Update: SpaceX Falcon 9 booster B1051 aced its Starlink-27 launch without issue, becoming the first Falcon booster ever to complete ten consecutive launches and landings.

The mission’s success also means that SpaceX’s internet constellation has more than 1500 functional satellites in orbit, leaving Starlink just two more 60-satellite batches and a few months of orbit-raising away from the ability to deliver internet virtually anywhere on Earth.

Next Spaceflight reports that SpaceX’s next Starlink launch – scheduled as few as five days after the last mission – will see Falcon 9 mark a hugely significant milestone for truly reusable rocketry.

According to Next Spaceflight’s sources, SpaceX has chosen Falcon 9 booster B1051 to launch Starlink-27 – the constellation’s 26th operational mission – as early as 2:42 am EDT (06:42 UTC) on Sunday, May 9th. Scheduled eight weeks (56 days) after the same booster’s last orbital-class launch and landing and just five days after SpaceX’s 25th operational Starlink launch, Starlink-27 will be Falcon 9 B1051’s 10th launch.

While seemingly minor in the scope of SpaceX’s unending roster of spaceflight ‘firsts,’ B1051’s Sunday flight will make Falcon 9 the first reusable liquid rocket booster of any kind to complete ten orbital launches. With that tenth launch and (hopeful) landing, SpaceX will cross a largely symbolic – but still significant – milestone that many traditional aerospace companies and direct competitors have used for at least a decade to rationalize resting on their laurels and continuing to design and build expensive, expendable rockets with no serious path to reusability.

For the entirety of SpaceX’s operational life, its only two real competitors have – and continue to be – US conglomerate United Launch Alliance (ULA) and European conglomerate Arianespace. Almost like clockwork, both extremely conservative groups – comprised of numerous traditional, entrenched aerospace and military contractors – have gone through a similar cycle of belittlement and dismissal, denial, goalpost-moving, disbelief, and resignation as SpaceX announced plans for reusability, began real-world attempts, and gradually worked out the kinks.

As it became clear that SpaceX would succeed in its efforts to vertically launch and land Falcon 9 boosters and ULA and Arianespace had to move their goalposts from “it’ll never work,” both generally settled on largely arbitrary claims that even if SpaceX could land rockets, reuse would never be economical. ULA went even further than Arianespace with an explicit claim – derived from armchair analysis built on opaque, unspecified assumptions – that SpaceX’s approach to Falcon reuse would “require ten [booster] uses to be profitable.” [PDF]

Instead, ULA – proudly standing on its high horse – proffered an alternative called “SMART (Sensible Modular. Autonomous Return Technology) Reuse” for its next-generation Vulcan rocket. Instead of landing and reusing entire boosters like SpaceX, ULA would develop an extremely complex engine section that would detach from Vulcan in mid-air, deploy an experimental inflatable heat shield, and be grabbed out of the sky with a helicopter. Even back when the concept was first announced in 2015, ULA’s schedule for SMART reuse would have seen the technology debut no sooner than the mid 2020s.

More than half a decade later, ULA no longer talks about “SMART Reuse” and it certainly doesn’t talk about the program’s schedule. As late as mid-2020, though, CEO Tory Bruno still parrots ULA’s arbitrary estimate that reusability only makes sense after ten flights per booster – and with the added bonus of new goalposts that demand that that “breakeven flight rate…be achieved as a fleet average.”

Arianespace executives have echoed similar sentiments over the years and more recently implied that it would only ever make sense to invest in SpaceX-style reusability if the conglomerate could guarantee at least 30 launch contracts annually.

In the meantime, Arianespace and ULA all but handed the vast majority of their commercial market share to SpaceX’s far more affordable Falcon 9 and Falcon Heavy. As a result, the company has effectively taken over the commercial spaceflight industry while its relentless, iterative development approach have produced refined Falcon 9 and Heavy rockets with an unprecedented degree of reusability. Looking at all Falcon 9 Block 5 boosters that have flown more than once, the fleet average is already more than five launches less than three years after the Block 5 upgrade debuted.

SpaceX has also demonstrated – multiple times – that it can launch the same Falcon 9 booster twice in less than a month, quite literally halving the Space Shuttle’s 54-day record while likely requiring somewhere between 10 and 100 times less hands-on work. Just last month, NASA gave SpaceX’s reusability work the ultimate blessing when a Falcon 9 booster launched astronauts for the second time. Of the more than 1500 Starlink satellites SpaceX has launched over the last two years, not a single one of those internet satellites flew on a new Falcon 9 booster.

