SpaceX drone ship heads to sea for record-breaking Starlink launch

SpaceX’s newest drone ship is on its way out into the Atlantic Ocean for a Starlink mission that will break the company’s record for annual launch cadence.

Somewhat confusing known as Starlink Shell 4 Launch 3 or Starlink 4-3, the batch of 53 laser-linked V1.5 satellites is scheduled to fly before Starlink 4-2 for unknown reasons and at the same time as Starlink 2-3 is scheduled to fly before Starlink 2-2 on the West Coast. Regardless of the seemingly unstable launch order, perhaps related to the recent introduction of Starlink’s new V1.5 satellite design, drone ship A Shortfall of Gravitas’ (ASOG) November 27th Port Canaveral confirms that SpaceX is more or less on track to launch Starlink 4-3 no earlier than (NET) 6:20 pm EST (23:20 UTC) on Wednesday, December 1st.

In a bit of a return to stride after launching 20 times in the first six months but only three times in the entire third quarter of 2021, Starlink 4-3 is currently the first of four or even five SpaceX launches scheduled in the last month of the year. Nevertheless, if Starlink 4-3 is successful, it will also set SpaceX up to cross a milestone unprecedented in the history of satellite launches.

Specifically, Starlink 4-3 is SpaceX’s 16th dedicated Starlink launch of 2021 and will mark 951 Starlink satellites safely delivered to orbit since January 20th. If, as CEO Elon Musk has telegraphed is the plan, SpaceX intends to complete one more dedicated Starlink launch in December (either Starlink 2-2 or 2-3), the company could round out 2021 having launched more than a thousand satellites in a single year.

Thanks to Starlink, 2020 was the first year in history in which more than a thousand satellites (technically 1283) were launched into orbit. Now, in 2021, there’s a good chance that SpaceX Starlink launches alone will account for more than a thousand satellites launched in one year. Altogether, SpaceX will likely end the year having singlehandedly launched a total of more than 1240 satellites in 2021 – and despite only completing 3-4 Starlink launches in the last seven months of the year compared to 13 in the first five months.

For SpaceX and Starlink, that’s great news. In March and November 2018, the FCC approved two SpaceX applications to launch and operate constellations of ~4400 and ~7500 Starlink satellites – a total of around 11,900 satellites. To avoid having its licenses revoked, SpaceX – like all other FCC constellation applicants – is required to launch half of its licensed constellation within six years of its license receipts and full constellation within nine years. For SpaceX, that means it has to launch at least ~2200 satellites operating around 550 km (340 mi) and ~3750 satellites operating around 350 km (~220 mi) by March and November 2024, respectively.

With a bit less than 1700 Starlink satellites currently functioning in orbit, even if SpaceX merely repeats its 2021 cadence, it will be on track to outright finish Starlink’s first 4400-satellite phase by mid-2024 and should easily cross the halfway mark by mid-2022 – years ahead of schedule for both. However, simultaneously hitting Starlink’s very low Earth orbit (VLEO) deployment milestones will still be a massive challenge. Given that SpaceX has yet to launch a single VLEO Starlink spacecraft three years after license approval, it now has less than three years to launch ~3750 VLEO satellites on top of at least 500 more LEO satellites.

If SpaceX can replicate its H1 2021 Starlink launch cadence throughout 2022, completing at least 26 launches in 52 weeks, it may actually have a shot at pulling off a cadence close to what is needed to meet its FCC deployment requirements (an average of 1400 satellites per year for the next three years). If SpaceX simply aims for the average annual numbers needed to complete the full ~11,900-satellite Starlink constellation by November 2027, it will need to launch around 1800-2000 satellites per year – equivalent to 35-40 Falcon 9 rockets.

Tesla Model X lost 400 pounds thanks to these changes

Published

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.
