SpaceX expends Falcon 9 booster for the first time in almost three years
For the first time since January 2020, SpaceX has intentionally expended a Falcon 9 booster instead of attempting to recover the rocket at sea or on land.
Weighing around 6.6 tons (~14,600 lb) at liftoff, the rare mission sent Intelsat’s twin Maxar-built Galaxy 31 and 32 communications satellites to a high geostationary transfer orbit (GTO) that will allow them to start operating more quickly than a standard GTO would. To launch such a heavy payload to such a high ‘supersynchronous’ transfer orbit, SpaceX – at Intelsat’s request and for a fee – removed all landing-related hardware from Falcon 9 and did not attempt to recover the first stage.
Instead, the rocket put all the propellant that would have otherwise been saved for recovery into its first and only burn, reaching as high a speed as possible before separating from the second stage. Flying for the 14th time since its March 2019 debut, Falcon 9 booster B1051 didn’t perform a controlled flip or attempt to land on a SpaceX drone ship. It’s more likely that the few-dozen-ton rocket – now drained of propellant – reentered Earth’s atmosphere with no control at a speed of roughly 2.7 kilometers per second (~6000 mph), broke apart when it slammed into that atmospheric ‘wall,’ and crashed into the Atlantic Ocean as a cloud of debris.
Having already flown 13 times before its 14th and final mission, it’s safe to say that booster B1051 earned its permanent retirement as an artificial reef. The mission marked the first time a Falcon 9 booster was intentionally discarded since January 2020, when the first Falcon 9 Block 5 booster – B1046 – was destroyed as part of an intentional In-Flight Abort test of SpaceX’s Crew Dragon spacecraft.
Like B1046, B1051 was another fairly new Falcon 9 Block 5 booster. It’s no coincidence that most of the first five or so boosters have been or will be intentionally expended. B1047 was first in August 2019, followed by B1046 five months later, and B1051 in November 2022. B1048 and B1050 both suffered in-flight anomalies that – while they didn’t impact the success of their primary missions – resulted in failed landing attempts. After B1051’s demise, only B1049 remains. Next Spaceflight reports that SpaceX will also intentionally expend that booster after its 11th launch, which will send the Eutelsat 10B communications satellite to a different geostationary transfer orbit as early as this month..
While SpaceX likely charged its customers a healthy fee to expend B1049 and B1051, the company is likely not complaining about an opportunity to refine its fleet of Falcon boosters. Though no new variant has been officially introduced, SpaceX has learned more about the design over the years, and newer Falcon Block 5 boosters include improvements that make them easier and cheaper to operate and reuse. It’s also added four new Falcon 9 boosters to the fleet in less than a year, easing the burden created by expending two older but flightworthy boosters weeks apart.
Once B1049 is gone, that fleet will still have one unflown Falcon 9 booster, four unflown Falcon Heavy boosters, ten flown Falcon 9 boosters, and four flown Falcon Heavy side boosters – the latter of which can potentially be converted into Falcon 9 boosters during Falcon Heavy lulls. B1051 was the third Falcon 9 booster to complete 14 launches, meaning that SpaceX has gotten so good at routine reusability that it can safely assume that each new Falcon 9 Falcon Heavy side booster can fulfill the roles of more than a dozen expendable boosters.
Ultimately, B1051’s sacrifice left Falcon 9’s expendable upper stage with enough performance to boost Galaxy 31 and 32 into a supersynchronous orbit with an apogee more than 58,400 kilometers (~36,300 miles) above Earth’s surface – almost 1.5 times its circumference. Just last month, two recoverable Falcon 9 boosters helped launch a pair of smaller 4.5-ton (~10,000 lb) satellites to almost identical orbits (~57,500 km vs. ~58,400 km). Expending Falcon 9’s booster thus allowed SpaceX to launch almost 50% more payload to a similar supersynchronous GTO, demonstrating the substantial toll booster reuse incurs on launches to higher orbits.
Galaxy 31/32 was SpaceX’s 52nd launch this year and hit a target set by CEO Elon Musk in January. Musk later raised his goal to 60 launches, but SpaceX has managed an average of one Falcon launch every six days for nearly 12 months and has a strong shot at completing another eight launches before the end of the year.

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.
Tesla became the first company to pass the United States government’s new Advanced Driver Assistance Systems (ADAS) testing with the Model Y, completing each of the new tests with a passing performance.
In a landmark announcement on May 7, the National Highway Traffic Safety Administration (NHTSA) declared the 2026 Tesla Model Y the first vehicle to pass its newly ADAS benchmark under the New Car Assessment Program (NCAP).
Model Y vehicles manufactured on or after November 12, 2025, met rigorous pass/fail criteria for four newly added tests—pedestrian automatic emergency braking, lane keeping assistance, blind spot warning, and blind spot intervention—while also satisfying the program’s original four ADAS requirements: forward collision warning, crash imminent braking, dynamic brake support, and lane departure warning.
