SpaceX Falcon 9 booster spied on highway as triple-satellite launch moves right
A SpaceX Falcon 9 booster was spotted heading north from the company’s Hawthorne, California factory on January 22nd, signifying a likely shipment of the flight-proven rocket that will help launch Canada’s trio of Radarsat Constellation Mission satellites.
Delayed from mid-February to early March 2019 after an unplanned landing anomaly damaged the Falcon 9 originally assigned to the mission, the shipment of a different booster to Vandenberg Air Force Base (VAFB) helps to narrow down the rocket now likeliest to launch the Canadian Space Agency’s (CSA) radar satellite constellation.

Do the Booster Shuffle!
Thanks to a hydraulic pump failure that led Falcon 9 B1050 to land (albeit softly and in one piece) in the Atlantic Ocean last December, the imminent launch of two booster-dense Falcon Heavy missions, and the thus far schedule-shy orbital launch debut of Crew Dragon, SpaceX’s fleet of available boosters – all flight-proven – can be succinctly summarized as “B1046 thru B1049”.
B1050’s future is uncertain after suffering a smashed interstage and soaking in salt water for several days, while B1051 is definitively assigned to Crew Dragon’s orbital launch debut, known as Demo-1 (DM-1). Falcon 9 B1052 and B1053 are unknown quantities and B1054 was expended after a high-value US Air Force launch, also SpaceX’s final mission of 2018. It’s probably safe to bet that B1052, B1053, and B1055 will be the next three boosters to support a Falcon Heavy launch (or two), currently NET March and April 2019. All three of those Falcon Heavy (FH) boosters have completed static fire tests in Texas and both side boosters arrived at SpaceX’s Florida facilities within the last ~6 weeks.

Assuming that Falcon Heavy Flight 2 and 3 use the same exact boosters, SpaceX production technicians and engineers may already be nearing the completion of another Falcon 9 booster (B1056, presumably) at the Hawthorne factory, although they are likely 1-2 weeks away from that milestone. If, Falcon Heavy Flight 3 (presumed to be the USAF’s STP-2 mission) does not reuse all three first stage boosters from Flight 2 (commercial payload Arabsat 6A), then Hawthorne will have to build, ship, and test anywhere from 1-3 additional boosters between now and April 2019. In the latter scenario, all unflown – mid-build or completed – Falcon boosters would be ‘claimed’ between now and March or April.
Put in another way, short of opting for a delay that could stretch 1-4 months or longer, the Canadian Space Agency (CSA) and Radarsat prime contractor MDA will have to accept one of SpaceX’s flight-proven Falcon 9s.
Falcons on wheels
Thanks to SpaceX’s trusty and well-worn method of using good old trucks and roads to transport Falcon 9 and Heavy boosters, upper stages, fairings, landing legs, and much more cross-country, spaceflight fans have long taken advantage of opportunities – rare and fleeting as they might be – to spot and track SpaceX hardware on public roads. Put simply, a lot of people are excited about SpaceX or are at least familiar and curious enough to know someone to share a photo or observation with. As a result, the community averages dozens of ‘core spottings’ per year. With a little intuition, the process of elimination, a few sources, and some wild guesses, this allows unofficial fans to (very roughly) paint a picture of SpaceX’s fleet of rockets.

For example, the Falcon 9 spotted in Valencia, CA on January 22nd by Reddit user intamin1 could theoretically be any SpaceX booster currently in existence. By knowing the rough state of SpaceX’s fleet (as described above) and observing that the booster was northbound between Hawthorne, CA (the factory) and Vandenberg Air Force Base (VAFB) on Jan 22, a great deal can be intuited. Bound for SpaceX’s West Coast launch complex (SLC-4), it ought to be flightworthy. Knowing that a Falcon Heavy center booster was on SpaceX’s McGregor, Texas static fire stand on January 10th means that the spotted booster can’t (or at least shouldn’t) be coming from Texas, as Falcon Heavy has no known launches planned from VAFB. The process of testing, inspecting, and preparing Falcon boosters for cross-country shipment is also not easily rushed.
On the East Coast, SpaceX needs to launch communications satellite PSN-6 and Spaceflight rideshare GTO-1 in mid to late February. With no new boosters expected to be easily available for months and PSN-6/GTO-1 already entering into the phases of payload fueling, integration, and fairing encapsulation, it can be all but guaranteed that a flight-proven booster was assigned to the mission months ago and is now nearly ready for its third flight somewhere in Cape Canaveral, FL.

