Roughly 24 hours before SpaceX CEO Elon Musk was scheduled to present an update on the company’s Starship launch vehicle development, NASA administrator Jim Bridenstine tweeted a bizarre and wholly unprovoked statement on the subject.

Seemingly equating SpaceX’s recent Crew Dragon delays with the distribution of Elon Musk’s public attention, the NASA administrator’s comment was almost universally criticized by the spaceflight community at large – and rightfully so.

https://twitter.com/JimBridenstine/status/1177711106300747777

First, some context. Created in 2010 and first supported with serious funding some 12-24 months later, NASA’s Commercial Crew Program (CCP) exists to replace the astronaut transport capabilities once offered by Space Shuttle and now achieved with contracts for seats on Russian Soyuz launches. Primarily the result of inept bureaucracy in NASA and Congress, the Space Shuttle was “retired” in 2011 in full knowledge that the US would have to rely on Russia to get NASA astronauts to the ISS until 2015 (at the absolute earliest).

Congress shut down multiple 2010 proposals to continue Shuttle flights until the late 2010s, choosing instead to kill the Shuttle and divert its associated funding to the expendable Ares V rocket (now the Space Launch System, SLS) and Orion crew capsule. More on that later...

Retweeted by Bridenstine’s official Twitter account, above is the absolute best-case interpretation of the NASA administrator’s comment. Although Eric Berger means well, the interpretation gives NASA far too much credit. Specifically, Bridenstine (or whoever fed him the statement) went out of his way to make it entirely one-sided in its focus on SpaceX. By all appearances, it would have never been posted if not for Elon Musk’s plans to present on Starship. Bridenstine additionally notes that “Commercial Crew is years behind schedule” and indicates that “NASA expects to see the same level of enthusiasm focused on [its] investments”.

Altogether, it’s simply impossible to interpret it as anything less than Bridenstine scolding SpaceX – and SpaceX alone – for not falling to the floor, kissing NASA’s feet, and pretending that Crew Dragon and Falcon 9 are the only things in existence. Absent from Bridenstine’s criticism was NASA’s other (and even more delay-complicit) Commercial Crew Partner, Boeing, who has yet to complete a pad abort or orbital flight test of its Starliner spacecraft. SpaceX completed Crew Dragon’s pad abort in 2015 and completed a flawless orbital flight test in March 2019.

In essence, Bridenstine is publicly implying that SpaceX needs to stop being (or appearing to be) distracted by Starship and focus 100% on Crew Dragon. Boeing was not mentioned, despite being a minimum of six months behind SpaceX and dramatically more ‘distracted’ in the Bridenstine-style interpretation of the word. For reference, Boeing is a publicly-traded company with 150,000 employees, annual revenue of more than $100B, and a market cap of $206B. Boeing has 14 subsidiaries, a handful of which are involved in spaceflight, and has no less than one or two dozen products that are each more fiscally important to shareholders and board members than Starliner.

Compared to Boeing’s annual ~$100B revenue, the entirety of the Starliner development program – from the drawing board in 2010 to crewed, orbital spaceflight sometime in 2020 – is ~$4.8B. On the scale of corporate focus, Starliner has likely been a blip at most in 2019, with the company probably far more focused on the systematic organizational failures that lead to the deaths of hundreds of people in two near-identical 737 MAX crashes. Alas, NASA administrator Jim Bridenstine did not release a statement publicly implying that Boeing needs to devote the “same level of enthusiasm” to Starliner after the second fatal 737 MAX crash in March 2019. Nor did Bridenstine release a statement charging Boeing with a lack of focus after continuous reports of issues with the company’s KC-46 Pegasus tanker program, nor Boeing’s recent $9.2B US Air Force trainer jet contract, or myriad other corporate focuses.

