NASA spacecraft successfully slams into asteroid ten months after SpaceX launch
Ten months after launching into interplanetary space on a SpaceX Falcon 9 rocket, NASA’s Double Asteroid Redirect Test (DART) spacecraft has successfully impacted an asteroid moon.
Falcon 9 lifted off from Vandenberg Space Force Base (VSFB) Space Launch Complex 4 (SLC-4) carrying the 630-kilogram (~1400 lb) spacecraft on November 24th, 2021. The rocket performed flawlessly, continuing a streak of successful launches, and boosted DART on its way to a near-Earth asteroid pair.
The goal: slam into the small asteroid moon Dimorphos at an eyewatering speed of 6.3 kilometers per second (14,000 mph / Mach 18). Ten months later, the spacecraft has accomplished exactly that, successfully crashing into a target about 160 meters (530 ft) wide just 17 meters away from a perfect ‘bullseye’ after traveling for ten months and hundreds of millions of kilometers through space. Depending on the results NASA and dozens of other groups will now attempt to glean from ground and space telescopes, the successful impact could be a major leap forward for the field of planetary defense.
The main goal of planetary defense is to protect humanity’s home planet from asteroids, a threat that has routinely caused mass-extinction events throughout the multibillion-year history of life on Earth. With the technology to both detect and reach virtually all near-Earth objects (NEOs) more or less at hand, DART is the first attempt to test and verify what would seem to be the easiest and most obvious method of redirecting asteroids: knocking them off course with the spacecraft itself.
Planetary science and the behavior of things in microgravity conditions have a tendency to defy expectations, however, so testing that assumption is essential. The perfect way to do so came to DART Lead Investigator Andy Chang in a burst of mid-exercise inspiration: instead of hitting any odd NEO, a small spacecraft could slam into a tiny asteroid moon of a much larger parent asteroid. Hitting an asteroid moon would mitigate the small but nonzero risk of accidentally redirecting the target towards Earth while also amplifying the results, making them much easier to observe from tens of millions of kilometers away.
Rather than being forced to search for a virtually imperceptible change in a single asteroid’s half-billion-kilometer-long orbit, the results of hitting the right asteroid moon would be much more easily detectable as a change in the moon’s much smaller orbit around its untouched parent asteroid.
The problem is that aside from spectrographic readings that tell scientists the broad strokes of an asteroid’s composition and other telescope images that can make out the rough shape, it’s very difficult to scout the objects without actually visiting them. And given the difficulty, spacecraft have only visited a handful of the virtually countless asteroids of our solar system. Without knowing exactly what a target asteroid’s surface and subsurface are like, it’s hard to predict exactly what a spacecraft impacting that asteroid will do. A looser surface, which is what most visited asteroids appear to have, would be much worse at momentum transfer than a boulder or relatively solid surface of rock.
As an example, as DART rapidly approached and revealed more detailed views of the surface of Didymos and Dimorphos in its final minutes, Chang himself was surprised to see just how rough and boulder-strewn the surface of both asteroids were. Then, after the spacecraft impact, many scientists were also surprised to almost immediately see a massive cloud of dust – easily visible from ground-based telescopes – ejected from Dimorphos.
Despite the DART spacecraft’s eventful demise, the fun has only just begun on the ground as scientists attempt to solve that riddle (and many others) and begin searching for changes in Dimorphos’ orbit. Data will soon arrive from even larger and more prestigious observatories, including NASA’s space-based Hubble and Webb Space Telescopes. Italian companion cubesat LICIACube, which deployed from DART shortly before impact, will also downlink images it took up close, potentially offering the most detailed view of the impact for years.
Meanwhile, the European Space Agency (ESA) is developing a spacecraft called Hera that will launch in 2024 and attempt to enter orbit around Didymos and Dimorphos as early as late 2026 to examine the aftermath of DART’s last stand in even greater detail.
In the more distant future, particularly if the international science community ultimately concludes that DART did successfully redirect an asteroid (moon), it’s possible that the mission will help to kickstart an entirely new global project and fleet of spacecraft that will stand ready to protect Earth if the need ever truly arises. With a little luck and a modest amount of government funding, humanity may soon be able to entirely eradicate one of the most infamous sources of mass extinction.

Tesla Full Self-Driving pricing strategy eliminates one recurring complaint
Tesla’s new Full Self-Driving pricing strategy will eliminate one recurring complaint that many owners have had in the past: FSD transfers.
In the past, if a Tesla owner purchased the Full Self-Driving suite outright, the company did not allow them to transfer the purchase to a new vehicle, essentially requiring them to buy it all over again, which could obviously get pretty pricey.
This was until Q3 2023, when Tesla allowed a one-time amnesty to transfer Full Self-Driving to a new vehicle, and then again last year.
Tesla is now allowing it to happen again ahead of the February 14th deadline.
The program has given people the opportunity to upgrade to new vehicles with newer Hardware and AI versions, especially those with Hardware 3 who wish to transfer to AI4, without feeling the drastic cost impact of having to buy the $8,000 suite outright on several occasions.
Now, that issue will never be presented again.
Last night, Tesla CEO Elon Musk announced on X that the Full Self-Driving suite would only be available in a subscription platform, which is the other purchase option it currently offers for FSD use, priced at just $99 per month.
Tesla is shifting FSD to a subscription-only model, confirms Elon Musk
Having it available in a subscription-only platform boasts several advantages, including the potential for a tiered system that would potentially offer less expensive options, a pay-per-mile platform, and even coupling the program with other benefits, like Supercharging and vehicle protection programs.
While none of that is confirmed and is purely speculative, the one thing that does appear to be a major advantage is that this will completely eliminate any questions about transferring the Full Self-Driving suite to a new vehicle. This has been a particular point of contention for owners, and it is now completely eliminated, as everyone, apart from those who have purchased the suite on their current vehicle.
Now, everyone will pay month-to-month, and it could make things much easier for those who want to try the suite, justifying it from a financial perspective.
The important thing to note is that Tesla would benefit from a higher take rate, as more drivers using it would result in more data, which would help the company reach its recently-revealed 10 billion-mile threshold to reach an Unsupervised level. It does not cost Tesla anything to run FSD, only to develop it. If it could slice the price significantly, more people would buy it, and more data would be made available.