Given that B1046 and B1049 are on the West Coast after conducting launches from VAFB and that B1050 is out of circulation for the time being, only B1047 and B1048 remain (in theory) on the East Coast, both having flown two missions. B1048 was recently spotted and confirmed in photos of SpaceX’s Pad 39A integration hangar, although Falcon 9 B1051 and the first orbit-ready Crew Dragon were the center of attention.
B1047 completed its second launch in mid-November 2018 and returned to one of SpaceX’s Florida hangars for refurbishment around Nov 21. Unless any number of locals and bystanders somehow missed it, neither booster has left the Cape since arriving. Meanwhile, B1048 is currently the best-known candidate at hand for SpaceX’s Crew Dragon In-Flight Abort (IFA) test, expected to occur no earlier than spring 2019 and entirely dependent upon the successful launch, reentry, recovery, and refurbishment of the DM-1 capsule to proceed. As a result, the only booster that is realistically available for PSN-6/GTO-1 is Falcon 9 B1047 for what would be its third launch.
Few of my favorites from today's Pence visit to #SpaceX pad 39A. In first photo, from left to right: Previously flown B1048, booster for DM-1, Crew Dragon for DM-1. Look at the size of that Merlin engine bell.

Assuming B1048 did not manage to make it from Cape Canaveral to Central California without a single spotting, the only rockets available for the RCM mission are B1046 and B1049. B1049 completed its second launch – Iridium-8 – just weeks ago and returned by drone ship to Port of LA on January 13th, whereas Falcon 9 B1046 – after completing its historic third launch – completed recovery and was snug in a Hawthorne, CA refurbishment bay by December 17th, 2018. Going off of Occam’s Razor, B1046 is the clear victor for the launch of RCM, although a ~60-90-day turnaround for the already thrice-flown booster could be a stretch. B1049, however, would have barely a single month for refurbishment and inspections.
In the last week or two, RCM stakeholders were provided an updated launch target, delaying the mission by approximately two weeks to a window that begins February 28th with the implication being that the launch is now expected NET early March. If that date is recent and from SpaceX, B1046 is the most practical option, with B1049 thus filling its refurbishment bay in Hawthorne, CA around the same day. If a risk of a 30-day or greater delay is tolerable for CSA and MDA, then B1049.3 would likely be a more optimal fit for their risk tolerance profile. Time will tell!

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 design uses electrically driven ducted fans, typically shown as a row of four at the rear, powered by the vehicle’s high-voltage battery.
The fans pull air from an underbody inlet, route it through ducts, and expel it from a larger rear outlet that functions as a… https://t.co/CHQB9u9UA3 pic.twitter.com/QVXmWTdggh

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.
I’m at Tesla right now and when I walked into their showroom I was shocked to see it basically empty.
I asked one of the people working there where all of the cars are “Gone – it’s the end of the quarter and we’ve sold out of everything… including the display vehicles”So… pic.twitter.com/rN7s3gE6sJ

All the cars are gone from Tesla Century City!
All they have is Model Y L, a self-driving video playing on the background. I guess the best product is no product. Either that or they just sold the showroom cars. pic.twitter.com/mzCjWaXwww

Show room is empty. I asked and they have sold the demo cars too. Delivery numbers better be outstanding! pic.twitter.com/jq5N28Q6tZ

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.
Talking to the guys at the Mechanicsburg showroom on Friday, they couldn’t believe they had ANOTHER hauler coming in of cars for delivery—and each was accounted for
No car just sitting in inventory. They’re expecting a BIG quarter, and this is more than just the Y L https://t.co/ce801GkKVv

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
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 new Automatic Collision Evasion feature worked flawlessly! FSD reengaged itself just as I was about to hit a curb.
Kudos @Tesla_AI team! 👏 pic.twitter.com/Fbp15HhpL2
— Spencer (@scotsrule08) September 28, 2026
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.
