CEO Elon Musk has revealed more details about SpaceX’s plans to build and launch upgraded “VisorSat” Starlink satellites, part of the company’s work to ensure that the internet constellation can coexist with astronomy.

Back on April 22nd, Musk gave us the best glimpse yet of what he previously described as a sort of deployable sunshade for Starlink satellites. Designed to prevent orbital sunlight from reflecting off of each spacecraft’s shiny surfaces and disrupting ground-based astronomical observations, the SpaceX CEO said that the company’s very next Starlink launch – scheduled no earlier than “early May” – will carry one or several satellites with said sunshade installed, playfully nicknamed “VisorSat”.

Ultimately, Musk explained in significant detail the likely culprit of the spectacular visibility of Starlink satellites from the ground, discussed plans to reduce or wholly remove that flaring, and explicitly stated that SpaceX will do everything in its power to prevent its constellation from impacting science.

On April 22nd, Musk revealed that the sunshade he’d previously discussed would look “a lot like a car sun visor” and would be built out of dark, radio-transparent foam to avoid disrupting each satellite’s antennas while still preventing sunlight from reflecting off of their mirror-like surfaces.

Days later, he revealed a rough render of VisorSat’s design, showing an extremely simple pair of rotating foam ‘visors’ explicitly shaped to block sunlight from Starlink satellite antennas and not much else. Given the use of foam and a deployment mechanism no more complex than four actuating hinges, it’s entirely believable that this solution – if it works – could be cheap and light enough to be almost irrelevant for the overall spacecraft.

If it works, SpaceX’s ad hoc visor would effectively be the best possible solution for brightness, fully solving the issue while having a near-zero impact on the cost or functionality of each internet satellite. Of course, SpaceX will do what it’s known for and flight-test the new VisorSat design before getting ahead of itself, but if those tests are successful, it would be unsurprising if every future Starlink satellite features a visor.

However, in the process of explaining why Starlink satellites can appear so bright, Musk also hinted at one of the reasons that a visor alone cannot fully solve all of the sources of Starlink’s ground astronomy impact. After launch, Starlink satellites must raise and circularize their orbits to reach an operational altitude, a process that has typically taken 2-4 weeks. During that orbit-raising phase, Musk revealed that Starlink satellites must orient themselves in such a way that the entirety of their front and rear faces – including the solar array – is angled perfectly to reflect sunlight back to Earth.

To alleviate that issue, Musk has said that SpaceX will tweak the orientation and operation of satellites during the orbit raising period, but it’s difficult to see a way to consistently prevent bright reflections without big changes. If SpaceX can’t immediately find a way around that “Open Book” orientation, there will likely be anywhere from 60-180+ Starlink satellites raising their orbits on any given day if the company truly plans to operate a constellation of ~4400 satellites, let alone ~12,000 or ~40,000.

Once orbit-raising is complete, Musk believes that visors will effectively make Starlink satellites invisible to the naked eye, but more work will have to be done if SpaceX wants to fully mitigate Starlink’s astronomy impact.

Tesla Roadster’s new patent preps white-knuckle speeds, keeping it grounded

Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.

The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.

Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.

The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.

The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.

Tesla Roadster event requires restricted airspace, and the FAA obliges

The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.

There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.

These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.

Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.

It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.

Tesla showrooms picked clean ahead of Q3 end as demand looks strong

Tesla (NASDAQ: TSLA) showrooms have been picked clean ahead of the end of the third quarter of the year, as demand looks to be strong and delivery estimates for new vehicles are pushed into late 2026 and early 2027.

Tesla appears to have sold out of many of its Model 3 and Model Y trim levels in the United States, as only the Model Y RWD and Model Y All-Wheel-Drive are available for delivery before the end of the year.

Additionally, many showrooms are either completely empty or void of all but just one demo unit within the buildings themselves in an effort to bolster what could be one of Tesla’s best quarters in vehicle deliveries in recent memory.

Additionally, when I spoke to the guys at Tesla Mechanicsburg two weeks ago, when I returned the Model Y L, their third hauler of the week had just arrived, and every vehicle on it, along with every vehicle in their delivery lot, was accounted for and had a name attached to it for delivery.

Tesla saw a 25 percent increase in deliveries in Q2 compared to the same quarter the year before. The vast majority of the 480,126 units it delivered, 467,762 vehicles to be exact, were the Model 3 and Model Y.

In Q3 2025, Tesla delivered 497,099 vehicles, once again a figure that was dominated by the company’s two mass-market vehicles. Analysts have unusually wide predictions for this quarter, likely because so many firms missed the Q2 delivery figure by such a substantial margin; Wall Street predicted 408,000 cars, while Tesla delivered 480,000.

Goldman Sachs has Tesla slotted for 435,000 deliveries in Q3, while JPMorgan said it anticipates 482,000. The median guess is about 449,000 deliveries for Q3.

Watch Tesla’s “guardian angel” FSD feature take over for collision evasion

Published

Tesla’s Automatic Collision Evasion feature can be seen in one of the first owner videos of it in action.

Tesla owner Spencer (@scotsrule08) posted on Monday that the feature “worked flawlessly,” saying FSD reengaged itself just as he was about to hit a curb. Ashok Elluswamy, who leads Tesla’s AI team, shared the clip and wrote, “A guardian angel always looking out for you.”

The video arrives in the middle of a staged rollout. Tesla first shipped Automatic Collision Evasion with FSD (Supervised) v14.3.9 in software update 2026.27.6 earlier this month, which Teslarati covered as it reached cars. Update 2026.27.10, which began going out on September 19, carried the feature improvements with FSD v14.3.10, according to release notes tracked by Not a Tesla App. The newer 2026.27.11 build is now reaching another wave of vehicles.


The feature only runs on HW4 vehicles, and it requires an active FSD purchase or subscription with both FSD (Supervised) and Automatic Emergency Braking enabled. HW3 owners receive FSD v14.2 Lite in the same updates, but that build does not include collision evasion.

Tesla’s release notes describe two triggers. The first is an imminent frontal collision that braking alone may not prevent, in which case the car can activate FSD to steer, brake or accelerate around the hazard. That scenario is limited to highways below 85 mph, with no pedestrians or cyclists detected and no slippery road surface. The second covers a driver who appears inattentive, such as reaching into the back seat, or who seems to have switched off FSD by accident. Spencer’s curb clip appears to fall into that second category.

Tesla plans big safety improvements for Full Self-Driving v15

Once the system takes over, the accelerator is muted and light brake input will not cancel the maneuver. Drivers need to apply firm, deliberate steering force to take back control, and the car chimes to hand control back once the danger has passed.

Elluswamy recently noted that earlier hazard prediction, faster reaction time and better collision avoidance would arrive with FSD v15, the next major version.
