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 owners propose interesting theory about Apple CarPlay and EV tax credit

“100%. It’s needed for sales because for many prospective buyers, CarPlay is a nonnegotiable must-have. If they knew how good the Tesla UI is, they wouldn’t think they need CarPlay,” one owner said.

Tesla is reportedly bracing for the integration of Apple’s well-known iOS automotive platform, CarPlay, into its vehicles after the company had avoided it for years.

However, now that it’s here, owners are more than clear that they do not want it, and they have their theories about why it’s on its way. Some believe it might have to do with the EV tax credit, or rather, the loss of it.

Owners are more interested in why Tesla is doing this now, especially considering that so many have been outspoken about the fact that they would not use it in favor of the company’s user interface (UI), which is extremely well done.

After Bloomberg reported that Tesla was working on Apple CarPlay integration, the reactions immediately started pouring in. From my perspective, having used both Apple CarPlay in two previous vehicles and going to Tesla’s in-house UI in my Model Y, both platforms definitely have their advantages.

However, Tesla’s UI just works with its vehicles, as it is intuitive and well-engineered for its cars specifically. Apple CarPlay was always good, but it was buggy at times, which could be attributed to the vehicle and not the software, and not as user-friendly, but that is subjective.

Nevertheless, upon the release of Bloomberg’s report, people immediately challenged the need for it:

Some fans proposed an interesting point: What if Tesla is using CarPlay as a counter to losing the $7,500 EV tax credit? Perhaps it is an interesting way to attract customers who have not owned a Tesla before but are more interested in having a vehicle equipped with CarPlay?

“100%. It’s needed for sales because for many prospective buyers, CarPlay is a nonnegotiable must-have. If they knew how good the Tesla UI is, they wouldn’t think they need CarPlay,” one owner said.

Tesla has made a handful of moves to attract people to its cars after losing the tax credit. This could be a small but potentially mighty strategy that will pull some carbuyers to Tesla, especially now that the Apple CarPlay box is checked.

Investor's Corner

Ron Baron states Tesla and SpaceX are lifetime investments

Baron, one of Tesla’s longest-standing bulls, reiterated that his personal stake in the company remains fully intact even as volatility pressures the broader market.

Billionaire investor Ron Baron says he isn’t touching a single share of his personal Tesla holdings despite the recent selloff in the tech sector. Baron, one of Tesla’s longest-standing bulls, reiterated that his personal stake in the company remains fully intact even as volatility pressures the broader market.

Baron doubles down on Tesla

Speaking on CNBC’s Squawk Box, Baron stated that he is largely unfazed by the market downturn, describing his approach during the selloff as simply “looking” for opportunities. He emphasized that Tesla remains the centerpiece of his long-term strategy, recalling that although Baron Funds once sold 30% of its Tesla position due to client pressure, he personally refused to trim any of his personal holdings.

“We sold 30% for clients. I did not sell personally a single share,” he said. Baron’s exposure highlighted this stance, stating that roughly 40% of his personal net worth is invested in Tesla alone. The legendary investor stated that he has already made about $8 billion from Tesla from an investment of $400 million when he started, and believes that figure could rise fivefold over the next decade as the company scales its technology, manufacturing, and autonomy roadmap.

A lifelong investment

Baron’s commitment extends beyond Tesla. He stated that he also holds about 25% of his personal wealth in SpaceX and another 35% in Baron mutual funds, creating a highly concentrated portfolio built around Elon Musk–led companies. During the interview, Baron revisited a decades-old promise he made to his fund’s board when he sought approval to invest in publicly traded companies.

“I told the board, ‘If you let me invest a certain amount of money, then I will promise that I won’t sell any of my stock. I will be the last person out of the stock,’” he said. “I will not sell a single share of my shares until my clients sold 100% of their shares. … And I don’t expect to sell in my lifetime Tesla or SpaceX.”

Elon Musk reacted sharply to Waymo’s latest milestone after the autonomous driving company revealed its fleet had grown to 2,500 robotaxis across five major U.S. regions. 

As per Musk, the milestone is notable, but the numbers could still be improved.

“Rookie numbers”

Waymo disclosed that its current robotaxi fleet includes 1,000 vehicles in the San Francisco Bay Area, 700 in Los Angeles, 500 in Phoenix, 200 in Austin, and 100 in Atlanta, bringing the total to 2,500 units. 

When industry watcher Sawyer Merritt shared the numbers on X, Musk replied with a two-word jab: “Rookie numbers,” he wrote in a post on X, highlighting Tesla’s intention to challenge and overtake Waymo’s scale with its own Robotaxi fleet.

While Tesla’s Robotaxi network is not yet on Waymo’s scale, Elon Musk has announced a number of aggressive targets for the service. During the third quarter earnings call, he confirmed that the company expects to remove safety drivers from large parts of Austin by year-end, marking the biggest operational step forward for Tesla’s autonomous program to date.

Tesla targets major Robotaxi expansions

Tesla’s Robotaxi pilot remains in its early phases, but Musk recently revealed that major deployments are coming soon. During his appearance on the All-In podcast, Musk said Tesla is pushing to scale its autonomous fleet to 1,000 cars in the Bay Area and 500 cars in Austin by the end of the year.

“We’re scaling up the number of cars to, what happens if you have a thousand cars? Probably we’ll have a thousand cars or more in the Bay Area by the end of this year, probably 500 or more in the greater Austin area,” Musk said.

With just two months left in Q4 2025, Tesla’s autonomous driving teams will face a compressed timeline to hit those targets. Musk, however, has maintained that Robotaxi growth is central to Tesla’s valuation and long-term competitiveness.
