SpaceX’s thin-skinned Starship ‘test tank’ passes first trial
CEO Elon Musk says that a new thin-skinned Starship ‘test tank’ just passed its first trial, taking advantage of delays to Starship SN9’s planned high-altitude launch debut.
Delayed by a lack of FAA approval for unknown reasons, Starship SN9’s 12.5-kilometer (7.8 mi) launch debut (virtually identical to SN8’s 12.5 km launch last month) is in limbo pending an “FAA review” according to Musk. SpaceX thus found itself with at least 24 hours of guaranteed inactivity for Starship SN9, time the company rapidly chose to fill with crane transportation and, more importantly, the first Starship ‘test tank’ stress test in months.
Known as Starship SN7.2, SpaceX’s latest ‘test tank’ is the third to carry the SN7 moniker and appears to have been built primarily to test refinements to the rocket’s structural design. Following test tanks SN7.0 and SN7.1, both used to qualify the use of a new steel alloy on an otherwise unchanged design, SN7.2 – likely built out of the same alloy – is instead focused on determining if SpaceX can begin trimming the margins of an increasingly mature technology.
Curiously, SN7.2 is a sort of fusion of its predecessors: combining the stout stature of SN7.0 with SN7.1’s use of an aft thrust dome, but without SN7.1’s Starship-style skirt (the three rings at its bottom). Welded directly to its black test stand, it’s unclear why SpaceX chose to give SN7.2 a thrust dome, given that the thrust of Raptor engines can only be simulated with hydraulic rams if the tank is installed on one of two Starship launch mounts.
Regardless, whether SpaceX actually tests that aspect of SN7.2, the tank’s most important task is determining if future Starships (and perhaps Super Heavy boosters) can be built out of thinner, lighter steel rings. Its domes appear to be identical to past ships but writing on the exterior of the tank strongly implied that its three rings were built out of 3mm steel rather than the 4mm sheets that have made up every Starship built in the last 12 months.
SpaceX began loading the thin-skinned tank with liquid nitrogen (used to simulate cryogenic propellant without the risk of an explosion) around 9am CST and spent around three hours performing an “initial pressure test.” It’s unclear what that test entailed but it most likely involved raising the tank’s internal pressure to levels achieved by SN7.0 and SN7.1 Musk has previously said that that 6 bar was the bare minimum necessary for orbital flight, translating to 7.5-8.5 bar to achieve an industry-standard safety margin of 25-40%.
That SN7.2 survived that initial pressure test bodes well for the significant mass reductions SpaceX will need to optimize Starships for efficient orbital flight, potentially shaving 5-10 metric tons off the dry mass of future ships. For orbital rocket stages, every single kilogram of mass reduction translates to an extra kilogram of cargo capacity, whereas boost stages (i.e. Super Heavy) offer far more lenient ratios on the order to 10:1, meaning that adding 5-10 kilograms of rocket hardware reduces maximum payload capacity by just ~1 kg.
Depending on when SpaceX is allowed to launch Starship SN9, the company’s next test could involve pressurizing SN7.2 until it bursts, determining if the tank’s thinner skin substantially impacts its performance as a pressure vessel.
Elon Musk appeared on the Moonshots podcast with Peter Diamandis today to discuss AGI, U.S. vs. China, Tesla, and some other interesting topics, but there was some discussion about the upcoming unveiling of the Roadster, the company’s electric supercar that will arrive several years after it was initially slated for release.
Musk made some pretty amazing claims about the Roadster; we already know it is supposed to be lightning-fast and could even hover, if Tesla gets everything to happen the way it wants to. However, the car has some pretty crazy capabilities, some of which have not even been revealed.
On the podcast, Musk said:
“This is not a…safety is not the main goal. If you buy a Ferrari, safety is not the number one goal. I say, if safety is your number one goal, do not buy the Roadster…We’ll aspire not to kill anyone in this car. It’ll be the best of the last of the human-driven cars. The best of the last.”

Musk makes a good point: people who buy expensive sports cars with ridiculous top speeds and acceleration rates do not buy them to be safe. They hope they are safe in case of an emergency or crash, but safety is not at the forefront of their thoughts, because nobody buys a car thinking they’ll crash it.
The Roadster is truly going to push the limits and capabilities of passenger vehicles; there’s no doubt about that. Tesla plans to show off the new version car for the first time on April 1, and Musk has only hinted at what is possible with it.
Musk said back in November:
“Whether it’s good or bad, it will be unforgettable. My friend Peter Thiel once reflected that the future was supposed to have flying cars, but we don’t have flying cars. I think if Peter wants a flying car, he should be able to buy one…I think it has a shot at being the most memorable product unveiling ever. [It will be unveiled] hopefully before the end of the year. You know, we need to make sure that it works. This is some crazy technology in this car. Let’s just put it this way: if you took all the James Bond cars and combined them, it’s crazier than that.”
Production is set to begin between 12 and 18 months after the unveiling, which would put the car out sometime in 2027. Hopefully, Tesla is able to stay on track with the scheduling of the Roadster; many people have been waiting a long time for it.

