NASA is crashing a satellite into an asteroid to gather data about asteroid deflection
The threat of asteroids crashing into Earth isn’t a new concern. We’ve been warned about it by science fiction authors and Hollywood alike, and any kid that’s ever paid attention to dinosaurs in school knows there are bad outcomes when life and chunks of space rock meet up. The space agencies of Europe and the United States are not blind to the threat, thankfully, and they have a multi-part satellite mission in the works directed to gathering real data on how to redirect an asteroid with bad intentions for our planet, i.e., is on a collision course. Specifically, they’re planning on crashing one satellite into an asteroid and studying the effect with another satellite run by the European Space Agency (ESA).
NASA’s part of the mission is called the Double Asteroid Redirection Test (DART), and it will serve as the first demonstration of changing asteroid motion in space. The launch window begins in late December 2020, most likely on track for June 2021, for arrival at its targeted asteroid, Didymos, in early October 2022. Didymos is Greek for “twin”, the name being chosen because it’s a binary system with two bodies: Didymos the asteroid, about a half mile across, and Didymoon the moonlet, about 530 feet across, acting as a moonlet. The two currently have a Sun-centric orbit and will have a distant approach to Earth around the same time as DART’s launch window and then again in 2024.
After reaching the asteroid, DART will enter orbit around Didymoon, and crash into it at a speed of about 4 mi/s (nine times faster than a bullet) to change its speed by a fraction of one percent, an amount measurable by Earth-based telescopes for easy study. Unsurprisingly, the preferred description is “kinetic impact technique” rather than “crash” – maybe even “impact” or “strike”, if we’re avoiding terms that sound random or accidental. The mission is being led by the Johns Hopkins Applied Physics Laboratory (JHU/APL) and managed by the Planetary Missions Program Office at Marshall Space Flight Center in Alabama for NASA’s Planetary Defense Coordination Office.
NASA’s DART mission is one of two parts of an overall mission dubbed AIDA (Asteroid Impact & Deflection Assessment). Joining the agency’s Earth-protection venture is the ESA with its Hera spacecraft, named after the Greek goddess of marriage, a probe that will follow up DART’s mission with a detailed survey of the asteroid’s response to the impact. Collected data will help formulate planetary defense plans by providing detailed analysis from DART’s real-time asteroid deflection experiment. Its launch is scheduled for 2023.
Just this month, another part was added to Hera’s mission: CubeSats. This class of tiny satellites is about the size of a briefcase, and they recently made their deep space debut during NASA’s Mars InSight landing. During that mission, twin CubeSats collectively named MarCO followed along on the journey to Mars behind InSight, eventually relaying data during the landing event back to NASA’s Mission Control along with a photo of the red planet. ESA’s CubeSats, named APEX (Asteroid Prospection Explorer) and Juventas, will travel inside Hera, gather data on Didymos and its moonlet, and then both will land on their respective rocks and provide imaging from the surface.
Just to recap: Tiny satellites in a class that students and startups can and have developed and launched will travel into deep space and land on asteroids. This is big news for the democratization of space travel. As emphasized by Paolo Martino, Hera’s lead engineer in ESA’s article announcing the CubeSat mission, “The idea of building CubeSats for deep space is relatively new, but was recently validated by NASA’s InSight landing on Mars last November.”
Using kinetic energy – pure ram/crash force – isn’t the only option NASA is looking at for defending Earth from incoming asteroids. A “gravity tractor” concept would orbit a craft in a way that would change the trajectory due to gravitational tugging. Similar to how our moon has an impact on our tides or the Earth makes the Sun wobble ever so slightly, a satellite orbiting an asteroid would give pushes and pulls to set its course elsewhere.
Unfortunately, a gravity tractor likely wouldn’t be very effective for asteroids large enough to seriously threaten our planet. Also, the techniques for achieving it would require decades to develop and test in space. Laser ablation, or using spacecraft lasers to vaporize asteroid rock to change an asteroid’s course, is another technique NASA has considered, but it might be just as feasible or cost-effective to simply launch projectiles to achieve the same purpose.

