Less than a year after tank farm assembly began in South Texas, SpaceX has begun the painstaking process of filling Starship’s first orbital launch site with thousands of tons of rocket propellant.

Comprised of seven giant custom-built tanks, the last of which SpaceX installed and ‘sleeved’ in mid-October, Starbase’s first orbital-class tank farm is a bit like the pad’s circulatory system and needs to store, chill, and distribute all the propellant needed for a rocket launch. To support Starship and Super Heavy, both the largest individual rocket stages and the largest integrated rocket ever built, its launch site and tank farm have to be equally immense. In classic SpaceX fashion, the company has strived to keep the costs of that tank farm low and its speed of construction high, resulting in a setup that’s fairly unique as far as launch pads go.

Perhaps nothing emphasizes the scale of Starship’s first orbital-class tank farm than the process of filling it with the supercool propellant and fluids its designed to hold.

In mid-September, SpaceX began delivering cryogenic fluids to Starbase’s orbital tank farm for the first time ever. Instead of propellant, dozens of tanker trucks delivered liquid nitrogen to one or two of the farm’s tanks between mid-September and mid-October. Altogether, around 40-60 truckloads was delivered – only enough to partially fill one tank. That liquid nitrogen also appeared to be piped into two of the farm’s three liquid oxygen tanks, meaning that it may have only been used to clean and proof test them.

Combined, the farm’s seven main tanks should be able to store roughly 2400 tons (5.3M lb) of liquid methane (LCH4), 5400 tons (12M lb) of liquid oxygen (LOx), and 2600 tons (5.7M lb) of liquid nitrogen (LN2). LCH4 and LOx are Starship’s propellant, while LN2 is needed to ‘subcool’ that propellant below its boiling point, significantly increasing its density and the mass of propellant Starships can store.

In recent weeks, LN2 deliveries have picked back up at the orbital tank farm, suggesting that more tanks are being cleaned and proofed. SpaceX may have also begun filling one or both of the farm’s dedicated LN2 tanks, though it’s hard to say for sure. More importantly, around October 17th, SpaceX began filling Starship’s orbital tank farm with liquid oxygen – real propellant – for the first time. Rather than a slow and cautious process, deliveries have streamed in almost daily ever since. As of November 4th, at least 74 tanker trucks have delivered LOx to the farm in 18 days.

Based on Department of Transportation (DOT) regulations that limit the gross weight of cryogenic tanker trucks to about 37 tons (~81,000 lb), each of those trucks has likely delivered around 20 tons (~45,000 lb) of LOx to Starbase. Altogether, that amounts to around 1500 tons (3.3M lb) delivered in less than three weeks – enough to fill about 80% of one of the farm’s three LOx tanks or a quarter of its total LOx storage capacity.

Based on data from AI-based tracker Starbase Deliveries, which can only count daytime deliveries, at least 134 tankers have delivered LCH4, LOx, or LN2 to Starbase’s orbital and suborbital launch sites between October 4th and November 4th – an average of 4.3 per day. At that rate, even if every delivery went to the orbital pad, it would take SpaceX nearly four months just to fill the orbital tank farm. Put simply, the facilities and logistics required to support even a single orbital Starship launch are gargantuan.

Tesla Semi is officially headed to Europe

Tesla has officially confirmed plans to bring its all-electric Semi truck to Europe, with full specifications and market-launch details set for unveiling at the IAA Transportation trade fair in Hannover, Germany.

The event runs September 15–20, with a possible press preview on September 14. The announcement, shared via Tesla’s Semi account, marks a significant expansion beyond North America nearly nine years after the truck’s original 2017 reveal.

In the United States, the Semi’s path has been gradual. Limited pilot production and customer deliveries began in late 2022, primarily to fleets such as PepsiCo. After years of refinement, high-volume manufacturing started on April 29, 2026, at a dedicated facility adjacent to Gigafactory Nevada.

The plant targets an annual capacity of 50,000 units, though the ramp is expected to be gradual, with “many thousands” of trucks projected by the end of 2026.

Demand is building, with recent orders including 500 units for Einride (deliveries starting September 2026, serving Amazon and others) and hundreds more from operators such as WattEV. Pricing stands at approximately $260,000 for the Standard Range and $290,000 for the Long Range before incentives.

Tesla Semi pricing revealed after company uncovers trim levels

Earlier in 2026, Tesla finalized production specifications that incorporated substantial updates. In February, the company detailed two variants designed for a full 82,000-pound gross combination weight.

The Standard Range offers about 325 miles of range with a 548 kWh battery and curb weight under 20,000 pounds. The Long Range delivers roughly 500 miles with an 822 kWh pack and a 23,000-pound curb weight. Both use three independent rear-axle motors producing up to 800 kW (about 1,073 horsepower), achieve energy consumption of around 1.7 kWh per mile, and support megawatt-class charging at up to 1.2 MW—recovering about 60 percent of range in 30 minutes through the MCS standard.

Additional refinements include a roughly 1,000-pound weight reduction versus earlier prototypes, improved aerodynamics, a 48-volt electrical architecture, electric power take-off up to 25 kW for refrigerated trailers, and fleet management software with over-the-air updates.

These advances position the Semi as a competitive option against diesel trucks on operating costs and performance. For Europe, adaptations such as lighting, cab configurations (including potential sleeper options), and regulatory compliance are anticipated.

