SpaceX Starship fires up three Raptor engines in prelude to high-altitude flight

Update: At 1:21am CDT (6:21 UTC) on October 20th, Starship SN8 ignited all three of its Raptors’ preburners, producing a spectacular fireball noticeably larger than the one produced during the rocket’s first October 19th preburner test. A mere two hours later, with no break in between, the steel rocket prototype fully ignited all three Raptor engines for the first time ever, likely producing thrust equivalent to ~90% of a nine engine Falcon 9 booster for a brief moment.

Crucially, aside from physically demonstrating Raptor’s multi-engine capabilities, Starship SN8 – already a first-of-a-kind prototype – completed and survived a static fire seemingly unscathed on its first attempt. If the data SpaceX gathers from the milestone is as good as the test appeared to be, the company could be just a few days away from installing Starship SN8’s recently-stacked nosecone, followed by a second triple-Raptor static fire test. If that second static fire goes well, SN8’s next task will be the first high-altitude Starship flight test.

Minutes after an adjacent highway was scheduled to reopen, SpaceX’s first high-altitude Starship prototype – serial number 8 – attempted what was likely the first multi-engine Raptor test ever.

At 6:01 am, October 19th, Starship SN8’s trio of Raptor engines were barely unleashed, producing a large fireball indicative of a ‘preburner’ ignition test. One of the most complex rocket engines ever developed, Raptor relies on a maximally efficient but temperamental “full-flow staged combustion” cycle (FFSC), a concise name for the many, many steps required to turn liquid propellant into thrust.

Adding additional difficulty, Raptor’s full-flow staged combustion necessitates ignition of gaseous oxygen and methane in the combustion chamber. Given that the Raptor-powered Starship spacecraft and Super Heavy booster exclusively use cryogenic liquid methane and oxygen, a major challenge posed by FFSC is the need to efficiently turn that ultra-cold propellant into hot gas almost instantaneously. This is where gas generators (or preburners) come in.

In a full-flow staged combustion engine, both oxidizer and fuel require their own separate turbopumps, which then require their own preburners to create the pressures needed to power those turbopumps and the gas the combustion chamber ignites to produce thrust. A step further, to enable high combustion chamber pressure like Raptor’s 300+ bar (~4400+ psi), those preburners need to produce gas at far higher pressures to account for energy losses as those gases wind their way through the engine’s plumbing.

As a result, preburners are possibly the single most stressed system in an engine like Raptor. Unsurprisingly, this has often lead SpaceX to separately test each engine’s preburners as a sort of partial static fire before the actual engine ignition test. This is the test Starship SN8 attempted in the early morning on October 19th, representing Raptor’s very first multi-engine ignition event.

Curiously, moments before preburner ignition, one of the three Raptor engines appeared to command an aggressive jet-like vent of liquid oxygen identical to a vent seen just a few hours prior during the first aborted preburner test. There’s thus a chance that only two of SN8’s three Raptor engines successfully started their preburners

Raptor is the first FFSC engine in the world to fly and – as far as the duration of lifetime testing and volume production goes – is almost certainly the most advanced of the three FFSC programs to graduate to static fire tests. In other words, given that SN8’s test campaign is the first time SpaceX has ever attempted to operate multiple adjacent Raptor engines at the same time, it’s not a huge surprise that progress towards the first three-engine static fire has been cautious and halting. Mirroring its Sunday/Monday testing, SpaceX will put Starship SN8 through another preburner and/or static fire attempt between 9pm and 6am CDT (UTC-5) on October 19/20. Even more 9-6 test windows are scheduled on October 21st and 22nd.

Meanwhile, not long after Starship SN8’s first preburner test was completed, SpaceX teams rolled a section of five steel rings inside a small windbreak and stacked the first truly functional nosecone – already outfitted with forward flaps – atop it. If Starship SN8 survives its first full triple-Raptor preburner and static fire tests, that new nosecone will likely be rolled to the launch pad for in-situ installation, topping off the rocket ahead of a spectacular 15 km (~50,000 ft) flight test.

Tesla announces major milestone at Gigafactory Shanghai

First deliveries started in December 2019, with the first units being given to employees. By the end of 2020, the plant was building cars at a run rate of around 150,000 vehicles annually.

Tesla has announced a major milestone at its Chinese manufacturing facility, Gigafactory Shanghai, confirming on Monday that it had built its four millionth vehicle.

