Speaking on September 28th, SpaceX CEO Elon Musk sketched out a fairly detailed picture of Starship’s path to orbit, from the first flight of the first full-scale prototype to the spacecraft’s inaugural orbital launch atop a Super Heavy booster.

Incredibly, Musk was persistent with claims that he has challenged SpaceX’s Starship teams to conduct the next-generation rocket’s first orbital launch within six months, drawing a line in the sand around April 1st, 2020 (?). How, then, does the SpaceX CEO foresee the next year or so playing out?

A whole lotta ‘Ships

As is the company’s signature, Musk confirmed that the Starship development program will continue to be highly distributed, hardware-rich, and focused on an iterative and continuous process of learning by doing. Starhopper is perhaps the best emblem of this methodology, defying almost every conceivable aerospace industry norm to successfully build and repeatedly fly what was essentially a rocket built outside by water tower welders.

Starhopper may have scarcely been meant to fly at all, serving almost entirely as a proof of concept and learning experience, but Musk strongly suggested that future Starship prototypes will replicate its highly iterative, learning-on-the-job approach to development. In short, much like SpaceX has nearly completed Starship Mk1 (and Mk2) from scratch in less than six months, SpaceX’s development strategy involves building a lot of Starship prototypes as quickly as possible.

Specifically, Elon Musk stated – in his opinion – that SpaceX will likely attempt its first orbital Starship-Super Heavy launch immediately after Starship Mk1’s first flight attempt, a suborbital launch to ~20 km (12.5 mi). Assuming that test – far more critical than any of Starhopper’s travails – is successful, the very next Starship flight could be an orbital launch attempt.

First and foremost, Musk was pretty clear that the rough schedule he laid out was a “stream of consciousness”. Indeed, the eccentric CEO contradicted (or updated) himself over the course of answering the same question, stating that “[SpaceX] would fly to orbit with [Starship] Mk3” before saying that that it would actually be “Mk4 or Mk5”. Musk is still undoubtedly set on announcing gobsmackingly ambitious schedules for his projects, but it’s worth noting just how serious he seemed while discussing Starship’s development timeline.

He noted that SpaceX will likely “have [Starship] Mk2 built within a couple of months – or less”, referring to the second prototype currently in the late stages of integration at the company’s similar Cocoa, FL facilities. Additionally, Musk indicated that Starship Mk3 – yet to begin construction in Boca Chica – could be finished as few three months from now (around the start of 2020), with Starship Mk4 – to be built in Florida – could be just one to two months behind (NET Feb/March 2020). Correcting his previous statement, whether intentional or not, Musk also added that SpaceX’s first orbital Starship launch attempt would likely involve either the Mk4 or Mk5 prototype and occur “less than six months from now”.

As a slight consolation to the eyewateringly ambitious timeline he laid out, Musk qualified his “six months to orbit” target by acknowledging that it would only be achievable “provided the rate of design and manufacturing improvement continues to be exponential”. If that remains the case, as he believes it has been over the last six or so months, then SpaceX could be ready for the first orbital Starship launch attempt as few as 6-9 months from now – sometime in the first half of 2020.

A lot will undoubtedly have to go very right for that to remain anywhere within the realm of plausibility. This includes the rapid maturation of Starship’s Raptor engine and vacuum-optimized variant, the successful completion of Starship Mk1’s 20km flight test, the assembly and static fire of the first Super Heavy booster(s), the construction of brand new orbital launch facilities, and the FAA’s approval of all aforementioned flight operations.

Needless to say, the odds are heavily stacked against Musk’s goal of reaching orbit within six months. There is undoubtedly a chance that SpaceX can pull it off, even if success would essentially involve constructing a bridge while driving off a cliff. However, the most important thing to note is that even if Elon Musk is a factor of 1.5, 2, 3, or even 4 times off and Starship reaches orbit for the first time 12 or 18 or 24 months from now, it will still have been an incredibly brisk period of development for a rocket as large, high-performance, and ambitious as Starship/Super Heavy.

It should also be made clear that, while it’s utterly beyond the present capabilities of NASA and other space agencies/companies of the 21st century, Saturn V went from paper to its first orbital launch in just five years. Depending on how one perceives Starship development, it could be said that SpaceX began development – particularly marked by Raptor engine prototype testing – as early as 2016. Suffice it to say that it’s far from impossible that Starship’s first orbital launch will happen next year, even if the challenges SpaceX faces are immense.

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

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.
