NASA officially says goodbye to Mars Opportunity rover lost in massive dust storm
After 15 years roving around our neighboring red planet, NASA announced the end of its Opportunity rover mission on Mars today during a live conference held at 2 pm EST. The rover’s team of scientists spent last night sending a set of commands intended to be the last attempt at waking Opportunity, and this afternoon’s announcement confirmed the final fate of the mission. A planet-wide dust storm in summer of 2018 shut the Martian rover down due to its solar panels being blocked from debris, and the long duration spent without power apparently led to a series of failures which prevented a recovery. The last communication NASA received from Opportunity was on June 10, 2018.

Over the last few months, while scientists continued to revive Opportunity, hopes were fairly high that communication would be reestablished. The rover’s batteries were in good health prior to the dust storm, and the surface temperature was relatively warm when the storm began. Also, its programming was designed with “fault modes” allowing actions to be taken automatically to maintain the rover’s health. The team at NASA had attempted to talk to Opportunity several times per week once the storm began to clear using the Deep Space Network, an international array of giant radio antennas supporting interplanetary spacecraft missions, and over 600 attempts were made without any response received. The announcement was broadcast live via NASA’s website.
Emotions were high during NASA’s mission end announcement. Associate NASA Administrator Thomas Zurbuchen began the event’s commentary: “I stand here, surrounded by the team…it’s an emotional time,” he began. “Science is a team sport, and that’s what we’re celebrating today.” NASA Administrator Jim Bridenstine noted that while Opportunity stopped communicating around the same time be began his service with the administration, he was still in awe at the achievements the rover and its team were able to achieve throughout their mission. “When this little rover landed, the objective was to have it move 1100 yards and survive for 90 days,” he exclaimed before reiterating the unexpected 15 years the mission eventually lasted. Michael Watkins, Director of NASA’s Jet Propulsion Laboratory commented on the mission’s broader contribution to society: “Spirit and Opportunity energized the public about the spirit of Mars exploration.”
John Callas, project manager of NASA’s Mars Exploration Rover (MER) project, provided some insight about what could have caused Opportunity to shut down for good. Earlier in Opportunity’s mission days, a heater on its robotic arm failed to turn off, draining the rover’s energy in the process. To overcome this issue, the team at NASA designed a deep sleep mode which shut down nearly everything on Opportunity, including the heater. Callas surmised that the dust storm which ended the rover’s mission may have disrupted its sleep cycle, reinstating the power draining issue and preventing recovery. He also described the quality of Opportunity’s batteries and the seasonal reliability of the Martian winds to clean its solar panels as part of the reasons it lasted as long as it did. Finally, Callas had his own farewell comments to add. “Even though it’s a machine, saying goodbye, it’s very hard and very poignant,” he remarked.

NASA’s Opportunity rover (nicknamed “Oppy”) launched on July 7, 2003, aboard a Delta II rocket from Cape Canaveral, Florida. Its primary mission was to search for and characterize rocks and soil while looking for indications of water activity in the Martian past. One of the better-known discoveries made by the rover was the discovery of hematite on the surface, a mineral which typically forms in water. Also found were strips of gypsum in rocks around a crater, indicating that water most likely flowed through the area at one point. The storm which finally ended the rover’s mission was intense and massive, its size is roughly the area of North America and Russia combined with Opportunity in the center.
A month prior to Opportunity’s launch, its twin rover Spirit headed for Mars with a similar mission. Both rovers lasted years longer than their 90-day expected life span, but unfortunately, Spirit’s mission ended before Opportunity’s when it became lodged in soft soil at a site called “Troy”. NASA ended its rescue effort of Spirit in May 2011. Another NASA rover named Curiosity is still crawling the planet, however. Its plutonium-nuclear power source helped it avoid the same fate that came over its predecessor, even sending back a storm-riding selfie during the event that claimed Opportunity.
NASA’s most recent mission to Mars was its InSight lander, a geological science mission sent to study the core of the planet and atmosphere. After arriving at the red planet in late November 2018 with twin CubeSat mission MarCo, it successfully landed without incident and sent a dusty photo back for Earthling enjoyment and arrival confirmation. In the months since it’s treated NASA and the public alike with selfies and the sound of Martian wind. Its instruments have recently been placed on the surface, so new planet data is expected soon.
Up next for the fourth rock from the Sun will be Mars 2020, an advanced rover dedicated to high-priority science missions including the search for habitable conditions and microbes in the ancient past. NASA plans to launch this rover in July 2020.

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.