Finally, Falcon 9 booster B1051 is now on track to become the first liquid rocket booster in history to cross the ten-flight mark set by ULA and targeted by SpaceX CEO Elon Musk. For Musk, “ten flights” has long been a line drawn in the sand – explicitly meant to be an arbitrary target. In reality, after flying multiple Falcon 9 boosters six, seven, eight, and even nine times apiece, SpaceX already believes that the rocket’s existing design is capable of significantly surpassing that target.

Perhaps most importantly, despite the fact that Arianespace and ULA have scarcely begun to even attempt to counter Falcon 9 and Falcon Heavy, SpaceX is already working on Starship – a far more capable, fully-reusable rocket designed from the ground up with lessons learned from Falcon.

The Tesla Semi recently received a strange-but-understandable comparison from automotive enthusiast and former long-time late-night television show host Jay Leno.

In a recent interview with MotorTrend, legendary comedian and automotive enthusiast Jay Leno shared his impressions after driving Tesla’s long-range Semi truck, offering one of the most vivid descriptions to date:

“It’s like driving an office building.”

The comparison may seem quirky—office buildings evoke images of immobility rather than motion—but it aptly conveys the experience of commanding a massive 23,000-pound Class 8 electric truck that delivers sports-car acceleration.

Lenotested the production-spec Long Range model, which is rated for up to 500 miles of range. He was visibly impressed by its performance, noting how the enormous vehicle moves with surprising urgency.

“It’s as fast as a Tesla, but it’s like driving an office building,” he remarked. “It’s this huge thing that moves like right now. You go 500 miles. You get 60% charge in 30 minutes. You’re saving on fuel costs. It seems quite good.”

The reaction highlights the cognitive dissonance at the core of the Tesla Semi. Traditional diesel semi-trucks are slow, noisy, and expensive to run. The Semi rewrites the rules with instant torque from its tri-motor electric powertrain, producing up to 800 kW.

Despite its size, the truck feels agile thanks to full electric steering assist, upgraded actuators borrowed from the Cybertruck, and a 48-volt electrical architecture that improves responsiveness and efficiency.

Tesla reports real-world energy consumption below 1.7 kWh per mile for the Long Range version. Megacharger stations can deliver a 60% charge in roughly 30 minutes, making the truck suitable for long-haul operations.

Additional features include an electric Power Take-Off (ePTO) capable of 25 kW for trailer refrigeration or other equipment, and a driver-focused cab with a central seating position for optimal visibility and a quiet, high-tech interior.

Fleet operators stand to benefit significantly from the economics. Diesel trucks often cost nearly one dollar per mile when including fuel, maintenance, and downtime.

Tesla projects the Semi can reduce operating costs to as low as 15 cents per mile through cheaper electricity, regenerative braking that minimizes brake wear, and reduced service requirements. While early deployments, like Pepsi’s, focused on shorter routes, the 500-mile variant targets cross-country applications.

Obstacles remain. A fully loaded tractor-trailer can reach 80,000 pounds, which reduces real-world range compared to the unloaded test conditions. Building out a nationwide Megacharger network will be essential for broader adoption. The Semi also carries a higher upfront price than conventional diesels, though total cost of ownership and available incentives frequently tip the scales in its favor over time.

Tesla Semi hauls fresh Cybercab batch as Robotaxi era takes hold

Leno’s “office building” description resonates because it captures the unexpected thrill of piloting something so large yet so capable. As the trucking industry faces pressure to cut emissions and control rising fuel expenses, the Semi offers a compelling alternative that excels in performance, comfort, and efficiency.

Coming from a man who has driven everything from vintage classics to modern hypercars, Leno’s genuine enthusiasm adds weight to the verdict.

The Tesla Semi is emerging as more than an experimental EV—it represents a practical vision for the future of heavy-duty transport where massive rigs accelerate instantly, and the numbers finally make sense. If fleet results continue to validate the claims, the era of diesel dominance could be drawing to a close.

Tesla has expanded the color palette it offers on its mass market vehicles in the United States, giving buyers of the Model 3 and Model Y a few additional options than before.

