[Update] SpaceX rocket launch kicks off a potentially record-smashing year for Falcon 9
Update: After spinning itself around its vertical axis a bit like a propeller, SpaceX’s expendable Falcon 9 upper stage has successfully released a massive stack of 60 Starlink v1.0 satellites for the second time in two months. Designing to tolerate the occasional bump during their bizarre deployment, those 60 satellites will quickly spread out in space and deploy their solar arrays an hour or so after separating from Falcon 9’s upper stage.
Perhaps as early as later this evening or sometime on January 7th, all 60 satellites will fire up their krypton ion thrusters, beginning the process of temporarily raising their orbits to 350 km (220 mi). Once there, SpaceX will more extensively verify the health of each spacecraft and – if all looks well – send all 60 on their way to a final circular 550 km (340 km) orbit where they will join their brethren and begin operating as communications satellites.
A SpaceX Falcon 9 has kicked off what could be a record-smashing year, potentially making SpaceX the world’s most prolific launch company thanks in large part to the game-changing reusability of its Falcon rockets.
At 9:19 pm ET on January 6th (02:19 UTC, Jan 7), Falcon 9 booster B1049’s nine Merlin 1D engines came to lift, lifting the two-stage rocket and its payload of 60 Starlink satellites off the pad and sending them on their way to orbit. Minutes later, the Falcon 9 booster shut off – completing its fourth successful launch in 17 months – and flipped around with small cold-gas thrusters, beginning its trip back down to Earth.
Less than nine minutes after lifting off from SpaceX’s LC-40 pad at Cape Canaveral Air Force Station (CCAFS), Falcon 9 B1049 began its landing burn and gently touched down on drone ship Of Course I Still Love You (OCISLY), stationed more than 600 km (375 mi) downrange in the Atlantic Ocean. Seconds later, the mission’s expendable Falcon 9 upper stage shut off its Merlin Vacuum (MVac) engine, completing the first of two burns and placing the rocket and its Starlink payload in a parking orbit.
Known as Starlink V1 L2, referring to the second launch of Starlink v1.0 satellites, this mission crossed off several SpaceX milestones – both internal and external. For Falcon 9, it marked the company’s 48th successful landing of an orbital-class rocket booster, as well as the second time SpaceX has successfully launched and landed the same booster (this time B1049) four times in a row.
Even more significantly, it’s almost certain that – so long as all 60 Starlink V1 L2 satellites successfully deploy and begin orbit-raising – SpaceX will have become the owner and operator of the world’s largest commercial satellite constellation. After tonight’s launch, SpaceX’s Starlink internet constellation will likely measure some 175 operational satellites strong less than eight months after the company began dedicated internal launches.
Assuming drone ship OCISLY safely returns Falcon 9 B1049 to port and including SpaceX’s successful November 2019 Starlink V1 L1 launch, the company now possesses two Falcon 9 boosters – B1048 and B1049 – that have successfully performed four separate orbital-class launches apiece. With two rockets in hand, SpaceX should be able to far more accurately determine just how well they’re standing up to the rigors of the latest reusability milestone, hopefully giving the company the data it needs to rapidly turn around one or both boosters for a fifth launch in the near future.
SpaceX has 20-24 Starlink launches planned for 2020, so the company will have a wealth of opportunities to push its fleet of reusable rockets to their limits, ranging from attempting nth booster reuses to testing and expanding the envelope of SpaceX’s nascent payload fairing reuse program.
In fact, fairing recovery ship GO Ms. Tree is perhaps just a few minutes away from her third successful fairing half catch – set to occur roughly 45 minutes after Falcon 9’s 9:19 pm EST liftoff. At the same time, Falcon 9’s upper stage is coasting in low Earth orbit (LEO) and preparing to ignite one more time to circularize its orbit and send SpaceX’s third batch of 60 Starlink satellites on their way. Stay tuned for updates later tonight!

Tesla hints at Starlink integration with recent patent
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.
The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”
Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.
Tesla has recently filed a US patent application on integrating RF transparent materials into the roof structure.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.
These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.
They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.
It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).
Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.
Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.
It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.
Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.
Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.
Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.
For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.
As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.
This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:
- Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
- Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
- Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
- Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
- Santa Mode – New graphics, trees, and a lock chime
- Light Show Update – Addition of Jingle Rush light show
- Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
- Navigation Improvements – Easier layout and setup
- Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
- Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
- Phone Left Behind Chime – Your car will now tell you if you left a phone inside
- Charge Limit Per Location – Set a charge limit for each location
- ISS Docking Simulator – New game
- Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition
Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…
— Wes (@wmorrill3) December 12, 2025
He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
