NASA is crashing a satellite into an asteroid to gather data about asteroid deflection

Published

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 details plan for increased Model Y pricing stability in Australia

As Chinese automakers increasingly deploy low-priced EVs in the Australian market, one Tesla executive explains one way the company plans to stay competitive.

A Tesla executive managing the Australian and surrounding markets has detailed the company’s plans to move away from rapid pricing changes with the arrival of the new Model Y, especially as electric vehicle (EV) competition from other Chinese automakers arrives in Australia and surrounding markets.

Thom Drew, Tesla’s Country Director for New Zealand and Australia, said in an interview with Chasing Cars on Friday that the recently refreshed Model Y will make it to Australian markets with more consistent pricing. The statement comes after the Model Y remained Australia’s best-selling EV in 2024, and he says that the era of the Tesla price war seems to be winding down as the SUV gets more affordable.

“We are certainly not going to get into price wars,” Drew said. “I know we have famously been known for changing our prices rapidly over the past several years.

“I really think we have gotten to a point with our pricing where it is where it should be. Once we release the general production pricing for Model Y, I think we are at a really good point. Particularly with the refinements on the [upgraded] vehicle, it is exceptional value for money.”

First deliveries of the Launch Edition Model Y refresh are expected in May, and Drew says initial shipments will be large in volume to match significant demand for the EV. The executive also confirmed that the highly-coveted rear-wheel-drive (RWD) model, the Launch Edition of which is currently sold out, will go on sale again as the regular edition in the weeks to come.

It’s not clear at this time if Tesla plans to employ similar strategies in markets beyond the Asia-Pacific, though Drew highlights the pricing stability efforts as a necessary measure to remain competitive amongst incoming EVs from Chinese automakers. Between this and optimizing consumer experiences by making great vehicles, the executive explains that the company remains intent on holding onto its number one seller spot.

“We need to make sure we are hyper-focussed on the quality of our products and our competitiveness,” he says. “[We need to] be looking around today and making sure that we have the best ownership experience to keep our brand at the number-one point.”

At this point, Drew also says that the Model Y is the most affordable option in the Australian market, highlighting that keeping the price stable should hold competitors off for the foreseeable future, at the very least. The news also comes as reports say that Tesla may already be looking to launch an even cheaper Model Y in China, which could make the vehicle even more competitive with future iterations.

“At the moment, there is no cheaper model that I am aware of,” Drew adds. “If there was one, absolutely [we would have our hand up].”

The Australian market requires right-hand-drive (RHD) vehicles, meaning that they drive on the left side of the road and are equipped with steering wheels on the right side of the automobile. Tesla’s Gigafactory in Shanghai supplies the markets in Australia, New Zealand and multiple surrounding regions throughout the Asia-Pacific.

Tesla launched the upgraded Model Y in China in January, after months of speculation that the refreshed SUV would soon be launched. The automaker began initial deliveries of the Launch Edition Model Y refresh in China last month, officially transitioning to the sale of the regular edition of the vehicle at the beginning of March.

Could Tesla vandalism fuel higher insurance prices?

Experts say that vandalism against Tesla vehicles could make insurance companies increase rates—or drop coverage for the brand altogether.

Tesla owners have recently experienced a substantial uptick in vandalism events in protest of CEO Elon Musk and recent developments with the Trump administration, and some say that it could lead to higher insurance rates if it continues.

In a report on Sunday, Insurify Data Journalist Matt Brannon told Newsweek that increased vandalism against Tesla’s vehicles could make insurance companies proactively raise their rates in the future. He says that factors such as theft and vandalism are both major considerations for insurance companies when setting rates, though perhaps not to the extent that collisions are.

“If vandalism involving Tesla vehicles continues to rise and doesn’t go back down, we could see rates rise for comprehensive coverage in the future,” Brannon said.

Vandalism is typically covered by comprehensive policies, though Brannon and Bankrate Insurance Analyst Shannon Martin say that these won’t likely increase rates as much as collisions. However, after a lack of engine immobilizers in certain Kia and Hyundai vehicles made them susceptible to theft, sparking widespread TikTok and Instagram challenges in 2022 in which individuals would try to steal these cars, Martin explains that companies could even refuse to insure Tesla vehicles in extreme cases.

“As we have learned from the 2023 TikTok theft trend targeting certain model Kias and Hyundais, if these types of losses continue, carriers could refuse to offer coverage for Tesla vehicles altogether,” Martin explained.

She also says that many other factors could cause insurance rates to rise organically across the industry, including impending tariffs from the Trump administration that have caused uncertainty in recent weeks. Factors such as high repair costs have also caused rate increases in the past few years, particularly for vehicles that are electric.

However, Martin says the recent string of vandalism against Tesla vehicles could cause even steeper rate hikes throughout 2025, even as some of the company’s vehicles are already fairly expensive to insure in some areas.

