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 takes a step towards removal of Robotaxi service’s safety drivers
Tesla watchers are speculating that the implementation of in-camera data sharing could be a step towards the removal of the Robotaxi service’s safety drivers.
Tesla appears to be preparing for the eventual removal of its Robotaxi service’s safety drivers.
This was hinted at in a recent de-compile of the Robotaxi App’s version 25.11.5, which was shared on social media platform X.
In-cabin analytics
As per Tesla software tracker @Tesla_App_iOS, the latest update to the Robotaxi app featured several improvements. These include Live Screen Sharing, as well as a feature that would allow Tesla to access video and audio inside the vehicle.
According to the software tracker, a new prompt has been added to the Robotaxi App that requests user consent for enhanced in-cabin data sharing, which comprise Cabin Camera Analytics and Sound Detection Analytics. Once accepted, Tesla would be able to retrieve video and audio data from the Robotaxi’s cabin.
Video and audio sharing
A screenshot posted by the software tracker on X showed that Cabin Camera Analytics is used to improve the intelligence of features like request support. Tesla has not explained exactly how the feature will be implemented, though this might mean that the in-cabin camera may be used to view and analyze the status of passengers when remote agents are contacted.
Sound Detection Analytics is expected to be used to improve the intelligence of features like siren recognition. This suggests that Robotaxis will always be actively listening for emergency vehicle sirens to improve how the system responds to them. Tesla, however, also maintained that data collected by Robotaxis will be anonymous. In-cabin data will not be linked to users unless they are needed for a safety event or a support request.
Tesla watchers are speculating that the implementation of in-camera data sharing could be a step towards the removal of the Robotaxi service’s safety drivers. With Tesla able to access video and audio feeds from Robotaxis, after all, users can get assistance even if they are alone in the driverless vehicle.

Mizuho keeps Tesla (TSLA) “Outperform” rating but lowers price target
As per the Mizuho analyst, upcoming changes to EV incentives in the U.S. and China could affect Tesla’s unit growth more than previously expected.
Mizuho analyst Vijay Rakesh lowered Tesla’s (NASDAQ:TSLA) price target to $475 from $485, citing potential 2026 EV subsidy cuts in the U.S. and China that could pressure deliveries. The firm maintained its Outperform rating for the electric vehicle maker, however.
As per the Mizuho analyst, upcoming changes to EV incentives in the U.S. and China could affect Tesla’s unit growth more than previously expected. The U.S. accounted for roughly 37% of Tesla’s third-quarter 2025 sales, while China represented about 34%, making both markets highly sensitive to policy shifts. Potential 50% cuts to Chinese subsidies and reduced U.S. incentives affected the firm’s outlook.
With those pressures factored in, the firm now expects Tesla to deliver 1.75 million vehicles in 2026 and 2 million in 2027, slightly below consensus estimates of 1.82 million and 2.15 million, respectively. The analyst was cautiously optimistic, as near-term pressure from subsidies is there, but the company’s long-term tech roadmap remains very compelling.
Despite the revised target, Mizuho remained optimistic on Tesla’s long-term technology roadmap. The firm highlighted three major growth drivers into 2027: the broader adoption of Full Self-Driving V14, the expansion of Tesla’s Robotaxi service, and the commercialization of Optimus, the company’s humanoid robot.
“We are lowering TSLA Ests/PT to $475 with Potential BEV headwinds in 2026E. We believe into 2026E, US (~37% of TSLA 3Q25 sales) EV subsidy cuts and China (34% of TSLA 3Q25 sales) potential 50% EV subsidy cuts could be a headwind to EV deliveries.
“We are now estimating TSLA deliveries for 2026/27E at 1.75M/2.00M (slightly below cons. 1.82M/2.15M). We see some LT drivers with FSD v14 adoption for autonomous, robotaxi launches, and humanoid robots into 2027 driving strength,” the analyst noted.

Tesla’s Elon Musk posts updated Robotaxi fleet ramp for Austin, TX
Musk posted his update on social media platform X.
Elon Musk says Tesla will “roughly double” its supervised Robotaxi fleet in Austin next month as riders report long wait times and limited availability across the pilot program in the Texas city. Musk posted his update on social media platform X.
The move comes as Waymo accelerates its U.S. expansion with its fully driverless freeway service, intensifying competition in autonomous mobility.
Tesla to increase Austin Robotaxi fleet size
Tesla’s Robotaxi service in Austin continues to operate under supervised conditions, requiring a safety monitor in the front seat even as the company seeks regulatory approval to begin testing without human oversight. The current fleet is estimated at about 30 vehicles, StockTwists noted, and Musk’s commitment to doubling that figure follows widespread rider complaints about limited access and “High Service Demand” notifications.
Influencers and early users of the Robotaxi service have observed repeated failures to secure a ride during peak times, highlighting a supply bottleneck in one of Tesla’s most visible autonomy pilots. The expansion aims to provide more consistent availability as the company scales and gathers more real-world driving data, an advantage analysts often cite as a differentiator versus rivals.
Broader rollout plans
Tesla’s Robotaxi service has so far only been rolled out to Austin and the Bay Area, though reports have indicated that the electric vehicle maker is putting in a lot of effort to expand the service to other cities across the United States. Waymo, the Robotaxi service’s biggest competitor, has ramped its service to areas like the San Francisco Bay Area, Los Angeles, and Phoenix.
Analysts continue to highlight Tesla’s long-term autonomy potential due to its global fleet size, vertically integrated design, and immense real-world data. ARK Invest has maintained that Tesla Robotaxis could represent up to 90% of the company’s enterprise value by 2029. BTIG analysts, on the other hand, added that upcoming Full Self-Driving upgrades will enhance reasoning, particularly parking decisions, while Tesla pushes toward expansions in Austin, the Bay Area, and potentially 8 to 10 metro regions by the end of 2025.
