SpaceX teases extreme Falcon 9 launch cadence goals in Starship planning doc

Published as part of an August 2019 environmental assessment (EA) draft for Starship’s prospective Pad 39A launch facilities, SpaceX revealed plans for a truly mindboggling number of annual Falcon 9 and Falcon Heavy launches by 2024.

As environmental planning documents, the figures should be taken with a large grain of salt and be treated as near-absolute ceilings rather than practical goals. Nevertheless, SpaceX revealed plans for its two Florida launch sites (LC-40 and LC-39A) to ultimately support as many as 70 annual launches of Falcon 9 and Heavy by 2024, less than five years from now.

Simply put, even the most dogmatic fan would have to balk at least a little bit at the numbers SpaceX suggested in its Starship EA draft. More specifically, SpaceX apparently has plans to support as many as 20 annual Falcon 9/Heavy launches from Pad 39A and an incredible 50 annual Falcon 9 launches from LC-40 as early as 2024.

“SpaceX plans to increase the Falcon launch frequency to 20 launches per year from LC-39A and up to 50 launches per year from LC-40 by the year 2024. However, as Starship/Super Heavy launches gradually increase to 24 launches per year, the number of launches of the Falcon would decrease.“

Two obvious options

Given just how significant of an increase a 70-launch annual cadence would be for SpaceX relative to their current record of 21 launches, it’s entirely possible that these numbers are really just a pipe dream included in a pending environmental assessment to hedge bets just in case a similar launch frequency is achieved over the next five years.

On the other hand, it’s possible that SpaceX – just now coming into the ability to reliably achieve a much higher cadence – has coincidentally become payload-constrained at almost the same time, meaning that the company’s customers’ payloads just aren’t ready for launch. This would explain, for example, why SpaceX has only launched 10 times this year when the company had already completed 15 launches by August 2018.

Additionally, it can be almost unequivocally assumed that all but 15-20 of those supposed 70 annual launches would come from SpaceX’s own internal demand for Starlink launch capacity. Assuming no improvements between now and 2024, 50 Falcon 9 launches could place as many as 3000 Starlink satellites in orbit in a single year, equivalent to more than 25% of the entire proposed ~11,800-satellite constellation.

Barring regulatory changes to US Federal Communications Commission (FCC) and International Telecommunication Union (ITU) requirements, SpaceX must launch at least half of all Starlink satellites (~5900) by November 2024 and finish launching the remaining ~5900 by November 2027. If SpaceX fails to reach those deployment milestones, the company runs the risk of losing Starlink’s domestic and international licenses to operate.

This would help to explain why SpaceX says that it’s planning to reach a maximum cadence of 70 annual launches “by 2024”, given that 2024 will be a pivotal year in the eyes of regulations currently in effect for Starlink.

Starship confusion

As noted in the quote above, SpaceX plans to eventually phase out Falcon 9 and Heavy launches as the company’s next-generation Starship and Super Heavy launch vehicle gradually comes online, proves itself reliable, and begins operational launch activities. According to SpaceX, given just how much mass Starship can nominally launch relative to both Falcon 9 and Heavy, far fewer launches will be needed to accomplish the tasks that would otherwise require several times more launches of SpaceX’s smaller vehicles.

SpaceX’s initial Environmental Assessment for Starship launches from Pad 39A caps the rocket’s maximum cadence at 24 annual launches. Oddly, this directly contradicts the goals set for Starship (formerly BFR) by CEO Elon Musk and SpaceX more generally. By building a launch vehicle that is fully and rapidly reusable, the goal has long been to deliver cheap, aircraft-like access to orbit at a completely unprecedented scale.

Starship was never meant to lower SpaceX’s annual launch cadence. (SpaceX)

This would technically mean that SpaceX could actually dramatically increase its launch cadence without increasing costs, allowing the company to perform currently nonsensical missions where Starship might launch payloads weighing just 5-10% of its total payload capacity. Airline operations routinely do things of a similar nature, sometimes flying just a fraction of their maximum passenger load to destinations for a variety of reasons.

Additionally, SpaceX has consistently indicated that Starship will rely heavily on orbital refueling to accomplish its ultimate deep space ambitions. Previous presentations from Elon Musk have shown that launches to the Mars or Moon with significant payload would require no fewer than five separate tanker launches and orbital refuelings, all of which would classify as one of the 24 annual launches SpaceX has described in its August 2019 EA draft. On their own, launching two Starships to Mars with 100 tons of payload each would require no fewer than 10-12 launches.

Ultimately, it’s unwise to draw any substantial conclusions from an Environmental Assessment like the one the above information has been taken from. This 39A-specific EA also ignores the possibility of a similar launch facility being developed in Boca Chica, Texas, which SpaceX explicitly acknowledges.

This particular draft is also the first Starship-related EA ever filed by SpaceX, and the company may thus be treating it more as a bare minimum with the intention of eventually pursuing far more ambitious launch rates once Starship has been established.

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.
