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 launched the Model Y Standard as an attempt to offer affordable electric vehicles to consumers now that the $7,500 EV tax credit is gone. We were able to spend four days with the car, and it was more than enough time to determine whether or not the car was worth the $9,000 discount compared to the Premium All-Wheel-Drive configuration, which is what I drive daily.
The Model Y Standard was stripped of some of the features that are present in the Premium trims of the Model Y: no glass roof, a sound system with roughly half the speakers, fewer acoustic-lined glass windows, less storage, and less functionality from an interior standpoint.
However, there are some real advantages to purchasing a Standard Model Y, and there are a handful of situations where this car would be well-suited.
Do I think it is worth the lower price? Well, I’ll get to that later in this article.
Initial Thoughts
In my first impressions review of the Model Y Standard, I talked about the face-value differences between my Model Y Premium and the new, more affordable trim. You will first notice the lack of storage between the front two seats, as the cupholder and additional storage bin sliding doors are void. You still get the cupholders, but they are exposed, which isn’t a huge deal, but it definitely takes away from the sleek look the Premium trim offers.
Additionally, the textile seats replace those of the vegan leather that is available in the upper-level trims. I mentioned previously that I could take or leave the vegan leather for the textile seats, as they are easy to clean, quick drying, and hide oils from your skin much better than leather does.
However, there comes one big sacrifice that I have been spoiled by, as the textile seats are not ventilated, so say goodbye to cooling your keister in the Summertime.
The lack of a glass roof is something many owners might not even notice. However, I have been spoiled by the glass roof in my car, and I look out of it every time I’m in my car. It is one of my favorite features, without a doubt. While it would not be a dealbreaker for me, it would be something I would miss terribly.
Things I Noticed After Several Days
Cabin Noise
One of the biggest things I noticed after the first two days in the Model Y Standard is that the cabin is much louder than the Premium. This is because Tesla did not acoustically line all of the glass in the Standard configuration, as it did in the Premium. The side windows are not treated, just the windshields. Therefore, you notice the noise level in the cabin is louder than in the Premium.
If you had not been driving in a Premium trim for a few months, you might not notice it. However, it is something that is a big sacrifice when moving to a different trim level, especially one that is less premium than what you might currently drive.
I have always been so shocked at how amazingly quiet the Premium trim’s cabin is; my Model Y is extremely peaceful, even when I’m sitting in bumper-to-bumper traffic, and people have modified mufflers and exhaust systems, tractor-trailers are going by, or crotchrockets are zipping by on the interstate.
This is a huge difference between the two cars, and it is something that is really hard to get used to. I know, first-world problems, right? But when you’re paying between $39,990 and $48,990 for a car, those little things truly do matter.
Stereo System Differences
Another thing I was very aware of was how weak the sound system is. I think if I had bought a Standard Model Y, I would have looked at having the speakers and subwoofers upgraded; I was almost disappointed in how much of a change it was between the two cars.
When I finally picked up my Model Y Premium on Friday (which had been detailed by the awesome team at Tesla Mechanicsburg), the first thing I did was crank up the volume and listen to some music. I really missed having a premium sound system.
Ride Quality
There are virtually no differences between the two cars in terms of ride quality. They are both extremely fun to drive, and the suspension in the Model Y Standard feels perhaps a little bit stiffer than the Premium. Regardless, I didn’t truly notice all that much of a change.
Driving this car around windy roads and tight turns was just as fun as my Model Y Premium. It was a blast to test out, and the slight change in feel was welcome. It’s always fun to drive new cars.
Performance
This is the first EV I’ve ever ridden in where I did not feel that awesome sensation of instant torque. It’s still a quick car, but it is missing that pep in its step that many of us have become accustomed to.
If you want to get someone’s true reaction to EV acceleration, let me just put it this way: This is not the car to do it in.
Some Little-Known Facts About the Model Y Standard
Most of us know that the Model Y Standard has a glass roof, but it is opaque, so even if you took out the headliner, you still would not see out of it. However, there is an interesting little tidbit from a Service perspective that does not make much sense.
If the Model Y glass roof cracks or is broken and needs to be replaced, Service is required to pull off the entire headliner and topside interior to access the glass. It cannot be replaced from the outside. In the Premium, because the glass is exposed, it is a much simpler process to replace the glass. This was an interesting thing I learned.
Additionally, the seat controls are only available on the center screen, which makes it difficult to adjust the seat if you are larger than the person who sat in the car previously. In order to adjust the seat, you’ll have to lean over the chair, access the controls from the screen, and adjust it manually before getting in.
Is the Tesla Model Y Standard Worth the Cheaper Price?
