‘Hot gas’ thrusters meant to boost the efficiency of SpaceX’s Starship spacecraft and Super Heavy boosters have been spotted in public for the first time.

On the evening of June 21st, spaceflight photographer Brady Kenniston – on assignment for NASASpaceflight – caught the first glimpses ever of what amounts to the newest rocket engine designed and built by SpaceX. As yet unnamed, SpaceX CEO Elon Musk has consistently referred to the new engine as a “hot gas thruster” for several years, though virtually no concrete details have ever been shared.

The reason behind the lack of major visible progress is simple enough: until Starship is ready for serious orbital testing, hot-gas thrusters just aren’t necessary. Instead, SpaceX has relied on tried and true cold gas thrusters derived – or quite literally taken, in the case of Starhopper – from those used on Falcon 9 and Falcon Heavy boosters to maintain attitude control in space and safely land back on Earth.

For Starhopper and Starships SN5 and SN6, all three of which focused on simple hop tests, those cold-gas thrusters primarily augmented Raptor’s thrust vectoring capabilities by fine-tuning vehicle rotation and attitude. On Starships SN8, SN9, SN10, SN11, and SN15, cold-gas thrusters played a more substantial role in their more complex medium-altitude test flights, flipping each ship horizontal at apogee, helping to maintain stability during skydiver-style freefalls back to Earth, and augmenting three Raptor engines during the final landing flip and landing burn.

By all appearances, the thrusters did their jobs perfectly on all nine test flights. However, those eight suborbital prototypes could all afford to expend large portions of their mass budgets on a plethora of pressure vessels filled with tons of nitrogen gas. More importantly, empty Starships and their Super Heavy boosters are expected to weigh anywhere from 10-50 times more than Falcon 9’s booster and upper stage, and SpaceX’s suborbital prototypes have also required much less performance (delta V) than operational ships and boosters will need.

Cold gas (nitrogen) thrusters are too inefficient and the exponential aspects of rocket engineering too cruel for what works on Falcon to efficiently meet the needs of Starship and Super Heavy. SpaceX’s long-planned solution has been the development of a bipropellant thruster that would borrow from Raptor expertise and use the same methane and oxygen propellant – albeit in their high-pressure gaseous forms. If properly realized, such a thruster could offer around five times the efficiency and thrust of a similarly-sized cold-gas system – a boon for maneuvering and manipulating massive 100-250 ton (~250,000-550,000 lb) ships and boosters in space.

In theory, moving from nitrogen to methalox thrusters also means that Starship could refuel its thrusters using a tiny fraction of the vast supply of liquid methane and oxygen propellant it will already be carrying to the Moon or Mars. Ultimately, though, Musk says that those hot gas attitude control thrusters will debut on the Super Heavy booster assigned to Starship’s first orbital test flight. While SpaceX’s initial July target now appears to be out of the question, all flight and pad hardware could still be ready to launch as early as August or September.

Update: One month after Elon Musk stated that SpaceX was “aiming” to have hot gas thrusters on the first flightworthy Super Heavy booster, the CEO says those thrusters would be “an unnecessary complication for now” and “are being removed to speed up time to” Starship’s first orbital launch.

Eric Ralph is Teslarati's senior spaceflight reporter and has been covering the industry in some capacity for almost half a decade, largely spurred in 2016 by a trip to Mexico to watch Elon Musk reveal SpaceX's plans for Mars in person. Aside from spreading interest and excitement about spaceflight far and wide, his primary goal is to cover humanity's ongoing efforts to expand beyond Earth to the Moon, Mars, and elsewhere.

Tesla Model Y sold out in China for 2025

Customers who wish to get their cars by the end of the year would likely need to get an inventory unit.

It appears that the Model Y has been sold out for 2025 in China. This seems to be true for the four variants of the vehicle that are currently offered in the country. 

Tesla China’s order page update

A look at Tesla China’s order page for the Model Y shows a message informing customers that those who wish to guarantee delivery by the end of the year should purchase an inventory unit. This was despite the Model Y RWD and Model Y L showing an estimated delivery timeline of 4-8 weeks, and the Model Y Long Range RWD and Model Y Long Range AWD showing 4-13 weeks. 

As per industry watchers, these updates on the Model Y’s order page suggest that Tesla China’s sales capacity for the remainder of 2025 has been sold out. The fact that estimated delivery timeframes for the Model Y Long Range RWD and AWD extend up to 13 weeks also bodes well for demand for the vehicle, especially given strong rivals like the Xiaomi YU7, which undercuts the Model Y in price. 

