In a small but important step towards activating a pad capable of launching the largest and most powerful rocket ever built, SpaceX has ‘sleeved’ one of its Starship-derived propellant storage tanks for the first time.

Starship is a fully-reusable, two-stage liquid rocket designed to ultimately cut the cost of orbital launch by at least one magnitude, opening the door for humanity’s sustainable expansion to Earth orbit, the Moon, Mars, and even beyond. To accomplish that lofty feat, it has to be a massive rocket. Measuring approximately 120m (~395 ft) tall and 9m (~30 ft) wide, Starship and Super Heavy will weigh on the order of 300 metric tons (~675,000 lb) when empty.

Once filled to the brim with cryogenic liquid methane (CH4) and liquid oxygen (LOx) propellant and gas, though, a two-stage Starship will easily weigh more than 5000 tons (11 million lb) shortly before and after liftoff. Further, SpaceX wants to be able to launch at least two Starships from Boca Chica in rapid succession. To meet the staggering needs of back-to-back Starship launches, SpaceX has thus had to design and build what will be the world’s largest launch pad tank farm.

Work on that tank farm is already well underway, though progress has been slower than expected. The site’s foundation and a few associated blockhouses were mostly completed by January 2021. By early April, the company had completed the first of at least seven steel propellant storage tanks at its Starship factory and rolled it to the launch pad for installation.

Notably, SpaceX chose to manufacture those storage tanks itself and ended up building structures virtually identical to the tanks that already make up most of flightworthy Starship and Super Heavy airframes. Depending on whether they’re meant to store liquid oxygen or methane, the seven tanks SpaceX is building are either 26 or 30 meters (85 or 100 feet) tall – though the concrete mounts they’re affixed to at the launch site are sized such that all storage tanks will have the same final height.

Of course, being made with the same tools and out of the same steel as Starship and Super Heavy, that means that SpaceX’s custom storage tanks are little more than 4mm (~1/6″) thick steel shells – about as bad as it gets for keeping cryogenic rocket fuel… cryogenic. If SpaceX were to simply use those unmodified tanks, it would be almost impossible to store Starship fuel for more than a few hours – and maybe just a few minutes – without it warming up past the point of usability.

As such, SpaceX’s final Starship tank farm design involves seven Starship-derived storage tanks and seven contractor-built tank sleeves. Measuring around 12m (~40 ft) wide and 40m (~130 ft) tall, those “cryo shells” will enclose all seven SpaceX-built tanks, allowing the company to fill the 1.5m (~5 ft) gap between them with an insulating solid, gas, or some combination of both. With those shells and insulation, SpaceX’s custom-built Starship tank form should be more than capable of storing cryogenic liquid oxygen and methane for days or even weeks.

As of August 5th, SpaceX has installed three of Starship’s custom ground supply equipment (GSE) tanks (with a fourth moved onsite on Thursday), moved two ‘cryo shells’ to temporary storage spots at the pad, and installed one cryo shell that actually turned out to be a million-gallon water tank. On Thursday, SpaceX ‘sleeved’ one of those storage tanks for the first time ever, marking an important milestone towards the activation of a tank farm capable of supporting Starship’s orbital launch debut. Another four sleeves are more or less complete, with the eighth and final sleeve likely just a week or two away from completion.

A fifth GSE tank is also more or less complete, leaving two more to go. However, with some basic math, it’s possible to determine that SpaceX’s orbital launch pad likely only needs five cryogenic tanks (three oxygen, two methane) – and possibly as few as four – to support Starship’s first orbital test flight(s). With SpaceX finally beginning to install tank sleeves, it’s possible that that four or five-tank milestone – and the first tests of SpaceX’s custom, unproven storage solution – are now much closer at hand.

Tesla Model 3 hits quarter million miles with original battery and motor

The Model 3’s Battery Management System (BMS) shows a State of Health between 88% and 90%.

A Western Australian Tesla Model 3 has captured global attention after racking up an impressive 410,000 kilometers (254,000 miles) on its original battery and motor, while still retaining around 90% of its original battery health.

Long-term Model 3

The 2021 Model 3 Standard Plus, equipped with a 60 kWh lithium iron phosphate (LFP) battery, has been in constant use as an Uber rideshare vehicle. According to Port Kennedy EV specialist EV Workz, the car’s Battery Management System (BMS) shows a State of Health between 88% and 90%.