With series production underway in Nevada and major fleet commitments secured, the upcoming IAA reveal will clarify timelines, European-specific specs, and pricing, potentially accelerating electrification of heavy-duty freight on both continents.

Tesla Robotaxi gets a massive upgrade in Nevada

Nevada regulators just approved a massive expansion of Tesla’s robotaxi fleet across the entire county.

Tesla’s robotaxi footprint in Nevada just grew by roughly 500 times in a single regulatory vote.

The Nevada Transportation Authority approved Tesla’s full Autonomous Vehicle Network Company permit on Thursday, clearing the way for the company to deploy up to 5,000 driverless vehicles across Clark County over the next 12 months. The decision came during a four hour general session meeting that Tesla investor Sawyer Merritt watched live and reported on X, noting the vote replaces the interim order that had limited Tesla to just 10 robotaxis on a narrow stretch of the Las Vegas Strip.

That earlier cap, covered here after it surfaced on August 13, came with restrictions that looked stricter than what Tesla runs in Austin: a 45 mph speed ceiling, no airport pickups, and a geofence confined to the Strip corridor. The new approval extends Tesla’s operating authority to all of Clark County, with room to request an even wider geofence across the state.

Tesla representatives at the meeting said they have no intention of putting 5,000 cars on the road right away. Commercial rides are expected to start within 30 days, pending vehicle inspections, insurance filings, and fare approval, the standard steps every robotaxi operator in Nevada has had to clear.

Tesla’s own Robotaxi account replied to the news with a short line, The golden future is upon us.

The timing lines up with Tesla’s broader robotaxi push this month. The company is preparing to open Cybercab rides to the public in Austin as soon as this month, and it opened a sweepstakes for riders to win a seat at the launch event. Tesla filed its original application for a 5,000 vehicle Nevada fleet back in June, a request regulators trimmed to 10 vehicles when they issued the interim order in July. Thursday’s vote effectively grants the number Tesla asked for from the start.

Zoox, the Amazon owned robotaxi operator, has run in Nevada since 2025 and was capped at 100 vehicles before Thursday’s decision. Tesla’s new ceiling puts it well ahead of that comparison on paper, though the company has said its actual fleet size will depend on how quickly FSD v15 rolls out, the software update executives have called the gateway to scaling unsupervised robotaxi operations nationwide.

Tesla admits to slow Model Y Robotaxi integration, but for a good reason

Tesla welcomed JPMorgan analysts to one of its factories earlier this month, with the Wall Street firm highlighting its findings in a new note to investors. One of the more pertinent pieces of information is that Tesla admitted to slowly integrating Model Y vehicles into its Robotaxi fleet, but it has a good reason.

JPMorgan analysts recently toured Tesla’s Fremont Factory and met with the company’s investor relations team, emerging with a clearer picture of the automaker’s Robotaxi strategy. According to the bank’s note, Tesla is intentionally limiting the addition of Model Y vehicles to its existing Robotaxi fleet.

The firm’s analysts said:

“Tesla indicated it is intentionally holding back on adding Model Y units to the robotaxi fleet, expressing confidence in its ability to scale Cybercab in the near-term. On FSD V15, Tesla views this release as a step-change in performance, comparable to the leap from V13 to V14. The V15 upgrade encompasses seven core technologies, with ~40% of those currently being tested in the robotaxi fleet, where initial feedback has been encouraging.”

Far from signaling delays or doubts about autonomy, the move reflects strong management confidence in the near-term scalability of the purpose-built Cybercab.

Tesla has operated its Robotaxi service primarily with modified Model Ys since launching in Austin and expanding to other markets. Yet the company is now deliberately holding back further Model Y conversions. The rationale is straightforward: leadership believes the Cybercab, a two-seat, steering-wheel- and pedal-free vehicle optimized for high utilization, can ramp production and deployment more efficiently in the coming months.

This dedicated form factor promises better unit economics for the majority of rides, which typically involve one or two passengers, while freeing consumer Model Y inventory for retail sales.

Supporting this pivot is Full Self-Driving (FSD) software version 15, which Tesla describes as a genuine step-change in performance, comparable to the leap from V13 to V14. The update incorporates seven core technologies; roughly 40 percent are already undergoing real-world testing in the current Robotaxi fleet, with early feedback described as encouraging.

Tesla is carefully managing software development to minimize regressions in core driving functions as new capabilities are added. Management positions V15 as the primary gateway to scaling unsupervised FSD. Importantly, the existing AI and Hardware 4 stack is already capable of running V15 and supporting unsupervised operation.

Cybercab itself is only the first vehicle on the platform. Tesla reiterated that additional form factors will follow, pointing to concepts such as the earlier “Robovan” demonstration as examples of how the architecture can evolve.

Parallel progress continues on the Optimus humanoid robot, which remains on track for start of production in the coming months, with commercial sales possible as early as the second half of 2027. Generation 3 details will be revealed closer to production to preserve competitive advantages, while Generation 4 scope will draw on real-world Gen 3 experience.

JPMorgan left the meeting with a deeper appreciation for Tesla’s manufacturing automation and maintained its $475 price target. The decision to slow Model Y Robotaxi integration is therefore not a setback but a calculated prioritization of a more efficient, purpose-built solution that management believes is ready to scale.
