ULA set to ship Vulcan rocket to Florida for Moon lander launch
After many years of delays, all the parts of the United Launch Alliance’s next-generation Vulcan Centaur rocket are about to converge on Florida for their first launch.
Unveiled in 2015, ULA has been working on Vulcan Centaur since at least 2014. Following Russia’s first illegal invasion of Ukraine, countries around the world attempted to punish the aggressor mainly through economic sanctions. In the US, those sanctions included bans on the import of most Russian aerospace technologies, including the RD-180 engines that still power ULA’s Atlas V workhorse rocket in 2023. In 2014, ULA announced that it would work with Blue Origin to integrate the startup’s BE-4 engine into a new rocket booster to end its reliance on Russian engines.
More than eight years later, that BE-4 engine is finally ready for flight, and the rest of the first two-stage Vulcan rocket appears to be right behind it.

Eastward-bound
In a burst of New Year activity, CEO Tory Bruno confirmed that Vulcan Flight 1’s core stage (booster) has been fully assembled, buttoned up, and loaded onto ULA’s transport ship. The aptly named RocketShip will ferry the booster from ULA’s Decatur, Alabama factory to Cape Canaveral, Florida, where it will enter the final stages of launch preparation at the company’s Cape Canaveral Space Force Station (CCSFS) LC-41 pad.
Simultaneously, ULA has finished proof testing Vulcan’s first Centaur V upper stage, a larger and more advanced version of the Centaur III stage ULA and its predecessors have been flying for decades. Centaur V is almost twice as wide as Centaur III and is designed to hold two and a half times more propellant, enabling significantly higher performance in some scenarios.
Additionally, while ULA has partially abandoned plans for a reusable upper stage called ACES (Advanced Cryogenic Evolved Stage), some of those improvements may still be added to Centaur V. Compared to Centaur III, Centaur V’s longevity in space will grow from 8 to 12 hours. ULA is also developing a “mission extension kit” that will allow it to operate for multiple months – unprecedented for a rocket stage powered by cryogenic propellant.
Photos taken by a local paper appear to indicate that ULA is shipping one or more payload fairing (nosecone) halves alongside Vulcan’s first flightworthy booster. While unconfirmed, it would make sense for ULA to ship Vulcan’s booster and fairing together. Another tweet from Tory Bruno indicates that ULA intends to ship Vulcan’s booster and upper stage together, increasing the odds that all components will be aboard RocketShip when it departs for Florida.
A New Workhorse
Vulcan Centaur is ultimately designed to fully replace ULA’s existing Delta IV and Atlas V rockets. Building and operating two very different rockets simultaneously is undoubtedly one of the reasons that ULA’s launch costs are so much higher than SpaceX’s, and simplifying to a single production line is one clear way to achieve major cost savings. ULA hopes that the simplest version of Vulcan will eventually cost about $100 million per launch – still far more than SpaceX’s base Falcon 9 price [PDF] but potentially more competitive than Atlas V. That’s unclear, though, as Bruno has previously stated that Atlas V’s launch costs have fallen to about $100 million apiece thanks to unrelated cost savings.
Regardless, Vulcan Centaur will be a capable rocket and its price is close enough to SpaceX’s extremely competitive Falcon 9 for it to be a mostly valid option for launch customers who want diversity or want to avoid SpaceX for less rational reasons. Vulcan has secured more than 70 launch contracts thanks to ULA’s intimate relationship with the US military and Amazon’s reluctance to launch its Project Kuiper internet satellites with the company behind Starlink, a direct competitor.
Fitted with two BE-4 engines, six solid rocket boosters (SRBs), and unknown upgrades, ULA says the most capable version of Vulcan Centaur will be able to launch up to 12.1 tons (26,700 lb) to the Moon, 15.3 tons (33,700 lb) to geostationary transfer orbit (GTO), and 27.2 tons (60,000 lb) to low Earth orbit (LEO). To high orbits, the most capable Vulcan variant will fairly competitive with SpaceX’s Falcon Heavy rocket. To low orbits, it will generally match or slightly exceed the performance of an expendable Falcon 9, but likely for a much higher price. By every measure, the simplest and cheapest Vulcan variant is significantly less capable than even a partially reusable Falcon 9 and will likely cost 50-100% more.
Moon or bust
Indicating ULA’s confidence in the unflown rocket, the main target of Vulcan’s first launch is the Moon. Vulcan Flight 1 will carry two main payloads: the first two Amazon Kuiper satellite prototypes and Pittsburgh startup Astrobotic’s first Peregrine Moon lander. After deploying both Kuiper satellites in low Earth orbit, Centaur V will fire up again and attempt to send the 1.3-ton (~2850 lb) Peregrine lander directly to the Moon – also known as a trans-lunar injection (TLI) burn. Developed as part of NASA’s Commercial Lunar Payload Services (CLPS) program, Peregrine will be tasked with entering orbit around the Moon and eventually landing up to 70-90 kilograms (150-200 lb) of payload on the lunar surface.
The first Peregrine Moon lander is fully assembled and currently in the middle of extensive integrated testing. If successful, ULA CEO Tory Bruno says that Vulcan will likely be ready to launch sometime in Q1 2023, though Q2 2023 is more likely.

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.

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.
