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.

SpaceX’s amended S-1 is sparking a major Tesla merger conversation
A single line in SpaceX’s amended S-1 just sent Tesla stock down 5% in one day.
A single line buried in SpaceX’s amended S-1 filing is doing more to move Tesla’s stock price than anything Tesla itself has announced in months. The clause, disclosed as SpaceX prepares for what could be the largest IPO in Wall Street history, states that the company “may issue a significant amount of equity in connection with future transactions.” While this may be seen as boilerplate language in S-1 filings, the historical ties between SpaceX and Tesla, and with Elon Musk reportedly discussing a possible merger with close colleagues, investors are interpreting it as something closer to a signal.
The concern among institutional investors like Gary Black, managing director of The Future Fund, pointed directly to the amended filing on X, saying it “strongly suggests more SPCX equity will be issued,” which could potentially be used to acquire Tesla. He estimated such a deal could be 28% dilutive to Tesla shareholders since SpaceX would likely command a significantly higher valuation multiple. Black added that institutional investors he knows hate the idea of a combination because they prefer pure plays over conglomerates, which he said “nearly always gravitate to the lowest common multiple.”
The Tesla and SpaceX merger everyone is talking about is quietly building
The bull case runs the math differently. Tesla influencer and retail shareholder advocate AleXandra Merz pushed back on what she called a widespread misunderstanding of how merger-of-equals deals actually work. Rather than simply splitting the difference between two market caps, a merger exchange ratio is negotiated based on relative fair market values, meaning the lower valued company typically sees its stock reprice upward toward the deal value.
Under her model, SpaceX enters at a $2.5 trillion valuation and Tesla at $1.6 trillion, producing a combined entity worth $4.1 trillion split evenly between both shareholder groups. That implies Tesla’s side of the deal would be valued at $2.05 trillion, a gain of roughly $450 billion from its current market cap. She cited Dow-DuPont and CBS-Viacom as historical examples of how markets reprice both companies toward the announced exchange ratio after a deal is unveiled.

The SpaceX S-1 amendments also revealed just how much financial infrastructure already binds the two companies together. As Teslarati has reported, SpaceX purchased $697 million in Tesla Megapacks, $131 million in Cybertrucks, and the two companies have shared supply chain resources, and semiconductor fabrication plans since well before any merger conversation became public. A retail poll by Tesla influencer Sawyer Merritt is finding that 36% of respondents do not plan to buy SpaceX shares at IPO and 15.3% saying their decision depends on the valuation.

Whether the merger happens or not, the amended filing is seemingly moving markets and sharpened a debate that is no longer theoretical. SpaceX is weeks away from trading publicly, and Tesla shareholders are now watching every word of every filing for clues about what Musk plans to do next.
Tesla is staging a powerful rebound in Europe. New vehicle registrations surged dramatically across multiple key markets in May 2026, signaling a strong recovery from the challenges of 2025.
Data released this week show double- and triple-digit year-over-year gains in several countries, driven by refreshed Model Y production, supportive policies, high fuel prices, and renewed consumer interest in electric vehicles.
In France, registrations exploded 655 percent to 5,446 vehicles, marking Tesla’s best May performance ever in the country. Norway, a longtime EV stronghold, saw 3,345 new Teslas registered, up 29 percent from May 2025. The company even captured a commanding 21.5 percent market share there, according to Detroit News.
Growth extended to other markets as well. Sweden posted a 71 percent increase to 858 registrations. Denmark jumped 136 percent to 1,750 units, where the Model Y became the top-selling vehicle overall. Spain climbed 113 percent to 1,690 sales, while Portugal soared nearly 350 percent to 1,463.

Tesla Full Self-Driving expansion in Europe continues with new addition
The May results build on a broader turnaround for Tesla in Europe. The company’s sales on the continent had declined sharply in 2025, dropping between 27 and 28 percent amid production shifts, intense competition from Chinese rivals like BYD, and shifting consumer sentiment.
Early 2026 showed signs of life, with registrations rising about 45 percent across Europe in the first quarter and continuing upward momentum through April, up over 46 percent region-wide.
Europe’s overall electrified vehicle market (including BEVs, PHEVs, and hybrids) grew about 21 percent in May, providing a favorable tailwind. Tesla’s gains align with this trend, boosted by government incentives and high fuel costs that make EVs more attractive.
Earlier data from March and April already hinted at strength in Germany, where registrations had surged dramatically in prior months.
Analysts note that while competition remains fierce, Tesla’s refreshed lineup and Europe’s policy support for EVs are helping the company regain ground. The May surge suggests the worst of the 2025 downturn may be behind it, positioning Tesla for stronger performance in the second half of 2026.
This rebound is welcome news for the EV pioneer, demonstrating resilience in a competitive and evolving market. As more data rolls in, investors and industry watchers will be closely monitoring whether this momentum can sustain through the summer and beyond.
Tesla is planning to improve one of the best features on its lineup of cars, a new patent shows. Tesla’s massive glass roof on its premium models is among the coolest additions to the all-electric vehicles, but the design certainly has its complaints, especially from those who live in even slightly warm climates.
Tesla has published a new patent that promises to transform cabin comfort in its electric vehicles, particularly those equipped with the expansive glass roofs.
The document, identified as US20260091643A1 and titled “Airflow Optimization for Cabin Comfort“, addresses that common complaint. Sunlight streaming through windshields and panoramic roofs creates localized hot air pockets near the dashboard and headliner. These pockets generate significant temperature gradients that conventional heating, ventilation, and air conditioning systems struggle to manage evenly.
The exposure to direct sunlight can make the cabin extremely warm, and even after cooling down the interior temperature, combating the continuous stream of sunlight and heat is a challenge. It uses precious energy that is especially pertinent to range and efficiency.
The patent explains how standard dashboard vents push cool air upward, only to entrain warmer air from these stagnant zones and distribute it throughout the occupied cabin space. This process forces the blower to operate at higher speeds, increasing energy consumption and reducing overall efficiency.
In electric vehicles, where every watt impacts driving range, such inefficiencies prove costly.

Research from AAA indicates that air conditioning can diminish range by up to 17 percent under hot conditions. Tesla’s innovation shifts the approach by extracting heat at its source rather than attempting to dilute it after mixing occurs.
Engineers describe a suction HVAC unit connected to dedicated intakes positioned strategically on the upper dashboard surface and within the headliner.
These intakes link to a hot air pocket extraction duct that channels the warmest air directly into the system’s plenum for conditioning. As the blower activates, it simultaneously draws recirculated cabin air and targeted hot pocket air through filters and cooling coils before redistributing conditioned airflow.
It seems somewhat reminiscent of the Tesla heat pump, which aims to combat colder temperatures.

This method reduces entrainment, lowers peak temperatures, and achieves more uniform comfort levels. Testing data reveals that facial temperature gradients drop from 21 degrees Celsius, or 69.8 degrees Fahrenheit, in conventional setups to just 12 degrees Celsius (53.6 degrees F) with the new system. Blower speeds and compressor power requirements decrease appreciably as a result.
The design incorporates smart controls that monitor sunlight intensity and internal temperature distributions in real time. Suction activates selectively only where needed, optimizing energy use without constant high demand. Furthermore, the extraction duct serves a dual purpose.
In the summer months, it pulls hot air inward for cooling; in winter, it reverses to direct warm air outward for rapid windshield defrosting. This versatility allows the reuse of existing hardware with minimal modifications, potentially enabling retrofits in current Tesla fleets.
