SpaceX’s Starbase environmental review is inches from the finish line
Update: Just two days after the FAA’s latest delay announcement, an online portal documenting SpaceX’s Starbase environmental assessment progress has been updated to show that the last step requiring “interagency consultations” was completed on June 2nd.
In theory, that means that to successfully complete its Programmatic Environmental Assessment (PEA) for orbital Starship launches, SpaceX merely needs to incorporate all recommendations, requirements, or mitigations added during the interagency review process into one final draft and presumably secure the approval of all relevant stakeholders one last time. Once those documents are complete, approved, and published, all Starbase will need to begin orbital Starship test flights is an FAA launch license.
Securing that launch license is its own can of worms with plenty of unique challenges, but it’s highly unlikely that SpaceX and the FAA won’t be able to come to some kind of agreement allowing the company to begin those test flights within a month or two of receiving a good environmental review. According to the FAA, the final results of the Starbase PEA are scheduled to be released on June 13th.
The US Federal Aviation Administration says that its environmental review of SpaceX’s plan to conduct orbital Starship launches out of South Texas has been delayed for the fifth time in five months.
However, despite the chronic delays and the FAA’s odd decision to announce a new delay every month instead of simply acknowledging that it doesn’t know when the process will be finished, there are now even more reasons to expect a positive outcome.
Even though there were attempts to spin the new information into something negative, a document acquired through the Freedom Of Information Act (FOIA) by Bloomberg revealed that the US Fish and Wildlife Service (FWS) had decided to approve its portion of the Starbase environmental review. Their only condition: that SpaceX implement a few small mitigation measures, “including contracting with a qualified biologist to conduct monitoring of vegetation and birds, operating an employee shuttle between the launch facility site and nearby town of Brownsville, reducing vehicle traffic, and adjusting lights to minimize the impact on sea turtles.” Bloomberg chose not to publish the documents it received through the FOIA process.
In the same set of documents, the FWS also revealed that SpaceX has removed a request for permission to build a small desalination plant, a natural gas production and liquefaction plant, and a natural gas power plant at or near Starbase’s launch site from Starbase’s first Programmatic Environmental Assessment (PEA). That change comes as little surprise. In fact, SpaceX’s decision to pursue a “programmatic” assessment instead of a more common standalone assessment means that the company will be able to pursue additions to a basic Starbase environmental approval without having to rebuild the foundation each time.
In this case, a “basic approval” would mean the ability to conduct at least a few orbital Starship launches per year. Once that foundation is secured, SpaceX should be able to tier new environmental assessments on top of it and pursue permission for a desalination plant, natural gas production, more annual launches, or any other additions that might benefit Starbase. The simpler the foundation, the harder it should be for environmental stakeholders and agencies to protest or prevent SpaceX from receiving a good outcome.
“The FAA now plans to release the Final PEA on June 13, 2022 to account for ongoing interagency consultations concerning Section 4(f) of the Department of Transportation Act. All other consultations and analysis have been completed at this time.”
Another cause for optimism: after four delays of one or two months, the FAA’s latest delay announcement only pushes the conclusion of the review from May 31st to June 13th. Additionally, the FAA confirmed that only one small component of the entire review remains unfinished. Every other major component has been completed successfully and will likely result in a Finding Of No Significant Impact (FONSI) or Mitigated FONSI that would greenlight the environmental side of conducting orbital Starship launches out of Boca Chica, Texas.
When the draft PEA was first published, the FAA noted several points of contention over Section 4(f) compliance, which is designed to “protect significant publicly owned public parks, recreation areas, and wildlife and waterfowl refuges, as well as significant historic sites, whether they are publicly or privately owned.” At the time, the main problem was SpaceX’s request to close the public Boca Chica Beach and the only highway to it for up to 500 hours (~42 days), as well as a contingency that would allow for another 300 hours of closures to safely respond to emergencies.
Thanks to an even more in-depth environmental impact statement (EIS) completed in 2014 for a Falcon 9 and Falcon Heavy launch pad where Starship’s launch site now stands, we know that SpaceX has already met Section 4(f) demands with a plan for up to 180 hours of road closures per year. In the absolute worst-case scenario, SpaceX should be able to drastically reduce its road closure request to satisfy the Department of Transportation. Subsisting on roughly 20-30 days of closures per year would undoubtedly maim Starbase’s utility but it would at least allow SpaceX to conduct a few basic orbital test flights and some limited ground testing while it rapidly redirects most of its effort to finishing alternative Starship production and launch facilities in Florida.
Regardless, it’s now quite likely that SpaceX’s Starbase environmental review will finally be over by the end of June, freeing up the FAA and SpaceX to focus fully on the launch license side of the equation. Meanwhile, SpaceX still has weeks or even months of work ahead of it to prepare a Starship and Super Heavy pair for their first orbital launch attempt, so (for now) there is no risk of the company being forced to sit around and wait for the gears of bureaucracy to turn.

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.

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady
