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.

Elon Musk and Trump are closer than ever, and Tesla could be the big winner

Elon Musk sat beside Trump as AI leaders signed a voluntary White House safety accord.

Elon Musk had the seat right next to President Donald Trump on Tuesday as the White House hosted the leaders of America’s biggest artificial intelligence companies for a lunch that ended with a voluntary industry accord on AI safety.

A seating chart Trump posted on Truth Social placed Musk at the president’s left in the East Room, with Nvidia CEO Jensen Huang on his right, according to an Associated Press reporter. Anthropic CEO Dario Amodei, OpenAI President Greg Brockman, Meta’s Mark Zuckerberg, Google’s Sundar Pichai, Microsoft’s Satya Nadella and Amazon founder Jeff Bezos also attended, along with Vice President JD Vance and House Speaker Mike Johnson.

After the lunch, Trump told reporters outside the West Wing that the executives had signed “The White House Accord on Superintelligence: A Joint Commitment on Frontier SI Responsibilities.” Johnson described it as a voluntary statement of principles built on “robust internal controls and layers of internal and external review,” while Zuckerberg said company boards would independently review reports from outside auditors. Trump called the document “morally binding,” said he would name a new AI czar within days, and signed an executive order formally renaming artificial intelligence “super intelligence,” CNBC reported.

Musk was not in the room for Tesla alone. Since SpaceX absorbed xAI, he runs the company behind Grok and one of the largest AI training operations anywhere. On September 25, he said another 220,000 Nvidia GB300 chips would come online at Colossus 2 within a week, with more expected in November and December.

Musk also used the trip to restate his energy ambitions. “SpaceX is aiming together with Tesla to do 200 gigawatts of solar production per year,” he said at an event in Washington. It is the same combined target he laid out that feeds directly into Terafab, the Tesla and SpaceX chip venture that will need enormous amounts of power.

The showing between Musk and Trump has come a long way, since the two had the very public split in mid 2025 after Musk opposed the “Big Beautiful Bill” and left DOGE. They reconciled at Charlie Kirk’s memorial that September, and Trump later called their relationship “good”. Since then, Musk has joined Trump’s China delegation in May and attended last week’s White House state dinner for Chinese President Xi Jinping.

For Tesla, that access to government official could pay dividends. As Teslarati noted in January, federal autonomy rules, NHTSA oversight and a single national standard for driverless vehicles all run through an administration Musk can more easily reach directly as Tesla works to scale Robotaxi and Cybercab beyond Texas.

Tesla Roadster’s new patent preps white-knuckle speeds, keeping it grounded

Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.

The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.

Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.

The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.

The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.

Tesla Roadster event requires restricted airspace, and the FAA obliges

The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.

There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.

These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.

Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.

It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.

Tesla showrooms picked clean ahead of Q3 end as demand looks strong

Tesla (NASDAQ: TSLA) showrooms have been picked clean ahead of the end of the third quarter of the year, as demand looks to be strong and delivery estimates for new vehicles are pushed into late 2026 and early 2027.

Tesla appears to have sold out of many of its Model 3 and Model Y trim levels in the United States, as only the Model Y RWD and Model Y All-Wheel-Drive are available for delivery before the end of the year.

Additionally, many showrooms are either completely empty or void of all but just one demo unit within the buildings themselves in an effort to bolster what could be one of Tesla’s best quarters in vehicle deliveries in recent memory.

Additionally, when I spoke to the guys at Tesla Mechanicsburg two weeks ago, when I returned the Model Y L, their third hauler of the week had just arrived, and every vehicle on it, along with every vehicle in their delivery lot, was accounted for and had a name attached to it for delivery.

Tesla saw a 25 percent increase in deliveries in Q2 compared to the same quarter the year before. The vast majority of the 480,126 units it delivered, 467,762 vehicles to be exact, were the Model 3 and Model Y.

In Q3 2025, Tesla delivered 497,099 vehicles, once again a figure that was dominated by the company’s two mass-market vehicles. Analysts have unusually wide predictions for this quarter, likely because so many firms missed the Q2 delivery figure by such a substantial margin; Wall Street predicted 408,000 cars, while Tesla delivered 480,000.

Goldman Sachs has Tesla slotted for 435,000 deliveries in Q3, while JPMorgan said it anticipates 482,000. The median guess is about 449,000 deliveries for Q3.
