NASA has deployed a small dome on Mars to protect its “marsquake” detector
Before NASA’s InSight lander gathers data on Martian surface vibrations, aka “marsquakes”, it needs to protect its seismographic instrument from the winds and temperature changes during its stay on the red planet. Since wild temperature swings on Mars can mean fluctuations of about 170 degrees Farenheit over the course of a Martian day (sol), contractions and expansions of the seismometer were a problem needing to be addressed. To do that, an instrument shield was designed which has now been deployed as a first line of defense: It’s a white dome with a chain mail and thermal blanket skirt on the bottom called the “Wind and Thermal Shield”. After a successful dome deployment on Saturday, another milestone for the craft has been reached, bringing InSight’s team one step closer to understanding the secrets of the planet’s early formative years by studying its core.
InSight (short for “Interior Exploration using Seismic Investigations, Geodesy and Heat Transport”) was launched aboard an Atlas rocket in California on May 5, 2018, arriving at its destination on November 26, 2018. After a perfect live-streamed Martian surface landing shortly thereafter, Earthlings were treated to a (slightly dusty) photo taken by one of InSight’s on-board cameras, providing visual confirmation of the arrival. In the following days and weeks, ‘selfies’ along with other goodies were sent, such as the sound of Martian wind, as the craft meticulously placed its seismometer on the ground and continued its preparation for its full science mission of studying the heart of Mars as well as its atmosphere and weather patterns.
In addition to a protective dome, InSight’s seismometer itself adjusts for the changing Martian surface. As some parts expand and contract, other parts do the reverse to balance out the effect. Inside the dome, the seismometer is also contained in a titanium, vacuum-sealed container, the combination of which helps insulate the instrument even further from environmental hazards. The high-carbon dioxide content of Mars’s atmosphere is slow to conduct heat under the planet’s low pressure environment, further protecting InSight’s mission from local damaging effects.
Two tiny history-making satellites, collectively named MarCo, joined InSight on its journey to Mars. These briefcase-sized CubeSats’ initial job of demonstrating their relay capabilities during the craft’s landing event successfully sent data back to scientists on Earth much quicker than they would have received without them (near real-time, actually). Due to transmission delays and the locations of other satellites already orbiting the planet, InSight’s short journey to the surface may have taken hours for scientists on Earth to confirm otherwise. One of the MarCo satellites even sent back a photo of Mars as it flew by the planet, the low-cost mission itself representing a hopeful outlook on the future of deep space exploration. NASA has not made contact with the two tiny travellers since January 4, 2019, however, and both craft are now located over a million miles past Mars in Sun-centric orbits.
Now that InSight’s seismometer is on the surface and protected, it will proceed to deploy its heat flow probe next week. Essentially, this means the craft will drill almost 16 feet into the Martian surface and measure the heat of the planet’s interior. The goal of this research is to determine whether Mars is made of the same stuff as the Earth and the Moon, potentially answering questions about all of the planetary bodies’ evolution. Stay tuned!
Tesla has quietly rolled out one of its most practical software updates yet — and it could add real dollars to every used Model 3, Y, S, and X on the road.
Starting with the latest Tesla app version, owners now receive an official “Certification of Repaired HV Battery” whenever Tesla performs a major high-voltage battery repair or full replacement. The digital certificate appears directly in the vehicle’s Service History tab inside the Tesla app.
It’s permanent, verifiable, and downloadable as a PDF, so sellers can hand it over to buyers in seconds.
For years, the used EV market has suffered from one glaring problem: nobody could prove what happened to the battery.
Service invoices often vanish when a car changes hands. Third-party battery-health scans are expensive and inconsistent. Buyers, staring at a car with 80,000 miles and an 8-year warranty ticking down, would negotiate hard — or walk away entirely — because the battery is the single most expensive part of any Tesla.
That uncertainty routinely shaved thousands off resale values and slowed the entire secondhand market.
Now Tesla has eliminated the guesswork. The new certificate, which was spotted by Tesla App Updates, logs exactly what work was done, when, and by whom. It lives inside the car’s digital profile forever, exactly where any future owner will look. No more digging through old emails or hoping the previous owner kept paperwork.

The outlet describes why the update is so important:
-
Official Digital Certificates: The string “Certification of Repaired HV Battery” confirms that if your vehicle undergoes a major battery repair or replacement, Tesla will now issue an official, verifiable digital certificate documenting the work.
-
Service History Integration: Strings such as viewRepairedBatteryCert and repairedBatteryCertId indicate that this document won’t be lost in an old email thread. It will be permanently anchored to your vehicle’s profile inside the app’s Service History tab.
-
Easy Exporting: The service_history_repaired_battery_cert_download_fail error state indicates you will be able to download this certificate directly to your phone as a file (likely a PDF) to share with others.
Sellers who have already replaced packs under warranty are especially excited; they can now prove the vehicle received a fresh Tesla battery without any gray-area questions.
The timing couldn’t be better. As more Teslas roll off 8-year/100,000- or 120,000-mile battery warranties, the used market is exploding. Lenders, insurers, and even auction houses have quietly asked for better battery documentation for years. Tesla’s certificate hands it to them on a silver platter.
