SpaceX delivers largest commercial satellite in kick off of Falcon 9 marathon
SpaceX has successfully completed its 13th launch of 2018, kicking off a marathon of three new Falcon 9 Block 5 booster debuts with the launch of the Telstar 19V communications satellite, potentially breaking the record for the largest commercial satellite ever launched at 7000 kg (15,500 lb).
Despite the heft of its payload and partially thanks to a slightly lower parking orbit for the satellite, Falcon 9 booster B1047 – the second Block 5 booster to roll off the assembly line – managed to successfully land aboard the autonomous spaceport drone ship (ASDS) Of Course I Still Love You (OCISLY), stationed approximately 650 km (400 mi) off the Florida coast at launch time.
While the booster was unable to maintain a live video feed through its high-speed reentry and Atlantic landing, SpaceX’s cameras on OCISLY managed to reconnect a few seconds after touchdown to show the 50-meter (160-foot) tall rocket safely resting on the drone ship. As the webcast host noted, Falcon 9 Block 5 features a number of prominent upgrades designed to enable levels of reusability and reliability essentially unprecedented in the world of orbital rocketry.

Rocket trials
Now more than two months after the first Block 5 booster’s – B1046 – debut in May 2018, the software engineer hosting SpaceX’s Telstar 19V webcast was likely speaking more from a place of experience than of hope. Per CEO Elon Musk’s press call just prior to Block 5’s debut, he noted that SpaceX intended to conduct an extensive analysis of that pathfinder booster, including significant disassembly and perhaps some limited destructive testing of certain critical or high-risk components. Musk didn’t expect B1046 to fly for at least another “couple of months”.
This is critical because SpaceX’s manifest over the next several weeks is fairly aggressive – Iridium-7 is scheduled to lift off from Vandenberg, CA three days from today (July 25th), the next Florida launch is aiming for a static fire next weekend and a launch NET 1:19 am EDT August 2, and the second imminent Florida mission is penciled in for launch NET 11:35 pm EDT August 17. Those rapid-fire Florida launches will push both SpaceX’s pad and drone ship turnaround capabilities to their limits, requiring almost non-stop work to ensure both are available for the next mission in two weeks or less.

Not to be (at least relatively) one-upped, SpaceX’s Vandenberg launch pad – known as SLC-4E – is scheduled to push its own turnaround limits by flying two missions in roughly 40 days, just shy of the current SpaceX record of 36 days between launches. Perhaps more excitingly, that September 4 SAOCOM 1A mission looks like a prime candidate for the debut of SpaceX’s yet-unused Californian landing zone, barely spitting distance from the SLC-4E launch pad.
Still, the question remains: what boosters are going to launch these four missions?
- B1051 is not believed to have left the Hawthorne, CA factory yet, and has been stated by NASA to be reserved for the first uncrewed Crew Dragon mission (DM-1), unlikely to occur before Q4 2018.
- B1050 is currently on-stand in McGregor, TX and is likely to be shipped to a launch pad within a week or two.
- B1049 was almost certainly shipped to Florida to support either of the two upcoming August launches.
- B1048 will launch Iridium-7 on July 25, land on Just Read The Instructions, and likely remain in California for future VAFB missions.
- B1047 just successfully launched Telstar 19V (July 22) and will be brought back to Port Canaveral over the next several days before heading to one of SpaceX’s Florida refurbishment facilities, presumably to prepare for an imminent future launch.
- B1046 is likely disassembled in Hawthorne, CA, unable to support a launch for another few weeks – perhaps it’s nearly ready, however

Put simply, it seems almost impossible for SpaceX to accomplish its ambitious manifest over the next 4-6 weeks without reusing a freshly-recovered Falcon 9 Block 5 booster. B1046 is a possibility, as is B1047 or B1048, although the latter two options would smash SpaceX’s previous record for Falcon booster turnaround (~70 days) by more than half, requiring in a return to shore, refurbishment or nondestructive analysis, and preparation for a static fire in as few as ~14-21 days.
Regardless, B1047’s successful Telstar 19V launch and landing have kicked off what is bound to be an extremely exciting period for SpaceX and its aspirations of highly-reusable rocketry.

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.
