SpaceX's latest reusable rocket booster returns to port to prepare for next launch
The first new Falcon 9 booster SpaceX has debuted in almost half a year safely returned to port after a successful first launch and landing, setting the reusable rocket up to fly again in the near future.
On December 5th, after a brief 24-hour weather-related delay, new Falcon 9 booster B1059 lifted off on its first mission, successfully sending flight-proven Cargo Dragon capsule C106 to orbit for the third time before the rocket slowed itself down and landed on drone ship Of Course I Still Love You (OCISLY).
Over the next three or so days, the SpaceX spacecraft gradually boosted and tweaked its orbit to rendezvous with the International Space Station (ISS) and ultimately began its ISS approach and berthing maneuvers on December 8th. A few hours after that, ISS astronauts successfully ‘caught’ Dragon with the station’s massive robotic arm and gently berthed the spacecraft at an open port.
Less than a day before Dragon arrived at the ISS, effectively completing the majority of its CRS-19 resupply mission, the Falcon 9 booster that launched the spacecraft wrapped up a successful launch debut by returning to a different kind of port. Falcon 9 B1059 returned to Port Canaveral aboard drone ship OCISLY on the morning of December 7th and was quickly released from SpaceX’s robotic Octagrabber robot and lifted onto dry land.
SpaceX’s 13th successful Falcon booster recovery of 2019, B1059’s return to port also marked the first flight of a new Falcon booster since June 25th – almost half a year prior. By the numbers, B1059 was subjected to a relatively gentle atmospheric reentry prior to landing aboard OCISLY, meaning that it should be easier for SpaceX technicians and engineers to recertify the rocket and turn it around for its next launch.
Depending on where SpaceX and NASA stand, the booster’s second launch could happen anywhere from 2-4 months from now. Given that NASA currently allows SpaceX to fly reused boosters on NASA missions only if those boosters have exclusively flown NASA missions in the past, B1059 could end up supporting CRS-20, SpaceX’s next and last Cargo Dragon (Dragon 1) mission. CRS-20 is scheduled to launch no earlier than (NET) March 2020 and will be followed by the launch debut of Crew Dragon’s Cargo variant as soon as August 2020, another possibility for B1059’s second flight.
However, if SpaceX follows in the footsteps of CRS-19 and instead prioritizes rapid customer launches over saving a given gently-used booster for another NASA mission, B1059 could be a prime candidate for an extremely rapid turnaround, perhaps supporting an internal SpaceX Starlink launch or any number of other customer satellite launches in early 2020. On the other hand, it’s possible that B1059 suffered an unusually damaging reentry for unknown reasons, although it’s hard to judge from photos and a layperson perspective alone.
From a few angles, it almost appears as if B1059’s white paint was completely burned or scoured off in places, leaving a distinct transition between the edge of remaining paint and the booster’s distinctly metallic-looking skin underneath it. Falcon 9’s main structure is almost entirely built out of a high-performance aluminum-lithium alloy and sealed (and partially shielded) with a multilayer temperature and corrosion-resistant coating. If B1059’s tank coating was indeed partially burned off during reentry, SpaceX will almost certainly have to perform uniquely detailed inspections to verify the structural integrity of its propellant tanks, perhaps preventing a rapid (record-breaking) turnaround.
Either way, Falcon 9 B1059 was quickly lifted off of OCISLY and technicians even managed to retract all four of the new booster’s deployable landing legs, a great sign that SpaceX is confident that the booster is in fine shape. With the addition of B1059, SpaceX’s fleet of flight-proven, flightworthy Falcon 9 boosters is now eight strong – nine if Crew Dragon’s unflown Demo-2 booster is included. That fleet will continue to grow as SpaceX gradually introduces new boosters for increasingly rare military and NASA missions.

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.
