NASA captures closest asteroid flyby of Earth ever recorded

Published

on

Over this past weekend, an SUV-sized asteroid passed Earth in the closest flyby of its type on record. Traveling at about 8 miles per second and measuring about 10-20 feet, the tiny rock came about 1800 miles above the Indian Ocean before heading back into deep space.

NASA’s scientists didn’t detect the asteroid until it was already on an outbound trajectory, which may sound worrisome, but it’s actually a common case. Near Earth Asteroids (NEAs) are notoriously difficult to catch on a telescope, and most pass by safely albeit much farther away. In the case of this NEA, named 2020 QG, an impact would have resulted in an exceptionally bright meteor of which there are numerous occurrences every year.

“It’s quite an accomplishment to find these tiny close-in asteroids in the first place, because they pass by so fast,” said Paul Chodas, director of the Center for Near-Earth Object Studies (CNEOS) at NASA’s Jet Propulsion Laboratory in California. As a bonus, the object’s proximity enabled scientists to watch Earth’s gravity bend its travel path. “Our calculations show that this asteroid got turned by 45 degrees or so as it swung by our planet,” Chodas detailed in NASA’s announcement of the discovery.

NEA 2020 QG was first captured six hours after its closest approach to Earth, at 12:08 a.m. EDT on Sunday, by the Zwicky Transient Facility, a sky-scanning survey telescope based at Caltech’s Palomar Observatory in San Diego County. The asteroid’s image appeared as a long streak of light against an otherwise static and starry sky.

While the smallest Near Earth Asteroids don’t pose a serious threat to Earth’s inhabitants, there’s a bit of a size difference between those tiny space rocks and their more dangerous relatives before detection is better accomplished. Objects measuring about 460 feet and above have a slower rate of motion across the sky and thus more easily captured by available instruments. NASA was given a goal in 2005 of finding 90% of NEAs in this larger size range.

SpaceX CEO Elon Musk has expressed his concern for Earth impact events on numerous occasions, even citing it as a primary reason for humans to become a multiplanetary species. “Asteroid impact risk is well understood, but not comets. Those worry me,” he recently wrote on Twitter. Notably, humans still don’t have the technology to divert any Earth-bound space rocks – frozen or otherwise – from causing a disaster scenario. However, NASA and its international partners have a few missions in place with solving this issue in mind.

This tiny Tesla Cybertruck adjustment has big advantages

Yesterday, we reported on Tesla Cybertruck getting some major adjustments from a manufacturing standpoint in an effort to make the all-electric pickup more cost-effective, more reliable, more serviceable, and more easily produced.

Tesla Cybertruck engineer reveals new changes in ‘constantly evolving’ pickup

One of those changes was the addition of a self-reinforcing polypropylene aero shield that sits underneath the truck. Previously, Tesla utilized aluminum for this, but the self-reinforcing polypropylene was more durable while also being cheaper and lighter.

Tesla has revealed another small change it made to the Cybertruck, and it has to do with the side repeater cameras.

Tesla does not wait for a new model year to improve its vehicles. On September 8, Cybertruck lead engineer Wes Morrill posted side-by-side photos of an updated side repeater camera housing now rolling off the line at Gigafactory Texas.

The triangular camera pod mounted on the front fender looks almost identical at first glance. A closer look reveals a revised contour that uses the air already flowing around the truck to keep the lens clearer in rain and road spray.

The side repeater cameras sit in an exposed position on the Cybertruck’s angular stainless-steel body.

In wet weather, they readily collect water droplets that can degrade the image Autopilot and Full Self-Driving use for lane changes and blind-spot monitoring. Early production trucks sometimes left owners wiping lenses by hand or accepting temporary restrictions on driver-assistance features.

Tesla has added washers to cameras on certain other models and on Cybercab prototypes, but those active systems add cost, complexity, and extra potential leak points.

The new housing solves the problem with passive geometry. Subtle changes in the surround create localized airflow disturbances as the vehicle moves. Those eddies physically push water droplets away from the optical surface. Morrill called the result “pure vision improvement” achieved at “no cost penalty.” Once the production mold is updated, every subsequent part costs the same as the original.

The advantages compound quickly. Clearer cameras in rain improve the reliability of driver-assistance features precisely when they are needed most. The design consumes no extra energy and introduces no new failure modes.

