SpaceX stress-tests Starship-catching arms with giant water balloons

Published

SpaceX has begun testing Starbase’s rocket-catching arms with ballast to simulate the weight of Starship and Super Heavy.

SpaceX started the process of proof testing those arms about a week ago, beginning with some basic calibration work. Together, the three arms and launch tower amount to a giant custom-built robot that SpaceX CEO Elon Musk has deemed “Mechazilla.” Controlled with a complex system of hydraulic and electromechanical actuators spread throughout each structure, SpaceX must calibrate all of those devices to enable the full range of motion the arms are meant to be capable of. To do so, SpaceX appeared to actuate both catch arms (also known as “chopsticks”) as far as they were able to move on January 4th, producing data that could be fed back into the system’s control software to properly set limits of motion.

A handful of days later, arm testing continued, with SpaceX lifting the carriage higher than it had traveled before and demonstrating more complex longitudinal movements that required synchronized motion of both arms. On January 9th, SpaceX performed the most ambitious arm testing yet, nearly lifting the arms to the top of their ~140 meter (~460 ft) tall launch tower backbone to simulate the range of vertical motion required to lift and stack Starship and Super Heavy.

SpaceX also installed a temporary frame meant to simulate a Starship or Super Heavy booster, foreshadowing additional testing planned in the coming days. That jig upped the stakes for the longitudinal actuation portion of January 9th’s testing, as anything less than the precise, synchronized movement of both arms could have caused the heavy steel frame to fall hundreds of feet onto a range of equipment and structures directly below it. Thankfully, the arms performed well and returned to their resting position without issue.

On January 11th, SpaceX proceeded to install six ‘water bags’ – three to a side – on the Starship simulator frame. Amounting to giant, heavy-duty water balloons, those bags are routinely used to stress-test large structures and devices by simulating payloads that might be too expensive or inconvenient to use solely for testing purposes. With those seemingly empty bags attached, SpaceX proceeded to move the catch arms up and down the full length of the launch tower at record speed, taking about seven minutes to climb and descend ~120 meters (~400 ft) – averaging a brisk 0.6 mph or 1 km/h.

On January 12th, SpaceX filled the balls with water, producing some… interesting… visuals. Ridiculous appearances aside, the six bags SpaceX chose to use could be 20, 35, or 50-ton variants, meaning that all six could weigh anywhere from 120 to 300 tons (264,000-660,000 lb) if fully filled. In other words, perfect for simulating the dry masses of Starship (roughly 80-120 tons) and Super Heavy (150-200+ tons).

SpaceX did appear to fully fill around four of the six bags and partially filled the other two, causing the whole arm structure to visibly sag during the fill process as the weight of the ballast stretched the several-inch-thick steel cable holding the whole device aloft. In the late afternoon, the laden arms lifted around 10-20 meters and rotated left and right, partially demonstrating the process of rotating a lifted Starship or Super Heavy into position for stacking or launch mount installation. They were never lifted high enough to truly demonstrate that ability, though, and were lowered back to the ground soon after.

As of 10pm CST, January 12th, the water bags appear to have been fully drained after their first excursion. It’s likely that load-testing will continue over the next several days or weeks – SpaceX may just want to avoid leaving the arms fully loaded overnight.

Tesla begins production of new Model Y trim at Giga Berlin

Tesla announced on Monday that its Model Y Standard configuration was officially being built at Giga Berlin, less than one month after the company officially announced the configuration early last month.

Tesla has begun production of the new Model Y trim at Gigafactory Berlin, the company’s production plant in Germany.

Tesla announced on Monday that its Model Y Standard configuration was officially being built at Giga Berlin, less than one month after the company officially announced the configuration early last month.

On October 7, Tesla announced the launch of the Model 3 and Model Y Standard trim levels, its answer to the call for affordable EVs within its lineup and its response to the loss of the $7,500 electric vehicle tax credit.

On October 3, Tesla started production of the vehicles in Germany:

The Standard iteration of the Model Y is void of many of the more premium features that are available in the Rear-Wheel-Drive, All-Wheel-Drive, and Performance trims of the vehicle are equipped with.

A few of the features of the Model Y Standard are:

  • Single Motor configuration
  • No rear touchscreen
  • Textile seats with vegan leather, instead of all vegan leather
  • 320-mile range
  • No glass roof

The launch of the Model Y Standard was truly a move to help Tesla get vehicles into the sub-$40,000 price point, and although many consumers were hoping to see the company get closer to $30,000 with these cars, this is a great starting point.

Deliveries in the United States have already started, and it seems it will be a vehicle that will do one of two things: either push some consumers to finally make the jump to Tesla, or it will give car buyers another reason to buy the Premium trims, as they may feel the lack of features is not a good enough deal.

