After a four-day delay, SpaceX has successfully installed the first high-altitude Starship at its Boca Chica launch pad not long after the rocket was outfitted with large flaps.

Technically the second time a Starship was outfitted with flaps, Starship serial number 8 had the bottom half of its aerodynamic control surfaces installed on September 23rd – exactly one year after Starship Mk1’s flaps were first installed. Starship Mk1’s flaps were likely meant to be functional but SpaceX never appeared to activate them and Mk1’s main body (tank section) was destroyed during a November 2019 pressure test, failing far before the necessary pressures for flight tests. As such, barring a surprise or two, Starship SN8 will very likely become the first flightworthy prototype to have functional flaps installed.

That remains to be seen, though, and will be put to the test over the next few weeks. If all goes according to plan, the ship could become the first to attempt a high-altitude, 15 km (9.3 mile) launch and landing testing, likely also becoming the first Starship to break the sound barrier.

Starship SN8’s first steps toward testing began on September 26th when SpaceX loaded the rocket onto a self-propelled mobile transporter (SPMT) and rolled it to the company’s dedicated Boca Chica launch and test facilities. Shortly after arrival, a crane and load spreader was attached to the rocket to lift it onto one of the pad’s test stands (Stand A). That lift never came and the crane eventually detached and retracted, kicking off what would become an unusual four-day delay.

It’s believed that the relatively high winds on the Boca Chica coast were to blame, creating conditions that were too hazardous to risk the precise, hands-on work required to lift and manipulate a ~70 metric ton (~150,000 lb) rocket. While undeniably heavy, an empty Starship’s huge surface area effectively turns it into a giant sail, catching and amplifying wind gusts. Attaching a Starship to a launch mount’s hold-down clamps likely demands millimeter precision, making installation and high winds obviously incompatible (or at least inadvisable).

Finally, around midnight on September 30th, winds died down in Boca Chica and SpaceX fired up a waiting crane and lifted Starship SN8 onto the launch mount. Soon after, technicians began the process of installing the mount’s temporary hydraulic ram – used to mechanically simulate engine thrust – to the rocket’s ‘thrust puck’.

Like every Starship prototype since Mk1, Starship SN8’s first major challenge will involve passing an acceptance test known as a “cryogenic proof.” After being pressurized with ambient-temperature nitrogen gas to check for leaks, SN8 will be fully filled with liquid nitrogen while the hydraulic ram subjects its thrust puck and engine section to stresses similar to the thrust of three Raptor engines. Together, three Raptors are capable of producing more than 600 metric tons (1.3 million lbf) of thrust. For reference, four Raptors would effectively match the thrust of an entire Falcon 9 booster with all nine Merlin 1Ds at full throttle.

If SN8 reaches the necessary pressure and survives the stress of its cryo proof(s), it will likely become the first Starship to attempt a triple-Raptor static fire – a first for the engine, too. Starship SN8’s first cryo proof attempt is scheduled no earlier than 9pm-6am CDT (UTC-5) on Sunday, October 4th with backup windows on the 5th and 6th. The first static fire attempt – possibly beginning with one Raptor or jumping straight to three – could happen several days after a successful cryo proof.

According to Elon Musk, SpaceX will static fire SN8 twice before attempting its 15 km (~50,000 ft) launch debut. More likely than not, SpaceX will attempt a triple-engine static fire with the Starship as-is, install SN8’s nosecone and forward flaps, and attempt a second static fire while only drawing propellant from tbe rocket’s smaller header tanks (one of which is located in the tip of its nose). Only time (or Elon tweets) will tell.

Tesla Cybercab includes this small but significant feature

The Cybercab is Tesla’s big plan to introduce fully autonomous ride-sharing in a seamless fashion. In fact, the Full Self-Driving suite was geared toward alleviating the need to manually drive vehicles.

Tesla Cybercab manufacturing is strikingly close, as the company is still aiming for an April start date. But small and significant features are still being identified for the first time as production units appear all over the country for testing and for regulatory events, like one yesterday in Washington, D.C.

The Cybercab is Tesla’s big plan to introduce fully autonomous ride-sharing in a seamless fashion. In fact, the Full Self-Driving suite was geared toward alleviating the need to manually drive vehicles.

This was for everyone, including the disabled, who are widely reliant on ride-sharing platforms, family members, and medical shuttles for transportation of any kind. Cybercab aims to change that, and Tesla evidently put a focus on those riders while developing the vehicle, evident in a small but significant feature revealed during its appearance in the Nation’s Capital.