Delivering a fresh splash of color to its lineup, Tesla is giving U.S. buyers two stunning new blue options that are already turning heads. Starting on May 8, the automaker updated its North American configurator to introduce Marine Blue on Model Y Premium trims and Frost Blue exclusively on the Model 3 Performance.

The move replaces the long-running Deep Blue Metallic, a staple for over eight years, and brings previously exclusive shades stateside.

Marine Blue, a deep, rich oceanic hue formerly limited to Europe and Asia-Pacific markets, is now available on Model 3 and Model Y RWD and Long Range AWD Premium variants. Priced at a $1,000 upgrade—standard for Tesla’s premium paints—it delivers a sophisticated, metallic finish that shifts beautifully under light.

Tesla North America highlighted the change directly in an official post, confirming Marine Blue as the new flagship blue for non-Performance models.

Frost Blue, on the other hand, is the real crowd-pleaser for enthusiasts. Previously reserved for the flagship Model S and Model X, this lighter, icy metallic shade is now offered at no extra cost on Model 3 Performance and Model Y Performance trims.

Performance buyers effectively get a premium color included in the base price, a smart perk that Tesla has extended to higher-end variants across the board. Early in-person sightings and configurator renders show Frost Blue’s cool, modern vibe popping against the cars’ sleek lines, especially with black wheels and red brake calipers.

The timing couldn’t be better. With Tesla pushing refreshed Model 3 and Model Y refreshes amid growing competition, these updates add visual excitement without major redesigns.

Deep Blue Metallic orders are being transitioned to the new shades, according to customer reports and Tesla communications. In the U.S., Puerto Rico, and Mexico, the options are live now; Canada sees limited Frost Blue availability on the Model 3 Performance.

Tesla’s color strategy continues to evolve, borrowing from higher-end models to refresh mass-market EVs. Now that we bid farewell to the Model S and Model X, some of their colors might be available on the more widely available Model 3 and Model Y.

Tesla Semi’s official battery capacity leaked by California regulators

A California regulatory filing just confirmed the exact battery size inside each Tesla Semi variant.

Published

By

A regulatory filing published by the California Air Resources Board in April 2026 has put official numbers on what Tesla Semi owners and fleet buyers have long wanted confirmed: the exact battery capacities of both the Long Range and Standard Range Semi truck variants. CARB is California’s independent air quality regulator, and it certifies zero-emission powertrains before they can be sold or operated in the state. When a manufacturer submits a vehicle for certification, the resulting executive order becomes a public document, making it one of the most reliable sources for confirmed production specs on any EV.

The document lists two certified powertrain configurations. The Long Range Semi carries a usable battery capacity of 822 kWh, while the Standard Range version comes in at 548 kWh. Both use lithium-ion NCMA chemistry and share the same peak and steady-state motor output ratings of 800 kW and 525 kW respectively. Cross-referencing Tesla’s published efficiency figure of approximately 1.7 kWh per mile under full load, the 822 kWh pack supports roughly 480 miles of real-world range, which aligns closely with Tesla’s advertised 500-mile figure for the Long Range trim. The 548 kWh Standard Range pack works out to approximately 320 miles, again consistent with Tesla’s stated 325-mile target.

Here is a direct comparison of the two versions based on the CARB filing and published specs:

Tesla Semi Spec Long Range Standard Range
Battery Capacity 822 kWh 548 kWh
Battery Chemistry NCMA Li-Ion NCMA Li-Ion
Peak Motor Power 800 kW 525 kW
Estimated Range ~500 miles ~325 miles
Efficiency ~1.7 kWh/mile ~1.7 kWh/mile
Est. Price ~$290,000 ~$260,000
GVW Rating 82,000 lbs 82,000 lbs

The timing of this certification is not incidental. On April 29, 2026, Semi Programme Director Dan Priestley confirmed on X that high-volume production is now ramping at Tesla’s dedicated 1.7-million-square-foot facility in Sparks, Nevada. A key advantage of the Nevada location is vertical integration: the 4680 battery cells powering the Semi are manufactured in the same complex, eliminating the supply chain bottleneck that had delayed the program for years.

Tesla’s long-term goal is to reach a production capacity of 50,000 trucks annually at the Nevada factory, which would represent roughly 20 percent of the entire North American Class 8 market. With CARB certification now in hand and the production line running, the regulatory and manufacturing groundwork for that target is in place.
