SpaceX Falcon 9 rocket nails first operational NASA astronaut launch [updated]
Update: SpaceX has successfully resolved a handful of minor thermal control issues facing the brand new Crew Dragon capsule currently ferrying four astronauts in low Earth orbit (LEO).
As previously noted, shortly after the spacecraft reached orbit, two redundant thermal control system pumps registered pressure spikes, pushing Crew Dragon to use the backup pump. SpaceX was able to resolve that issue, effectively restarting the pumps and confirming healthy operation. Several hours later, the backup pump (“Loop B”) suffered another minor issue but was again returned to healthy operations. Simultaneously, Crew-1 astronauts found themselves stuck at an (admittedly comfortable) cabin temperature of 23C (~73F).
More pressingly, three of four heaters used to warm the propellant fed to Crew Dragon’s small Draco maneuvering and attitude control thrusters were automatically disabled a few hours after liftoff. Essential for most operations in orbit and necessary for Dragon to be allowed to remain docked with the ISS, restoring the functionality of at least one of the three heaters was essential, and SpaceX was thankfully able to restore function to all three by relaxing excessively conservative limits in the spacecraft’s flight software. Thanks to SpaceX’s fast work, Dragon is now in perfect health and ready for two crucial Draco burns at 11:20 am and 12 pm EST (UTC-5) on Monday, November 16th and is still scheduled to arrive at the ISS around 11 pm EST.
Right on schedule, a SpaceX Falcon 9 rocket has successfully lifted off on the company’s operational NASA astronaut launch debut, sending four crew members on their way to the International Space Station (ISS) in a historic moment for commercial spaceflight.
Days prior, NASA and SpaceX completed a multi-day “flight readiness review (FRR),” the results of which made SpaceX the first private company in human history to be qualified by a national space agency for routine astronaut launches. As is now more or less routine, the SpaceX Falcon 9 rocket assigned to NASA’s Crew-1 mission performed flawlessly over the 12 minutes it was involved in the launch, including nominal booster and upper stage performance, a successful booster landing at sea, and a smooth Dragon deployment from Falcon 9’s expendable second stage.
In a small point of concern, Crew Dragon capsule C207 (colloquially named Dragon Resilience by its crew) appeared to suffer a minor hardware or software fault shortly after orbital insertion, offering the first public glimpse behind the scenes as ground teams coordinated with Dragon’s orbiting astronaut crew to diagnose and fix the issue.
According to information revealed by SpaceX and NASA officials as they interacted with Crew-1 NASA astronauts Mike Hopkins, Victor Glover, Shannon Walker, and Japanese (JAXA) astronaut Soichi Noguchi, Crew Dragon’s fault detection software was tripped sometime after reaching orbit. Both thermal control system (TCS) “loop” pumps – likely referring to pumps used to circulate a liquid-based radiator system to maintain capsule temperature – experienced off-nominal pressure spikes, causing the spacecraft computer to switch to the second pump (“Loop B”).
As SpaceX’s main earth-to-ground communications team member (CapCom) noted, the TCS pump issue was far from critical given that both pumps appeared to be healthy – and one of those two redundant pumps functioning healthily – moments after Dragon alerted its passengers to the issue. Deemed to be not a showstopper, SpaceX continued the mission and permitted Crew Dragon to begin its first orbit-raising thruster burn – the first of a fairly complex series of ‘phasing’ burns needed to safely rendezvous with the International Space Station (ISS).
Unfortunately, due to a 24-hour weather delay from November 14th to November 15th, the complexities of orbital rendezvous mean that Crew Dragon’s Crew-1 mission to the ISS will involve a roughly day-long cruise phase. Had SpaceX been able to launch on the 14th, the cruise phase would have been just 8.5 hours long – perhaps the fastest crewed US space station rendezvous ever. Crew-1 will thus align quite closely with SpaceX’s Demo-2 astronaut launch debut, although likely not interspersed with manual astronaut piloting tests this time around.
On top of Crew Dragon’s thus far successful performance, Falcon 9 also completed a task critical for future Crew Dragon launches when new booster B1061 safely landed aboard SpaceX drone ship Of Course I Still Love You (OCISLY). While normally a distinctly secondary objective, booster recovery was all but essential for SpaceX and NASA during the Crew-1 launch after NASA’s recent reveal that B1061 has been assigned to launch Crew-2 as early as March 31st, 2021. In the likely event that the Falcon 9 booster is in good condition and NASA signs off after shadowing SpaceX’s refurbishment process, SpaceX will also become the first private company in history to launch astronauts into orbit on a flight-proven rocket booster. Additionally, thanks to plans to reuse Crew Dragon capsule C206 of Demo-2 fame, Crew-2 will also mark the first time in history that US astronauts launch into orbit in a reused space capsule.
If the Crew-1 cruise phases goes according to plan, Crew Dragon will autonomously ferry Hopkins, Glover, Walker, and Noguchi from a ~200 km (~125 mi) parking orbit to the International Space Station (ISS) between now and Monday, November 16th, nominally docking with the space station around 11 pm EST (04:00 UTC 17 Nov). From liftoff to reentry, Crew-1 is expected to be the longest continuous spaceflight of a US spacecraft in American history, spending approximately six months in orbit. For JAXA astronaut Soichi Noguchi, his Crew-1 launch also made him the third astronaut in human history to fly to orbit on three separate vehicles.
Ultimately, for SpaceX, the company has never been closer to achieving its foundational goal of enabling the affordable expansion of humanity into space than it is after today’s successful Crew-1 launch.
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.