Tesla Giga Berlin dispute against IG Metall union leads to investigation
As per a report from rbb24, police seized a laptop belonging to an IG Metall member at Tesla Giga Berlin on Tuesday afternoon.
German authorities have opened an investigation into an IG Metall union representative following allegations that a confidential works council meeting at Tesla’s Gigafactory Berlin was secretly recorded. The probe follows a criminal complaint filed by Tesla management last week.
As per a report from rbb24, police seized a laptop belonging to an IG Metall member at Tesla Giga Berlin on Tuesday afternoon. Prosecutors in Frankfurt (Oder) confirmed that an investigation is underway into a possible unauthorized audio recording of an internal works council meeting.
Under German law, recording a non-public meeting without consent may constitute a criminal offense.
Tesla stated that Gigafactory Berlin employees alerted management after allegedly discovering that an external union representative, who was attending the event as a guest, had recorded the session. Plant manager André Thierig stated in a post on X that the representative was “caught in action,” prompting the company to contact police and file a criminal complaint.
The seized device is now part of the investigation, and authorities will determine whether any unlawful recording had indeed occurred.
IG Metall has denied the accusation. In comments to German media, representatives rejected Tesla’s claim and described the electric vehicle maker’s allegation as an election campaign tactic ahead of upcoming works council elections.
The election at Tesla’s Grünheide plant is scheduled for March 2–4, 2026, with about 11,000 employees being eligible to vote. Regular works council elections in Germany are held every four years between March and May.
The incident comes amid tensions between Tesla and organized labor in Germany. While works councils operate independently from unions, IG Metall has been active at the plant and has previously criticized Tesla’s labor practices. Authorities, for their part, have not yet announced whether charges will be filed, though the investigation remains ongoing.

Tesla rolls out xAI’s Grok to vehicles across Europe
The initial rollout includes the United Kingdom, Ireland, Germany, Switzerland, Austria, Italy, France, Portugal, and Spain.
Tesla is rolling out Grok to vehicles in Europe. The feature will initially launch in nine European territories.
In a post on X, the official Tesla Europe, Middle East & Africa account confirmed that Grok is coming to Teslas in Europe. The initial rollout includes the United Kingdom, Ireland, Germany, Switzerland, Austria, Italy, France, Portugal, and Spain, and additional markets are expected to be added later.
Grok allows drivers to ask questions using real-time information and interact hands-free while driving. According to Tesla’s support documentation, Grok can also initiate navigation commands, enabling users to search for destinations, discover points of interest, and adjust routes without touching the touchscreen, as per the feature’s official webpage.
The system offers selectable personalities, ranging from “Storyteller” to “Unhinged,” and is activated either through the App Launcher or by pressing and holding the steering wheel’s microphone button.
Grok is currently available only on Model S, Model 3, Model X, Model Y, and Cybertruck vehicles equipped with an AMD infotainment processor. Vehicles must be running software version 2025.26 or later, with navigation command support requiring version 2025.44.25 or newer.
Drivers must also have Premium Connectivity or a stable Wi-Fi connection to use the feature. Tesla notes that Grok does not currently replace standard voice commands for vehicle controls such as climate or media adjustments.
The company has stated that Grok interactions are processed securely by xAI and are not linked to individual drivers or vehicles. Users do not need a Grok account or subscription to enable the feature at this time as well.

Tesla ends Full Self-Driving purchase option in the U.S.
In January, Musk announced that Tesla would remove the ability to purchase the suite outright for $8,000. This would give the vehicle Full Self-Driving for its entire lifespan, but Tesla intended to move away from it, for several reasons, one being that a tranche in the CEO’s pay package requires 10 million active subscriptions of FSD.
Tesla has officially ended the option to purchase the Full Self-Driving suite outright, a move that was announced for the United States market in January by CEO Elon Musk.
The driver assistance suite is now exclusively available in the U.S. as a subscription, which is currently priced at $99 per month.
Tesla moved away from the outright purchase option in an effort to move more people to the subscription program, but there are concerns over its current price and the potential for it to rise.

Although Tesla moved back the deadline in other countries, it has now taken effect in the U.S. on Sunday morning. Tesla updated its website to reflect this:

There are still some concerns regarding its price, as $99 per month is not where many consumers are hoping to see the subscription price stay.
Musk has said that as capabilities improve, the price will go up, but it seems unlikely that 10 million drivers will want to pay an extra $100 every month for the capability, even if it is extremely useful.
Instead, many owners and fans of the company are calling for Tesla to offer a different type of pricing platform. This includes a tiered-system that would let owners pick and choose the features they would want for varying prices, or even a daily, weekly, monthly, and annual pricing option, which would incentivize longer-term purchasing.
Although Musk and other Tesla are aware of FSD’s capabilities and state is is worth much more than its current price, there could be some merit in the idea of offering a price for Supervised FSD and another price for Unsupervised FSD when it becomes available.
