SpaceX Starship launch delayed to Tuesday by poor FAA planning
Update: CEO Elon Musk says that SpaceX’s fourth high-altitude Starship launch has been delayed from Monday to Tuesday after an FAA inspector – recently required to be onsite for launches – was inexplicably more than six hours late.
While the smallest grain of salt is warranted given Musk’s recently vitriolic relationship with the FAA, the CEO has every reason not to lie about a federal regulatory agency that SpaceX almost fundamentally depends on. As such, the implication is that a lone FAA inspector – only recently required by the FAA itself to be onsite for SpaceX Starship launches – was somehow more than four or five hours away from Boca Chica, Texas by 11am CDT, March 29th.
The only possible explanation for such a delay is that a single inspector – lacking virtually any of the resources afforded to large government agency – missed a flight on a public airline, had a flight canceled at the last second, or was somehow stranded in the middle of nowhere by car issues. As any sane human familiar with air or car travel would know, those issues happen and should always be anticipated. Knowing full well that it had just changed SpaceX’s Starship launch license just two weeks prior to prevent flights without an inspector present, the FAA does not appear to have prepared for those issues in even the most basic sense, failing to ensure alternate methods of transport or two redundant inspectors.
In essence, due either to severe underfunding, general ineptitude, some childish attempt to assert dominance, or some combination of all three, the FAA has explicitly disrespected the hundreds of (possibly 1000+) SpaceX employees working around the clock for weeks to launch Starship SN11 as quickly as possible. Given that the FAA itself distributed Temporary Flight Restrictions (TFRs) for SN11’s Monday launch on Saturday and noted plans for the launch more than a day prior, the giant regulatory agency had no less than 24-48 hours of prior warning even if they’d somehow ignored or missed SpaceX’s own CEO announcing a delay to March 29th on March 26th.
If a regulatory agency like the FAA is incapable of ensuring that an inspector can stand around at a launch the agency itself required an inspector be present for days prior, the same apparatus assuredly should not and cannot be trusted to regulate systems as complex as modern aircraft, spacecraft, and rockets. If the FAA is, in fact, up to the challenge of responsibly regulating those systems with the public’s best interest in mind, then failing a task as simple as ensuring its own inspector is transported, on time, from Point A to Point B is a conscious decision or mistake. Either way, something clearly needs to change.
CEO Elon Musk says that SpaceX has delayed Starship serial number 11’s (SN11) high-altitude launch debut from Friday to Monday to best ensure that the company can “land & fully recover” the 50-meter-tall steel rocket.
First and foremost, the weekend will allow SpaceX times time for “additional checkouts” and scour Starship SN11 and the data it’s produced during testing for any red flags or minor issues. While plans for a same-day static fire and launch didn’t pan out on Friday, March 26th, SpaceX did manage the first half, firing up just one of Starship’s three Raptors to verify the health of the replacement engine after a Thursday Raptor swap. The test marked the first time SpaceX has intentionally fired up just one of the Raptors installed on a three-engine Starship prototype, so the delay will provide extra time to ensure that all three are still looking good.
Standing down SN11 until probably Monday. Additional checkouts are needed. Doing our best to land & fully recover.— Elon Musk (@elonmusk) March 26, 2021
The weather in Boca Chica, Texas has also taken a turn for the worse in the last few days, so the extra few days will also (hopefully) allow time for wind, visibility, and precipitation conditions to improve. According to Musk, Starship SN11 is now scheduled to fly as early as Monday “afternoon” and, as usual, SpaceX will offer live coverage of the fourth high-altitude launch and landing attempt beginning a few minutes before liftoff.
With a little luck, the Starship prototype will be able to continue a trend of iterative improvement and one-up Starship SN10 with a slightly softer landing and no explosion minutes after touchdown. Stay tuned for updates both here and on SpaceX’s social media platforms to catch the official webcast.

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.”
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:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

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 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 has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
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.
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.
