SpaceX Super Heavy tank prototype survives crush testing

Published

on

A tank prototype similar to SpaceX’s next-generation Super Heavy rocket booster has survived a series of tests that repeatedly attempted to destroy it.

Known as Booster 7.1 or B7.1, the tank is the latest in a long line of ‘test tanks’ designed to verify the performance of Starship and Super Heavy and qualify new designs and manufacturing techniques without risking an entire upper stage or booster. In general, that means that test tanks are as minimal as possible and much shorter than either Starship stage, but they’re also assembled out of nine-meter-wide (30 ft) steel barrels and domes almost identical to the sections that make up Starship and Super Heavy.

For most of the duration of SpaceX’s steel Starship program, ‘test tank’ work has followed a fairly consistent and linear development path, where tanks were used to verify design changes before those changes were implemented on more expensive prototypes. B7.1 firmly ignored that norm.

While it’s not an exact match, the tank – built out of two stacked rings and dome sections and measuring about 11 meters (~36 ft) tall – has a Super Heavy thrust structure (where Raptor engines would attach) and external stiffeners known as stringers that are (mostly) exclusive to Starship boosters.

As its name suggests, B7.1 shares many of the significant design changes that SpaceX had already implemented on Super Heavy Booster 7 (B7). The company began testing B7 months before B7.1, subjecting the full-size booster to multiple cryogenic proof tests and Raptor thrust simulation testing to qualify its new thrust ‘puck’ and several other structural changes. SpaceX began testing B7.1 in late June, shortly before Super Heavy Booster 7 was damaged by an unplanned explosion that halted its first Raptor engine test campaign. B7.1 testing then restarted in mid-July and was completed by the end of the month.

For unknown reasons, SpaceX’s decision to build and test Booster 7 before B7.1 meant that any significant issues discovered during subsequent B7.1 testing could disqualify the booster for flight testing, potentially wasting the months of work and tens of millions of dollars already invested in the prototype. Ultimately, though, B7.1 appeared to sail through multiple cryogenic proofs and crush tests without any catastrophic issues. Only on the last crush test did any part of the test tank finally give way, and the resulting damage was minor.

B7.1’s testing made use of a relatively new two-piece stand. The tank was first installed on a sturdy base using clamps similar to those on the Starbase orbital launch site’s (OLS) launch mount. Then, a hat-like structure was placed on top of the tank, resting on the surface that a Starship upper stage would sit on during launch. Massive ropes were finally dropped down to attach to hydraulic cylinders on the base. Once B7.1 was loaded with benign cryogenic liquid nitrogen (LN2), replicating most of the thermal and mechanical stresses of real oxygen/methane propellant, the hydraulic cylinders retracted, pulling the cap down to evenly exert massive crushing forces down the vertical axis of the test tank. Simultaneously, additional rams installed underneath B7.1 may have simulated the thrust of 13 central Raptor engines.

It’s unclear what exactly SpaceX was testing. The goal of the test could have been as simple as verifying that Super Heavy Booster 7 can withstand the weight of a fully-fueled Starship (~1350 tons / ~3M lb) sitting on top of it. It could have also been used to simulate an entire orbital launch from Super Heavy’s perspective, replicating many of the forces Starship boosters will experience between liftoff and landing. Given that Booster 7’s upgraded thrust puck had already made it through stress testing, B7.1 didn’t have much to add there, but it may have been useful for estimating the compressive strength of the current Super Heavy booster design.

Regardless of what B7.1 did or didn’t prove, it did so with very little drama. After four long days of testing, at least two of which involved attempting to crush the tank, the only truly noteworthy visual event was evidence of a slight buckle near the top of the tank during its last crush test. A few days later, with the test stand ‘cap’ removed, B7.1 survived one final test in which SpaceX likely attempted to pressurize the tank until it burst. Instead, the tank didn’t so much as develop a leak, reiterating – contrary to their occasional tin-can-like appearances – just how sturdy Starship and Super Heavy really are.

With nothing more to give, SpaceX will likely scrap B7.1. Meanwhile, Super Heavy Booster 7 remains stuck inside one of SpaceX’s Starbase assembly bays after being forced back to the factory by unintentionally explosive testing. The fate of that booster is unclear but SpaceX has removed all or most of its 33 Raptor engines over the last few weeks while simultaneously expediting work on Booster 8, which may ultimately take B7’s place.

Tesla removes Autopilot as standard, receives criticism online

The move leaves only Traffic Aware Cruise Control as standard equipment on new Tesla orders.

Tesla removed its basic Autopilot package as a standard feature in the United States. The move leaves only Traffic Aware Cruise Control as standard equipment on new Tesla orders, and shifts the company’s strategy towards paid Full Self-Driving subscriptions.

Tesla removes Autopilot

As per observations from the electric vehicle community on social media, Tesla no longer lists Autopilot as standard in its vehicles in the U.S. This suggests that features such as lane-centering and Autosteer have been removed as standard equipment. Previously, most Tesla vehicles came with Autopilot by default, which offers Traffic-Aware Cruise Control and Autosteer.