This is something we saw with the Cybertruck’s Rear-Wheel-Drive configuration, which launched last year and ended up being more of the latter option listed above.

The Tesla Model Y Standard is actually a great deal in Europe

It was only a $10,000 discount from the All-Wheel-Drive Cybertruck, but it also did not have adaptive air suspension, premium interiors, or the powered tonneau cover, which many people felt was too much of a sacrifice.

The Rear-Wheel-Drive Cybertruck was discontinued only a few months later.

It does not seem as if this is the case with the Model Y Standard, which already seems to be an attractive option to some buyers.

Tesla has officially begun the wide rollout of Full Self-Driving (Supervised) v14 to the Cybertruck about a month after the company started rolling it out to other vehicles in the fleet.

On Monday, Tesla officially started rolling out v14.1.5 to Cybertruck owners, the first FSD v14 rollout for owners of the all-electric pickup.

Owners have been anxiously waiting for Tesla to begin the wide release of v14 to Cybertruck, as the company said it would refine the suite for the vehicle.

Tesla has finally started rolling out to many owners, who are reporting that their Cybertrucks are downloading Software Update 2025.38.8.5, which contains FSD v14.1.5:

Tesla has to be more cautious with rolling out FSD on the Cybertruck than on other vehicles for a few reasons. Initially, the Cybertruck utilizes an all-wheel steering system that turns differently than the S3XY lineup. This creates a challenge for the Tesla AI team as they have to cater to this specific maneuvering change.

Additionally, the Cybertruck is much larger, and the exterior cameras responsible for seeing the vehicle’s surroundings are placed differently than those of the other vehicles.

This requires additional calibration to ensure safety.

The full release notes for Full Self-Driving v14.1.5 are as follows:

  • Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, in a Parking Garage, or at the Curbside.
  • Added handling to pull over or yield for emergency vehicles (e.g. police cars, fire trucks, ambulances).
  • Added navigation and routing into the vision-based neural network for real-time handling of blocked roads and detours.
  • Added additional Speed Profile to further customize driving style preference.
  • Improved handling for static and dynamic gates.
  • Improved offsetting for road debris (e.g. tires, tree branches, boxes).
  • Improve handling of several scenarios including: unprotected turns, lane changes, vehicle cut-ins, and school buses.
  • Improved FSD’s ability to manage system faults and recover smoothly from degraded operation for enhanced reliability.
  • Added alerting for residue build-up on interior windshield that may impact front camera visibility. If affected, visit Service for cleaning!

Elon Musk shuts down Tesla ‘AMG’ division speculation: ‘Focus is autonomy’

“I think it’s best to leave that to the custom shops. Tesla’s focus is autonomous cars, building futuristic autonomous cars. We want the future to look like the future.”

Tesla CEO Elon Musk was asked by Joe Rogan late last week whether the company would ever consider establishing an “AMG division” like Mercedes-Benz has established for powerful, race-inspired vehicles.

However, Musk turned down any talk of that, highlighting that the company is laser-focused on autonomous vehicles, seemingly hinting that any distraction from autonomy would be a detriment to the future.

Rogan drives a Tesla Model S himself, but it is not your run-of-the-mill all-electric sedan. Already outfitted with the Plaid powertrain that Tesla developed, Rogan took his vehicle to Unplugged Performance for a true performance outfitting.

The vehicle is completely overhauled with performance parts and seats. Known as the Model S-APEX, Rogan took delivery of it from Unplugged in January.

Rogan asked Musk on Friday during his most recent appearance on the Joe Rogan Experience podcast whether Tesla would ever establish an “AMG division” that would focus on catering Teslas to performance-based standards.

Musk said:

“I think it’s best to leave that to the custom shops. Tesla’s focus is autonomous cars, building futuristic autonomous cars. We want the future to look like the future.”

Tesla fans have said for years that the company should consider acquiring Unplugged Performance and its Upfit Tesla division, which recently outfitted the Las Vegas Metropolitan Police Department’s fleet of Cybertruck cruisers.

However, it seems Tesla will keep things separate. Musk is primarily focused on autonomy, which will drive the technology forward and drive shareholder growth. Something like an outfitter for performance would be a cool thing for the owners who have the interest and the money.

It’s not a tremendous revenue driver or anything that would contribute to the financial state of the company. Mercedes-Benz, for example, is more accessible for consumers as it sold over 140,000 units from its AMG brand in 2024.

It helps with driving revenue higher by as much as 15 percent compared to similar models that are not AMGs. However, would Tesla see this much of a benefit? Likely not, because the Performance trim already caters to many owners.
