Elon Musk reveals SpaceX Falcon 9 survived a water landing test
Following the picture-perfect launch of GovSat-1 on Wednesday afternoon, SpaceX CEO Elon Musk took to Twitter with an extremely unusual bit of news. After separating from the second stage, events relating to Falcon 9’s first stage recovery operations were heard live in the background of SpaceX’s live coverage, leading to some additional intrigue around an already odd situation.
B1032, a flight-proven (reused) booster tasked with launching GovSat-1 on its second mission, was seen with landing legs and grid fins on its sooty exterior – a confusing appearance due to SpaceX’s statement that the core would be expended into the ocean after launch. Thankfully, Elon Musk’s tweets provide at least the beginning of an answer for the several oddities.

As stated above, GovSat-1’s Falcon 9 booster (1032) was apparently being used to test an exceptionally aggressive landing burn in lieu of a drone ship beneath it. The lack of drone ship begins to make more sense with the added knowledge that 1032 was testing experimental landing procedures: in the relatively likely eventuality that something went wrong, the massive booster would have likely impacted Of Course I Still Love You at an extremely high velocity. Similar impacts have occurred before as SpaceX gradually perfected the new technologies and operational knowledge necessary to recover orbital-class rockets, but a basic understanding of rocketry implies that 1032’s OCISLY impact would have been uniquely destructive, likely taking the ship out of action for at least several weeks of repairs.
This would pose an inherent problem for the imminent launch of Falcon Heavy, with the center of three first stages currently scheduled to attempt a landing aboard the very same drone ship in less than a week. Under optimum conditions (sans huge explosions and general destruction), OCISLY and its entourage of support vessels simply could not complete the journey back to Port Canaveral and the subsequent return to sea that would have been necessary to recovery both GovSat-1 and Falcon Heavy’s center core. Add in the potential need for repairs and expending GovSat-1 was a no-brainer for the launch company: Falcon Heavy’s center core could easily see at least one additional launch after it is recovered, whereas the twice-used 1032 effectively reached the end of its useful life after it separated from the second stage and GovSat payload earlier today.

As a result, SpaceX appears to have continued a trend of exploiting flight test opportunities to the greatest extent practicable by tasking B1032 with an experimental landing attempt. More specifically, Elon quickly added that the landing burn attempted by 1032 involved the ignition of three of the booster’s nine Merlin 1D engines during landing, whereas all SpaceX landings up to this point have occurred with a single Merlin 1D ignition. While the company already routinely utilizes three engines during some boostback and reentry burns, landing burns have always featured a single engine. However, by using three engines, it is entirely possible that SpaceX hopes to eventually move towards even more aggressive landing burns. While the obvious downsides likely include difficulty maintaining control and increased stresses on the booster, the benefits are also pretty inherent. By using more engines, the length of the landing burn could be drastically shortened, resulting in far more efficient propellant usage by minimizing losses to gravity (every second the rocket is trying to go upwards is a second fighting against Earth’s gravity, which pulls the rocket down at ~9.8 meters/second squared).
Incredibly, the booster somehow managed to pull off that three engine landing burn with some success, made apparent by the fact that it is intact and floating in the Atlantic, with some hope of being towed back to land. This is almost certainly the first time SpaceX has ever successfully landed a booster in the ocean without a subsequent breakup, an incredible achievement for a rocket that likely experienced exceptional stresses during reentry and landing. Time will tell how this impacts SpaceX’s future recovery efforts, but it is certainly promising as a method of extracting just a little extra performance from reusable Falcon 9s. In other words, future Falcon 9 missions might be able to carry heavier payloads into higher orbits while still being able to land at sea or even on land. Exciting times!

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.
