SpaceX has completed its 40th Falcon 9 launch of 2022, delivering a new batch of Starlink satellites and Boeing demonstration satellite into orbit.

Right on schedule, Falcon 9 lifted off from SpaceX’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad at 10:09 pm EDT, Sunday, September 4th. The rocket’s reused booster and fairing and new upper stage performed as expected, continuing Falcon 9’s unprecedented streak of 149 successful launches. Flying for the seventh time overall, former Falcon Heavy booster B1052 performed flawlessly after a quick 31-day turnaround and touched down on SpaceX drone ship Just Read The Instructions’ (JRTI) deck several hundred miles downrange less than nine minutes after liftoff.

Flying for the fourth and fifth times, the Starlink 4-20 mission’s Falcon 9 fairing halves also worked as expected on ascent. SpaceX does not discuss fairing recovery but both halves likely deployed parafoils after reenter Earth’s atmosphere and gently splashed down in the Atlantic Ocean. SpaceX support ship Doug will eventually fish them out of the water for reuse.

Not merely a Starlink mission, Starlink 4-20 was SpaceX’s sixth Starlink rideshare. Sitting atop the stack of 51 Starlink V1.5 satellites was an experimental spacecraft built by Spaceflight Inc. Known as Sherpa-LTC2, Spaceflight and partner Astro Digital turned the orbital transfer vehicle (space tug) into a satellite for customer Boeing. The purpose: carry and test a prototype communications payload built by Astro Digital and designed to verify new V-band communications technologies for a planned constellation of Boeing satellites in Low Earth Orbit (LEO).

The US Federal Communications Commission (FCC) approved Boeing’s plans for a 147-satellite V-band constellation in November 2021. It’s unclear what the purpose of the constellation would be or if Boeing already has customers or partners lined up. The prototype spacecraft built by Spaceflight and Astro Digital – known as Varuna in recent FCC filings – will be crucial for determining the constellation’s future. Boeing wants to use a swath of spectrum known as the V-band that has a higher frequency than the Ku and Ka bands commonly used by most other communications satellites. A higher frequency could mean higher connection speeds and more available bandwidth, but V-band radio waves tend to struggle to pierce through rain and other adverse weather conditions.

Varuna should help Boeing fully determine whether that interference is a showstopper or something that can be managed. Boeing applied for an FCC license for its V-band constellation in 2017. It’s unclear whether a lack of interest on Boeing’s part or problems with the application caused the process to take as long as it did.

Varuna was successfully deployed from Falcon 9 a bit less than 50 minutes later in a mostly circular orbit 316 kilometers (196 mi) above Earth’s surface. Outfitted with a propulsion system designed by startup Benchmark Space, Sherpa-LTC2 is meant to eventually raise itself into an operational orbit around 1050 kilometers (~650 mi), where the V-band payload can be tested at the same altitude as Boeing’s planned constellation.

20 minutes after Varuna’s deployment, Falcon 9’s upper stage – spinning end over end – released all 51 Starlink satellites at once, completing the payload portion of the mission. As always, the upper stage will likely perform a deorbit burn within a few hours of liftoff and should reenter Earth’s atmosphere not long after, ensuring that the only space debris produced by the mission is the Varuna deployment mechanism and a set of four benign Starlink ‘tensioning rods’ that should reenter in about two months.

Starlink 4-20 was SpaceX’s 40th launch of 2022 and 50th launch in 12 months. According to Next Spaceflight, the company has plans for at least two more Starlink launches within the next eight days. Starlink 4-2, another rideshare mission, is scheduled no earlier than September 10th, while Starlink 4-34 could launch on September 12th.

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.