Tesla Gigafactory Shanghai first started building cars back in October 2019 with Model 3 assembly, just ten months after the company broke ground on the plant’s 86-hectare piece of land.

First deliveries started in December 2019, with the first units being given to employees. By the end of 2020, the plant was building cars at a run rate of around 150,000 vehicles annually. Production continued to ramp up, and by September 2023, less than three years after it started building Tesla’s EVs, it had built its two millionth vehicle.

Fast forward to December 2025, and Tesla has confirmed that four million cars have rolled off of production lines at the plant, a major milestone in the six short years it has been active:

The capacity at Giga Shanghai is exceeding 950,000 vehicles per year, and this year, the company has delivered 675,000 cars through the first three quarters. It is also the only plant to manufacture the Model Y L, a longer wheel-based configuration of the all-electric crossover that is exclusive to the Chinese market.

Gigafactory Shanghai’s four million cars have not all stayed within the domestic market, either. For a considerable period, the factory was exporting a significant portion of its monthly production to Europe, helping Gigafactory Berlin supplement some Model Y volume and all of its Model 3 deliveries. This is due to the Berlin plant’s exclusive production plans for the Model 3.

The site is one of the most crucial in the company’s global plans, and Gigafactory Shanghai’s incredible pace, which has led to four million production units in just about six years. It’s fair to say that it won’t be long until we’re seeing Tesla celebrate the plant’s five millionth vehicle produced, which should happen sometime late next year or in early 2027, based on its current manufacturing pace.

The company also builds the Megapack on the property in an adjacent Megafactory.

Tesla is gamifying its Supercharging experience by offering a new “Charging Passport,” hoping to add a new layer to the ownership experience.

While it is not part of the Holiday Update, it is rolling out around the same time and offers a handful of cool new features.

Tesla’s Charging Passport will be available within the smartphone app and will give a yearly summary of your charging experience, helping encapsulate your travel for that year.

It will also include things like badges for special charging spots, among other metrics that will show all of the different places people have traveled to plug in for range.

Tesla will include the following metrics within the new Charging Passport option within the Tesla app:

  • Charging badges: Iconic charging badges for visiting places like the Tesla Diner, Oasis Supercharger, etc., Explorer Badge, and more
  • Total Unique Superchargers Visited
  • Total Charging Sessions
  • Total Miles Added during Charging Sessions
  • Top Charging Day
  • Longest Trip
  • Favorite Charging Locations

This will give people a unique way to see their travels throughout the year, and although it is not necessarily something that is needed or adds any genuine value, it is something that many owners will like to look back on. After all, things like Spotify Wrapped and Apple Music Replay have been a great way for people to see what music they listened to throughout the year.

This is essentially Tesla’s version of that.

With a handful of unique Superchargers already active, Tesla is also building some new ones, like a UFO-inspired location in New Mexico, near Roswell.

Tesla launches its coolest gift idea ever just a few weeks after it was announced

Tesla has launched its coolest gift idea ever, just a few weeks after it was announced.

Tesla is now giving owners the opportunity to gift Full Self-Driving for one month to friends or family through a new gifting program that was suggested to the company last month.

The program will enable people to send a fellow Tesla owner one month of the company’s semi-autonomous driving software, helping them to experience the Full Self-Driving suite and potentially help Tesla gain them as a subscriber of the program, or even an outright purchase.

Tesla has officially launched the program on its Shop. Sending one month of Full Self-Driving costs $112:

“Gift one month of Full Self-Driving (Supervised), which allows the vehicle to drive itself almost anywhere with minimal intervention. All sales are final. Can only be purchased and redeemed in the U.S. This gift card is valued at $112.00 and is intended to cover the price of one month of FSD (Supervised), including up to 13% sales tax. It is not guaranteed to cover the full monthly price if pricing or tax rates change. This gift card can be stored in Tesla Wallet and redeemed toward FSD (Supervised) or any other Tesla product or service that accepts gift card payments.”

Tesla has done a great job of expanding Full Self-Driving access over the past few years, especially by offering things like the Subscription program, free trials through referrals, and now this gift card program.

Gifting Full Self-Driving is another iteration of Tesla’s “butts in seats” strategy, which is its belief that it can flip consumers to its vehicles and products by simply letting people experience them.

There is also a reason behind pushing Full Self-Driving so hard, and it has to do with CEO Elon Musk’s compensation package. One tranche requires Musk to achieve a certain number of active paid Full Self-Driving subscriptions.

More people who try the suite are likely to pay for it over the long term.
