Four days after the rocket’s hop debut, SpaceX has safely returned its second flight-proven Starship prototype to an assembly building for refurbishment, making way for a new ‘test tank’ at the launch pad.

Known as Starship serial number six (SN6), the ~30m (~100 ft) tall prototype became the second full-scale Starship to take flight on September 3rd, following in SN5’s footsteps to reach a similar ~150m (~500 ft) apogee before gently landing. More or less identical to SN5’s own August 4th hop debut, it marked the second hop of an entirely separate Starship prototype in 30 days – a feat almost certainly unprecedented in the history of large-scale rocket development.

Significant work remains to speed up the post-hop process, which appears to currently amount to some ~48 hours of gradual, uncontrolled detanking and depressurization. Regardless, a bit least than four days after a successful launch and landing, Starship SN6 was rolled back to SpaceX’s Boca Chica, Texas production facilities around 9am CDT, September 7th. Just five hours after that, Starship test tank SN7.1 – the second in a planned series of two – was loaded onto the same transporter and shipped down the road to the launch pad.

Since its first hop, over the last 30 days, SpaceX has inspected and refurbished Starship SN5 to help support what CEO Elon Musk has described as “several short hops to smooth out [the] launch process.” SN6’s success (and the intact launch infrastructure it thus left behind) now means that SN5 will almost certainly be reused in the near future. It’s unclear how many hops will be needed for Starship launch operations to be optimized into a smooth process but 4+ (2 x SN5, 2 x SN6) seems to be a safe bet.

However, SN5’s second hop will have to wait. Up next on SpaceX’s South Texas manifest is the fifth in a series of intentionally destructive tank tests, used to qualify (or disqualify) new Starship designs, manufacturing techniques, and materials. Known as Starship SN7.1, this particular test tank is the second in a series of two meant to determine the capabilities of a new steel alloy.

The first tank, SN7, was (successfully) tested to destruction on June 23rd and is believed to have reached record pressures before it failed. Perhaps more importantly, an unintentional leak during one of SN7’s first pressure test attempts proved that the new 304L (-ish) steel alloy it was built out of would make certain failure modes far less catastrophic (i.e. a leak instead of a violent rupture).

SN7 was a single basic test tank: an upper dome, lower dome, and three steel rings. SN7.1 is significantly more complex, adding a skirt section with hold-down clamps at the base and replacing the aft tank dome with a thrust dome and thrust puck (Raptor engine attachment points). SN7 was simply loaded with cryogenic liquid nitrogen and pressurized. SN7.1 – thanks to the addition of a thrust puck and skirt section – will perform similar cryo pressure tests but will also be subject to the simulated thrust of three Raptor engines with a series of hydraulic rams.

As of now, SpaceX has road closures scheduled today and tomorrow (Sept 8th) from 8am to 8pm CDT – tomorrow likely being the earliest opportunity for SN7.1 testing to begin.

Tesla Supercharger left offline as Swedish court backs union strike

The completed Supercharger has been stalled for nearly two years amid Tesla’s conflict with the IF Metall union in Sweden.

Tesla’s Supercharger station in Ljungby, Sweden will remain without power after a Swedish administrative court rejected the company’s appeal to force a grid connection to the site. The completed Supercharger has been stalled for nearly two years amid Tesla’s conflict with the IF Metall union in Sweden.

The court ruled that the ongoing union strike against Tesla Sweden is valid grounds for the Supercharger’s connection delay, as noted in an Allt Om Elbil report. 

The Ljungby Supercharger was one of the first charging stations that were denied grid access after IF Metall launched its strike against Tesla Sweden in late 2023. Electricians at local grid operator Ljungby Energinät were pulled into a sympathy strike by the Seko union, preventing the site’s connection.

Tesla reported both Ljungby Energinät and Gävle Energi Elnät AB to the Swedish Energy Market Inspectorate, arguing that grid operators failed to meet their legal obligation to provide connection to the location within a reasonable time frame.

The regulator ruled that the strike represented a valid exception under Swedish law, however, citing constitutional protections for industrial actions.

Tesla responded by appealing to the Administrative Court in Linköping, claiming it had the right to connection within a reasonable period, generally no more than two years. Tesla Sweden also argued that the country’s Electricity Act conflicts with EU law. The court rejected those arguments.