“Since the recent rise in vandalism is focused on Teslas and not other make vehicles, drivers who carry Tesla Insurance may see a higher premium hike than those who have coverage with other carriers, since the risk of loss isn’t as diversified,” she adds.

Brannon says that insurance rates for electric vehicles (EVs) increased twice as fast as those of gas vehicles in 2024, while full-coverage prices on Teslas have increased over the past few years. Newsweek also says it reached out to insurance companies including Allstate, Geico, Progressive, and State Farm, though no comment was given by the time of publishing.

Vandalism against Tesla vehicles in recent weeks

The news comes as Tesla owners have detailed significant increases to vandalism in recent weeks, as many have tried to protest and speak out against cuts from Musk and Trump’s newly developed government efficiency division.

In February, one Cybertruck owner in Massachusetts said he was getting death threats, yelling passersby, stickers placed on his vehicle, and broad cancellations of client appointments following Musk’s controversial salute at the Trump inauguration ceremony. As a result, the doctor, an immigrant from Syria, said he was considering moving away in hopes to escape the verbal and property attacks.

Tesla owners in Northern California a few weeks ago were left with notes on their cars saying to trade or sell them before February 12, or else it would be “open season.” An activist group called Students Against Nazi Extremism (SANE) claimed responsibility for the notes.

Last week, Musk also responded to a story in which a New York individual drew a Swastika on a person’s Cybertruck, saying that, “Naturally, he drives a Subaru.”

Superchargers have also been targeted in recent attacks, including fresh graffiti last month, with vandals writing the word “Nazi” on some charging posts in Utah along with drawing a Swastika. Tesla said in response that it planned to file charges against the vandals.

Widespread protests have also faced Tesla stores in recent weeks, with one in Oregon even being the victim of multiple rounds of gunfire, while multiple Cybertrucks in Seattle were set on fire—an event now being looked at by the Federal Bureau of Investigation (FBI).

Another string of vandalism and arson at a Tesla store in Colorado resulted in the arrest of two suspects in the past few weeks, after the site was repeatedly tagged with graffiti, some of which said “Nazi cars” on the front windows.

A key Tesla safety engineer has departed from the company, as shared earlier this month, following nearly a decade and a half spent working across three of the automaker’s locations.

In a post on LinkedIn last week, Tesla’s Principal CAE Crash Safety Engineer, Petter Winberg, announced his departure from the company after working there for over 14 years. Winberg played a major role in Tesla’s efforts to make its vehicles some of the safest out there, starting as a Senior Tech Specialist in 2011 and slowly getting promoted to his current position.

In his position, Winberg worked on crash architectures for the Cybercab, Semi, and future vehicles, along with the Model S, Model X, Model 3, and Model Y, and developing specific accident architectures once Giga Casting production came into play. The executive’s full departure announcement reads as follows:

Elon, 2011: “I want Tesla vehicles to be the safest on the planet” Me: “Challenge accepted”

Having developed Model S, S-DM, X, 3, Y, Y-SP as well as future crash architectures, I have decided now is the time to move on. Thank you Tesla, keep crushing it! What an incredible team, I will miss you all.

During his time at Tesla, the engineer worked at the company’s engineering headquarters in Palo Alto, California, before moving to the company’s nearby Fremont factory, then finally landing at the automaker’s Gothenburg, Sweden facilities, where he has served in his current position since January 2020. Prior to this, Winberg also worked at Volvo, Saab, Ford, and Volvo.

The post also elicited a handful of comments from colleagues, including one commenter who called Winberg the “master of crash simulations,” and multiple others who praised him for his guidance and knowledge of the subject.

Tesla has also been heavily focused on making its vehicles safe since the early days, as Winberg points out.

As one example in October, Tesla VP of Vehicle Engineering Lars Moravy reiterated this point by highlighting both the company’s active and passive safety features included in the Model Y and other vehicles. Moravy detailed that, while features built-in for the Autopilot and Supervised Full Self-Driving (FSD) systems provide active safety features meant to help prevent crashes, even if “the worst occurs, [Tesla drivers] will be protected by the best passive safety cars on the planet.”

The company’s vehicles have also earned top safety ratings across four different continents at this point, most recently including a five-star safety rating for the Cybertruck from the top auto regulator in the U.S.

Over the last several months, Tesla has also faced executive and high-profile engineering departures a handful of times, as can probably be expected from most companies of its size.

Some examples include the departure of Safety Policy Lead Marc Van Impe and Chief Information Officer Nagesh Saldi in October, VP of Finance and Business Operations Sreela Venkataratnam in August, and both SVP of Powertrain and Energy Engineering Drew Baglino and VP of Public Policy and Business Development Rohan Patel in April, to name just a few.
