NASA aces most challenging Mars rover landing to date
After a nearly 300 million mile (480 million kilometer), seven-month-long journey, the world watched as NASA’s Mars 2020 Perseverance mission successfully completed the most challenging and precise landing the agency has ever attempted on Thursday (Feb. 18). Perseverance is NASA’s fifth rover and overall ninth mission to successfully land on the Red Planet.
On Thursday afternoon, the alien invader punched through the relatively thin Martian atmosphere streaking across the sky at a blazing 12,100 mph (19,500 kph). Then it shed a few layers, deployed the largest-ever supersonic parachute, and slowed down just enough to use a rocket-propelled crane to drop an autonomous, nuclear-powered, robotic astrobiologist called Perseverance on the surface of Mars.
Flawlessly completing the entry, descent, and landing sequence of its mission to land in Mars’ hostile Jezero Crater, NASA’s Mars 2020 Perseverance mission officially marked the completion of its interplanetary travel phase and began its mission to collect evidence of ancient, microbial Martian life.
Getting to Mars

On July 30, 2020, NASA’s Mars 2020 Perseverance mission launched aboard a United Launch Alliance Atlas V 541 rocket from Space Launch Complex 41 at Cape Canaveral Space Force Base. Aboard that rocket was NASA’s most ambitious Mars mission to date. The launch phase of the mission suffered a few minor delays ultimately shifting the launch date from July 18, 2020 to July 30, 2020. However, ULA’s Atlas V first stage rocket and Centaur upper stage delivered NASA’s Mars 2020 Perseverance mission into such an accurate trajectory that the 2,260 lb (1,025 kg) rover landed on its specified February 18 landing date despite the delays in the launch timeline.
In total, three missions to Mars – China’s Tianwen-1, the United Arab Emirates Hope Probe, and NASA’s Perseverance – left Earth in the summer of 2020. All three missions targeted to leave Earth prior to August to best take advantage of the minimal distance between the planets during what is called opposition. The opposition between Earth and Mars only occurs once every 22 months. If the Perseverance mission had missed its launch date it would’ve had to wait until 2022 for a chance to travel to the Red Planet.
Entry, Descent, and Landing – a controlled disassembly
As Perseverance descended into the Martian atmosphere the Cruise Phase – hardware that propelled the spacecraft through space for seven months – was jettisoned. The Perseverance rover safely tucked inside the aeroshell and protected by a robust heat shield soared through the thin Martian atmosphere enduring an extreme amount of friction that produced heat energy that reached up to 2,370 degrees Fahrenheit (about 1,300 degrees Celsius).
Once through the period of peak heating the heat shield was jettisoned exposing Perseverance to the Martian environment for the first time. Then about 7 miles (11 kilometers) from the surface the largest supersonic parachute NASA has ever sent to another planet – 70.5 feet (21.5 meters) in diameter – was deployed drastically slowing the spacecraft.
While still descending, the controlled descent module – called the sky crane – separated from the backshell about 1.3 miles (2.1 kilometers) above the surface to free-fly in the Martian atmosphere. The descent module used a new landing technology called Terrain-Relative Navigation used a constant stream of visual input and guidance collected from the Vision Compute Element and Rover Compute Element to determine the safest reachable landing site.
The throttleable rockets on the powered descent module steered the rover to its landing spot in Mars’ Jezero Crater and slowed to approximately 1.7 mph (2.7 kph) about 66 feet (20 meters) above the Martian surface. Perseverance was then lowered using a system of Nylon cords which were autonomously severed upon touchdown. The final stage of the controlled disassembly was for the sky crane to throttle its rockets back up and fly away for a crash landing a safe distance from the rover.
Ultimately, the Perseverance rover landed about a kilometer south of the intended delta of the Jezero Crater.