For an additional $9,000 to buy the Model Y Premium AWD, you would get a more capable powertrain, a quieter cabin, better performance, an upgraded interior, more storage, a better sound system, and more luxury features.
To me, the Standard is a car that seems extremely ideal for a teenager’s first vehicle (I got a $1,500 1998 VW Jetta K2 with 200,000 miles when I was 16), or a fleet vehicle. This would be the perfect car for salespeople to use: it does not have all the bells and whistles, it is efficient, and it is just what is needed to drive around to meetings.
For a personal car, it really depends on what you think you need. Admittedly, I’ve been spoiled by the Premium configuration, and personally, I wouldn’t go down to the Standard after owning a Premium trim.

Tesla’s new Holiday perk is timed perfectly to make FSD a household name
Tesla AI4 owners get FSD (Supervised) through Christmas, New Year’s Eve and well into the post-holiday travel season.
Tesla quietly rolled out a free Full Self-Driving (Supervised) trial for roughly 1.5 million HW4 owners in North America who never bought the package, and the timing could very well be genius.
As it turns out, the trial doesn’t end after 30 days. Instead, it expires January 8, 2026, meaning owners get FSD (Supervised) through Christmas, New Year’s Eve and well into the post-holiday travel season. This extended window positions the feature for maximum word-of-mouth exposure.
A clever holiday gift
Tesla watcher Sawyer Merritt first spotted the detail after multiple owners shared screenshots showing the trial expiring on January 8. He confirmed with affected users that none had active FSD subscriptions before the rollout. He also observed that Tesla never called the promotion a “30-day trial,” as the in-car message simply reads “You’re Getting FSD (Supervised) For the Holidays,” which technically runs until after the new year.
The roughly 40-day period covers peak family travel and gatherings, giving owners ample opportunity to showcase the latest FSD V14’s capabilities on highway trips, crowded parking lots and neighborhood drives. With relatives riding along, hands-off highway driving and automatic lane changes could become instant conversation starters.
Rave reviews for FSD V14 highlight demo potential
FSD has been receiving positive reviews from users as of late. Following the release of FSD v14.2.1, numerous owners praised the update for its smoothness and reliability. Tesla owner @LactoseLunatic called it a “huge leap forward from version 14.1.4,” praising extreme smoothness, snappy lane changes and assertive yet safe behavior that allows relaxed monitoring.
-->Another Tesla owner, @DevinOlsenn, drove 600 km without disengagements, noting his wife now defaults to FSD for daily use due to its refined feel. Sawyer Merritt also tested FSD V14.2.1 in snow on unplowed New Hampshire roads, and the system stayed extra cautious without hesitation. Longtime FSD tester Chuck Cook highlighted improved sign recognition in school zones, showing better dynamic awareness. These reports of fewer interventions and a more “sentient” drive could turn family passengers into advocates, fueling subscriptions come January.

Elon Musk predicts AI and robotics could make work “optional” within 20 years
Speaking on entrepreneur Nikhil Kamath’s podcast, Musk predicted that machines will soon handle most forms of labor, leaving humans to work only if they choose to.
Elon Musk stated that rapid advances in artificial intelligence and robotics could make traditional work unnecessary within two decades.
Speaking on entrepreneur Nikhil Kamath’s podcast, Musk predicted that machines will soon handle most forms of labor, leaving humans to work only if they choose to.
Work as a “hobby”
During the discussion, Musk said the accelerating capability of AI systems and general-purpose robots will eventually cover all essential tasks, making human labor a choice rather than an economic requirement. “In less than 20 years, working will be optional. Working at all will be optional. Like a hobby,” Musk said.
When Kamath asked whether this future is driven by massive productivity growth, Musk agreed, noting that people will still be free to work if they enjoy the routine or the challenge. He compared future employment to home gardening, as it is something people can still do for personal satisfaction even if buying food from a store is far easier.
“Optional” work in the future
Elon Musk acknowledged the boldness of his claim and joked that people might look back in 20 years and say he was wrong. That being said, the CEO noted that such a scenario could even happen sooner than his prediction, at least if one were to consider the pace of the advancements in AI and robotics.
-->“Obviously people can play this back in 20 years and say, ‘Look, Elon made this ridiculous prediction and it’s not true,’ but I think it will turn out to be true, that in less than 20 years, maybe even as little as ten or 15 years, the advancements in AI and robotics will bring us to the point where working is optional,” Musk said.
Elon Musk’s comments echo his previous sentiments at Tesla’s 2025 Annual Shareholder Meeting, where he noted that Optimus could ultimately eliminate poverty. He also noted that robots like Optimus could eventually provide people worldwide with the best medical care.
