Boeing Starliner spacecraft successfully returns to flight 29 months after ill-fated debut
More than three years after SpaceX’s Crew Dragon spacecraft first safely reached orbit and almost three and a half years after Boeing’s Starliner crew capsule’s ill-fated launch debut, Boeing has finally returned to flight and made it farther than ever before towards a successful test flight.
Almost ten months after Boeing’s first attempt at Starliner’s second uncrewed Orbital Flight Test (OFT-2 #1), the stars aligned. As expected, the United Launch Alliance’s Atlas V rocket lifted off on time at 6:54 pm EDT (22:54 UTC) on Thursday, May 19th, ascending from Cape Canaveral Space Force Station (CCSFS) Launch Complex 41 (LC-41) without issue. After a four and a half minute burn, the Atlas V booster – powered by a Russian-built RD-180 engine – separated and the Centaur upper stage – powered by two Aerojet Rocketdyne RL-10 engines – took over.
Another six minutes later, Centaur shut down and Starliner ultimately separated from the rocket a bit less than 12 minutes after liftoff. Unlike SpaceX’s Crew Dragon, though, Starliner separated from its launch vehicle before reaching orbit – a task Boeing engineers chose to reserve for the spacecraft itself to limit stress on the spacecraft and crew in the event of a high-altitude abort. However, that design decision also adds significant risk in other ways and – after the spacecraft’s extremely poor performance during its first launch attempt – turns a Starliner launch into a sort of 30-minute cliffhanger.
While just a hair shy of true orbit, Starliner’s suborbital launch trajectory means that whether or not it wants to, the spacecraft will reenter Earth’s atmosphere about an hour after liftoff if it can’t complete a minute-long orbital insertion burn. In the case of OFT-2, that burn came about 31 minutes after liftoff and was thankfully successful, inserting Starliner into a stable, circular orbit and undoubtedly triggering a massive wave of relief for all employees involved. From that stable orbit, Starliner can finally begin to prepare to rendezvous with the International Space Station (ISS) for the first time ever.
The story of Starliner’s tortured orbital flight test (OFT) campaign began in earnest on December 20th, 2019, when an uncrewed prototype of the Boeing spacecraft first attempted to launch to the International Space Station (ISS) atop a United Launch Alliance (ULA) Atlas V rocket. Infamously, a major software bug that could have been easily detected with even the most basic integrated hardware-in-the-loop prelaunch testing caused Starliner to lose control the moment it separated from Atlas V. Only through a heroic last-second effort was Boeing able to insert Starliner into orbit and prevent the spacecraft from reentering prematurely, which would have likely destroyed it. After hundreds of seconds of unplanned burns of its many attitude control thrusters, Starliner no longer had enough propellant to safely reach the ISS.
Boeing would later correct another completely unrelated software bug mere hours before Starliner’s planned reentry and recovery. If undetected, it could have caused the spacecraft’s capsule and service sections to crash into each other shortly after separation, potentially damaging the capsule’s heat shield and dooming it to destruction during reentry. Had astronauts been aboard, either of the two software bugs could have potentially resulted in crew fatalities and total mission failure. Instead, through a combination of sheer luck and a quick emergency response from Boeing and NASA teams, the spacecraft was saved and recovered in New Mexico.
On a positive note, aside from raising deep and foreboding questions about Boeing’s software development and integrating testing capabilities and NASA’s inept and inconsistent oversight, OFT-1 did still demonstrate that Starliner was able to reach orbit, operate in space, deorbit, survive atmospheric reentry, and land softly under parachutes.
However, the problems were about to continue and spread beyond software. On July 30th, 2021, shortly before a different uncrewed Starliner was scheduled to reattempt the first Orbital Flight Test, the launch was aborted. Eventually, Boeing and NASA reported that 13 of Starliner’s 24 main oxidizer valves had failed to open during a prelaunch test just a few hours before liftoff. The resulting investigation ultimately concluded that the Aerojet Rocketdyne-supplied valves had a faulty design and that Boeing had failed to properly insulate those valves from humidity and water intrusion. It also delayed the next OFT-2 launch attempt by almost ten months.
But finally, after almost 30 months of work to rectify those software and hardware failures, Starliner has intentionally reached a stable orbit without running into a major problem – certainly cause for some amount of optimism. Still, safely rendezvousing and docking with the ISS may be the biggest and riskiest challenge Starliner has faced yet and Boeing will be attempting the feat for the first time in its modern history. Starliner is expected to begin proximity operations around 3 pm EDT on May 20th. If the first attempt is perfect, docking could occur as early as 7:10 pm EDT.
Ultimately, even if Boeing is now more than three years behind SpaceX, whose Crew Dragon spacecraft first reached orbit and the ISS in March 2019 and launched its first astronauts in May 2020, it’s essential that NASA has two redundant crew vehicles available to carry its astronauts to and from the station. SpaceX’s extraordinary success and heroic efforts have allowed the company to singlehandedly ensure NASA access to the ISS since November 2020, but no complex system is perfect and even a failure outside of SpaceX’s control could trigger a long delay that could threaten NASA’s uninterrupted presence on the International Space Station.
NASA has contracts with SpaceX to maintain that uninterrupted presence at the ISS through Crew Dragon’s Crew-7 mission, which could launch as early as September 2023 and would then return to Earth around March 2024. If OFT-2 is completed without significant issue, Boeing’s next priority is Starliner’s Crew Flight Test (CFT), a crewed launch debut that could happen before the end of 2022.
After that, Starliner’s first operational crew launch could potentially occur in Q1 2024, just before Crew Dragon’s Crew-7 recovery. Following Crew Dragon’s near-flawless uncrewed test flight, it took another 14 months for NASA and SpaceX to proceed to Demo-2, Dragon’s Crew Flight Test equivalent. Dragon’s first operational astronaut launch occurred in November 2020, 20 months after its uncrewed demo flight. If NASA follows a similar path for Starliner, that meshes well with an operational debut in early 2024.

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 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.