A Boeing Starliner test article prepares for thermal vacuum (TVac) testing in January 2019. Starliner’s uncrewed orbital flight test (OFT) – comparable to Crew Dragon’s March 2019 DM-1 launch – is unlikely to occur until November or December 2019. (NASA)

On the other hand, as Musk noted in his relatively subtle September 28th responses to Bridenstine’s implicitly derisive comment, something like 50-80% of the entirety of SpaceX’s workforce and resources are focused on Crew Dragon, the Falcon 9 rockets that will launch it, or a combination of both. At present, Starship is – at most – a side project, even if its strategic importance to SpaceX is hard to exaggerate. The same is largely true for Starlink, SpaceX’s ambitious internet satellite constellation program. It may be true that Starship will eventually make Crew and Cargo Dragon (as well as Falcon 9 and Falcon Heavy) wholly redundant, but that is likely years away and SpaceX will support NASA – as it is contractually required to – for as long as the space agency has vested interest in using Crew Dragon.

At the same time, NASA has explicitly and publicly chosen to prioritize safety over schedule with the Commercial Crew Program, accepting the possibility of delays and cost overruns to ensure that SpaceX and Boeing can build the safest spacecraft possible.

In a September 28th interview with CNN, Musk bluntly noted that the hardware was – at this point in time – more or less ready for flight and will be on-site at SpaceX’s Pad 39A Florida launch site within the next two months. According to Musk, from then on, any additional launch delays can almost entirely be attributed to the paperwork and reviews NASA must complete before giving SpaceX the go-ahead. If Bridenstine wants SpaceX to launch astronauts sooner, one – and possibly the only – solution is to tackle the roadblocks created by NASA’s own self-enforced red tape. The question, then, is whether Bridenstine wants to cut away red tape that may (or may not) be there for good reason.

When the pot calls the kettle black

Detached from whining about a contractor’s CEO presenting about a non-NASA program, complaining about Commercial Crew delays is at least slightly more reasonable. Originally intended to launch as early as 2015, Congress systematically underfunded the Commercial Crew Program by more than 50% for over half a decade, dispersing $2.4B of the $5.8B NASA requested from 2011 to 2016. Unsurprisingly, this completely upended Boeing and SpaceX development schedules. By September 2014, SpaceX aimed to have Crew Dragon certified by NASA for astronaut transport before the end of 2017, but even then, NASA already saw that schedule as overly optimistic.

It would be another two years before Congress began to seriously fund Commercial Crew at its requested levels, beginning in FY2016. In response to Bridenstine, former NASA deputy administrator Lori Garver noted that over the ~5 years Congress consistently withheld hundreds of millions of dollars of critical funds from Commercial Crew, NASA’s SLS rocket and Orion spacecraft were just as consistently overfunded above and beyond their budget requests. From 2011 to 2016 alone, SLS and Orion programs requested $11B and received an incredible $16.3B (148%) from Congress, while Commercial Crew requested $5.8B and received $2.4B (41%).

Ironically, despite literally receiving almost seven times as much funding as Crew Dragon and Starliner, SLS and Orion are arguably just as – if not more – delayed than their commercial brethren. Originally intended to launch an uncrewed test flight in 2017, there is now little to no chance that that mission (known then as EM-1 and now as Artemis-1) will launch before 2022, a delay of roughly half a decade. The cost of the SLS/Orion program recently crested $30B, a figure likely to grow to ~$40B before it has conducted a single launch. Of that funding, approximately a third has gone to Boeing, the primary contractor responsible for NASA’s comically-delayed SLS Core Stage – the orange booster pictured above.

The Commercial Crew development program will likely cost NASA $8B total over 9-10 years and produce two clean-sheet, high-performance, (relatively) low-cost crewed spacecraft. After their demonstration launches are completed, NASA will transition to fixed-price service contracts with SpaceX and Boeing to routinely send astronauts to the ISS several times per year.

Put simply, if Bridenstine actually cared about defending “the investments of the American taxpayer” more than wielding their sanctity as a political weapon, he wouldn’t have folded like a house of cards at the slightest resistance to his attempts to cull SLS/Orion delays and cost overruns, and he certainly wouldn’t be wasting breath complaining about what SpaceX’s CEO is or isn’t talking about.

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

on

Credit: SpaceX

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.