Tesla China’s upcoming big updates

What is quite interesting is that Tesla China is still competing in the country with one hand partly tied behind its back. So far, Tesla has only been able to secure partial approval for its flagship self-driving software, FSD, in China. This has resulted in V14 not being rolled out to the country yet. Despite this, Tesla China’s “Autopilot automatic assisted driving on urban roads,” as the system is called locally, has earned positive reviews from users.

As per Elon Musk during the 2025 Annual Shareholder Meeting, however, Tesla is expecting to secure full approval for FSD in China in early 2026. “We have partial approval in China, and we hopefully will have full approval in China around February or March or so. That’s what they’ve told us,” Musk said.

Tesla Full Self-Driving appears to be heading to Europe soon

For years, Musk has said the process for gaining approval in Europe would take significantly more time than it does in the United States. Back in 2019, he predicted it would take six to twelve months to gain approval for Europe, but it has taken much longer.

Tesla Full Self-Driving appears to be heading to Europe soon, especially as the company has continued to expand its testing phases across the continent.

It appears that the effort is getting even bigger, as the company recently posted a job for a Vehicle Operator in Prague, Czech Republic.

This would be the third country the company is seeking a Vehicle Operator in for the European market, joining Germany and Hungary, which already have job postings in Berlin, Prüm, and Budapest, respectively.

This position specifically targets the Engineering and Information Technology departments at Tesla, and not the Robotics and Artificial Intelligence job category that relates to Robotaxi job postings.

Although there has been a posting for Robotaxi Operators in the Eastern Hemisphere, more specifically, Israel, this specific posting has to do with data collection, likely to bolster the company’s position in Europe with FSD.

The job description says:

“We are seeking a highly motivated employee to strengthen our team responsible for vehicle data collection. The Driver/Vehicle Operator position is tasked with capturing high-quality data that contributes to improving our vehicles’ performance. This role requires self-initiative, flexibility, attention to detail, and the ability to work in a dynamic environment.”

It also notes the job is for a fixed term of one year.

The position requires operation of a vehicle for data collection within a defined area, and requires the Vehicle Operator to provide feedback to improve data collection processes, analyze and report collected data, and create daily driving reports.

The posting also solidifies the company’s intention to bring its Full Self-Driving platform to Europe in the coming months, something it has worked tirelessly to achieve as it spars with local regulators.

For years, Musk has said the process for gaining approval in Europe would take significantly more time than it does in the United States. Back in 2019, he predicted it would take six to twelve months to gain approval for Europe, but it has taken much longer.

This year, Musk went on to say that the process of getting FSD to move forward has been “very frustrating,” and said it “hurts the safety of the people of Europe.”

Tesla has crossed another major charging milestone by officially installing its 75,000th Supercharger stall worldwide. The electric vehicle maker chose South Hobart, Tasmania, as the commemorative location of its 75,000th Supercharger. 

Tesla’s 75,000th Supercharger

Tesla’s 75,000th stall is hosted at the South Hobart Smart Store on Cascade Road, South Hobart, TAS 7004, as noted in a techAU report. The location features four next-generation V4 Superchargers, which are built with longer cables that should make it easy even for non-Teslas to use the rapid charger. The site also includes simplified payment options, aligning with Tesla’s push to make V4 stations more accessible to a broader set of drivers.

For Tasmanian EV owners, the installation fills an important regional gap, improving long-distance coverage around Hobart and strengthening the area’s appeal for mainland travelers traveling by electric vehicle. Similar to other commemorative Superchargers, the 70,000th stall is quite special as it is finished in Glacier Blue paint. Tesla’s 50,000th stall, which is in California, is painted a stunning red, and the 60,000th stall, which is in Japan, features unique origami-inspired graphics.

Accelerating Supercharger milestones

The Tesla Supercharger’s pace of expansion shows no signs of slowing. Tesla celebrated its 70,000th stall at a 12-stall site in Burleson, Texas late June 2025. Just eight months earlier, Tesla announced that it had celebrated the buildout of its 60,000th Supercharger, which was built in Enshu Morimachi, Shizuoka Prefecture, Japan.

Tesla’s Supercharger Network also recently received accolades in the United Kingdom, with the 2025 Zapmap survey naming the rapid charging system as the Best Large EV Charging Network for the second year in a row. Survey respondents praised the Supercharger Network for its ease of use, price, and reliability, which is best-in-class. The fact that the network has also been opened for non-Teslas is just icing on the cake.