For current owners, the feature adds peace of mind and protects long-term value. For buyers, it removes the single biggest risk in any used EV purchase. And for Tesla itself, it quietly strengthens the entire ownership ecosystem — making vehicles more liquid, more desirable, and more valuable over time.
In an industry obsessed with range numbers and 0-60 times, Tesla just proved that sometimes the biggest innovation is a simple line in the Service History tab. One small certificate, one giant step for used-EV confidence.
In the global race toward electrification, Norway stands unchallenged as the world’s most mature EV market.
In the first quarter of this year, EVs captured a staggering 97.9 percent market share, with plugin EVs reaching 98.6 percent. Out of 27,175 new vehicles registered, non-BEV powertrains have been reduced to statistical noise—petrol and hybrids combined accounted for fewer than 80 units.
At the heart of this transformation is Tesla.
The Model Y dominated overall vehicle sales with 5,406 units, outselling the next five best-selling non-Tesla models combined. The refreshed Model 3 followed in second place with 2,010 units, giving Tesla a commanding one-two finish. Toyota’s bZ4X placed third with 1,400 units, while Volvo’s EX40 and others trailed further back.
The @Tesla Model Y was the #1 best-selling vehicle overall in Norway in Q1 2026 by a wide margin, with BEVs in general taking a 97.9% market share. Model 3 ranked #2.

This dominance is no fluke. Norway has spent decades building the infrastructure and policy framework that makes EVs the rational choice. Generous tax incentives, exemption from VAT, reduced tolls, free ferries for EVs, and a dense charging network have turned the country into a living laboratory for mass adoption. High fuel prices—often exceeding $8 per gallon—further tilt the economics decisively toward electricity.
The result is a market where choosing anything but an EV feels increasingly anachronistic. Diesel and petrol cars have all but vanished from new registrations. Even plug-in hybrids, once a transitional favorite, have collapsed to 0.7 percent share.
Chinese brands like XPeng, BYD, and Zeekr are making inroads, while legacy European and Japanese automakers scramble to field competitive BEVs. Yet Tesla’s combination of range, performance, software, Supercharger network, and brand cachet continues to set the benchmark.
Norway’s Q1 figures come after a volatile start to 2026 caused by VAT changes that pulled forward sales into late 2025. The market rebounded strongly in March, underscoring underlying demand. Tesla’s Q1 performance in the country also jumped significantly year-over-year, reinforcing its position even as competition intensifies.
What happens in Norway rarely stays there. The country has long served as a bellwether for EV trends across Europe and beyond.
Its near-total transition demonstrates that when incentives align with infrastructure and consumer economics, adoption accelerates dramatically. For automakers, Norway signals a future where success hinges not on legacy powertrains but on delivering compelling electric vehicles at scale.
As other nations ramp up their own EV ambitions, Tesla’s continued reign in the world’s heaviest EV market sends a clear message: in a fully mature electric future, the company that started the revolution remains the one to beat. With the Model Y still the best-selling vehicle overall—quarter after quarter—Norway’s roads are a rolling testament to Tesla’s enduring leadership.
Tesla has taken home the “Overall Loyalty to Make” award from S&P Global Mobility for the fourth consecutive year, reinforcing Tesla owners’ willingness to come back. The 2025 awards are based on S&P Global Mobility’s analysis of 13.6 million new retail vehicle registrations in the U.S. from October 2024 through September 2025. The complete list of 2025 winners includes General Motors for Overall Loyalty to Manufacturer, Tesla for Overall Loyalty to Make, Chevrolet Equinox for Overall Loyalty to Model, Mini for Most Improved Make Loyalty, Subaru for Overall Loyalty to Dealer, and Tesla again for both Ethnic Market Loyalty to Make and Highest Conquest Percentage.
Tesla’s streak in this category started in 2022, and the brand has now won the Highest Conquest Percentage award for six straight years, meaning it keeps pulling buyers away from other brands at a rate no competitor has matched. Tesla’s retention among Asian households reached 63.6% and among Hispanic households 61.9%, rates that significantly outpace national averages for those groups. That breadth of appeal across demographics adds a layer of significance to a win that some might dismiss as routine.
The timing matters too. After several consecutive quarters of decline, Tesla’s share of U.S. EV sales jumped to 59% in Q4 2025. That rebound, arriving just as competitors were flooding the market with new models and incentives, suggests Tesla’s loyalty numbers are not simply the result of limited alternatives. Buyers are still choosing it when they have plenty of other options.
What keeps Tesla owners coming back has a lot to do with the and convenience of charging. The Supercharger network is the most straightforward example. With over 65,000 Superchargers globally, it remains the largest and most reliable fast-charging network in the world, and owners who have built their routines around it face a real practical cost when considering a switch. Competitors have made progress, but the consistency, speed, and availability of Tesla’s network is still the benchmark the rest of the industry is chasing. Then there is the software side. Tesla has built a model where the car you own today is functionally different from the car you bought two years ago, through over-the-air updates that add continuous game-changing improvements such as Full Self-Driving that has moved from a driver-assist feature to an increasingly capable autonomous system. For many Tesla owners, leaving the brand means starting over with a car that will not get meaningfully better over time, and that is a trade-off fewer and fewer are willing to make.
