SpaceX aims for a burst of December launches despite recent delays
Originally scheduled to launch on December 4, SpaceX’s thirteenth resupply mission to the International Space Station (ISS) has been pushed back to no earlier than Friday, December 15 after routine preflight checks identified potential contaminants in the Falcon 9 launch vehicle’s upper stage fuel lines.
The past six weeks have been something of an outlier in an otherwise relentless series of 2017 launches for SpaceX. In early November, defects in payload fairings were discovered at the company’s Hawthorne, CA factory and quickly traced to the Zuma mission’s fairing, at that point already vertical and prepared to launch from Kennedy Space Center. SpaceX chose to pause its launch indefinitely as it investigated the fairings already delivered to its several launch pads and began the process of either repairing or replacing those impacted. The CRS-13 Cargo Dragon mission soon took precedent as Zuma remained on hold.

Although CRS-13 does not require a payload fairing and was thus unaffected by SpaceX’s ongoing investigation, the mission was scheduled to be launched from Launch Complex-40, essentially a new pad after ten months of extensive repairs and upgrades. This translated into a few days of additional delays as the SpaceX launch crew thoroughly tested the pad’s new systems and pushed towards static fire of the flight proven Falcon 9 booster, successfully completed on December 6 after an additional handful of days of pad-related delays. This pushed the launch date from the 4th to the 8th, then the 12th and the 13th to accommodate further limited testing in order to ensure pad readiness. However, routine tests revealed a possible fuel line contamination in Falcon 9’s second stage, and SpaceX delayed the mission an additional 48 hours to resolve the problem. CRS-13 is now aiming for launch no earlier than 7:35am/10:35am PST/EST on December 15, but the window is instantaneous and any additional delays would push the launch into late December, at which point Cape Canaveral Air Force Station returns to operational status with the conclusion of winter holidays.
Although LC-40 suffered through its own teething period of bugs and testing while returning to life, there is a certain irony in the fact that a bug in the only wholly new component of CRS-13’s Falcon 9 rocket has been the most recent cause of delay; both the Falcon 9 booster and Cargo Dragon capsule are refurbished, flight-proven hardware, although both the trunk and heat shield of the Dragon were likely replaced with new components. There is something to be said about the logical nature of truly “flight-proven” hardware being more trustworthy than completely new alternatives, but it is far more likely that the upper stage contamination can be largely traced back to the new pad hardware.

Although Teslarati’s launch photographer Tom Cross has been battered about by Zuma and CRS-13 delays, SpaceX has demonstrated an admirable level of patience and caution, risking significant delays to their launch manifest in order to best ensure the safety and reliability of their launch services. While delays are painful in the spaceflight fan business, they are impermanent and secondary to safety and success. SpaceX will undoubtedly return to their regular programming in no time at all, with the West-coast launch of Iridium-4 and first pad rollout of Falcon Heavy up next on the docket. Stay tuned!

Tesla Model X lost 400 pounds thanks to these changes
The Tesla Model X has always been one of the company’s most loved vehicles, despite its low sales figures, which can be attributed to its high price tag.
However, the Model X has been a signature item on Tesla’s menu of cars, most notably recognized by its Falcon Wing Doors, which are aware of its surroundings and open according to what’s around it.
But recent improvements to the Model X were looking slim to none, but it appears most of the fixes actually happened under the body, at least according to Tesla’s Vice President of Powertrain, Lars Moravy.
In a recent interview with Car and Driver, Moravy detailed all of the changes to the 2026 iteration of the vehicle, which was about 400 pounds lighter than it was originally. The biggest change is a modification with the rear motor, switching from an induction-type motor to a permanent-magnet design and optimizing the half-shafts, which shed about 100 pounds.
Tesla also got “almost 80 pounds out of the interior bits and pieces,” which “included making parts thinner, different manufacturing process choices, and incorporating airbag-deployment requirements into the headliner fabric,” the report said.
Additionally, the standard five-passenger, bench seat configuration saved 50 pounds by ditching pedestal mounting. This also helped with practicality, as it helped the seat fold flat. Engineers at Tesla also saved 44 pounds from the high-voltage wiring through optimizing the wiring from the charge-port DC/DC converter and switching from copper to aluminum wiring.

