Update: SpaceX says it and NASA are moving forward with plans to launch a Crew Dragon carrying US, Japanese, and Russian astronauts as early as noon EDT (16:00 UTC) on Wednesday, October 5th.
Concurring with a statement made on October 3rd, SpaceX has also called off a planned October 4th launch of its Starlink 4-29 mission. However, the company has delayed Starlink 4-29 just 24 hours and says that Falcon 9 will launch the latest batch of internet satellites out of California no earlier than (NET) 4:10 pm PDT (23:10 UTC) on October 5th. Intelsat has also confirmed that its Galaxy 33 and Galaxy 34 geostationary communications satellites are scheduled to launch on a Falcon 9 rocket as early as 7:07 pm EDT (23:07 UTC) on October 6th, leaving SpaceX on track to launch three Falcon 9 rockets from three launch pads in 31 hours.
The company achieved a similar feat earlier this year when it launched three Falcon 9 rockets in 36 hours. Three launches in 31 hours would break that record.
SpaceX is on the cusp of launching three Falcon 9 rockets in a handful of days. Minor issues with two of the three missions, however, have complicated the already hard process of coordinating so many launches at the same time.
For many reasons, rocket launches are an inherently difficult thing to schedule, and that difficulty only gets magnified when attempting to launch rockets as quickly as possible for customers with very different needs while using a fixed number of launch pads. SpaceX’s upcoming series of launches demonstrates the slippery nature of high-cadence rocket launch scheduling better than most.
Last month, SpaceX ran into issues (mainly bad weather) that delayed its Starlink 4-34, 4-35, and 4-36 missions by varying degrees. Before those delays, SpaceX had intended to break its LC-40 pad turnaround record with Starlink 4-35 and then repeat the feat with Starlink 4-36, but that opportunity closed when Starlink 4-34’s several weather delays pushed Starlink 4-35 from September 19th to the 24th and raised the risk of the next launch, Starlink 4-36, interfering with customer missions planned in the first half of October.
That burst of customer missions, all of which take priority over SpaceX’s own Starlink missions, meant that a few-day delay for a mission two launches prior ultimately pushed Starlink 4-36 from the end of September to no earlier than October 20th. It will launch out of Cape Canaveral Space Force Station’s (CCSFS) LC-40, the same pad that launched Starlink 4-35 on September 24th and will launch Intelsat’s Galaxy 33 and 34 satellites no earlier than (NET) October 6th and Eutelsat’s Hotbird 13F satellite NET October 13th. All four launches (including Starlink 4-36) are thus contingent upon each other, so a delay with one mission would likely delay each subsequent mission to leave enough time for pad turnaround and rocket processing.
Date Mission Rocket Location Pad 10/04/22 Starlink 4-29 Falcon 9 California VSFB SLC-4E 10/04/22 SES-20/21 Atlas V Florida CCSFS LC-41 10/05/22 Crew-5 Falcon 9 Florida KSC LC-39A 10/06/22 Galaxy 33/34 Falcon 9 Florida CCSFS LC-40 10/13/22 Hotbird 13F Falcon 9 Florida CCSFS LC-40 10/20/22 Starlink 4-36 Falcon 9 Florida CCSFS LC-40
SpaceX isn’t the only company that launches out of Cape Canaveral, Florida. Originally scheduled in late September, the United Launch Alliance’s (ULA) Atlas V launch of the SES-20 and SES-21 geostationary communication satellites was delayed by the same weather system that indirectly hampered Starlink 4-35 and 4-36. That mission is now set to launch NET 5:36 pm EDT (21:36 UTC) on October 4th.
Up first, however, is SpaceX’s Starlink 4-29 mission out of California’s Vandenberg Space Force Base (VSFB). Delayed to October 4th hours before its October 3rd target, the new schedule will give SpaceX “more time for pre-launch checkouts,” Falcon 9 will now lift off as early as 4:48 pm PDT (23:48 UTC), a little over two hours after Atlas V. However, making the whole situation even more interlinked, SpaceX says it will stand down from its October 4th Starlink launch attempt if its next Florida mission – Crew Dragon’s fifth operational NASA astronaut launch – remains on track for its current noon EDT (16:00 UTC), October 5th launch target.
In an October 3rd briefing following a mostly clean launch readiness review (LRR), NASA and SpaceX officials revealed that three new minor issues – “not showstoppers” – had appeared after a busy period of ground testing. An otherwise successful astronaut dry dress rehearsal and a subsequent wet dress rehearsal and static fire uncovered a possible fire extinguisher leak in the Dragon spacecraft and a minor issue with one of the Falcon 9 rocket booster’s nine Merlin 1D engines. A communications issue was also discovered on the SpaceX drone ship Crew-5’s rocket booster is meant to land on in the Atlantic Ocean.
SpaceX and NASA officials weren’t especially worried about the issues and were confident they would be resolved in time for an October 5th launch. If they aren’t and Crew-5 slips to October 6th, SpaceX should be able to launch Starlink 4-29 on October 4th, but then it’s unclear if the company will also be able to launch Intelsat’s Galaxy 33 and Galaxy 34 geostationary communications satellites on the same day as Crew-5. Galaxy 33/34 is scheduled to launch NET 7:07 pm EDT on October 6th, likely ~6 hours after Crew-5’s own October 6th launch window.
If Crew-5 slips and Galaxy 33/34 can’t launch on the same day, it would likely delay both Hotbird 13F and Starlink 4-36. It’s also unclear if Starlink 4-29 can launch on the same day as Crew-5 if it flies after Dragon. Either way, SpaceX could potentially end up launching Crew-5, Galaxy 33/34, and Starlink 4-29 on October 5th and 6th – potentially less than a day and a half apart.
As SpaceX continues to push the limits of what is possible with its existing Falcon launch and landing infrastructure, chaotic scheduling situations like this, where small issues impact large strings of launches, will become the norm instead of the exception
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.
🚨 Tesla has just expanded its Robotaxi geofence in Houston
It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u
— TESLARATI (@Teslarati) October 26, 2026
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.