Tesla launches hiring for Robotaxi program in its twentieth country
Overall, the hiring signals Tesla’s aggressive timeline for global dominance in autonomous mobility.
Tesla has launched a hiring initiative for its Robotaxi program in its twentieth country, as the company posted two new jobs in Thailand this week.
Tesla is hiring in Bangkok and Kowloon for the Vehicle Operator position, which is related to data collection, and is the first in Thailand, but the twentieth country overall, as the company tries to expand into other markets.
🚨 BREAKING: Tesla is hiring additional full-time Vehicle Operators in Bangkok, Thailand.
Previous openings were 6-month, part-time roles. These are equivalent to AI Safety Operator roles in the U.S. pic.twitter.com/R6LzoU1bos— Tesla Yoda (@teslayoda) January 5, 2026
Tesla has had active job postings for Vehicle Operator positions in the United States, India, Israel, Taiwan, Germany, the Czech Republic, Hungary, the UK, Finland, Switzerland, Sweden, the Netherlands, Austria, Spain, Norway, Italy, and Turkey in past listings.
These postings are not all currently available, likely because the roles have been filled.
Thailand is the most recent, and broadens the company’s potential path to expanding its ride-hailing program, which is only active in the United States in Austin, Texas, and the California Bay Area, so far.
These roles typically involve data collection, which assists in improving Autopilot and Full Self-Driving operation. Tesla’s self-driving programs utilize real-world data that is accumulated and stored, observing vehicle and traffic behavior, as well as tendencies that are performed by human drivers to help increase safety and overall performance.
Overall, the hiring signals Tesla’s aggressive timeline for global dominance in autonomous mobility. Although the company has several high-profile rivals and competitors in the field, it has established itself as a main player and a leader in the development of autonomous technology, especially in the U.S., as its FSD suite is refined on almost a weekly basis.
The Full Self-Driving suite is available in seven countries and territories currently, including the U.S., Canada, China, Mexico, Puerto Rico, Australia, and New Zealand. Its biggest goal for expansion is currently the European market, where regulatory hurdles have been the main bottleneck prolonging its launch on the continent.
Tesla has performed months of testing in various European countries, including France and Spain, and does have support in some areas from various regulatory agencies. However, the company is hoping to get through this red tape and offer its suite in Europe for the first time, hopefully this year.

Tesla China rolls out Model Y upgrades, launches low-interest financing
These strategies are aimed at improving the ownership experience and keeping vehicle pricing competitive in the world’s largest electric vehicle market.
Tesla has rolled out minor updates to the five-seat Model Y in China, upgrading the vehicle’s center display to a higher-resolution 16-inch 2K screen. The electric vehicle maker also introduced attractive financing options, including 7-year low-interest rates, to offset the new purchase tax on EVs.
These strategies are aimed at improving the ownership experience and keeping vehicle pricing competitive in the world’s largest electric vehicle market.
Five-seat Model Y gets larger, better display
With its recent update, all three variants of the five-seat Model Y now feature an upgraded 16-inch 2K resolution center display, which replaces the vehicle’s previous 15.4-inch 1080p panel. This screen was already used in the six-seat Model Y L, and it offered improved visual clarity. Tesla China has also updated the Model Y’s headliner to black, giving the vehicle a sleeker appearance.
Prices of the five-seat Model Y remain unchanged at RMB 263,500, RMB 288,500, and RMB 313,500 for the respective trims. This update enhances the cabin experience as domestic rivals are already adopting high-resolution screens. As noted in a CNEV Post report, some domestic automakers have begun rolling out vehicles equipped with 3K-resolution displays.
New financing offers
Tesla also launched ultra-long-term financing offers for its locally produced models in China, which include the Model 3 sedan, the five-seat Model Y, and the six-seat Model Y L, through January 31, 2026. The 7-year option features an annualized fee rate as low as 0.5%, which is equivalent to 0.98% interest. This is expected to save customers up to RMB 33,479 ($4,790) compared to standard rates.
A 5-year zero-interest plan is also available, and it has been extended to the Tesla Model Y L for the first time. These incentives help offset China’s new 5% purchase tax on New Energy Vehicles (NEVs) in 2026-2027. Some of Tesla’s rivals in China have announced in recent months that they would be covering the purchase tax owed by buyers early this year.
