SpaceX continues water landing test in latest Space Station resupply mission
SpaceX has completed their second launch in less than four days, and the company’s 14th Cargo Dragon mission has successfully made it to a safe parking orbit where it will make its way to the International Space Station over the next two days.
Carrying nearly 5,800 pounds of perishables, experiments, and scientific equipment to be bolted to the outside of the ISS, this particular Cargo Dragon flew once before in 2016, while the booster that lifted it above Earth’s thin atmosphere was tasked with launching CRS-12 in August 2017. According to Jessica Jensen, SpaceX’s Director of Dragon Mission Management, this particularly Dragon capsule was the first to fly with upgraded water sealing, meaning that it was considerably easier (and thus cheaper) for SpaceX to refurbish and refly. The only items that had to be replaced this time around were the heatshield, trunk, and parachutes, and this experience will undoubtedly translate into Dragon 2 (Cargo Dragon), likely ensuring exceptional reuse characteristics for that the company’s next-gen capsule.

Sadly, CRS-14’s doubly flight-proven launch also marked yet another expended booster – B1039 happened to be the first Block 4 version of Falcon 9’s stage to fly a mission. Jensen described that SpaceX – accustomed to making these decisions on a case-by-case basis – had chosen to expend this particular booster after concluding that the benefits of testing extreme booster trajectories and recovery profiles outweighed the difficulty (and cost) of refurbishing a Block 4 booster for a third launch. In this case, B1039 would have been the best option if SpaceX had any desire to fly a booster more than twice before the introduction of the purpose-driven, next-generation Block 5 reusability upgrade – Block 4 was clearly not built to fly more than twice without an uneconomical amount of refurbishment.

While no specific details were given and live coverage shown of the soft-landing, it’s presumed that B1039 continued in the footsteps of water landings that followed GovSat-1 and Hispasat 30W-6 in January 2018 and March 2018. These uniquely aggressive landing attempts are all believed to have ignited three Merlin 1D engines rather than the single engine typically ignited for landing burns, providing a more efficient use of propellant reserves at the cost of extreme acceleration (G) forces and far slimmer margins of error. The ultimate promise of these tests, if successful, is to allow SpaceX the option of recovering boosters during missions with heavier payloads and higher orbits.

The imminent NET April 24 inaugural launch of SpaceX’s rapid reuse Falcon 9 “Block 5” will mark the beginning of a new era of rocketry for SpaceX, where expendable missions are likely to become a rarity. Expending a single Block 5 booster could fairly be perceived as throwing away the potential revenue and income from anywhere from 5-100 future re-flights. As such, SpaceX has every reason to expend non-Block 5 boosters with the hope of ensuring that fewer new-generation rockets end up expended after launch.

Intriguingly, Jensen also noted in a prelaunch briefing that SpaceX’s Cargo Dragons are certified for as many as three orbital reuses – a possibility as SpaceX steps towards completing all 20 of its contracted CRS-1 missions, the final five of which are scheduled to resupply the ISS between now and early 2020. After the final CRS-1 launch, NASA has already awarded SpaceX and Orbital ATK contracts for CRS-2, a second Commercial Resupply Services contract that will begin in 2020 and fly on OATK’s upgraded Cygnus and SpaceX Dragon 2, potentially repurposing recovered Crew capsules in the case of SpaceX.
Up next on the SpaceX calendar are a number of conferences and presentations over the next two or three weeks, followed by SpaceX NASA TESS mission on April 16 and the debut of Falcon 9 Block 5 for the launch of Bangabandhu-1, April 24. SES-12 may be launched sometime in early May or late April, and the next West coast launch of Iridium-6/GRACE-FO is expected to occur NET May 10.

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 crushes NHTSA’s brand-new ADAS safety tests – first vehicle to ever pass
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 to fix 219k vehicles in recall with simple software update
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.
