SpaceX’s Starbase environmental review suffers third delay
The Federal Aviation Administration (FAA) has announced that the completion of a crucial ‘environmental assessment’ SpaceX needs to begin orbital-class Starship launch attempts out of South Texas has been delayed for the third time.
Official known as a programmatic environmental assessment or PEA, the FAA says it started the process in late June 2021 with the goal of verifying that SpaceX’s Starbase orbital launch site (OLS) was mostly benign before the end of 2021. Compared to a regular EA, the programmatic nature of SpaceX’s Starbase review would theoretically allow the company to start small and gradually expand and add new facilities and capabilities without having to restart the arduous review process for each change.
Along those lines, SpaceX’s first draft PEA requested permission for no more than five full-stack Starship launches per year compared to the maximum of 12 Falcon 9 launches or nine Falcon 9 and three Falcon Heavy launches out of Boca Chica that SpaceX had already received permission for from the FAA in 2014.
Unfortunately, even at the time that the start of the process was announced, completing a full PEA in half a year was already unbelievably optimistic. No comparable review, of which there are effectively none, has been completed anywhere close to that quickly. In the face of substantial local opposition, like in the case of Georgia’s Camden Spaceport, even an FAA environmental review for a relatively small rocket launch facility can make little progress after years of tooth-and-nail fighting.
However, the best possible comparison has always been SpaceX’s own environmental assessment for an almost identical orbital-class Starship launch site at Florida’s Kennedy Space Center. Despite the fact that no untouched ground would be broken and even with the apparent might of NASA behind it, it took the FAA and SpaceX about a full year to complete a Pad 39A EA for up to 24 Starship launches per year. As such, the idea that the FAA would be able to complete a PEA for Boca Chica Starship launches in six months was always almost unimaginable.
It should come as no surprise, then, that nine months after SpaceX and the FAA began their Starbase PEA, they appear to be only marginally closer to completing the review. Days before the original December 31st, 2021 deadline, the FAA announced a delay to February 28th, 2022. On February 14th, the FAA announced a second delay to March 28th. Most recently, on March 25th, the FAA announced a third delay to April 29th.
Put simply, the FAA is effectively saying that it is actually further away from completing SpaceX’s South Texas Starship PEA than it was in December 2021. The extraordinarily opaque nature of the process also means that anyone outside of the loop or without internal sources is left to simply guess what is causing those delays or why the FAA keeps pushing the goalposts back just one or two months at a time when it’s unclear that anyone can actually predict when the process will be completed.
Without journalists filing Freedom of Information Act (FOIA) requests, the full extent of public knowledge about what is causing those delays would be the FAA’s scant few statements on the process. The most valuable information provided thus far is that the FAA is “reviewing the Final PEA,” which does seem to imply some degree of progress. Nonetheless, the agency still included a boilerplate statement noting that it’s “completing consultation and coordination with agencies at the local, State, and Federal level,” making it hard to actually say if any progress has been made. In February 2022, the FAA said it was “continuing consultation and coordination with other agencies.”
In December 2021, the FAA stated that it was “continuing consultation and coordination with other agencies at the local, State, and Federal level” while “SpaceX continues to prepare the Final PEA for…FAA review and acceptance.” By using such vague and unspecific language, the FAA makes what little it does say virtually impossible to parse and barely better than nothing. Solely thanks to documents secured through FOIA, we know that the FAA itself may not actually be to blame for most or all of the PEA’s four months of delays.
Instead, the US Department of the Interior (DOI), Fish and Wildlife Services (FWS), and National Park Services (NPS) may be partially responsible through their required coordination with the FAA, which they appear to be taking full advantage of to exert some form of control over the outcome. Bureaucrats are being bureaucratic, in other words.
Outside of email chains and boardrooms, however, it’s no longer clear that completing the PEA and securing an FAA launch license are the limiting factor for the first orbital Starship test flights. SpaceX CEO Elon Musk recently announced that SpaceX is changing the prototypes assigned to the first full-stack launch – likely to Booster 7 and Ship 24. Super Heavy B7 has yet to begin any kind of testing and Starship S24 is still in several pieces, so it’s safe to say that SpaceX’s new pair are months of concerted testing away from launch readiness.
If anything goes wrong during those tests, any significant design issues are discovered, or any damage is caused, it’s entirely possible that what Elon Musk says could take as few as two months will actually take more like four to six. Only time will tell. For now, the FAA likely has a few months before Starship’s South Texas PEA and full-stack launch license truly become the limiting factor for the rocket’s first orbital launch attempt.
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.
Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.
Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.

The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.
The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.
Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.
Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.
Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.
Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.
Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.
The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.
Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
