Captured by NASASpaceflight.com forum user “bocachicagal”, the second of several massive liquid methane tanks has arrived at SpaceX’s prospective Boca Chica, Texas facilities, to be dedicated to integrated testing of BFR’s spaceship/upper stage.

If there was any doubt beforehand, the arrival of a second ~100,000 gallon vacuum-insulated tank all but guarantees that SpaceX is planning a major campaign of BFR spaceship testing in South Texas – with as much as 200,000 gallons of storage capacity in those two tanks alone, SpaceX could easily top off two Falcon 9’s with liquid oxygen and still have more than 100 tons left over.

Per NASASpaceflight.com’s forums, it appears that this newest tank arrived at the site sometime yesterday or the day before. Thanks to the fundamental properties of BFR’s planned liquid methane and oxygen fuel and oxidizer, aspects of basic ground support infrastructure may actually be a significant improvement over Falcon 9’s refined kerosene (RP-1) and liquid oxygen, and dramatically superior (at least in a logistical and practical sense) to hydrogen/oxygen, a popular choice for many rockets.

In terms of volume and density, oxygen is about 2.5x denser than methane but optimally combusts at a ratio of roughly 3.5 parts oxygen to 1 part methane (3.5:1), with SpaceX likely to operate the Raptor engine closer to 3.8:1. This means that – despite their major density differences – BFR’s oxygen and methane tanks will ultimately end up very similarly sized to hold ~230t of liquid methane and ~860t of liquid oxygen (2017 BFR numbers).

Testing giant rockets: it’s not easy

As it relates to SpaceX’s South Texas propellant infrastructure, this likely means that a minimum of four large vacuum-insulated tanks will be needed to fully fuel a BFR spaceship (BFS), two for oxygen (~800t) and two for methane (~300t). Depending on how SpaceX has structured its BFR infrastructure acquisitions, the two large tanks now present in Boca Chica could be more than enough to support a wide range of spaceship hop tests. A full load of fuel is almost certainly unnecessary – if not outright implausible – for BFS hop testing: with a full load of ~1100t of fuel and the spaceship’s total mass around ~1250t, all seven planned Raptor engines would need to be installed and operating near full thrust (~1400t, 14,000 kN) to lift the ship off the ground.

For context, Falcon 9’s first stage produces a maximum thrust of roughly 7,600 kN at liftoff, while Falcon Heavy triples that figure to ~22,800 kN.  The spaceship/upper stage of BFR alone thus produces nearly two times as much thrust as an entire Falcon 9 at full throttle and as much as fourteen times as much thrust as Falcon 9 and Heavy’s upper stage, statistics that properly illustrate just how extraordinarily powerful BFR is when compared with the rockets SpaceX currently operates. BFR’s booster (BFB) is even wilder, featuring ~3.5 times as many Raptors and thus ~3.5 times as much thrust as the spaceship/upper stage.

As a result of the sheer power of just the spaceship alone, SpaceX may have to move directly to a style of launch pad closer to that used by Falcon 9 and Heavy rather than the spartan concrete slab used for Falcon 9’s Grasshopper testing. In this case, the rocket would be mounted some distance from the ground to minimize acoustic loads on the vehicle’s after and would likely include a water deluge system to further deaden thermal and acoustic energy while also minimizing damage to the concrete and metal structures that launch and landing pads are built out of.

 

Above all else, the presence of not one but two huge ~100,000-gallon vacuum-insulated tanks at SpaceX’s Boca Chica facilities all but guarantees that the company intends to situate a serious campaign of BFR tests there, likely including the integrated spaceship hop tests both Elon Musk and Gwynne Shotwell have explicitly mentioned in recent months. Put simply, SpaceX has no other reason to be bringing massive cryogenic propellant tanks to South Texas – the company has plenty of space at any one of its three large launch complexes (not to mention McGregor) if it wanted to store those tanks elsewhere, and those three facilities already have operational propellant storage and loading infrastructure for Falcon 9 and Heavy launches.

If more massive tanks continue to arrive or if it becomes clear that the two similar tanks present or solely meant for LOX or methane, the scale of SpaceX’s intentions in South Texas will become increasingly clearer.

Tesla CEO Elon Musk hits back at drug use claims, calls publications ‘hypocrites’

Elon Musk showed a clean drug test, dispelling any rumors of drug use that came from unfounded reports from two large media outlets.

Tesla CEO Elon Musk has responded to a report from the Wall Street Journal and the New York Times, as both publications claimed he was abusing drugs while being involved with President Trump on both the campaign trail and while he was active within the administration after the election.