Tesla also simplified the cooling system by reducing the number of radiators. It also incorporated Nürburgring cooling requirements for the Plaid variant, which saved nearly 30 pounds.
Many Tesla fans will be familiar with the megacastings, manufactured in-house by presses from IDRA, which also saves more than 20 pounds and boosts torsional stiffness by around 10 percent. Tweaks to the suspension also saved 10 pounds.
People were truly disappointed with what Tesla did with the Model S and Model X, arguing that the cars needed a more severe exterior overhaul, which might be true. However, Tesla really did a lot to reduce the weight of the vehicle, which helps increase range and efficiency. According to Grok, every 200 pounds removed adds between 7 and 15 percent to range estimations.
This makes sense considering the range estimations both increased by 7 percent from the Model X’s 2025 configuration to the 2026 builds. Range increased on the All-Wheel-Drive trim from 329 miles to 352 miles, while the Plaid went from 314 miles to 335 miles.

Tesla launches its new branded Supercharger for Business with first active station
Tesla has officially launched its first branded Supercharger just months after initiating a new program that allows third-party companies to brand their own charging piles.
The site opened in Land O’ Lakes, Florida, and features eight V4 Supercharging stalls offering up to 325 kW of charging speed. It appears it was purchased by a company called Suncoast Credit Union. This particular branch is located Northeast of Tampa, which is on the Gulf of Mexico.
It features graphics of Florida animals, like alligators:

Tesla launched this program back in September, and it basically was a way to expand its Supercharger presence and also allow companies to pay for the infrastructure. Tesla maintains it. When it announced the “Supercharger for Business,” it said:
“Purchase and install Superchargers at your business. Superchargers are compatible with all electric vehicles, bringing EV drivers to your business by offering convenient, reliable charging.”
The program does a few things. Initially, it expands EV charging infrastructure and makes charging solutions more readily available for drivers. It can also attract people to those businesses specifically.

The chargers can also be branded with any logo that the business chooses, which makes them more personalized and also acts as an advertisement.
The best part is that the customers do not have to maintain anything about the Supercharger. Tesla still takes care of it and resolves any issues:
“We treat your site like we treat our sites. By providing you with a full-service package that includes network operations, preventative maintenance, and driver support, we’re able to guarantee 97% uptime–the highest in the industry.”
It appears the Superchargers will also appear within the in-car nav during routing, so they’ll be publicly available to anyone who needs to use them. They are still available to all EVs that have worked with Tesla to utilize its infrastructure, and they are not restricted to people who are only visiting the business.

Tesla reveals its Cybertruck light bar installation fix
Tesla has revealed its Cybertruck light bar installation fix after a recall exposed a serious issue with the accessory.
Tesla and the National Highway Traffic Safety Administration (NHTSA) initiated a recall of 6,197 Cybertrucks back in October to resolve an issue with the Cybertruck light bar accessory. It was an issue with the adhesive that was provided by a Romanian company called Hella Romania S.R.L.
Tesla recalls 6,197 Cybertrucks for light bar adhesive issue
The issue was with the primer quality, as the recall report from the NHTSA had stated the light bar had “inadvertently attached to the windshield using the incorrect surface primer.”
Instead of trying to adhere the light bar to the Cybertruck with an adhesive, Tesla is now going to attach it with a bracketing system, which will physically mount it to the vehicle instead of relying on adhesive strips or glue.
Tesla outlines this in its new Service Bulletin, labeled SB-25-90-001, (spotted by Not a Tesla App) where it shows the light bar will be remounted more securely:
The entire process will take a few hours, but it can be completed by the Mobile Service techs, so if you have a Cybertruck that needs a light bar adjustment, it can be done without taking the vehicle to the Service Center for repair.
However, the repair will only happen if there is no delamination or damage present; then Tesla could “retrofit the service-installed optional off-road light bar accessory with a positive mechanical attachment.”
The company said it would repair the light bar at no charge to customers. The light bar issue was one that did not result in any accidents or injuries, according to the NHTSA’s report.
This was the third recall on Cybertruck this year, as one was highlighted in March for exterior trim panels detaching during operation. Another had to do with front parking lights being too bright, which was fixed with an Over-the-Air update last month.
