SpaceX aborts Starship launch after Raptors produce too much thrust
Update #3: SpaceX CEO Elon Musk says that Starship prototype SN10 automatically aborted a 2:15 pm CST (UTC-6) launch attempt after the rocket determined that its three Raptor engines were producing too much thrust.
Instead of scrubbing for the day, Musk says that SpaceX will instead increase the flight computer’s thrust limits and try again as early as 4:30 pm CST – still well before today’s window closes at 6:30 pm. SpaceX ended its webcast but will start a second webcast a few minutes prior to the next launch attempt.
Update #2: As of Wednesday morning, SpaceX has officially confirmed that Starship is on track for a third high-altitude launch and ‘bellyflop‘-style landing attempt sometime later today.
As of 11am CST (UTC-6), FAA approval is in hand, weather is encouraging, Starship prototype serial number 10’s (SN10) flaps have been unchained, and SpaceX has cleared the launch site – all signs that the rocket’s launch attempt is imminent. Much like SN8 and SN9 coverage, SpaceX says it will make a public livestream of SN10’s launch available to the public “a few minutes” before liftoff. Stay tuned and follow along with NASASpaceflight’s live coverage in the meantime.
Update: SpaceX has asked Boca Chica Village residents to prepare to evacuate the area as early as Wednesday morning for Starship’s third high-altitude launch and landing attempt.
The odds of things going so wrong that a Starship launch could actually end with a prototype impacting at or near the Village and the handful of non-employee holdouts still residing there are minuscule. However, FAA safety regulations and SpaceX’s contingent launch license mean that evacuations are now a routine part of Starship’s high-altitude flight tests since Starship SN8 took the first step beyond short hops. While undeniably inconvenient for the few remaining residents, today’s evacuation notice – short of an official SpaceX.com confirmation – does serve as the ultimate sign that Starship SN10’s first launch attempt is firmly scheduled on Wednesday, March 3rd.
With FAA approval in hand, weather rapidly improving, and the latest rocket prototype seemingly raring to go, the stars are aligning for SpaceX’s third high-altitude Starship launch and first triple-engine landing attempt.
As of March 1st, publicly-available FAA “temporary flight restrictions” (TFRs) and weather forecasts both agree that SpaceX is currently preparing to launch Starship serial number 10 (SN10) as early as Wednesday afternoon CST (UTC-6), March 3rd. Barring surprises, that gives SpaceX a healthy three-day period to account for any potential technical or weather-related delays.
Originally scheduled as early as the last week of February, unspecified delays pushed Starship SN10’s launch debut schedule into March. In general, the vehicle’s path to flight has been much smoother than Starship SN8 and SN9, both of which ran into hardware bugs and opaque FAA licensing issues. With Starship SN10, the FAA approved SpaceX’s “modified” launch license well before the company was ready for flight – and even before the rocket had attempted its first static fire.
Unlike Starships SN8 and SN9, both of which took anywhere from 6-10 weeks to go from rolling off the factory floor to preparing for their first launch attempts, SN10’s first launch attempt appears likely to occur less than five weeks after the rocket arrived at the launch site. The sequential improvements in efficiency and reliability between those three prototypes is a fundamental part (or goal, at least) of SpaceX’s iterative development process.
Still, Starship SN10’s preflight flow wasn’t completely free of drama and SpaceX ultimately put the rocket through a second triple-Raptor static fire after the first test revealed an issue with one of those engines. SpaceX swapped that faulty engine out in record time and fired up SN10 again less than 48 hours after test #1, seemingly producing more satisfactory results the second time around.
Unlike its predecessors, SN10 will also debut a new triple-engine approach to landing, aiming to increase redundancy and boost the odds of a successful touchdown even if one of the Starship’s three Raptors fail during a last-second flip maneuver. Building on the failures of SN8 and SN9, it’s safe to say that SN10 has the best shot yet at sticking the landing.
TFRs show that two earlier launch windows on Monday and Tuesday (March 1st and 2nd) were canceled, leaving only the Wednesday, March 3rd airspace closure request still open. Wednesday was then backed up with two alternate windows on Thursday and Friday not long after.
Hardware-wise, Starship SN10’s cherry-on-top (an explosives-based flight termination system or FTS) was installed on February 28th. In the event that Starship loses control and strays past a certain point outside of its approved trajectory, that FTS would explode, breaching the rocket’s propellant tank, triggering vehicle breakup, and thus preventing it from harming the local populace. All told, SpaceX confirmation of a Wednesday launch attempt – and another official webcast – should be imminent. Stay tuned!

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 expands its mass-market color palette in the U.S.
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.
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.
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.
