SpaceX to shift Falcon 9’s next West Coast launch to Florida, the first of its kind in decades
According to NASASpaceflight spaceflight reporter Michael Baylor and an Argentinian government website, SpaceX appears to have decided to move its next West Coast launch from California to Florida, signifying the first East Coast polar launch in half a century could be just four months away.
Initially expected to launch out of SpaceX’s Vandenberg Air Force Base (VAFB) SLC-4E pad on a Falcon 9 rocket, the Argentinian space agency’s (CONAE) SAOCOM-1B Earth observation satellite was scheduled to lift off no earlier than February 2020. That launch window remains the same but Florida’s Cape Canaveral Air Force Station (CCAFS) has somehow arranged approval to reopen the United States’ Eastern polar launch corridor. The story behind the corridor’s closure is a bizarre one.
Having earned itself a bit of notoriety and fame over the years, the story of the closure of the Eastern polar launch corridor is simple on the outset. In November 1960, a Thor Able-Star rocket lifted off from Cape Canaveral for what was hoped to be a routine military launch. This particular mission carried GRAB II, a covert signals intelligence spacecraft designed to spy on radio communications around the globe.
Long story short: that Thor rocket suffered a failure that caused the booster to prematurely shut down and divert from its planned trajectory, forcing the range safety officer to manually trigger the rocket’s self-destruct mechanisms. Broken apart by explosives, one unlucky cow – standing in a Cuban field some 400 miles (650 km) downrange – was struck by rocket debris, killing the farm animal. Indeed, this might initially seem like an absurd reason to entirely end the practice of polar orbital launches from Cape Canaveral, but Cold War tensions were extremely high and President Fidel Castro leaped on the opportunity to hound the US.
An article published in a 2008 issue of the US Naval History Magazine covers this minor debacle in greater detail, shedding some much-needed light on why things played out how they did.
“In what somewhat inaccurately became known as “the herd shot around the world,” some of the falling rocket debris apparently splattered on a Cuban farm and killed a cow. “This is a Yankee provocation,” accused Revolucion, an official Cuban publication, insisting that the rocket was deliberately exploded over the country. Government radio stations cited the incident as further proof that the United States was trying to destroy the regime of Cuban President Fidel Castro. One cow was even paraded in front of the U.S. Embassy in Havana wearing a placard reading “Eisenhower, you murdered one of my sisters.”
Castro filed a complaint at the United Nations, and Washington sheepishly conceded the possibility that “fragments from the rocket booster” could have landed in Cuba. CIA Director George Tenet later quipped somewhat tastelessly that it was “the first, and last, time that a satellite had been used in the production of ground beef.” Further launches overflying Cuba were postponed, and improvements were made to the Cape Canaveral range-safety system. In any case, it was a dejected NRL group that returned to Washington.”

That overflight postponement was never withdrawn and VAFB – located on the coast of California – has supported all US polar launch** activity since late-1960. Public word of the possible reopening of the Eastern polar launch corridor came 57 years later when Wayne Monteith, commander of the 45th Space Wing, revealed that he had tasked analysts to determine whether the corridor could be reopened in light of wildfire troubles that closed VAFB’s Western Range in 2016. They concluded that there were no obvious technical showstoppers.
**There is a report that a Thor Delta C rocket performed two sun synchronous orbit (SSO; ‘nearly polar’) launches in the mid-1960s, overflying Cuba in the process, but it’s unclear if the trajectory used was the same as those used before Thor’s 1960 GRAB II failure.
A reporter who was present at the press conference said that SpaceX’s SAOCOM 1B launch hadn’t officially been put on on the Eastern Range’s planning schedule, indicating that some work remains before it can truly be said that the Eastern polar launch corridor has been reopened. Nevertheless, Douglas Schiess, the current commander of the 45th Space Wing, was obviously confident that those final steps are more technicalities than potential showstoppers and that 21st-century Eastern polar launches are now a question of “when”, not “if”.
In Monteith’s 2017 statement, it was stated that there is one major condition on the reopening: all launch vehicles intending to fly it must feature autonomous flight termination systems (AFTS). This is due to the risk that the rocket’s plume might prevent the reliable reception of radio telemetry at Florida-based tracking stations. SpaceX is currently the only launch provider in the world to have implemented AFTS and is thus the only provider currently capable of launching polar missions from Florida.
Time will tell just how extensive Florida’s polar launch capabilities are and how dramatically the new capability will impact Vandenberg’s commercial launch ecosystem. Speaking in 2017, Monteith was fairly blunt in his assessment that California was not only tepid on the subject of expanding VAFB’s commercial launch manifest, but was actively hostile at points. His point: if Vandenberg isn’t going to put effort into stimulating a commercial polar launch ecosystem, Cape Canaveral might as well try.
VAFB is currently in the throes of a four-month launch lull previously expected to last until SpaceX’s Feb. 2020 SAOCOM 1B launch. Depending on how things play out for startup Firefly Aerospace and how readily CCAFS can take to its new polar launch role, Vandenberg’s lull could easily stretch into the second half of 2020, perhaps more than a year between launches.

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.

It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u

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.