“The Administrative Court today finds that granting the company’s request in practice applies to the same thing as the blockade and that it would mean that the blockade would be ineffective. 

“Such a decision would contradict the principle that labor market conflicts should be resolved to the greatest extent possible by the labor market parties, not by the state. The industrial action is also constitutionally protected,” Chief Councilor Ronny Idstrand stated.

The court also concluded that the Electricity Act does not conflict with EU regulations and that special reasons justified the extended delay.

While the ruling was unanimous, Tesla Sweden may appeal the decision to a higher administrative court.

Tesla China exports 50,644 vehicles in January, up sharply YoY

The figure also places Tesla China second among new energy vehicle exporters for the month, behind BYD.

Tesla China exported 50,644 vehicles in January, as per data released by the China Passenger Car Association (CPCA).

This marks a notable increase both year-on-year and month-on-month for the American EV maker’s Giga Shanghai-built Model 3 and Model Y. The figure also places Tesla China second among new energy vehicle exporters for the month, behind BYD.

The CPCA’s national passenger car market analysis report indicated that total New Energy Vehicle exports reached 286,000 units in January, up 103.6% from a year earlier. Battery electric vehicles accounted for 65% of those exports.

Within that total, Tesla China shipped 50,644 vehicles overseas. By comparison, exports of Giga Shanghai-built Model 3 and Model Y units totaled 29,535 units in January last year and just 3,328 units in December.

This suggests that Tesla China’s January 2026 exports were roughly 1.7 times higher than the same month a year ago and more than 15 times higher than December’s level, as noted in a TechWeb report.

BYD still led the January 2026 export rankings with 96,859 new energy passenger vehicles shipped overseas, though it should be noted that the automaker operates at least nine major production facilities in China, far outnumering Tesla. Overall, BYD’s factories in China have a domestic production capacity for up to 5.82 million units annually as of 2024.

Tesla China followed in second place, ahead of Geely, Chery, Leapmotor, SAIC Motor, and SAIC-GM-Wuling, each of which exported significant volumes during the month. Overall, new energy vehicles accounted for nearly half of China’s total passenger vehicle exports in January, hinting at strong overseas demand for electric cars produced in the country.

China remains one of Tesla China’s most important markets. Despite mostly competing with just two vehicles, both of which are premium priced, Tesla China is still proving quite competitive in the domestic electric vehicle market.

Tesla has added a new feature to its Navigation and Supercharger Map in preparation for a new vehicle to hit the road: the Semi.

After CEO Elon Musk announced earlier this week that the Semi’s mass production processes were scheduled for later this year, the company has been making various preparations as it nears manufacturing.

Elon Musk confirms Tesla Semi will enter high-volume production this year

One of those changes has been the newly-released information regarding trim levels, as well as reports that Tesla has started to reach out to customers regarding pricing information for those trims.

Now, Tesla has made an additional bit of information available to the public in the form of locations of Megachargers, the infrastructure that will be responsible for charging the Semi and other all-electric Class 8 vehicles that hit the road.

Tesla made the announcement on the social media platform X:

Although it is a minor development, it is a major indication that Tesla is preparing for the Semi to head toward mass production, something the company has been hinting at for several years.

Nevertheless, this, along with the other information that was released this week, points toward a significant stride in Tesla’s progress in the Semi project.

Now that the company has also worked toward completion of the dedicated manufacturing plant in Sparks, Nevada, there are more signs than ever that the vehicle is finally ready to be built and delivered to customers outside of the pilot program that has been in operation for several years.

For now, the Megachargers are going to be situated on the West Coast, with a heavy emphasis on routes like I-5 and I-10. This strategy prioritizes major highways and logistics hubs where freight traffic is heaviest, ensuring coverage for both cross-country and regional hauls.

California and Texas are slated to have the most initially, with 17 and 19 sites, respectively. As the program continues to grow, Florida, Georgia, Illinois, Washington, New York, and Nevada will have Megacharger locations as well.

For now, the Megachargers are available in Lathrop, California, and Sparks, Nevada, both of which have ties to Tesla. The former is the location of the Megafactory, and Sparks is where both the Tesla Gigafactory and Semifactory are located.
