SpaceX Falcon Heavy testing delayed after government shutdown
As the U.S. Senate’s majority party searches for ten additional votes in order to end a federal government shutdown that began late Saturday, all “non-essential” activities at the country’s numerous government-operated space launch facilities have ground to an immediate halt and will remain in limbo until a funding bill compromise is hammered out.
While SpaceX is a wholly private space launch company, it relies almost unilaterally upon launch support and range expertise provided by NASA and the US Air Force, both in Cape Canaveral, FL and Vandenberg, CA. Sadly, the Air Force personnel SpaceX depend upon to conduct launches, static fires, and other ignition tests at its launch pads are not considered “essential” under regulations that prevent the federal government from coming to a complete halt in the event of a funding-related shutdown.
Unfortunately, a budget agreement wasn't reached, resulting in a gov't shutdown. This will unfortunately disrupt the lives and operations here at Patrick AFB. Go to https://t.co/yvmNBH1LMy for info on the current shutdown, impact on base resources, & financial resource options.

SpaceX did appear to complete the most thorough round of Falcon Heavy testing yet late Saturday evening, the US Senate’s failure to either pass a continuing resolution or a new funding bill for the fiscal year led to a complete federal government shutdown soon after. As a result, nearly all of the US Air Force’s 45th Space Wing – a crucial backbone of East coast range and launch operations – was furloughed indefinitely, pending new funding from Congress. SpaceX had previously requested a new static fire date for Falcon Heavy on Monday, January 22 (today), a date that is now clearly going to move right for at least as long as the government lacks funding for basic launch operations.
Thankfully, activities like the extensive propellant loading tests that occurred on Saturday night do not technically require range support, so long as no engine ignition or static fire components are included. In the event of a catastrophic failure, the government-run range would be tasked with ensuring the safety of those in the vicinity and coordinating the emergency response that would immediately follow. This policy is brought somewhat into question by the failure of Amos-6 – although that Falcon 9 was being prepared for a static fire test, its highly-destructive failure is understood to have occurred at least five or more minutes before the planned point of ignition. Nevertheless, SpaceX will be able to continue some level of testing with Falcon Heavy, if needed.
Elsewhere, instability
While SpaceX’s Falcon Heavy has undoubtedly garnered magnitudes more eyeballs than the company’s Falcon 9 activities, the government shutdown could be far more consequential for SpaceX’s customers if it cannot be halted within a handful of days. A federal shutdown lasting several days is a hugely disruptive and damaging event on its own, lack of range support on the East coast could quickly begin to eat into SpaceX’s GovSat-1 preparations, the launch of which is targeting NET late January/January 30. For GovSat-1’s flight-proven booster, a static fire at the launch site is unlikely to be bypassed (SpaceX has never skipped a prelaunch static fire), and would typically occur no fewer than four or five days before launch. As a result, in the somewhat unlikely event that the shutdown stretches beyond the next several days, SpaceX customers SES and GovSat could see their launch delayed, an event that would likely bring financial consequences to the public-private satellite venture.
Looking slightly farther into the future, SpaceX’s flight-proven launch of PAZ and two of its own prototype communications satellites is just about two weeks away from its own static fire test, this time at the West Coast’s Vandenberg Air Force Base. Such an extended shutdown would be utterly unprecedented, but if 2017 and 2018 have done anything at all, they’ve tempered tendencies towards knee-jerk claims of “that’ll never happen!”

Here’s to hoping that Congress can get their act together and return to those they represent the bare minimum of federal stability, for both federal employees and those that depend upon them.
Update: After a solid two days of shutdown, the Senate has apparently reached an agreement to pass a continuing resolution that will maintain funding for another three weeks, after which a new FY2018 budget must be passed to avoid another shutdown. While this thankfully means that the impact to the Space Coast and the Air Force’s 45th Space Wing should be relatively small, I have left my above thoughts on the potential impacts of a longer shutdown untouched for posterity.
Senate has voted on an amended bill to fund U.S. government for 3 weeks. Bill now heads back to the House for debate & vote. If it passes the House without changes, the President then needs to sign it into law. Once all those things happen, the government reopens. Then… 1/2

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.
