SpaceX’s next Starship launch still waiting on a successful Raptor test

Published

Several days after the last test attempt, SpaceX’s next Starship launch remains delayed pending a successful static fire of the prototype’s three Raptor engines.

Delivered from SpaceX’s Boca Chica, Texas rocket factory to nearby launch and test facilities on December 22nd, less than two weeks after Starship serial number 8’s (SN8) high-altitude launch debut, successor Starship SN9 completed its first crucial test on December 29th. Known as a cryogenic proof test, SN9 was loaded either partially or fully with a large volume of liquid nitrogen to simulate the thermal stresses caused by liquid methane and oxygen propellant and ensure that pad systems and the rocket’s plethora of valves, pipes, and avionics were working as expected.

Cryoproof more or less completed on schedule, SN9’s follow-up static fire test continued in a similarly smooth fashion, with the first attempt once again falling within a planned three-day window – albeit on January 6th, the last of those three days. Near the end of the 8 am to 5 pm window, Starship SN9 ignited all three preinstalled Raptor engines but NASASpaceflight.com ultimately revealed that the test had been shorter than SpaceX expected.

Relative to all previous Starship testing, even ignoring the facts that a handling error damaged SN9 just one month ago and that the rocket is only the second prototype to have a full nose section installed and plumbed, SN9’s test campaign has been smooth. Despite the unique hurdles SN9 faced, the Starship completed a cryoproof and a static fire on its first respective day of attempts. Minor slips along the way – including recent static fire re-do delays – simply serve as a reminder that the Starship program and its prototypes have yet to reach operational maturity.

Why SN9’s first static fire ended prematurely is unclear and could have been caused by just about anything. The fact that all three Raptors shut down early points a finger to something other than the engines themselves and the clean abort SN9 seemingly commanded points to a relatively minor issue as far as rocket prototypes go.

Two days later, SpaceX tried again but had even less luck, seemingly never making it more than 10-20 minutes into a usual 40-60 minute static fire test flow in several consecutive attempts. Due to an apparent agreement with Cameron County to avoid road closures on the weekend, Starship SN9’s next shot at a second static fire was delayed three days to Monday, January 11th. Possibly due to high winds and generally unfavorable weather, Monday’s static fire attempt was called off before the window opened.

Later that day, SpaceX delivered notices confirming that the next SN9 static fire attempt was now scheduled no earlier than (NET) 8 am to 5 pm CST (UTC-6) on Tuesday, January 12th. Whether SN9 actually pulls off a full-duration static fire, weather forecasts remain unfavorable for a low-velocity, high-altitude launch. Cancelled FAA Temporary Flight Restrictions (TFRs) more or less confirmed SpaceX’s agreement with those forecasts, leaving Starship SN9’s 12.5 km (~7.8 mi) launch debut scheduled no earlier than Friday, January 15th or Saturday, January 16th.

Tesla Robotaxi has already surpassed Waymo in one extremely important key metric: size of service area.

Tesla just expanded its service area in Austin on Monday morning, pushing the boundaries of its Robotaxi fleet in an interesting fashion with new capabilities to the north. Yes, we know what it looks like:

The expansion doubled Tesla Robotaxi’s potential travel locations, which now include the University of Texas at Austin, a school with over 53,000 students.

The doubling of the service area by Tesla has already made its travel area larger than Waymo’s, which launched driverless rides in October 2024. It became available to the public in March 2025.

According to Grok, the AI agent on X, Tesla Robotaxi’s current service area spans 42 square miles, which is five square miles larger than Waymo’s service area of 37 square miles.

The service area is one of the most important metrics in determining how much progress a self-driving ride-hailing service is making. Safety is the priority of any company operating a ride-hailing network, especially ones that are making it a point to use autonomy to deploy it.

However, these companies are essentially racing for a larger piece of the city or cities they are in. Waymo has expanded to several different regions around the United States, including Arizona and Los Angeles.

Tesla is attempting to do the same in the coming months as it has already filed paperwork in both California and Arizona to deploy its Robotaxi fleet in states across the U.S.

As the platform continues to show more prowess and accuracy in its operation, Tesla will begin to expand to new areas, eventually aiming for a global rollout of its self-driving service.

The first of over 300 Tesla Megapacks have arrived to the site of a massive battery energy storage system (BESS) being built in Australia, dubbed the Stanwell Battery Project after a coal plant it’s set to replace.

In a press release last week, the Stanwell Battery Project announced that the first Tesla Megapack 2XL units had arrived to the site, which is located outside of Rockhampton in Queensland, Australia. The project will eventually feature 324 Megapack units, set to arrive in the coming months, in order to support the 300MW/1,200MWh battery project.

“The Stanwell Battery is part of the diversification of our portfolio, to include cleaner and more flexible energy solutions,” said Angie Zahra, Stanwell Central Generation General Manager. “It is just one part of the 800 MW of battery energy storage capacity we have in our pipeline.

“Capable of discharging 300 MW of energy for up to four hours (1,200 MWh), our mega battery will be one of the largest in Queensland.”

The state is working with government-owned company Yurika to facilitate construction, and the process is expected to create roughly 80 jobs. The project is expected to come fully online in May 2027, with initial commissioning of the Megapacks aiming for November 2025.

The Stanwell Battery is set to replace the nearby Stanwell coal generation plant, which the government is planning to wind down starting in 2026 as part of efforts to reach an 80 percent renewable energy generation ratio by 2035. Meanwhile, the government is also set to begin winding down the Tarong and Callide coal plants, while several other Megapack projects are being built or coming online. o ya

Tesla currently has two Megapack production facilities, located in Lathrop, California, in the U.S. and another that came online earlier this year in Shanghai, China. The Shanghai Megafactory shipped its first units to Australia in March, while both factories are expected to be capable of producing 10,000 Megapack units per year upon reaching volume production.

Tesla has finally completed the construction of its highly anticipated Diner, Drive-in, and Supercharger in Los Angeles, and recent photos of the interior’s “retro-futuristic” style are making their way around the internet.

X user Brad Goldberg shared photos from the Tesla Diner site last Tuesday, depicting some of the Supercharger stalls, indoor and outdoor seating areas, multiple neon lights, and even an Optimus robot. Goldberg also noted that there had been a “flurry of activity on site” while he was snapping the photos last week, suggesting that the restaurant location could be getting close to opening.

The Tesla Diner also served one of its first internal customers in the past few days, as Elon Musk posted on X on early Monday morning that he had just finished up eating a meal at the site:

I just had dinner at the retro-futuristic Tesla diner and Supercharger.

Team did great work making it one of the coolest spots in LA!

The photos also show that the site is pretty much done, with some of them even showing vehicles charging at the charging stalls.

When will the Tesla Diner open to external customers?

While it’s still not open to external customers yet, the news again suggests that the company could be close to an official opening date. Tesla first broke ground on the Diner in September 2023, after receiving a wave of building permit approvals throughout that year. Teslarati also covered much of the construction progress throughout last year, including when crews installed the first and second drive-in screens.

Located at 7001 West Santa Monica Boulevard, the idea was first discussed in 2018 by Musk and a few others on Twitter, featuring 1950s rock and roll, waiters on roller skates, and drive-in movie theater screens playing clips from some of history’s best movies. Notably, the photos of the front doors also show that the site will be open 24 hours a day, 7 days a week, whenever it does end up opening.