Perseverance made it to Mars, now what?
Getting to Mars was only the first of many milestones that Perseverance is expected to achieve during its projected one Mars year-long mission – about 687 Earth days. Now that the rover has touched down the science will begin.
First and foremost once Perseverance stretched its legs, so to speak, the first event took place just minutes after landing. Perseverance captured photos of the Martian surface with a pair of engineering cameras called Hazard Cameras mounted to the front and back of the rover.
The upgraded Navigation and Hazard cameras feature the capability to capture imagery of the Martian surface in 20 megapixel high-definition resolution for the first time. In the coming days, more images will be relayed back to Earth taken with the rover’s Navigation cameras and Mastcam-Z.
Once on Mars, the control of the Perseverance rover was transitioned from NASA JPL’s EDL team to the Perseverance Surface team. The Surface Phase of the Mars 2020 mission – or the phase of the mission that consists of the four main science objectives – began about twenty minutes after the touchdown.
Perseverance was sent to Mars to determine whether life ever existed on Mars, characterize the climate, characterize the geology, and prepare for the eventual human exploration of Mars. To achieve these massive science goals, the robotic astrobiologist was sent with an impressive suite of scientific research tools. Over the next 30 Martian days – called sols – the rover will begin to unfurl and begin testing the various pieces of hardware in preparation for exploring the delta of Jezero Crater.
Deploying the stowaway
Perseverance not only took a roving science lab to Mars, but it also took the first rotorcraft helicopter to be deployed to another planet dubbed Ingenuity. Ingenuity is a small double-bladed rotorcraft weighing only about 4 pounds (1.8 kilograms).
After the initial 30 Ssls of stretching its legs, Perseverance will travel a short distance to find a flat area of the Martian surface to deploy the Ingenuity helicopter. Once deployed, the Ingenuity team will have a technology demonstration window of approximately 30 sols to complete the first flight test of Ingenuity – the first time powered, controlled flight will be attempted on another planet.
Landing is just the beginning
As exciting as landing on Mars was, it is only the beginning for the Mars 2020 Perseverance rover. The nuclear-powered astrobiology robot will spend the next Martian year excavating the surface of a very rich delta in the Jezero crater searching for the first evidence of ancient, microbial life.
Even more exciting is that Perseverance is only the first phase of a larger mission called the Mars Sample Return mission that will someday bring the excavated samples that Perseverance collects back to Earth in a joint effort between NASA and the European Space Agency.
Although the Perseverance mission is only intended to last one Martian year, Perseverance has the capacity to extend its mission to nearly 15 years thanks to its power source, a Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) which produces a steady stream of electricity provided by the radioactive decay of plutonium-238. Perseverance could potentially outlast all of NASA’s other Mars missions.

Tesla Semi gets new product launch as mass manufacturing hits Plaid Mode
While the 1.2 MW Megacharger handles quick 30-minute en-route boosts, the Basecharger serves as a reliable overnight solution for longer dwell times at warehouses, distribution centers, fleet yards, and even, potentially, homes.
The Tesla Semi is getting a new production launch as mass manufacturing on the all-electric truck is gearing up to hit Plaid Mode.
Tesla has introduced a game-changing addition to its commercial charging lineup with the new 125 kW Basecharger for Semi. Launched this week as part of the new “Semi Charging for Business” program, this compact unit is purpose-built for depot and overnight charging of Tesla Semi trucks.
While the 1.2 MW Megacharger handles quick 30-minute en-route boosts, the Basecharger serves as a reliable overnight solution for longer dwell times at warehouses, distribution centers, fleet yards, and even, potentially, homes.
Our new 125 kW Basecharger is designed for longer dwell times and overnight charging of Semis. It’s the “home charging” for heavy-duty fleets.
It features a fully integrated design that eliminates the need for a separate AC-to-DC cabinet, simplifying installation. The 6 meter… https://t.co/ovy1C4PsRW pic.twitter.com/vBUCNMzs57

Delivering up to 60 percent of the Semi’s range in roughly four hours, perfect for overnight top-ups during mandated driver rest periods or while trucks are loaded or unloaded. Its fully integrated design eliminates the need for bulky separate AC-to-DC cabinets.
Tesla engineers tucked one of the power modules from a V4 Supercharger Cabinet directly inside the sleek post, resulting in a compact footprint. It also features a six-meter cable for layout flexibility. This is one thing that must have been learned through the V4 Supercharger rollout.
Installation and operating costs drop dramatically thanks to daisy-chaining. Up to three Basechargers can share a single 125 kVA breaker, slashing electrical infrastructure requirements. The unit outputs 150 amps continuous across an 180–1,000 VDC range, matching the Semi’s high-voltage architecture while supporting the MCS 3.2 standard.
Tesla Semi sends clear message to Diesel rivals with latest move
Priced from $40,000 for a minimum order of two units, the Basecharger is far more affordable than the $188,000 Megacharger setup for two posts. Deliveries begin in early 2027. Buyers also receive Tesla’s full network-level software, remote monitoring, maintenance, and a guaranteed 97 percent or higher uptime—critical for fleet reliability.
This launch arrives as Tesla accelerates high-volume Semi production at its Nevada factory, targeting 50,000 units annually. By pairing affordable depot charging with ultra-fast highway options, Tesla removes one of the biggest obstacles to electrifying Class 8 trucking: infrastructure cost and complexity.
Fleet operators stand to gain lower electricity rates during off-peak hours, dramatically reduced maintenance compared to diesel, and quieter yards at night. The Basecharger isn’t just another charger—it’s the practical bridge that makes large-scale electric semi adoption economically viable.
With the Basecharger handling “home” duties and Megachargers powering the road, Tesla is delivering a complete ecosystem that could finally tip the scales toward zero-emission freight. For trucking companies ready to go electric, the future just got a whole lot more charger-friendly.

