SpaceX Falcon 9 Block 5 booster ends launch #2 with spectacular dawn return
SpaceX Falcon 9 booster B1049 has completed its second successful launch and landing with a spectacular dawn return to Port of Los Angeles, where engineers and technicians will work to remove the rocket’s grid fins and landing legs and prepare the vehicle for transport to the company’s Hawthorne, CA factory and refurbishment facilities.
Once post-recovery processing is complete and B1049 is safe and snug inside one of SpaceX’s refurbishment facilities, the booster can be expected to be ready to perform its next (third) orbital-class mission perhaps just 2-3 months from now, whether or not there is a mission that needs its support.

Just ~48 hours after the Block 5 booster’s second successful launch and landing, this time aboard drone ship Just Read The Instructions (JRTI) after supporting the historic Iridium-8 mission, JRTI pulled into Port of Los Angeles with Falcon 9 in tow, backlit by a picturesque California sunrise. In September 2018, the same booster (B1049) successfully completed its launch debut from SpaceX’s LC-40 launch pad in Cape Canaveral, Florida before landing safely aboard drone ship Of Course I Still Love You (OCISLY).
This marks the second time ever that a Falcon 9 booster has launched from both coasts (Cape Canaveral, FL and Vandenberg, CA) and landed on both SpaceX drone ships (JRTI and OCISLY), an event that will likely become increasingly common as the company’s growing fleet of Falcon 9 Block 5 boosters become increasingly flexible and interchangeable. It’s also equally possible that – over time – a sort of regional fleet of Falcon 9s will ultimately accumulate at each of SpaceX’s three launch pads, ensuring that there is always a rocket ready and waiting to launch a customer payload with short notice and minimal production or refurbishment-related delays.

Among many of Falcon 9’s almost sculpture-like qualities, Teslarati photographer Pauline Acalin’s photos of the booster’s return exemplify just how reliably unperturbed Block 5 appears after performing multiple orbital-class launches, far from a rocket that traveled to ~90 km (~56 mi) while reaching speeds of 1.9 kilometers per second (6830 km/h, 4300 mph). SpaceX now reliably reuses Falcon 9’s titanium grid fins and landing legs with little to no refurbishment or touching up between launches and should eventually be able to retract the rocket’s legs after recovery, further cutting down on processing and refurbishment times.
Greater reusability, greater reliability?
As of today, it’s unclear how big of a role Falcon 9 Block 5 booster refurbishment has played into several hardware-readiness-related delays to several recent flight-proven Falcon 9 launches (SSO-A, SAOCOM 1A, and Iridium-8), but it is ultimately a fundamental reality of all manufacturing that rushing or ‘expediting’ work will typically hurt product quality and reliability and generally widen the cracks that mistakes can slip through. Interestingly, having a truly large fleet of flight-proven Falcon 9 Block 5 rockets on hand could dramatically improve the overall launch-readiness of Falcon 9 and Falcon Heavy and minimize chances of processing delays across the board.
SpaceX employees may already be to a point where they can plausible take stock of the company’s already-significant fleet of flight-proven Falcon 9s (B1046-B1049) to decide which booster is closest to launch-readiness before assigning it to a given mission. With four proven boosters on hand as of January 2019, options are fairly limited and regionality is likely to factor heavily into which booster launches which mission – there is no real cushion if problems arise with a given rocket or its preceding launch suffers its own delays. However, once that Falcon fleet grows to something like 10 or 15 booster, SpaceX could conceivably be able to guarantee booster availability regardless of prior launch delays or a given rocket’s condition after landing.

This may well be far less sexy than SpaceX’s ultimate goal of drop-of-the-pin, 24-hour reusability for Falcon and BFR boosters, but the fundamental fact of the matter is that the company may well be able to derive a vast majority of that practice’s value by simply having a large, well-kept fleet of Falcon 9 boosters that are at least moderately reusable. For a hefty chunk of the probable near-term future, a large fleet of rockets each capable of launching every 30-60 days would likely be able to support launch cadences that are currently unprecedented for a single company or rocket (i.e. dozens of launches per year).
Time is money, of course, so minimizing the turnaround time of Falcon boosters will ultimately remain a major priority, especially as the prospect of Starlink launches loom.

Tesla Semi gets strange-but-understandable comparison from Jay Leno

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.
