SpaceX has installed a pair of rocket-catching arms on a tower meant to support the first East Coast launches of its next-generation Starship rocket.

The company has been building the second of several planned Starship launch sites for more than three years. Ironically, work on that pad began before the company started building the pad that will actually support Starship’s first orbital launch attempts. Located a stone’s throw from the Gulf of Mexico in Boca Chica, Texas, the first iteration of SpaceX’s Starbase orbital launch site (OLS) is nearly complete and could host Starship’s orbital launch debut in a matter of months. SpaceX began constructing Starship’s Texas launch site in earnest in late 2020.

SpaceX broke ground on Starship’s first Florida OLS in late 2019. But the company went on to radically redesign the rocket and its ground systems, forcing it to entirely abandon about a year of work by the end of 2020. In late 2021, SpaceX finally began constructing the second iteration of Starship’s first Florida pad. OLS #2 is still colocated at Kennedy Space Center’s LC-39A pad, which SpaceX leases from NASA. Pad 39A is the only site currently capable of launching SpaceX’s Crew Dragon astronaut spacecraft or Falcon Heavy rocket, which has complicated its plans to use the same pad for Starship.

Because of NASA’s trepidation at the thought of a Starship failure indefinitely delaying SpaceX from completing its Crew Dragon or Falcon Heavy contracts for the agency, the company deprioritized Starship’s Florida pad, slowing progress. SpaceX has, nonetheless, made significant progress. In 13 months, SpaceX has created foundations, modified one of Pad 39A’s giant spherical tanks to store cryogenic methane, installed miles of plumbing, built and assembled a second skyscraper-sized Starship launch tower, installed the legs of the pad’s ‘orbital launch mount’ or OLM, installed a water deluge system at the base of the OLM, assembled most of the OLM’s donut-like mount offsite, constructed a new supersized storage tank, and delivered a forest of smaller storage tanks.

Most recently, SpaceX finished building a giant pair of steel arms, transported the arms to Pad 39A, attached them to a wheeled carriage, and installed the structure on Starship’s Florida launch tower. SpaceX employees have nicknamed the arms “chopsticks,” and those arms are integral to what CEO Elon Musk calls “Mechazilla”. Mechazilla refers to the combined launch tower and arms, which SpaceX has designed to grab, lift, stack, and fuel both stages of Starship.

Mechazilla’s simplest part is a third arm that is vertically fixed in place but capable of swinging left and right. The swing arm contains plumbing and an umbilical device that connects to Starship’s upper stage and supplies propellant, gas, power, and connectivity. The tower’s ‘chopsticks’ are far more complex. Giant hinges connect the pair of arms to a carriage that grabs onto three of the tower’s four legs with a dozen skate-like appendages. Those skates are outfitted with wheels, allowing the carriage to roll up and down tracks built into the tower’s legs.

The carriage, which also carries the complex hydraulic systems that allow its bus-sized arms to move, is connected by steel cable to a heavy-duty “draw works” capable of hoisting the multi-hundred-ton assembly up and down the tower. Once finished, the Florida tower’s arms will be able to precisely lift, maneuver, stack, and de-stack Starship and Super Heavy even in relatively windy conditions. At some point in the future, SpaceX may attempt to use its towers and chopsticks to catch Starships and Super Heavies out of mid-air and speed up reuse.

Set to be the largest, most powerful, and most capable rocket in history, Starship is primarily built out of steel and designed to be fully reusable. SpaceX has a long way to go to demonstrate that the 120-meter-tall (~390 ft) rocket can reach orbit, let alone be reused. In theory, though, Starship is meant to launch up to 150 metric tons (330,000 lb) to low Earth orbit (LEO) while still allowing for the recovery and reuse of its suborbital Super Heavy booster and orbital Starship upper stage.

If SpaceX can achieve those figures, Starship will be the most capable rocket in history even with the major performance penalties that full reusability entails. Saturn V, the most capable rocket ever flown, was fully expendable and could launch up to 118 metric tons (~260,000 lb) into orbit.

Due to NASA’s concerns about the risks that Starship launches from Pad 39A could pose to SpaceX’s Falcon and Dragon operations at the same site, the company’s next-generation rocket may have to wait until 2024 or 2025 for its first Florida launch. With the first Florida Mechazilla now close to completion, it’s likely that Pad 39A’s Starship launch site will be ready and waiting as soon as NASA gives SpaceX the green light.

Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk. 

The Tesla CEO shared his recent insights in a post on social media platform X.

Musk details AI chip roadmap

In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle. 

He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.

Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.

AI5 manufacturing takes shape

Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.

Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.

Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.

The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.

According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.

The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring. 

This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.

The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.  

ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.

“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.

“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.

Tesla Sweden uses Megapack battery to bypass unions’ Supercharger blockade

Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery.

Tesla Sweden has successfully launched a new Supercharger station despite an ongoing blockade by Swedish unions, using on-site Megapack batteries instead of traditional grid connections. The workaround has allowed the Supercharger to operate without direct access to Sweden’s electricity network, which has been effectively frozen by labor action.

Tesla has experienced notable challenges connecting its new charging stations to Sweden’s power grid due to industrial action led by Seko, a major Swedish trade union, which has blocked all new electrical connections for new Superchargers. On paper, this made the opening of new Supercharger sites almost impossible.

Despite the blockade, Tesla has continued to bring stations online. In Malmö and Södertälje, new Supercharger locations opened after grid operators E.ON and Telge Nät activated the sites. The operators later stated that the connections had been made in error. 

More recently, however, Tesla adopted a different strategy altogether. Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery, as noted in a Dagens Arbete (DA) report. 

Because the Supercharger station does not rely on a permanent grid connection, Tesla was able to bypass the blocked application process, as noted by Swedish car journalist and YouTuber Peter Esse. He noted that the Arlandastad Supercharger is likely dependent on nearby companies to recharge the batteries, likely through private arrangements.

Eight new charging stalls have been launched in the Arlandastad site so far, which is a fraction of the originally planned 40 chargers for the location. Still, the fact that Tesla Sweden was able to work around the unions’ efforts once more is impressive, especially since Superchargers are used even by non-Tesla EVs.

Esse noted that Tesla’s Megapack workaround is not as easily replicated in other locations. Arlandastad is unique because neighboring operators already have access to grid power, making it possible for Tesla to source electricity indirectly. Still, Esse noted that the unions’ blockades have not affected sales as much.

“Many want Tesla to lose sales due to the union blockades. But you have to remember that sales are falling from 2024, when Tesla sold a record number of cars in Sweden. That year, the unions also had blockades against Tesla. So for Tesla as a charging operator, it is devastating. But for Tesla as a car company, it does not matter in terms of sales volumes. People charge their cars where there is an opportunity, usually at home,” Esse noted.
