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!

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.

— Elon Musk (@elonmusk) March 11, 2026
Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.

Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.

Tesla finally brings a Robotaxi update that Android users will love
The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android.
Tesla is finally bringing an update of its Robotaxi platform that Android users will love — mostly because it seems like they will finally be able to use the ride-hailing platform that the company has had active since last June.
Based on a decompile of software version 26.2.0 of the Robotaxi app, Tesla looks to be ready to roll out access to Android users.
According to the breakdown, performed by Tesla App Updates, the company is preparing to roll out an Android version of the app as it is developing several features for that operating system.
🚨 It looks like Tesla is preparing to launch the Robotaxi app for Android users at last!

The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android:
“Strings like notification_channel_robotaxid_trip_name and android_native_alicorn_eta_text show exactly how Tesla plans to replicate the iOS Live Activities experience. Instead of standard push alerts, Android users are getting a persistent, dynamically updating notification channel.”
This is a big step forward for several reasons. From a face-value perspective, Tesla is finally ready to offer Robotaxi to Android users.
The company has routinely prioritized Apple releases because there is a higher concentration of iPhone users in its ownership base. Additionally, the development process for Apple is simply less laborious.
Tesla is working to increase Android capabilities in its vehicles
Secondly, the Robotaxi rollout has been a typical example of “slowly then all at once.”
Tesla initially released Robotaxi access to a handful of media members and influencers. Eventually, it was expanded to more users, so that anyone using an iOS device could download the app and hail a semi-autonomous ride in Austin or the Bay Area.
Opening up the user base to Android users may show that Tesla is preparing to allow even more users to utilize its Robotaxi platform, and although it seems to be a few months away from only offering fully autonomous rides to anyone with app access, the expansion of the user base to an entirely different user base definitely seems like its a step in the right direction.