New Cybertrucks built after the tooling changeover receive the updated part automatically. Some owners of trucks delivered as late as June 2026 have already confirmed they received the revised housing. Retrofit questions have appeared in replies, and the cameras appear electrically compatible, though Tesla has not announced an official service program.

A few millimeters of reshaped housing will not make headlines the way a new battery pack does, but these changes are incremental and increase the Cybertruck’s effectiveness as a vehicle over time.

This improvement illustrates how Tesla continues to refine the Cybertruck after volume production began. Better wet-weather vision, zero added cost, and no extra hardware add up to a meaningful gain in everyday usability and safety.

Tesla is rolling out a new FSD version with a massive safety addition

Tesla is rolling out a new version of its Full Self-Driving suite to some owners that comes with the massive addition of a safety feature.

Tesla is rolling out Automatic Collision Evasion with the 2026.27.6 Software Update, which started rolling out to some vehicles last night. We received the update, along with Full Self-Driving v14.3.9, as well as v14.2 Lite, which has identical release notes as the previous version and seems to have some refinements and improvements in behavior and performance.

However, most of the attention has fallen on the Automatic Collision Evasion feature, which we covered in an article last week.

The function will activate Full Self-Driving to “try to keep your vehicle safe and then continue driving. It can engage in the following situations while you are driving manually:

  • Scenario 1: A frontal collision is imminent and braking alone may not avoid it.
  • Scenario 2: Your vehicle detects that you are not sufficiently attentive to the road (for example, reaching toward the back seat), or that Full Self-Driving (Supervised) may have been unintentionally disengaged.”

Essentially, FSD will take over when the vehicle determines you are not paying sufficient attention or are heading toward a potential collision. The addition of this feature is incredibly useful as distracted driving is a major issue in today’s world.

Along with the new safety feature is Tesla FSD v14.3.9, which has no additional release notes compared to the previous version, but in my first drives, my first impression is that operation is great, and parking is still sort of a pain point.

Additionally, Tesla v14.2. Lite has arrived. A great review of that is available here:

The addition of an Automatic Collision Evasion feature is similar to that of other collision avoidance systems that are used by companies like Hyundai, Kia, and Genesis. These programs typically utilize radar and camera sensors to apply emergency brakes autonomously, though evasive steering in a manual driving mode is pioneered primarily by Tesla’s newest addition.

Tesla primes Cybercabs for 4K streaming and high bandwidth gaming with Starlink integration

Tesla is now shipping Cybercabs from Giga Texas with Starlink hardware built in as standard.

Tesla’s Cybercabs are now leaving Gigafactory Texas with Starlink hardware on the rear hatch in significant numbers, according to drone footage captured Tuesday by longtime Austin drone observer Joe Tegtmeyer. Production at the factory ramped back up after the Labor Day weekend, and his flyover of the outbound lot showed rows of gold Cybercabs alongside Model Y Long Wheelbase units, many carrying the satellite module for the first time as standard equipment rather than a one off retrofit.

Tesla first showed Starlink built into an actual Cybercab on August 10, when the Robotaxi account posted images of a single gold unit with the antenna integrated into the roofline above the taillights and called it the first Cybercab with Starlink integration. That followed a July reveal where Tesla and Starlink jointly posted a cutaway diagram of the antenna placement without a working vehicle to back it up. Ashok Elluswamy, Tesla’s VP of AI software, said at the time that the connection isn’t required for the car to drive itself. It exists mainly for navigation, customer service and keeping tabs on the fleet.

Musk has made a different case in public. During Tesla’s Q2 earnings call, he said the company can’t afford robotaxis stranded in what he called “Bermuda Triangles of lack of cellular connectivity,” and he separately claimed on X that Starlink will eventually reach every Tesla built, calling it the only way to deliver high bandwidth to billions of vehicles. He has also pitched the antenna as an entertainment upgrade, telling riders they would be able to stream 4K video or play games during a trip.

The rollout has moved fast since. Robotaxi service opened to the public in Austin on September 3, and Cybercabs had already been spotted with Starlink hardware in Houston and near Miami International Airport in the weeks before Tuesday’s factory footage showed the module shipping at volume rather than on scattered test units. Whether the satellite link earns its keep is still an open question. Tesla’s unsupervised service currently runs in dense metro geofences in Texas and Florida, markets where cellular coverage is already strong, which is not where the rural dead zones Musk describes tend to show up.
