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 registrations in Germany nearly quadruple in October

Published

Tesla’s new vehicle registrations in Germany rose sharply in October, nearly quadrupling from the same month a year earlier. That’s according to data from the KBA, Germany’s federal motor transport authority.

The KBA reported 2,932 Tesla vehicles registered in October, a 290.9 percent year-over-year- increase. For the first ten months of the year, Tesla’s cumulative registrations reached 47,742 units. This number is up 206.1 percent compared with the January-October period of 2025. These gains occurred against a backdrop of strong overall growth in the BEV sector as a whole.

Germany registered 94,086 new BEVs in October, a 79.5 percent rise that brought the BEV share of the passenger car market to 37 percent of the 254,492 total cars registered that month.

Despite the percentage surge, Tesla’s absolute numbers left it with a 1.2 percent share of all new car registrations for October. Chinese competitors did record higher volumes, as BYD registered 5,173 vehicles, a 2 percent share, Leapmotor with 3,661 cars, which equates to 1.4 percent, and Xpeng had a 0.5 percent share.

Year-to-date through October, BYD edged ahead of Tesla with 47,961 registrations versus Tesla’s 47,742.

The October results follow a notably strong September for Tesla in Germany, when it registered 12,552 vehicles, an increase of roughly 269 percent year-over-year and one of its strongest monthly totals on record in the country. That month, the Model Y led all EVs and ranked among the top-selling vehicles of any powertrain.

The figures form part of a broader recovery in Tesla’s European registrations after an extended period of softer demand. While monthly volumes remain subject to typical quarter-end patterns and competitive pressure from both established European brands and rapidly expanding Chinese manufacturers, the year-to-date growth indicates improved traction in Europe’s largest car market.

Tesla’s Gigafactory Berlin-Brandenburg continues to supply the region, positioning the company to capture a share of the expanding German BEV market as overall EV adoptions looks to be accelerating.

Elon Musk hilariously comments on Midterm election results

Published

on

In the early hours of Wednesday following the 2026 midterm elections, Elon Musk took to X with a characteristically irreverent reaction to the results.

“Guess my election-interfering space lasers didn’t work this time,” the Tesla and SpaceX CEO posted, generating hundreds of thousands of likes and widespread attention.

The quip landed after Democrats secured control of both the House and Senate in a sweeping victory. Musk, the largest individual donor of the cycle, had directed an estimated $440–474 million toward Republican candidates and aligned groups—more than any non-candidate in modern history.

Much of the spending targeted Texas, where Musk’s companies have significant operations. There, Democrat Gina Hinojosa defeated incumbent Gov. Greg Abbott, and James Talarico ousted Ken Paxton in the Senate race.

Musk’s “space lasers” joke playfully referenced conspiracy theories that have circulated since the 2024 election, falsely claiming he used Starlink satellites or other technology to influence vote totals. By leaning into the accusation with a shrug emoji, he turned potential criticism into self-deprecating humor:

He followed up with another post observing that “Data centers in space looking pretty appealing right now,” a pointed nod to possible regulatory and infrastructure challenges for data-center projects in Texas under the new Democratic leadership.

Critics quickly highlighted the scale of the spending relative to the outcome. One reply noted that Musk had “dropped half a fucking BILLION on this shit and got dog walked,” underscoring the disconnect between financial outlay and electoral returns. Musk later shared a vintage-style “technical difficulties” image, extending the humorous tone.

The posts arrived as markets reacted: shares of Tesla and SpaceX-related entities dipped in premarket trading amid concerns over heightened scrutiny and shifting state-level politics. Democrats had previously signaled plans to examine Musk’s government ties, DOGE involvement, and business conflicts if they regained congressional majorities.

Musk’s response stands out for its light touch amid high-stakes political setbacks. Rather than offering a detailed defense of his spending or a sober analysis of voter sentiment, he chose sarcasm—consistent with his long-standing style of public communication.

Whether the comments signal a retreat from large-scale political donations ahead of 2028 or simply a momentary shrug remains unclear, but they captured the attention of millions in the immediate aftermath of election night.

SpaceX moves to challenge AT&T, Verizon with Qualcomm-powered 5G

Published

SpaceX has selected Qualcomm Technologies to supply core infrastructure for Starlink Mobile’s planned nationwide terrestrial 5G network in the United States.

Announced on November 4, the multi-year agreement covers radios, baseband units, and commercial-grade Layer 1 software based on Qualcomm’s Dragonwing Cellular Infrastructure platforms, specifically the QRU100 and QDU100:

These will power Massive MIMO radio units featuring 64 transmit and 64 receive paths (64T64R), designed to boost coverage, capacity, and spectral efficiency at scale. Qualcomm has described the pact as its largest 5G deal to date, with deployment across tens of thousands of U.S. cell sites scheduled to begin in 2027.

The terrestrial build-out is meant to complement, not replace, Starlink’s satellite direct-to-cell capabilities. SpaceX has assembled substantial spectrum holdings for this purpose: roughly 65 MHz of mid-band frequencies acquired from EchoStar (including AWS-4 and related bands) and up to 14 MHz of low-band 800 MHz spectrum from Grain Management.

The low-band airwaves improve indoor penetration and range, while mid-band supports higher capacity. SpaceX executives, including President Gwynne Shotwell, have outlined a hybrid architecture in which satellites eliminate outdoor dead zones and terrestrial nodes add capacity where demand is highest.

Earlier comments suggested small cells or femtocells potentially co-located with existing Starlink user terminals on roofs, though later filings also reference more conventional antennas on towers and structures.

The big picture is SpaceX’s bid to become a full-fledged U.S. mobile carrier rather than a satellite partner or dead-zone filler. AT&T, Verizon, and T-Mobile together generate hundreds of billions in annual wireless revenue; Shotwell has said SpaceX expects to win customers by offering superior coverage, including during disasters, through seamless satellite-terrestrial handoff.

Starlink already represents a major share of SpaceX’s revenue and profit following the company’s 2026 IPO. By vertically integrating spectrum, satellite manufacturing, launch capacity, and now ground radio equipment, SpaceX aims to control more of the connectivity stack.

Qualcomm’s involvement also positions the network for future evolution toward AI-native 6G infrastructure, with energy-efficient processing that could improve deployment economics.

Challenges remain: spectrum depth still lags the Big Three, capital costs for tens of thousands of sites will be substantial, and regulatory approvals continue, but the Qualcomm deal marks a concrete step from spectrum accumulation toward operational network build-out.

In short, the partnership accelerates Starlink Mobile’s shift from orbital broadband specialist to hybrid mobile competitor, testing whether a space-based company can reshape terrestrial wireless economics and coverage in the world’s largest market.
