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 adjusts one key detail of Robotaxi operations in Austin

Tesla is adjusting one key detail of Robotaxi operations in Austin: service hours.
Tesla’s Robotaxi platform in Austin has been active since late June and has been running smoothly since then. It has its limits, as Tesla has set hours that Robotaxis can operate, as well as a distinct Service Area, also known as a geofence, which has expanded three times already.
While the geofence is currently approximately 170 square miles in size, Tesla has recently enabled freeway drives, which also necessitated an adjustment to the company’s strategy with its “Safety Monitors.”
Tesla explains why Robotaxis now have safety monitors in the driver’s seat
Traditionally, they sit in the passenger’s seat. During highway driving, they move to the driver’s seat.
These are just a few adjustments that have been made over the past two and a half months. Now, Tesla is adjusting the service hours of Robotaxi operation in Austin, but only slightly.
Tesla will now operate its Robotaxi ride-hailing service from 6 a.m. to 2 a.m., extending the hours by two hours. It previously shut down at midnight.

Tesla has implemented a variety of safeguards to ensure riders and drivers are safe during Robotaxi rides, and they have made it a point to adjust things when they feel confident that it will not cause any issues.
Many people have been critical of Robotaxi, especially because a person sits in the front of the car.
However, an accident or some type of mistake could do more damage to the autonomous travel sector than anything else. This would not just impact Tesla, but any company operating an autonomous ride-hailing service in the country.

Tesla Model Y ownership two weeks in: what I love and what I don’t
With any new car, I don’t really find things I dislike within the first few months; the novelty of a shiny new vehicle usually wears off eventually.

I am officially two weeks into Tesla ownership, having picked up my Model Y Long Range All-Wheel-Drive on Saturday, August 30. I have many things I really love, and I’ll do my best to come up with a few things I don’t, although I find that to be very difficult currently.
With any new car, I don’t really find things I dislike within the first few months; the novelty of a shiny new vehicle usually wears off eventually. In the past, I’ve had a car I only kept for nine months, but I loved it for the first two months. I am sure down the road, some things about the Tesla will bother me, but right now, I don’t have too much to complain about.
As for the things I love, I’ll try to keep it to just five, and as I continue to write about my ownership experience in the coming months, I’ll see if these things change.
A Quick Rundown
In the two weeks I have had my new Model Y, I have driven 783 miles. I have driven it manually, used Full Self-Driving, navigated tight city streets in Baltimore, and driven spiritedly on the winding back roads of Pennsylvania.
I traded my ICE vehicle for a Tesla Model Y: here’s how it went
I have had the opportunity to put it to the test in a variety of ways, and I feel like I have a great idea of this car and how it handles and drives just two weeks in.

What I Love About My Tesla Model Y
I am only going to pick a handful of things, but do not take this list as a complete one. I truly have so many things I love about this car, but I want to mention the ones that are not necessarily “novelties.” I love the A/C seats, but it’s not something I feel deserves a mention here, because it would not likely sway someone to consider the car.
Instead, I want to highlight what I feel are things that truly set the Model Y apart from cars I’ve had in the past.
Tesla Full Self-Driving
Available on all Teslas, Full Self-Driving is something I use every day. It is not only a convenience thing, but it is also truly a fun feature to track improvements, and it’s been fun to show a lot of my friends who are not familiar with its capabilities just how safe and impressive it is.
My Fiancè and I have watched Full Self-Driving make slight changes in performance in the two weeks we’ve been using it. I tracked one instance on a Pennsylvania back road when the car stopped at an “Except Right Turn” Stop Sign. Initially, the car stopped, holding up traffic behind it. Just days later, FSD proceeded through that same Stop Sign cautiously, but without coming to a complete stop, which is the proper way to navigate through it.
I took the same route home last night as I did when I took this drive last week. FSD has *already* improved.

