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 hasn’t adopted Apple CarPlay yet for this shocking reason

Many Apple and iPhone users have wanted the addition, especially to utilize third-party Navigation apps like Waze, which is a popular alternative. Getting apps outside of Tesla’s Navigation to work with its Full Self-Driving suite seems to be a potential issue the company will have to work through as well.

Perhaps one of the most requested features for Tesla vehicles by owners is the addition of Apple CarPlay. It sounds like the company wants to bring the popular UI to its cars, but there are a few bottlenecks preventing it from doing so.

The biggest reason why CarPlay has not made its way to Teslas yet might shock you.

According to Bloomberg‘s Mark Gurman, Tesla is still working on bringing CarPlay to its vehicles. There are two primary reasons why Tesla has not done it quite yet: App compatibility issues and, most importantly, there are incredibly low adoption rates of iOS 26.

Tesla’s Apple CarPlay ambitions are not dead, they’re still in the works

iOS 26 is Apple’s most recent software version, which was released back in September 2025. It introduced a major redesign to the overall operating system, especially its aesthetic, with the rollout of “Liquid Glass.”

However, despite the many changes and updates, Apple users have not been too keen on the iOS 26 update, and the low adoption rates have been a major sticking point for Tesla as it looks to develop a potential alternative for its in-house UI.

It was first rumored that Tesla was planning to bring CarPlay out in its cars late last year. Many Apple and iPhone users have wanted the addition, especially to utilize third-party Navigation apps like Waze, which is a popular alternative. Getting apps outside of Tesla’s Navigation to work with its Full Self-Driving suite seems to be a potential issue the company will have to work through as well.

According to the report, Tesla asked Apple to make some changes to improve compatibility between its software and Apple Maps:

“Tesla asked Apple to make engineering changes to Maps to improve compatibility. The iPhone maker agreed and implemented the adjustments in a bug fix update to iOS 26 and the latest version of CarPlay.”

Gurman also said that there were some issues with turn-by-turn guidance from Tesla’s maps app, and it did not properly sync up with Apple Maps during FSD operation. This is something that needs to be resolved before it is rolled out.

There is no listed launch date, nor has there been any coding revealed that would indicate Apple CarPlay is close to being launched within Tesla vehicles.

Starlink restrictions are hitting Russian battlefield comms: report

The restrictions have reportedly disrupted Moscow’s drone coordination and frontline communications.

SpaceX’s decision to disable unauthorized Starlink terminals in Ukraine is now being felt on the battlefield, with Ukrainian commanders reporting that Russian troops have struggled to maintain assault operations without access to the satellite network. 

The restrictions have reportedly disrupted Moscow’s drone coordination and frontline communications.

Lt. Denis Yaroslavsky, who commands a special reconnaissance unit, stated that Russian assault activity noticeably declined for several days after the shutdown. “For three to four days after the shutdown, they really reduced the assault operations,” Yaroslavsky said.

Russian units had allegedly obtained Starlink terminals through black market channels and mounted them on drones and weapons systems, despite service terms prohibiting offensive military use. Once those terminals were blocked, commanders on the Ukrainian side reported improved battlefield ratios, as noted in a New York Post report.

A Ukrainian unit commander stated that casualty imbalances widened after the cutoff. “On any given day, depending on your scale of analysis, my sector was already achieving 20:1 (casuality rate) before the shutdown, and we are an elite unit. Regular units have no problem going 5:1 or 8:1. With Starlink down, 13:1 (casualty rate) for a regular unit is easy,” the unit commander said.

The restrictions come as Russia faces heavy challenges across multiple fronts. A late January report from the Center for Strategic and International Studies estimated that more than 1.2 million Russian troops have been killed, wounded, or gone missing since February 2022.

The Washington-based Institute for the Study of War also noted that activity from Russia’s Rubikon drone unit declined after Feb. 1, suggesting communications constraints from Starlink’s restrictions may be limiting operations. “I’m sure the Russians have (alternative options), but it takes time to maximize their implementation and this (would take) at least four to six months,” Yaroslavsky noted.

Elon Musk echoed the hiring push in a separate post. “If you’re in Korea and want to work on chip design, fabrication or AI software, join Tesla!” he wrote.

The recruitment effort in South Korea comes as Tesla accelerates development of its in-house AI chips, which power its Full Self-Driving (FSD) system, Optimus humanoid robot, and data center training infrastructure.

Tesla has been steadily expanding its silicon development teams globally. In recent months, the company has posted roles in Austin and Palo Alto for silicon module process engineers across lithography, etching, and other chip fabrication disciplines, as noted in a Benzinga report.

Tesla Korea’s hiring efforts align with the company’s long-term goal of designing and producing AI chips at massive scale. Musk has previously stated that Tesla’s future AI chips could become the highest-volume AI processors in the world.