A bombshell report from the New York Times, published in late May, stated that Musk was regularly using things like ketamine, ecstasy, and psychedelic mushrooms, and also stimulants like Adderall, during his time within the Trump administration.

The reports cited inside sources who claimed the Tesla and SpaceX frontman was using substances during his time with the government.

However, Musk published the results of a recent drug test performed at Fastest Labs of South Austin. They showed ‘Negative’ results across the board:

Musk was not done there.

He went on to say the New York Times “lies as easy as breathing. It’s normal for them.” He also said both the Times and Wall Street Journal reporters should also publish their own drug test results, stating, “They won’t, because those hypocrites are guilty as sin.”

Musk said years ago that he received ketamine prescriptions from doctors to treat depression. He said he had it “years ago and said so on X, so this is not even news.” He also said that ketamine “helps for getting out of dark mental holes, but haven’t taken it since then.”

Tesla fans and Musk enthusiasts have joked for days now that, if Musk were to be on drugs, other CEOs should also do them, considering his persistence on work-related projects, long hours, and commitment to his job.

Musk has now proven that there has been no drug use with this test, and it seems as if the reports could have some sort of legal impact, although he has not said he will take any action.

Tesla’s Grok integration will be more realistic with this cool feature

Tesla is preparing Grok for its first integration into vehicles, but it’s making it more robust than ever, firmware shows.

Tesla has not yet integrated the AI assistant Grok into its vehicles, but when it does, it will be even more realistic with a new feature that firmware coding shows.

CEO Elon Musk teased a few months back that Grok would be making its way into vehicles in the near future. The implementation has not yet occurred, but we are confident it will be rolling out soon, especially as Tesla has its sights set on a near-term rollout of the Robotaxi platform.

Tesla’s vehicles expected to get Grok voice assistant—but when?

Grok will enable AI assistance for drivers who are both manually operating Tesla vehicles or using the company’s Full Self-Driving suite. It has been widely popular and extremely useful for users on X, Musk’s social media platform.

However, Tesla hacker green has revealed through firmware that the company is planning to roll out Grok into vehicles with personalities, giving it an even more realistic tone that is totally customizable and catered to whatever the driver wants.

There are also a handful of kids’ versions that will do things like tell stories or play trivia:

The true capabilities of Grok are nearly limitless. Back in January, Musk said on a livestream on X that, “You’ll be able to talk to your Tesla and ask for anything.”

Grok appears to only be available on AMD-based vehicles, according to other things green found in the firmware. This means that Intel-based Teslas, which are usually older models, will not enable Grok support for right now.

Tesla dominates Cars.com’s Made in America Index with clean sweep

Tesla continues to dominate Cars.com’s Made in America Index with a clean sweep of the Top 4 spots.

Tesla has dominated the Cars.com Made-in-America Index with a clean sweep of the top four spots. All four Tesla vehicles that were eligible for the analysis placed in the top four.

The Model 3 overtook the Model Y for first place this year. The all-electric crossover was first in 2024, but the Model 3 managed to overtake its sibling vehicle to claim the top spot in 2025. The Model Y took second, while the Model S took third, and the Model X took fourth.

This is an improvement from last year, as the Model Y took first, but the Model S and Model X placed fourth and ninth, respectively. The Model 3 was not in the Top 10 in 2024.

“Tesla continues to lead, claiming the top four spots and showcasing its commitment to domestic production. About 25% of the more than 400 vehicles on sale in the U.S. made this year’s AMI, and whether a vehicle is No. 1 or No.99, it contributes to the U.S. economy,” Patrick Masterson, lead researcher for the program, said.

More than 400 vehicles were analyzed for this year’s study, with Cars.com officially ranking 117 of them. There were two other EVs in the Top 10, as the Kia EV6 took sixth place, and the Volkswagen ID.4 finished in tenth.

This year’s study reflected major geographic and strategic shifts across the automotive industry. Of the 117 vehicles ranked in the program, they were produced at 36 domestic factories, leaving only 11 total factories that did not yield a car on the list. There are 47 assembly plants in operation in the U.S.

However, there still has not been a vehicle to quite reach the 100 percent domestic parts content, something that is extremely elusive. Masterson says the global supply chain is still extremely crucial to even the most American-built cars on the market.

The average domestic parts content of the Top 10 cars was 83.4 percent in 2006, but that number has shrunk to 70.3 percent in this year’s rankings.

Some might wonder where cars like the Tesla Cybertruck or Rivian R1T are on the list. However, these vehicles did not qualify because the study only considers cars under a gross weight of 8,500 pounds.