The change resulted in backlash from some Tesla owners and EV observers, particularly as competing automakers, including mainstream players like Toyota, offer features like lane-centering as standard on many models, including budget vehicles.

That being said, the removal of Autopilot suggests that Tesla is concentrating its autonomy roadmap around FSD subscriptions rather than bundled driver-assistance features. It would be interesting to see how Tesla manages its vehicles’ standard safety features, as it seems out of character for Tesla to make its cars less safe over time. 

Musk announces FSD price increases

Following the Autopilot changes, Elon Musk stated on X that Tesla is planning to raise subscription prices for FSD as its capabilities improve. In a post on X, Musk stated that the current $99-per-month price for supervised FSD would increase over time, especially as the system itself becomes more robust.

“I should also mention that the $99/month for supervised FSD will rise as FSD’s capabilities improve. The massive value jump is when you can be on your phone or sleeping for the entire ride (Unsupervised FSD),” Musk wrote. 

At the time of his recent post, Tesla still offers FSD as a one-time purchase for $8,000, but Elon Musk has confirmed that this option will be discontinued on February 14, leaving subscriptions as the only way to access the system.

Tesla begins Cybertruck deliveries in a new region for the first time

Tesla has initiated Cybertruck deliveries in a new region for the first time, as the all-electric pickup has officially made its way to the United Arab Emirates, marking the newest territory to receive the polarizing truck.

Tesla launched orders for the Cybertruck in the Middle East back in September 2025, just months after the company confirmed that it planned to launch the pickup in the region, which happened in April.

I took a Tesla Cybertruck weekend Demo Drive – Here’s what I learned

By early October, Tesla launched the Cybertruck configurator in the United Arab Emirates, Qatar, and Saudi Arabia, with pricing starting at around AED 404,900, or about $110,000 for the Dual Motor configuration.

This decision positioned the Gulf states as key early international markets, and Tesla was hoping to get the Cybertruck outside of North America for the first time, as it has still been tough to launch in other popular EV markets, like Europe and Asia.

By late 2025, Tesla had pushed delivery timelines slightly and aimed for an early 2026 delivery launch in the Middle East. The first official customer deliveries started this month, and a notable handover event occurred in Dubai’s Al Marmoom desert area, featuring a light and fire show.

Around 63 Cybertrucks made their way to customers during the event:

As of this month, the Cybertruck still remains available for configuration on Tesla’s websites for the UAE, Saudi Arabia, Qatar, and other Middle Eastern countries like Jordan and Israel. Deliveries are rolling out progressively, with the UAE leading as the first to see hands-on customer events.

In other markets, most notably Europe, there are still plenty of regulatory hurdles that Tesla is hoping to work through, but they may never be resolved. The issues come from the unique design features that conflict with the European Union’s (EU) stringent safety standards.

These standards include pedestrian protection regulations, which require vehicles to minimize injury risks in collisions. However, the Cybertruck features sharp edges and an ultra-hard stainless steel exoskeleton, and its rigid structure is seen as non-compliant with the EU’s list of preferred designs.

The vehicle’s gross weight is also above the 3.5-tonne threshold for standard vehicles, which has prompted Tesla to consider a more compact design. However, the company’s focus on autonomy and Robotaxi has likely pushed that out of the realm of possibility.

For now, Tesla will work with the governments that want it to succeed in their region, and the Middle East has been a great partner to the company with the launch of the Cybertruck.

BREAKING: Tesla launches public Robotaxi rides in Austin with no Safety Monitor

Published

on

Tesla has officially launched public Robotaxi rides in Austin, Texas, without a Safety Monitor in the vehicle, marking the first time the company has removed anyone from the vehicle other than the rider.

The Safety Monitor has been present in Tesla Robotaxis in Austin since its launch last June, maintaining safety for passengers and other vehicles, and was placed in the passenger’s seat.

Tesla planned to remove the Safety Monitor at the end of 2025, but it was not quite ready to do so. Now, in January, riders are officially reporting that they are able to hail a ride from a Model Y Robotaxi without anyone in the vehicle:

Tesla started testing this internally late last year and had several employees show that they were riding in the vehicle without anyone else there to intervene in case of an emergency.

Tesla has now expanded that program to the public. It is not active in the entire fleet, but there are a “few unsupervised vehicles mixed in with the broader robotaxi fleet with safety monitors,” Ashok Elluswamy said:

The Robotaxi program also operates in the California Bay Area, where the fleet is much larger, but Safety Monitors are placed in the driver’s seat and utilize Full Self-Driving, so it is essentially the same as an Uber driver using a Tesla with FSD.

In Austin, the removal of Safety Monitors marks a substantial achievement for Tesla moving forward. Now that it has enough confidence to remove Safety Monitors from Robotaxis altogether, there are nearly unlimited options for the company in terms of expansion.

While it is hoping to launch the ride-hailing service in more cities across the U.S. this year, this is a much larger development than expansion, at least for now, as it is the first time it is performing driverless rides in Robotaxi anywhere in the world for the public to enjoy.