EV Workz owner Edi Gutmanis shared the findings on Facebook’s Electric Vehicles For Australia page on August 8, and the post quickly went viral. As per Gutmanis, the Model 3’s charging history shows 15,556 kWh delivered via DC fast charging (29% of the total) and 38,012 kWh via AC charging (71% of the total). 

Gutmanis also broke down the fuel savings for the Model 3. A petrol car covering the same 410,000 km at 7L/100km and $1.70 per liter would cost an estimated AU$50,000 in fuel. By comparison, charging the Tesla using average commercial rates would be about AU$20,737 and just AU$13,000 if using Western Australia’s EV tariff. That’s a potential refueling saving of roughly $37,000, not including the avoided maintenance costs of an internal combustion engine.

Simple fix

The car came into EV Workz for a driveline “judder” issue, as per a report form EV Central Australia. Gutmanis found the real cause was simply worn motor mount bushes. After seven hours of labor and $130 in parts, “the car drives just as good as the first day it left the dealership,” Gutmanis said.

Gutmanis, whose business also performs EV conversions on classics and 4x4s, says the results aren’t surprising. “We expect this sort of longevity with EV batteries,” he explained, though this is the highest-mileage Model 3 he has encountered in Australia.

A fleet of mysterious covered Model Y units has been spotted at the Giga Berlin complex. The vehicles were sighted during a recent drone flyover of the Germany-based Model Y production site.

A mysterious fleet

The mysterious Model Y fleet was sighted by longtime Giga Berlin watcher Tobias Lindh, who has been chronicling the progress and activities of Tesla’s German factory complex for years. During his flyover on August 12, 2025, Lindh noted that he was able to spot a fleet of fully covered Model Y units being gathered in one section of the Giga Berlin site.

The presence of the covered Model Y units caught a lot of attention online, with numerous Tesla watchers speculating if the vehicles were the Model Y L or the yet-to-be-released Model Y Performance. Giga Berlin only produces Model Y units, after all, and both the Model Y L and Model Y Performance are yet to be rolled out by the electric vehicle maker.

Tesla Model Y Performance the Model Y L

The Model Y is Tesla’s best-selling vehicle by a mile, selling so well that it was able to become the world’s best-selling car by volume in 2023. With the changeover to the new Model Y this year, Tesla has only released the vehicle’s updated RWD and AWD versions. The updated Model Y Performance is yet to be released as of writing, though sightings of apparent Model Y Performance units have been reported on social media.

In recent weeks, however, the Model Y news cycle has been dominated by the upcoming release of the Model Y L, an extended wheelbase, six-seat version of the best-selling all-electric crossover. The Model Y L is expected to be produced in Giga Shanghai initially, though Giga Berlin, the Fremont Factory, and Giga Texas are also expected to produce the variant in the near future.

Ukraine’s largest mobile operator, Kyivstar, has completed its first test of Starlink’s Direct to Cell satellite technology, enabling text messages to be sent directly from 4G smartphones without extra hardware. 

The trial was announced by the Ministry of Digital Transformation and Kyivstar’s parent company Veon in a press release.

First Eastern Europe field test

The Zhytomyr region hosted the pilot, where Deputy Prime Minister Mykhailo Fedorov and Kyivstar CEO Oleksandr Komarov exchanged texts and even made a brief video call via Starlink’s satellite link in northern Ukraine’s Zhytomyr region. 

Veon stated that the test marked Eastern Europe’s first field trial of the technology, which will allow Kyivstar’s 23 million subscribers to stay connected in areas without cellular coverage. The service will debut in fall 2025 with free text messaging during its testing phase.

“Our partnership with Starlink integrates terrestrial networks with satellite platforms, ensuring that nothing stands between our customers and connectivity – not power outages, deserts, mountains, floods, earthquakes, or even landmines,” Veon CEO Kaan Terzioglu stated.

Starlink in Ukraine

Kyivstar signed its Direct to Cell agreement with Starlink in December 2024, about a year after a major cyberattack disrupted service and caused nearly $100 million in damages, as noted in a report from the Kyiv Independent. Starlink technology has been a pivotal part of Ukraine’s defense against Russia in the ongoing conflict.

“Despite all the challenges of wartime, we continue to develop innovative solutions, because reliable communication under any circumstances and in any location is one of our key priorities. Therefore, this Kyivstar project is an example of effective partnership between the state, business, and technology companies, which opens the way to the future of communication without borders,” Mykhailo Fedorov, First Deputy Prime Minister of Ukraine, said.
