After a busy few weeks spent attaching Mechazilla’s two rocket-catching arms to a carriage-like backbone, SpaceX has begun the process of installing the integrated structure on Starbase’s ~450 ft (~135m) tall Starship ‘launch tower’.

Once complete, SpaceX will have created a first-of-its-kind launch tower designed to stack and manipulate Starships and Super Heavy boosters in far worse conditions than cranes can tolerate and catch both rocket stages out of mid-air. Referred to internally as ‘chopsticks,’ the giant pair of steel arms will join a third ‘quick disconnect’ (QD) arm tasked with stabilizing Super Heavy during Starship installation and feeding the reusable upper stage power, comms links, and some 1200 tons (~2.65M lb) of propellant.

Together, they will enable SpaceX to attempt Starship’s first orbital test flights and, perhaps one day, help the next-generation rocket launch in almost any weather and achieve unprecedentedly rapid reusability. But first, SpaceX needs to finish installing and rigging the massive structure.

Beginning on August 29th after less than three months of assembly, SpaceX installed Starship’s QD arm on the launch tower. About a month later, the QD arm was mostly finished off with the installation of a claw-like grabber meant to stabilize Super Heavy and is now only missing its namesake quick-disconnect (an actuating device that will connect Starship to the pad and rapidly disconnect at liftoff). Assembly of the last three major components of Mechazilla – a carriage-like structure and two giant arms – began in July and, much like the tower’s QD arm, wrapped up about three months later.

On October 6th, SpaceX began combining those three main parts by flipping the carriage – a bit like a spine and ribcage with ‘skates’ that attach to rails on the launch tower’s legs – vertical and staging it on a temporary support structure. Both ‘chopsticks’ were then flipped into the correct orientation and moved into position with separate cranes for installation on the carriage/backbone. From start to finish, that process took around 9-10 days and culminated with the installation of two giant cylindrical pins with built-in bearings on October 14th and 15th. By the 17th, both cranes had detached from the assembled Mechazilla arms and carriage were, leaving it precisely balanced against the support structure and more or less freestanding.

Just a few days later, after a last-second attempt on October 19th was called off as night fell, SpaceX tried again on the 20th and completed the first step of installing Mechazilla’s catch arms on the launch tower without apparent issue. Likely weighing several hundred tons, Starbase’s largest crane lifted the massive structure up and over an adjacent launch mount and then carefully inched it closer to the tower. Prior to the lift, SpaceX technicians staged 12 ‘skates’ on three of the tower’s four legs – two upper and two lower skates per leg.

Once the carriage was in the right position, workers were able to wrap its upper arms around the tower and began connecting the carriage to those skates with several more large pins. It’s unclear how much progress was made in the hours after the lift but it appears that the carriage has been attached to maybe four or five of six upper skates. Work continued well after nightfall, meaning that it will likely only take a few days to complete all 12 connections. However, even after all skates are installed, the carriage, arms, and skates will still be hanging by crane or winch.

To truly install the structure on the tower, SpaceX will have to finish installing and rigging thousands of feet of steel cable that – via a complex system of pulleys – will connect to powered ‘drawworks’ that will support the carriage and catch arms and lift the assembly up and down the tower like an elevator car. The catch arms and carriage will also need to be mated with a giant ‘cable carrier’ (already staged on the tower) that will connect the structure to ground and control systems.

Tesla Cybertruck gets long-awaited safety feature

Tesla has announced the rollout of its innovative anti-dooring protection feature to the Cybertruck via the 2026.8 software update.

Tesla is rolling out a new and long-awaited feature to the Cybertruck all-electric pickup, and it is a safety addition geared toward pedestrian and cyclist safety, as well as accidents with other vehicles.

Tesla has announced the rollout of its innovative anti-dooring protection feature to the Cybertruck via the 2026.8 software update.

This safety enhancement uses the vehicle’s existing cameras to detect approaching cyclists, pedestrians, or vehicles in the blind spot while parked. Upon attempting to open a door, if a hazard is detected, the system activates: the blind spot indicator light flashes, an audible chime sounds, and the door will not open on the initial button press.

Drivers must wait briefly and press the button again to override, providing crucial seconds to avoid an accident.

The feature, also known as Blind Spot Warning While Parked, comes standard on every new Model 3 and Model Y, and is now extending to the Cybertruck. Leveraging Tesla’s vision-based system without requiring new hardware, it represents a cost-effective software solution that builds on community suggestions dating back to 2018.

This technology addresses the persistent danger of “dooring,” where a driver opens a car door into the path of a passing cyclist or pedestrian.

Tesla implemented this little-known feature to make its cars even safer

Dooring incidents are alarmingly common in urban environments.

According to Chicago data, in 2011 alone, there were 344 reported dooring crashes, accounting for approximately 20 percent of all bicycle crashes in the city, nearly one incident per day.

While numbers have fluctuated (dropping to 11 percent in 2014 before rising again), dooring consistently represents 10-20 percent of bike-related crashes in major cities.

