not, GPS III SV03 has already begun to be prepared for transport from California to Florida, meaning that SV03 is roughly 1-2 months ahead of the schedule SV01 followed ahead of its Falcon 9 launch debut.

So: the GPS III satellite is ready for launch. The next critical milestones will be the satellite’s transport to Florida and SpaceX’s completion of the mission’s USAF-grade Falcon 9. B1054’s technically unnecessary sacrifice thus raises a question for SpaceX’s next GPS III launch, currently scheduled no earlier than December 2018: will another fresh Falcon 9 Block 5 booster be sacrificed to the gods of Obsessively Cautious Margins?

The optimist in me wants to say, “Of course!” With GPS III SV01, SpaceX perfectly demonstrated Falcon 9’s performance and permitted the USAF the luxury of expending a brand new Falcon 9 booster to satisfy the customer’s desire for extremely cautious margins. The Falcon 9 upper stage’s luxuriously expensive (in terms of delta V) deorbit burns – performed after a several-hour cost in orbit – served as another definitive demonstration of the rocket’s intentionally underutilized performance. Having demonstrated a flawless launch with margins on margins, it seems reasonable that the US Air Force would permit SpaceX the freedom to recover Falcon 9 B105x after launching GPS III SV03.

On the other hand, the USAF and Department of Defense are not exactly known for their rational, evidence-based strategies of decision-making and procurement. As such, it’s safe to say that – without official info from SpaceX or the USAF – the answer to the question of whether SpaceX will need to continue expending valuable boosters for GPS launches is entirely up in the air – call it a 50-50 split.

In the meantime, GPS III SV03’s Falcon 9 booster is likely several months away from shipping off to SpaceX’s McGregor, Texas facilities for static fire testing. Up next for SpaceX is a critical Falcon Heavy launch that could secure the rocket’s certification for US military launches, become the first USAF mission to utilize flight-proven SpaceX boosters, and pave the way for the USAF to develop a dedicated certification process for launching on commercially-developed reusable rockets.

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.