Tesla Model 3 and Model Y dominates U.S. EV market in 2025
The figures were detailed in Kelley Blue Book’s Q4 2025 U.S. Electric Vehicle Sales Report.
Tesla’s Model 3 and Model Y continued to overwhelmingly dominate the United States’ electric vehicle market in 2025. New sales data showed that Tesla’s two mass market cars maintained a commanding segment share, with the Model 3 posting year-to-date growth and the Model Y remaining resilient despite factory shutdowns tied to its refresh.
The figures were detailed in Kelley Blue Book’s Q4 2025 U.S. Electric Vehicle Sales Report.
Model 3 and Model Y are still dominant
According to the report, Tesla delivered an estimated 192,440 Model 3 sedans in the United States in 2025, representing a 1.3% year-to-date increase compared to 2024. The Model 3 alone accounted for 15.9% of all U.S. EV sales, making it one of the highest-volume electric vehicles in the country.
The Model Y was even more dominant. U.S. deliveries of the all-electric crossover reached 357,528 units in 2025, a 4.0% year-to-date decline from the prior year. It should be noted, however, that the drop came during a year that included production shutdowns at Tesla’s Fremont Factory and Gigafactory Texas as the company transitioned to the new Model Y. Even with those disruptions, the Model Y captured an overwhelming 39.5% share of the market, far surpassing any single competitor.
Combined, the Model 3 and Model Y represented more than half of all EVs sold in the United States during 2025, highlighting Tesla’s iron grip on the country’s mass-market EV segment.
Tesla’s challenges in 2025
Tesla’s sustained performance came amid a year of elevated public and political controversy surrounding Elon Musk, whose political activities in the first half of the year ended up fueling a narrative that the CEO’s actions are damaging the automaker’s consumer appeal. However, U.S. sales data suggest that demand for Tesla’s core vehicles has remained remarkably resilient.
Based on Kelley Blue Book’s Q4 2025 U.S. Electric Vehicle Sales Report, Tesla’s most expensive offerings such as the Tesla Cybertruck, Model S, and Model X, all saw steep declines in 2025. This suggests that mainstream EV buyers might have had a price issue with Tesla’s more expensive offerings, not an Elon Musk issue.
Ultimately, despite broader EV market softness, with total U.S. EV sales slipping about 2% year-to-date, Tesla still accounted for 58.9% of all EV deliveries in 2025, according to the report. This means that out of every ten EVs sold in the United States in 2025, more than half of them were Teslas.

Tesla Model 3 and Model Y earn Euro NCAP Best in Class safety awards
“The company’s best-selling Model Y proved the gold standard for small SUVs,” Euro NCAP noted.
Tesla won dual categories in the Euro NCAP Best in Class awards, with the Model 3 being named the safest Large Family Car and the Model Y being recognized as the safest Small SUV.
The feat was highlighted by Tesla Europe & Middle East in a post on its official account on social media platform X.
Model 3 and Model Y lead their respective segments
As per a press release from the Euro NCAP, the organization’s Best in Class designation is based on a weighted assessment of four key areas: Adult Occupant, Child Occupant, Vulnerable Road User, and Safety Assist. Only vehicles that achieved a 5-star Euro NCAP rating and were evaluated with standard safety equipment are eligible for the award.
Euro NCAP noted that the updated Tesla Model 3 performed particularly well in Child Occupant protection, while its Safety Assist score reflected Tesla’s ongoing improvements to driver-assistance systems. The Model Y similarly stood out in Child Occupant protection and Safety Assist, reinforcing Tesla’s dual-category win.
“The company’s best-selling Model Y proved the gold standard for small SUVs,” Euro NCAP noted.
Euro NCAP leadership shares insights
Euro NCAP Secretary General Dr. Michiel van Ratingen said the organization’s Best in Class awards are designed to help consumers identify the safest vehicles over the past year.
Van Ratingen noted that 2025 was Euro NCAP’s busiest year to date, with more vehicles tested than ever before, amid a growing variety of electric cars and increasingly sophisticated safety systems. While the Mercedes-Benz CLA ultimately earned the title of Best Performer of 2025, he emphasized that Tesla finished only fractionally behind in the overall rankings.
“It was a close-run competition,” van Ratingen said. “Tesla was only fractionally behind, and new entrants like firefly and Leapmotor show how global competition continues to grow, which can only be a good thing for consumers who value safety as much as style, practicality, driving performance, and running costs from their next car.”
