SpaceX schedules Starship’s first triple-Raptor static fire test

A photo posted by CEO Elon Musk confirms that SpaceX has successfully installed three functional Raptors on Starship SN8 just hours before road closure notices revealed the company’s first triple-engine static fire schedule.

Technically, it’s incorrect to say that Starship serial number 8 (SN8) is the first prototype to receive three Raptor engines. Back in late-September 2019, in the lead-up to Musk’s promised Starship update event, the company installed three Raptors on the first full-scale prototype, known as Starship Mk1. The engines were only installed as an apparent fit test or even a photo opportunity, however – evidenced by the fact that they weren’t actually plumbed to the Starship’s propellant tanks.

Even then, in September 2019, Starship Mk1 was far from ready to make use of Raptor engines and was more than a month away from attempting its first pressure and cryogenic proof tests – tests it quickly failed. As such, Starship SN8 – having more or less successfully passed its ‘cryo proof’ by October 9th – is undoubtedly the first ship to have a shot at igniting multiple Raptor engines at once.

Curiously, SpaceX remained quiet for several days after Starship SN8 passed its first big test. Whereas with past Starship prototypes SpaceX has often filed test plans (appearing in the form of road closures) even before the current phase of testing is complete, the company waited until Tuesday, October 14th to file closure notices for “SN8 static fire” testing.

Same as Starships SN4, SN5, and SN6, all of which successfully graduated from cryo proof to static fire testing (and even flight tests for the latter two), SpaceX began Starship SN8’s test campaign with a cryo proof. It took three days and at least as many attempts but SN8 ultimately “passed cryo proof” according to Elon Musk, likely meaning that the ship reached sustained pressures of 7.5 bar (~110 psi) or more.

Cryo proof complete, SpaceX installed Starship SN8’s engines – the first time multiple Raptors have been fully integrated with a rocket or test stand – in preparation for another Raptor first: multi-engine static fires. While modern computation fluid dynamics (CFD) and modeling mean that the great unknowns of rocket propulsion are rarely as opaque as they used to be, the first test of multiple powerful engines in close proximity is still a guaranteed recipe for surprises.

Thanks to expertise hard-won from nearly 100 Falcon 9 and Falcon Heavy launches, SpaceX is likely the world’s foremost expert in the challenges and dynamics of the proximity operation of more than two rocket engines. At the same time, though, Raptor is a dramatically different engine than Merlin 1D and while Starship will only have six engines at most, those six engines will produce thrust equivalent to almost two entire Falcon 9 boosters.

In other words, even with a (relatively) simple three-Raptor static fire, SpaceX will be treading new ground and will almost certainly end up learning one or several things about Raptor’s design and operation. More likely than not, SpaceX will begin Starship SN8’s static fire test campaign with a wet dress rehearsal (like a cryo proof but with real liquid methane and oxygen propellant) and transition into a Raptor spin prime (turbopump spin-up) or preburner test (a turbopump spin-up but with partial combustion) if the WDR goes smoothly. If all three Raptor engines appear healthy, SpaceX may recycle and attempt the first static fire just an hour or two later.

Starship SN8’s triple-Raptor static fire test window opened at 9pm CDT on October 14th and closes at 6am on the 15th, with an identical 9pm-6am backup on the 15th and another window from 8am to 4:30pm on the 16th. LabPadre (below) will continue to offer 24/7 views of Starship, including any static fire testing, while NASASpaceflight.com will likely provide live coverage once testing begins in earnest.

Tesla plans for new 300+ stall Supercharger with a special surprise for Semi

Published

Tesla is planning for a new 300+ stall Supercharger station that will be an expansion of an existing facility, and the company is planning to add a surprise for the Semi.

The Firebaugh, California Supercharger is currently 72 Superchargers, but Tesla filed for an expansion that will add 232 additional plugs for passenger vehicles, and it also plans to add 16 Semichargers.

This will be the biggest Supercharger station Tesla will have to date, just months after it finished the Supercharger Oasis in Lost Hills, California, which has 168 stalls. This will have 304 total Supercharger stalls, and then the additional 16 Megachargers.

The Firebaugh Supercharger is located on I-5, which is a major reason for why Tesla has chosen the location for additional Megacharger plug-ins, as Tesla Semi Program Manager Dan Priestley said on X earlier today.

The project was revealed by MarcoRP, a Supercharger tracker.

The expansion is a massive signal for charging demand, especially as Tesla’s Superchargers are opened to numerous automakers and are no longer exclusive to the company’s EVs. Additionally, the installation of Megachargers is a good sign to come for the Tesla Semi program, which aims to truly ramp up this year.

Tesla plans to launch production of the Semi later this year.

It could also mean Tesla is going to expand its footprint of large-scale Supercharger projects in the coming years, which would be a big boost as EV adoption continues to soar in the United States.

Tesla makes two big interior changes to several Model Y vehicles

Tesla has made two big interior changes to several Model Y vehicles in its lineup, and the changes come just as the new model year begins production.

Last year, Tesla launched the Model Y Standard, which separated the previous models into the “Premium” category. The Standard vehicles lack several features, including more premium interior materials, acoustic-lined glass, and storage.

@teslarati There are some BIG differences between the Tesla Model Y Standard and Tesla Model Y Premium #tesla #teslamodely ♬ Sia – Xeptemper

The Model Y “Premium” trims are now getting several new upgrades, which come after the company launched a seven-seat configuration of the vehicle last night in the North American market for an upcharge of $2,500.

The new Model Y seven-seat configuration did not come with just an additional row of seating; it also came with a slew of other goodies that now come standard and were previously only available on the Model Y Performance, which was launched late last year.

All Black Headliner

The new Tesla Model Y Premium trims will now come standard with a black headliner, something that many owners have been requesting for some time.

The previous grey headliner and trim within the vehicle is now gone; it will be all black on all of the Premium trims from here on out, a welcome change:

Larger and Higher Resolution Center Touchscreen

The center touchscreen in the new Model Y Premium configuration is now larger and has a higher resolution than the previous version.

In last year’s Model Y configurations (apart from the Performance), the center touchscreen was 15.4″. Now, Tesla has decided to go with the 16″ version across all Premium trims, which is a nice step up. It was nice to see this in the Performance, but it is really great to see Tesla include this in the Model Y’s more Premium trim levels.

Tesla Model Y Seven Seater

Tesla launched the latest iteration of the seven-seater for the Model Y on Monday night. Traditionally, the Model Y seats five passengers in total, but there were calls for a more spacious version several years ago.

Tesla released it, but it was extremely tight in the back, basically reserving those back seats for only small people or children.

The new configuration looks to be slightly more spacious in the third row, but not as much space as most would require or want. Instead,

Starlink’s low-Earth orbit satellites are expected to provide significantly higher bandwidth and lower latency than traditional in-flight Wi-Fi, which should enable streaming, online work, and other data-intensive applications for passengers during flights.

Starlink-powered internet is expected to be available on the first commercial flights as early as the second half of 2026. The rollout will continue through the decade, with the entire Lufthansa Group fleet scheduled to be fully equipped with Starlink by 2029. Once complete, no other European airline group will operate more Starlink-connected aircraft.