A national analysis of emergency department data estimates over 17,000 dooring-related injuries treated in the U.S. over a decade, with many involving fractures, contusions, and head trauma, particularly affecting upper extremities.

By automatically intervening, Tesla’s system not only protects vulnerable road users but also safeguards its owners from potential liability and enhances overall road safety.

As cities promote cycling for sustainable transport, features like this demonstrate how advanced driver assistance and camera systems can evolve beyond highway driving to everyday urban scenarios.

Enthusiastic responses on social media highlight appreciation for the proactive safety measure, with some calling for broader rollout to older models where hardware permits. Tesla continues to push the boundaries of vehicle safety through over-the-air updates, making its fleet smarter and safer over time.

Tesla Roadster is ‘sorcery and magic’ and might be worth the wait, Uber founder says

Perhaps the wait will be worth it, especially according to Uber founder Travis Kalanick, who recently teased the Roadster’s potential capabilities based on what he has heard from internal Tesla sources.

Tesla is planning to unveil the Roadster in late April after years of waiting. But the wait might be worth it, according to Travis Kalanick, the founder of Uber, who recently shed some light on his expectations for the all-electric supercar.

We all know the Roadster is supposed to have some serious capability. CEO Elon Musk has said on numerous occasions that the Roadster will be unlike anything else ever produced. It might go from 0-60 MPH in about a second, it might hover, it might have SpaceX cold gas thrusters.

However, the constant delays in the Roadster program and its unveiling event continue to send Tesla fans into confusion because they’re just not sure when, or if, they’ll ever see the finished product.

Perhaps the wait will be worth it, especially according to Uber founder Travis Kalanick, who recently teased the Roadster’s potential capabilities based on what he has heard from internal Tesla sources.

Kalanick said on X:

Musk has said this vehicle is not going to be geared for safety, and that, “If safety is your number one goal, do not buy the Roadster.”

There has been so much hype regarding the Roadster that it is hard to believe the company could not come through on some kind of crazy features for the vehicle.

Elon Musk just dropped a huge detail on the Tesla Roadster

However, the latest delay that Tesla put on the unveiling event is definitely eye-opening, especially considering it is the latest in a series of pushbacks the company has put on the vehicle for the past several years.

Tesla has made several jumps in the Roadster project over the past few months, as it has ramped up hiring for the vehicle and also applied for a patent for a new seat design.

The car has been a back-burner project for Tesla, as it has been focusing primarily on autonomy and the rollout of Robotaxi and Cybercab. Additionally, its other vehicle projects, like the Model 3 and Model Y refreshes, took precedence.

Tesla still plans to unveil the Roadster next month, so we can hope the company can stick to this timeframe.

Elon Musk clarifies viral Tesla Cybertruck accident with driver logs

Musk has come out to say that the driver logs have already shown that the driver “disengaged Autopilot four seconds before crashing,” in a post on X.

Tesla CEO Elon Musk has clarified some details regarding the viral Tesla Cybertruck accident with company driver logs, which show various metrics at the time of an incident.

The logs have been used in the past to pull responsibility off of Tesla when the automaker’s Full Self-Driving (Supervised) or Autopilot platforms are blamed for a collision or accident. It appears this will be no different.

On Tuesday, a video of a Cybertruck crashing into an overpass barrier in August 2025 was shared by Fox Business in a story that reported a woman was suing the automaker for $1 million in a liability and negligence case.

In the suit, Justine Saint Amour said that, “Something terrifying happened, without warning, the vehicle attempted to drive straight off an overpass.” Her attorney, Bob Hilliard, said Amour “tried to take control, but crashed into the barrier and was seriously injured (mostly her shoulder, neck, and back).”

The Tesla Model Y is leading China’s electric SUV segment by a wide margin

Tesla vehicle crashes are widely popular to report by mainstream media outlets because of the sensationalism of the event. Oftentimes, these outlets will include Tesla in the headline, especially because it will pique the interest of the masses, as most who read the story are waiting to see the claim that Autopilot or Full Self-Driving was the culprit of the accident.

However, Tesla has access to the logs of every vehicle in its fleet, which will show the various metrics, like whether either FSD or Autopilot was active, if the accelerator was pressed, the speed, and other important factors.

Musk has come out to say that the driver logs have already shown that the driver “disengaged Autopilot four seconds before crashing,” in a post on X.

If the logs do show this, which Tesla will likely have to prove in court, the real question would be why did the Amour disengage the suite?

Tesla’s Full Self-Driving suite is still not fully autonomous, meaning the driver cannot pull attention away from the road and must be ready to take over the vehicle at all times.

It will be interesting to see how this particular case pans out, especially considering the clip that was released by the law firm starts at about four seconds before the collision. Tesla logs have dispelled media reports in the past that have accused the company’s suite of being responsible for an accident, so there will be some major attention on what is proven in this particular case.
