SpaceX has at long last transported its fifth full-scale Starship prototype to a nearby launch pad, kicking off a week of busy pre-test preparations while the sixth rocket is already nipping at its heels.

Starship SN5’s move to the pad ends the longest gap between full-scale prototype testing since Starship Mk1 was destroyed in November 2019, a partially-expected failure that began a more than three-month period of infrastructure upgrades. The first upgraded Starship (SN1) rolled to the pad on February 25th, followed by SN3 on March 29th and SN4 on April 23rd, indicative of a fairly consistent monthly cadence of Starship production (and destruction).

Almost exactly two months after its predecessor headed from the factory to SpaceX’s Boca Chica, Texas launch facilities, Starship SN5 has taken its place on a brand new launch mount. The cause of that month-long delay is fairly simple. When Starship SN4 exploded on May 29th, it damaged the existing launch mount and some additional ground support equipment (GSE), forcing SpaceX to scrap the destroyed mount and build a new one from scratch. In a matter of weeks, SpaceX’s crack team of pad engineers and technicians have done exactly that.

While, judging from several sets of canceled road closure days, the new mount wasn’t built quite as quickly as someone high up in SpaceX would have hoped, the speed of the recovery from SN4’s destructive demise is still extremely impressive. For full-scale operations, SpaceX needs a strong metal structure capable of providing a Starship prototype the propellant, power, and communications links it needs to perform tests, as well as standing up to the weight of a full-loaded Starship (>1000 metric tons) and preventing the rocket from flying away during static Raptor engine tests. Additionally, the launch mount will eventually need to survive the fury of one and even three Raptor engines once Starships graduated to flight testing.

As of June 3rd, the replacement launch mount was partially-completed steel skeleton.

Barely two weeks later, SpaceX had flipped that skeleton, installed it on the actual launch mount table, finished all structural work, installed a conical frame to enable hydraulic ram testing to simulate Raptor engine thrust, and outfitted the mount with a wide variety of complex plumbing, wiring, and fixtures. The current design is about as simple as it can get but is still relatively complicated, with a wide range of systems that must work perfectly together throughout an equally wide range of temperatures and other stressful conditions.

Starship SN5’s installation on that replacement mount serves as a final confirmation that the new structure is more or less complete. Now SpaceX will be faced with the different challenges of christening the new launch mount and ensuring that it’s functioning as planned at the same time as Starship SN5 is attempting to do the same thing. The company also appears to have taken the previous launch mount’s demise as an opportunity to implement some minor design changes, all of which will also need to be tested and verified.

Delays are quite likely but Starship SN5 is currently scheduled to kick off its first test campaign as early as June 29th. SpaceX will likely begin with an ambient pressure test to check for leaks, followed by a cryogenic proof test with liquid nitrogen to confirm that SN5 performs as expected while subjected to the ultra-cold temperatures its liquid methane and oxygen propellant will be kept at. SN5 would then move into wet dress rehearsals (WDR) with live propellant and one or several static fires with a single Raptor engine. Finally, if that complex series of tests goes a little bit better than it did with SN4, Starship SN5 will become the first full-scale prototype to attempt controlled flight, hopping to at least 150m (~500 ft).

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.