This quick adjustment was very impressive, and it even caught the attention of my better half. I will say it has been very fun to watch her fall in love with this car after being very reluctant to watch me get rid of our Bronco Sport.
The Handling
Tesla refined the suspension with the new Model Y, and you can surely feel it. Coming from a larger SUV, I did miss being able to really push the limits of my car on a beautiful, sunny, and warm day, and the winding roads of Pennsylvania are calling me for a drive.
The way this car hugs turns and genuinely puts a smile on my face when I’m pushing it. Dare I say I like driving it more than I like it driving me?
Interior Storage
One of my biggest complaints about my Bronco Sport was that, despite being an SUV, it felt smaller than it was supposed to be. I had trouble fitting golf bags and luggage in the back without having other storage options. It led me to install a roof rack and get a cargo container. I would have to put longer clubs in the back seat so the bags could lie without clubs getting bent.
I don’t seem to have a significant problem with this in the Model Y. Plus, the frunk and the additional cargo under the floor of the trunk are great for bags and other things. It offers 10 cubic feet more of space with the seats down than the Bronco Sport does.
The Entertainment
Not only is the sound system in this car absolutely unbelievable, but I also really enjoy the Tesla Theater, which is really something that has revolutionized how we spend our time in the car.
Charging at the Superchargers has become a new way for us to spend time together. Even if it’s just 30 minutes, my Fiancé’s busy work schedule at the hospital means we don’t get to spend as much time together as we would like. The charging lets us go grab a snack, watch a movie or show in the car, and just be with each other.
It’s honestly my favorite thing about the car so far, that we’ve both truly enjoyed what it has done for us. It put a smile on my face to hear her say, “It’s just so much fun to be in this car” last night when we met friends for dinner.
What I Don’t Love
I’m just going to get nitpicky here, because I don’t have much to complain about.
The Paint
I love the Diamond Black, and it gets so many compliments. However, it sure does get dirty fast. I feel like I’m going to have to invest in a car wash membership or set aside time each week to clean it. This is not a Tesla-specific problem, of course.
Climate Control
Another “first-world problem,” but sometimes I do have trouble getting the A/C to go right where I need it. I feel like, to feel the air, I have to put the fan speed to 7 or higher.
Swing Mode has been a real savior in this sense, but my Fiancè sometimes complains that my cold air will hit her when she’s already freezing. I think this is just something I need to get used to, as the vents are significantly different than any other car. It’s really not that bad, but it is worth mentioning that we’ve both said we are still adjusting to it early on.
Cybertruck
Tesla brings closure to head-scratching Cybertruck trim

Tesla has ended the production and sale of a Cybertruck trim level that had many people scratching their heads. The move comes after slow sales on the trim, as many Cybertruck buyers opted for other configurations that seemed to be a better value for the money.
On Friday, Tesla officially brought closure to the Long Range Rear-Wheel-Drive configuration of the Cybertruck, a build that was introduced earlier this year at a lower price point than its All-Wheel-Drive counterparts, but missed many of the key features that made the Cybertruck, the Cybertruck.
Rolling the variant out at a price of $69,990, only $10,000 less than that of the All-Wheel-Drive configuration. However, it was also void of many other things:
- Single Motor
- Textile Seats instead of Leather
- 7-Speaker Audio System instead of 15-Speakers
- No Rear Touchscreen
- No Powered Tonneau Cover for Truck Bed
- No 120v/240v outlets
For $79,990, just $10,000 more, owners could receive all of these premium features, plus a more capable All-Wheel-Drive powertrain, which truly made this Rear-Wheel-Drive build of the Cybertruck a sitting duck for criticism.
It was simply not enough meat for the price, and demand was evidently low. From those I spoke to, orders were few and far between; people simply found more value in the All-Wheel-Drive configuration based solely on the additional motor. Adding all the premium interior and functionality features made it a no-brainer.
In a way, it seems Tesla was overly optimistic about the Rear-Wheel-Drive configuration of the Cybertruck, but even after it was launched, plenty of loyal fans were confused by it:
AWD worth $10k more imo
— Zack (@BLKMDL3) April 11, 2025
Sorry. It just isn’t worth that much. I would buy the dual motor at that price, before incentives. I guess I’ll just have to wait longer. The old F150 still runs good. There is nothing compelling at that price point.
— Cat Herder (@Christo87184657) April 11, 2025
The Cybertruck is a great vehicle, and it is among the best vehicles in the company’s lineup. However, it really missed a price point for the Rear-Wheel-Drive configuration that was effective enough to drive people toward it. Many said they would have considered it if Tesla could have brought the price down into the high $40,000 or low $50,000 range.
I took a Tesla Cybertruck weekend Demo Drive – Here’s what I learned
It seems it just did not have the appeal to keep up. Now, Tesla has the All-Wheel-Drive and Cyberbeast for $72,490 and $114,990, respectively.
