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 gets strange-but-understandable comparison from Jay Leno

The Tesla Semi recently received a strange-but-understandable comparison from automotive enthusiast and former long-time late-night television show host Jay Leno.
In a recent interview with MotorTrend, legendary comedian and automotive enthusiast Jay Leno shared his impressions after driving Tesla’s long-range Semi truck, offering one of the most vivid descriptions to date:
“It’s like driving an office building.”
The comparison may seem quirky—office buildings evoke images of immobility rather than motion—but it aptly conveys the experience of commanding a massive 23,000-pound Class 8 electric truck that delivers sports-car acceleration.
Lenotested the production-spec Long Range model, which is rated for up to 500 miles of range. He was visibly impressed by its performance, noting how the enormous vehicle moves with surprising urgency.
“It’s as fast as a Tesla, but it’s like driving an office building,” he remarked. “It’s this huge thing that moves like right now. You go 500 miles. You get 60% charge in 30 minutes. You’re saving on fuel costs. It seems quite good.”

The reaction highlights the cognitive dissonance at the core of the Tesla Semi. Traditional diesel semi-trucks are slow, noisy, and expensive to run. The Semi rewrites the rules with instant torque from its tri-motor electric powertrain, producing up to 800 kW.
Despite its size, the truck feels agile thanks to full electric steering assist, upgraded actuators borrowed from the Cybertruck, and a 48-volt electrical architecture that improves responsiveness and efficiency.
Tesla reports real-world energy consumption below 1.7 kWh per mile for the Long Range version. Megacharger stations can deliver a 60% charge in roughly 30 minutes, making the truck suitable for long-haul operations.
Additional features include an electric Power Take-Off (ePTO) capable of 25 kW for trailer refrigeration or other equipment, and a driver-focused cab with a central seating position for optimal visibility and a quiet, high-tech interior.
Fleet operators stand to benefit significantly from the economics. Diesel trucks often cost nearly one dollar per mile when including fuel, maintenance, and downtime.
Tesla projects the Semi can reduce operating costs to as low as 15 cents per mile through cheaper electricity, regenerative braking that minimizes brake wear, and reduced service requirements. While early deployments, like Pepsi’s, focused on shorter routes, the 500-mile variant targets cross-country applications.
Obstacles remain. A fully loaded tractor-trailer can reach 80,000 pounds, which reduces real-world range compared to the unloaded test conditions. Building out a nationwide Megacharger network will be essential for broader adoption. The Semi also carries a higher upfront price than conventional diesels, though total cost of ownership and available incentives frequently tip the scales in its favor over time.
Tesla Semi hauls fresh Cybercab batch as Robotaxi era takes hold
Leno’s “office building” description resonates because it captures the unexpected thrill of piloting something so large yet so capable. As the trucking industry faces pressure to cut emissions and control rising fuel expenses, the Semi offers a compelling alternative that excels in performance, comfort, and efficiency.
Coming from a man who has driven everything from vintage classics to modern hypercars, Leno’s genuine enthusiasm adds weight to the verdict.
The Tesla Semi is emerging as more than an experimental EV—it represents a practical vision for the future of heavy-duty transport where massive rigs accelerate instantly, and the numbers finally make sense. If fleet results continue to validate the claims, the era of diesel dominance could be drawing to a close.

Tesla expands its mass-market color palette in the U.S.
Delivering a fresh splash of color to its lineup, Tesla is giving U.S. buyers two stunning new blue options that are already turning heads.
Tesla has expanded the color palette it offers on its mass market vehicles in the United States, giving buyers of the Model 3 and Model Y a few additional options than before.
Delivering a fresh splash of color to its lineup, Tesla is giving U.S. buyers two stunning new blue options that are already turning heads. Starting on May 8, the automaker updated its North American configurator to introduce Marine Blue on Model Y Premium trims and Frost Blue exclusively on the Model 3 Performance.

The move replaces the long-running Deep Blue Metallic, a staple for over eight years, and brings previously exclusive shades stateside.
Marine Blue, a deep, rich oceanic hue formerly limited to Europe and Asia-Pacific markets, is now available on Model 3 and Model Y RWD and Long Range AWD Premium variants. Priced at a $1,000 upgrade—standard for Tesla’s premium paints—it delivers a sophisticated, metallic finish that shifts beautifully under light.

Tesla North America highlighted the change directly in an official post, confirming Marine Blue as the new flagship blue for non-Performance models.
Frost Blue, on the other hand, is the real crowd-pleaser for enthusiasts. Previously reserved for the flagship Model S and Model X, this lighter, icy metallic shade is now offered at no extra cost on Model 3 Performance and Model Y Performance trims.

Performance buyers effectively get a premium color included in the base price, a smart perk that Tesla has extended to higher-end variants across the board. Early in-person sightings and configurator renders show Frost Blue’s cool, modern vibe popping against the cars’ sleek lines, especially with black wheels and red brake calipers.
The timing couldn’t be better. With Tesla pushing refreshed Model 3 and Model Y refreshes amid growing competition, these updates add visual excitement without major redesigns.
Deep Blue Metallic orders are being transitioned to the new shades, according to customer reports and Tesla communications. In the U.S., Puerto Rico, and Mexico, the options are live now; Canada sees limited Frost Blue availability on the Model 3 Performance.
Tesla’s color strategy continues to evolve, borrowing from higher-end models to refresh mass-market EVs. Now that we bid farewell to the Model S and Model X, some of their colors might be available on the more widely available Model 3 and Model Y.

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.