Tesla revises new Intervention Reporting system with Full Self-Driving
It is the second revision to the program as Tesla is trying to make it easier to decipher driver and owner complaints, but also to make it easier to report issues within the suite for them.
Tesla has revised its new Intervention Reporting system within the Full Self-Driving suite that now categorizes reasons that drivers take over when the semi-autonomous driving functionality is active.
It is the second revision to the program as Tesla is trying to make it easier to decipher driver and owner complaints, but also to make it easier to report issues within the suite for them.
With the initial rollout of Full Self-Driving v14.3.2, Tesla included a new reporting menu that gave four options for an intervention: Preference, Comfort, Critical, and Other. A slightly revised version of Full Self-Driving with the same ID number then came out a few days later, changing the “Other” option to “Navigation” after numerous complaints from owners.
It appears Tesla has listened to those owners once again and has not only made it smaller and more compact, but also easier to report the issues than previously.
The new menu is now embedded within the request for a Voice Memo from Tesla, and does not block the entire screen, as the second rollout of the menu was:
Thank you Tesla! The new intervention screen is much better! @Tesla_AI pic.twitter.com/1lea9G27N1
— Dirty Tesla (@DirtyTesLa) May 1, 2026
There will likely be one additional revision to the Interventions Menu, as we have coined it here at Teslarati.
Unfortunately, at times, there are no reasons for an intervention at all, but the menu does not give an option to simply disregard the reporting and forces the driver to choose one of the options. We, as well as other notable Tesla influencers, indicated that there is not always a reason for an intervention.
For example, I choose to back into my parking spot in my neighborhood at least some of the time for the reason of charging. I usually hit “Preference” for this, but it sends a false positive to Tesla that there was a reason I took over that I was unhappy with.
Tesla begins probing owners on FSD’s navigation errors with small but mighty change
Instead, I’m simply performing a maneuver that is not yet available to us. When Tesla allows drivers to choose the orientation at which their car enters a parking spot, I and many others won’t have to deal with this menu.
Others are still skeptical that it will help resolve any issues whatsoever and prefer to disregard the menu altogether. It does seem as if Tesla will issue another revision in the coming days to allow this to happen.

California hits Tesla Cybercab and Robotaxi driverless cars with new law
California just gave police power to ticket driverless cars, including Tesla’s Cybercab fleet.
California DMV formally adopted new rules on April 29, 2026 that allow law enforcement to issue “notices of noncompliance”, or in other words ticket autonomous vehicle companies when their cars commit moving violations. The rules take effect July 1, 2026 and officially closes a regulatory gap that previously let driverless cars operate on public roads with nearly no traffic enforcement consequences.
Until now, state traffic laws only applied to human “drivers,” which meant that when no person was behind the wheel, police had no mechanism to issue a ticket. Officers were limited to citing driverless vehicles for parking violations only. A well-known example came in September 2025, when a San Bruno officer watched a Waymo robotaxi execute an illegal U-turn and could do nothing but notify the company.
Under the new framework, when an officer observes a violation, the autonomous vehicle company is effectively treated as the driver. Companies must report each incident to the DMV within 72 hours, or 24 hours if a collision is involved. Repeated violations can result in fleet size restrictions, operational suspensions, or full permit revocation. Local officials also gained new authority to geofence driverless vehicles out of active emergency zones within two minutes and require a live emergency response line answered within 30 seconds.
Tesla Cybercab ramps Robotaxi public street testing as vehicle enters mass production queue
California’s new enforcement rules arrive at a pivotal moment for Tesla. The company is ramping Cybercab production at Giga Texas toward hundreds of units per week, targeting at least 2 million units annually at full capacity, while simultaneously pushing to expand its Robotaxi service to dozens of U.S. cities by end of 2026. Unsupervised FSD for consumer vehicles is currently targeted for Q4 2026, and when it arrives, Tesla’s fleet may not have a human to absorb legal accountability, under the July 1 rules.
Tesla has confirmed plans to expand its Robotaxi service to seven new cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas, with the service already running without safety drivers in Austin. Musk has said he expects robotaxis to cover between a quarter and half of the United States by end of year.