Tesla has implemented Braille within the Cybercab to make it easier for blind passengers to utilize the vehicle. On both the ‘Stop/Hazard Lights’ button and the Door Releases, Tesla has placed Braille so that blind passengers can navigate their way through the vehicle:

This is a great addition to the Cybercab, especially as Full Self-Driving has been partially pointed at as a solution for those with disabilities that would keep them from driving themselves from place to place.

It truly is a great addition and just another way that Tesla is showing they are making this massive product inclusive for everyone out there, including those who have not been able to drive due to not having vision.

The Cybercab is set to enter mass production sometime in April, and it will be responsible for launching Tesla’s massive plans for an autonomous ride-sharing program.

Tesla and xAI team up on massive new project

It is the latest move by a Musk company to automate, streamline, and reduce the manual, monotonous, and tedious work currently performed by humans through AI and robotics development. Digital Optimus will be capable of processing and actioning the past five seconds of a real-time computer screen video and keyboard and mouse actions.

Elon Musk teased a massive new project, to be developed jointly by Tesla and xAI, called “Digital Optimus” or “Macrohard,” the first development under Tesla’s investment agreement with xAI.

Musk announced on X that Digital Optimus will “be capable of emulating the function of entire companies.”

It is the latest move by a Musk company to automate, streamline, and reduce the manual, monotonous, and tedious work currently performed by humans through AI and robotics development. Digital Optimus will be capable of processing and actioning the past five seconds of a real-time computer screen video and keyboard and mouse actions.

Essentially, it will be an AI version of a desk worker in many capacities, including accounting, HR tasks, and others.

Musk said:

“Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of real-time computer screen video and keyboard/mouse actions. Grok is like a much more advanced and sophisticated version of turn-by-turn navigation software. You can think of it as Digital Optimus AI being System 1 (instinctive part of the mind) and Grok being System 2. (thinking part of the mind).”

Its key applications would be used for enterprise automation, simulating entire companies, high-volume repetitive tasks, and potentially, future hybrid use with the Optimus robot, which would handle physical tasks, while Digital Optimus would handle the clerical work.

Tesla announces massive investment into xAI

The creation of a digital AI suite like Digital Optimus would help companies save time and money, as well as become more efficient in their operations through massive scalability. However, there will undoubtedly be concerns from people who are skeptical of a fully-integrated AI workhorse like this one.

From an energy consumption perspective and just a general concern for the human workforce, these types of AI projects are polarizing in nature.

However, Digital Optimus would be a great digital counterpart to Tesla’s physical Optimus robot, as it would be a hyper-efficient addition to any company that is looking for more production for less cost.

Musk maintains that there is no other company on Earth that will be able to do this.

Tesla China sold 58,599 vehicles wholesale in February, reflecting strong year-over-year growth. The figure includes both domestic deliveries in China and vehicles exported to international markets.

The update was shared by Tesla observers on social media platform X, citing monthly China Passenger Car Association (CPCA) data.

Tesla’s February wholesale result represents a 91% increase year over year, compared with 30,688 vehicles in February 2025. Month over month, the result was down 15.2% from January, when Tesla China recorded 69,129 wholesale units.

The February total reflects combined sales of the Model 3 and Model Y produced at Gigafactory Shanghai. The facility produces the two vehicles for both domestic sales and exports.

Gigafactory Shanghai continues to serve as Tesla’s primary vehicle export hub, supplying vehicles to markets across Asia and Europe. Data compiled by Tesla watchers shows that 18,485 vehicles were sold domestically in China in January 2026, while exports accounted for 50,644 units during the same period.

Tesla has also been extending financing programs in China as it pushes to strengthen domestic demand. The company recently extended its seven-year ultra-low-interest and five-year interest-free financing programs through March 31, marking the second extension of the promotion this year.

The financing initiative was first introduced on January 6 as a strategy aimed at offsetting higher ownership costs ahead of China’s planned 5% NEV purchase tax in 2026. The promotion was originally scheduled to expire at the end of January before being extended to February and then again through the end of the first quarter.

Tesla’s efforts come amid growing competition in China’s EV market. According to data compiled by CNEV Post, Tesla’s 2025 retail sales in China reached 625,698 vehicles, representing a 4.78% year-over-year decline. Part of that decline was linked to the Model Y changeover to its updated variant in early 2025, which temporarily reduced deliveries during the transition period.
