SpaceX’s third Falcon 9 launch in 31 hours aborted by “tiny helium leak”

Published

on

SpaceX’s third Falcon 9 launch in a little over 31 hours was called off seconds before liftoff after the rocket’s onboard computer detected what Elon Musk says was a “tiny helium leak.”

SpaceX takes “no risks with customer satellites,” per the CEO, so the company has stood down from its October 6th launch attempt to inspect the rocket, analyze data gathered from tonight’s attempt, and ensure everything is in order. Barring surprises, SpaceX will attempt to launch Intelsat’s Galaxy-33 and Galaxy-34 geostationary communications satellites at the next earliest opportunity, a 69-minute window that opens at 7:06 pm EDT (23:06 UTC) on Friday, October 7th.

The abort ends an opportunity SpaceX had to launch three Falcon rockets faster than ever before, but the company was still able to crush a different (internal) record with two Falcon 9 launches in seven hours on October 5th. Thanks to its relentless pursuit of ever-higher launch cadences, SpaceX will likely have many opportunities to break its record of three launches in ~36 hours over the next several months.

Intelsat’s Galaxy-33/Galaxy-34 (G33/G34) mission would have been SpaceX’s third Falcon 9 launch in 31 hours and 20 minutes following the successful October 5th launches of Crew-5 (carrying four astronauts) at 12:00 pm EDT and Starlink 4-29 (deploying 52 Starlink satellites) at 7:10 pm EDT. The hat-trick record for a non-SpaceX vehicle appears to have been previously held by the Soviet R-7 rocket family, which completed three launches in 40 hours in March 1978.

SpaceX broke that record in June 2022 when it launched Starlink 4-19, SARah-1, and Globalstar FM15 a little over 36 hours apart. It will now have to wait for another opportunity to break its own record, though it likely won’t be too long as the company continues to target 60 launches in 2022 and “up to” 100 launches in 2023.

According to a SpaceX launch controller, Falcon 9’s first ill-fated Galaxy-33/Galaxy-34 launch attempt was aborted automatically when the rocket’s flight computer “identified higher than expected cryo helium decay.” SpaceX’s Falcon rockets burn a combination of cryogenic liquid oxygen and chilled rocket-grade kerosene (RP-1), but they carry composite overwrapped pressure vessels (COPVs) filled with high-pressure helium gas to keep their propellant tanks pressurized as they’re drained. If SpaceX’s much larger Starship rocket shares some similarities, the company may also use a system of “helium injection” [PDF] inside Falcon 9 to keep its cryogenic oxygen and chilled kerosene as cold as possible. Musk later simplified the cause of the abort to a “tiny helium leak,” but the location of the leak (inside or outside of the rocket) was not specified.

Two hours before that, the Crew Dragon spacecraft SpaceX launched the day prior successfully docked with the International Space Station (ISS), delivering its ‘payload’ of four professional astronauts to the orbital outpost. One of those passengers is Russian cosmonaut Anna Kikina, marking the first time an American spacecraft has ferried a Russian to the ISS in almost 20 years. That milestone has unfortunately been muddied and overshadowed by the country’s illegal, genocidal, and increasingly suicidal invasion of Ukraine.

Crew-5 is the seventh Crew Dragon to successfully transport astronauts to the ISS and SpaceX’s eighth crewed launch overall since May 2020. Flying for the second time, Crew Dragon capsule C210 docked on its first try after a smooth 29-hour rendezvous. About a week from now, another crew of four astronauts will board a different Crew Dragon spacecraft and return to Earth, handing off the ISS to Crew-5 and ending SpaceX and NASA’s Crew-4 mission.

SpaceX is scheduled to launch at least one more batch of astronauts for NASA in March or April 2023, meaning that the company is expected to singlehandedly ensure NASA access to the ISS for almost three full years. At the start of the Commercial Crew Program and for most of its development, NASA intended for partners SpaceX and Boeing to alternate, but Boeing’s Starliner spacecraft is years behind schedule.

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.