The NHTSA has just officially announced that the 2026 @Tesla Model Y is the first vehicle model to pass the agency’s new advanced driver assistance system tests.

NHTSA administration Jonathan Morrison hailed the achievement as a milestone:
“Today’s announcement marks a significant step forward in our efforts to provide consumers with the most comprehensive safety ratings ever. By successfully passing these new tests, the 2026 Tesla Model Y demonstrates the lifesaving potential of driver assistance technologies and sets a high bar for the industry. We hope to see many more manufacturers develop vehicles that can meet these requirements.”
The updates to NCAP, finalized in late 2024 and effective for 2026 models, reflect growing recognition that ADAS features are no longer optional luxuries but essential tools for preventing crashes.
Pedestrian automatic emergency braking, for instance, targets one of the fastest-rising causes of roadway fatalities, while blind spot intervention and lane keeping assistance address common sources of side-swipes and run-off-road incidents. By incorporating objective, performance-based evaluations rather than mere presence of the technology, NHTSA aims to give buyers clearer data on real-world effectiveness.
This milestone arrives at a pivotal moment when vehicle autonomy is transitioning from science fiction to everyday reality.
Tesla’s Full Self-Driving (FSD) software and the impending rollout of robotaxis underscore a broader industry shift toward higher levels of automation. Yet regulators and consumers remain cautious: safety data must keep pace with technological ambition.
The Model Y’s perfect score on these ADAS benchmarks validates that current driver-assist systems—when engineered rigorously—can dramatically reduce human error, which still accounts for the vast majority of crashes.
For Tesla, the result reinforces its long-standing claim of building the safest vehicles on the road. More importantly, it signals to the entire auto sector that meeting elevated federal standards is achievable and expected.
As autonomy edges closer to Level 3 and beyond, where drivers may disengage more fully, such independent verification becomes critical. It builds public trust, informs purchasing decisions, and accelerates the development of systems that could one day eliminate tens of thousands of annual traffic deaths.
In an era when software-defined vehicles promise transformative mobility, the 2026 Model Y’s NHTSA triumph is more than a manufacturer accolade—it is a regulatory green light that autonomy’s future must be built on proven, testable safety foundations. The bar has been raised. The industry, and the roads we share, will be safer for it.
Tesla is going to fix the nearly 219,000 vehicles that it recalled due to an issue with the rearview camera with a simple software update, giving owners no need to travel to a service center to resolve the problem.
Tesla is formally recalling 218,868 U.S. vehicles after regulators discovered a software glitch that can delay the rearview camera image by up to 11 seconds when drivers shift into reverse.
The affected models include certain 2024-2025 Model 3 and Model Y, as well as 2023-2025 Model S and Model X vehicles running software version 2026.8.6 and equipped with Hardware 3 computers. The National Highway Traffic Safety Administration (NHTSA) determined the lag violates Federal Motor Vehicle Safety Standard 111 on rear visibility and could increase crash risk.
Yet this is no ordinary recall. Owners do not need to schedule a service-center visit, hand over keys, or wait for parts.
Tesla fans call for recall terminology update, but the NHTSA isn’t convinced it’s needed
Tesla identified the issue on April 10, halted further deployment of the faulty firmware the same day, and began pushing a corrective over-the-air (OTA) software update on April 11.
By the time the NHTSA posted the recall notice on May 6, more than 99.92 percent of the affected fleet had already received the fix. Tesla reports no crashes, injuries, or fatalities linked to the glitch.
The episode underscores a deeper problem with regulatory language. For decades, “recall” meant hauling a vehicle to a dealership for hardware repairs or replacements. That definition no longer fits software-defined cars. When a fix arrives wirelessly in minutes — identical to an iPhone update — the term evokes unnecessary alarm and misleads the public about the actual risk and remedy.
Elon Musk has repeatedly called for exactly this change. After earlier NHTSA actions, he stated plainly: “The terminology is outdated & inaccurate. This is a tiny over-the-air software update.” On another occasion, he added that labeling OTA fixes as recalls is “anachronistic and just flat wrong.”
The terminology is outdated & inaccurate. This is a tiny over-the-air software update. To the best of our knowledge, there have been no injuries.
— Elon Musk (@elonmusk) September 22, 2022
Musk’s point is simple: regulators must evolve their vocabulary to match the technology. Traditional recalls involve physical intervention and downtime; OTA updates do not. Retaining the old label distorts consumer perception, inflates perceived defect rates, and slows the industry’s shift to faster, safer software iteration.
Tesla’s rapid, remote remedy demonstrates the safety advantage of over-the-air capability. Problems that once required weeks of dealer appointments are now resolved in hours, often before most owners notice. As more automakers adopt software-first designs, the entire regulatory framework needs to catch up.
Updating “recall” terminology would align language with reality, reduce public confusion, and recognize that modern vehicles are no longer static hardware — they are continuously improving computers on wheels.
For the 219,000 Tesla owners involved, the process is already complete. The camera works, the car is safe, and no one left their driveway. That is the new standard — and the vocabulary should reflect it.
