SpaceX’s next Falcon Heavy rocket on track for early 2023 launch

Published

on

Two weeks after SpaceX’s first Falcon Heavy launch in three and a half years, the US Space Force says that the rocket is on track to launch again “early next year.”

Immediately before and after Falcon Heavy’s first operational launch for the US Space Force, the Space Systems Command confirmed that the massive SpaceX rocket’s next military launch – USSF-67 – was scheduled no earlier than January 2023. The military also confirmed that USSF-67 would reuse two of the three Falcon Heavy boosters that helped launch USSF-44 on November 1st.

Two weeks later, the US Space Force’s tone hasn’t changed, and the Space Systems Command remains confident that Falcon Heavy is on track to launch USSF-67 less than three months after USSF-44.

Assuming the lack of a schedule change is intentional rather than a matter of not checking with SpaceX or other US stakeholders, no change is a good sign. Since the last time the SSC reported that USSF-67 was on track to launch in January 2023, SpaceX successfully launched its fourth Falcon Heavy rocket. USSF-44 was the company’s first launch directly into a geosynchronous orbit ~36,000 kilometers (~22,300 mi) above Earth’s surface.

SpaceX successfully recovered both of Falcon Heavy’s ‘side cores’ and has likely had enough time to thoroughly inspect each booster and begin the refurbishment process. If data gathered from the launch, landing, or recovered boosters uncovered issues with Falcon Heavy’s performance during USSF-44, USSF-67 would almost certainly be delayed. The chances of a delay are magnified by the fact that USSF-67 can’t launch until two of USSF-44’s Falcon Heavy boosters are refurbished and declared ready for a second flight.

But it appears that even a gap of 40 months between Falcon Heavy launches wasn’t enough to make SpaceX falter – at least after working out some prelaunch kinks. SpaceX accomplished a similar feat – launching two Falcon Heavy rockets in less than three months with one pair of side boosters – on the rocket’s second and third launches in April and June 2019. The mission that reused Flight 2’s side boosters was for the US Air Force, so SpaceX and the military already have direct experience tackling those challenges.

In the three and a half years since, SpaceX has gained a huge amount of experience recovering and refurbishing Falcon 9 Block 5 boosters and slashed its record turnaround (the time between two launches of the same booster) from 74 days to 21 days. SpaceX should thus have no issue turning Falcon Heavy side boosters B1064 and B1065 around for a second launch in January 2023, around 60 to 91 after their debut.

While preparing one Falcon Heavy rocket to launch USSF-67 in January, SpaceX – at least according to customer ViaSat – may also be preparing another Falcon Heavy rocket to launch the first ViaSat-3 satellite the same month. Unlike the US Space Force, which recently shipped [PDF] one of USSF-67’s payloads to Florida, ViaSat has yet to ship its first next-generation satellite to the launch site and says that milestone is scheduled for December 2022. That makes a February or March launch much more likely, but ViaSat recently told shareholders that ViaSat-3 remains on track to launch “in the earliest part of” Q1 2023.

Combined, USSF-67 and ViaSat-3 are scheduled to reuse Falcon Heavy side boosters B1064, B1065, B1052, and B1053. Each will use a brand new center core: B1068 for ViaSat-3 and B1079 for USSF-67, according to Next Spaceflight. Like USSF-44, which was the first time SpaceX intentionally expended a Falcon Heavy booster, both new center cores are expected to be expended.

For several reasons, assembling and preparing Falcon Heavy for launch is significantly more time-consuming than Falcon 9, so there will likely be at least a two, three, or even four-week gap between Falcon Heavy’s next two launches. But as long as USSF-67 and ViaSat-3 are ready to fly during narrow windows in early and late January, it appears that SpaceX could launch two Falcon Heavy rockets in one calendar month.

SpaceX has as many as five Falcon Heavy launches scheduled in 2023 – a stark change after more than three years without a single flight.

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

Published

on

Credit: SpaceX

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:

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 Assisted Driving expands to tenth EU country

Published

on

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’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.

Tesla starts showing how FSD will change lives in Europe

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 expands Robotaxi geofence in Houston with an ode to SpaceX merger

Published

on

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.

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.
