SpaceX ships another huge propellant tank to South Texas BFR test site
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.

- BFR’s booster is at least three times more powerful still than BFS at liftoff. (SpaceX)
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.

Investor's Corner
Tesla analyst’s firm has sold its entire TSLA position: Here’s why
Tesla analyst Gary Black revealed his firm, The Future Fund, has sold their entire $TSLA holding.

Tesla analyst Gary Black of The Future Fund revealed today that his firm has sold its entire $TSLA holding, marking the first time since 2021 that it has not had a position in the company’s stock.
Black has been a skeptic of the company and relatively pessimistic regarding some things many investors would consider catalysts, outlining his concerns and reasoning for selling the shares.
Much of Black’s reasoning concerns Tesla’s price-to-earnings ratio, delivery results and potential delivery figures for the future, and other near-term projects that he does not believe will yield as much value as others perceive.
We will break down each concern of Black’s below:
‘Disconnected from Underlying Fundamentals’
Black says that The Future Fund sold its holdings at $358 per share. The firm’s current price target is at $310, and he says it will remain there based on “our forecast of 2030 Tesla volumes of 5.4m and 2030 Adj EPS of $12.
Main Concern is P/E Ratio
The main concern Black and The Future Fund have is that TSLA “now sells at a 2025 P/E of 188x as earnings estimates continue to fall (-5% in the past week, -40% YTD) driven by weak YTD deliveries, including weak April results.”
Black says he believes quarterly deliveries will decline by 12 percent, and full-year by 10 percent.
This compares to Wall Street’s estimates of a 7 percent decrease for Q2 and a 5 percent year-over-year.
Robotaxi Skepticism
“We believe the risk/reward associated with the Austin robotaxi test remain asymmetrical to the downside,” Black writes in his post on X.
Tesla Robotaxi deemed a total failure by media — even though it hasn’t been released
Many believe the Robotaxi platform could be Tesla’s biggest catalyst moving forward, especially as other automakers do not seem to have even close to as robust a solution to self-driving as Tesla.
Tesla’s Affordable Models
Black says there are concerns the affordable model will be “a stripped-down Model Y priced lower and funded by lower costs rather than a new form factory that expands TAM.”
This is confusing, especially considering the cheaper price tag would expand the total addressable market (TAM) to begin with. The Model Y has been the best-selling vehicle in the world for the past two years.
Tesla still on track to release more affordable models in 1H25
Introducing an even lower-cost model with some missing features would still likely be a significantly more attractive option than a base model ICE vehicle, especially because the value Full Self-Driving provides would make the car more beneficial.
“This increases odds that FY’25 estimates decline further, risking a repeat of 2023-2024, when TSLA reduced EV prices supported by lower costs, and TSLA saw little or no incremental volume growth,” he finishes with.

Tesla gets major upgrade that Apple users will absolutely love
Tesla is unloading a new feature for iPhone users that they will absolutely love.

Tesla is giving its owners who use iPhones and the iOS platform a major upgrade that will make the vehicles more compatible with the current capabilities of Apple devices.
Much to the chagrin of Android users, Apple iPhone users who own Teslas are usually the first to get new features.
However, Tesla is rolling out a new feature to iPhone users that will only be available to them, as Live Update compatibility is now rolling out.
🚨 Tesla Supercharging now will give Live Updates to iOS users
This will help Tesla owners with iPhones track their charging progress while using other apps pic.twitter.com/sjmnjj5BCC
— TESLARATI (@Teslarati) May 28, 2025
Live Updates on the iPhone allow users to track the progress of tasks while using other apps. For example, uploading a post on X can be tracked while using an internet browser, as the Dynamic Island, the small display near the speaker on an iPhone, will show progress.
Tesla will now do this for Supercharging, a new update shows. The Dynamic Island is not the only thing that will monitor the progress of Supercharging, though. Updates will also be visible on the lock screen and as a drop-down notification:

You will need iOS 17.2 or newer to use this feature.
The Supercharging updates will show the current State of Charge (SoC), time remaining, and price of the current session. These notifications will make the charging process easier when you’re not inside your Tesla, as many Superchargers are located in retail settings.
You’ll be able to monitor the price and time remaining with a quick glance at your phone.

Tesla rolls out new crucial safety feature aimed at saving children
Tesla has been working on this child detection feature for several years.

Tesla is finally rolling out a new, crucial safety feature that is aimed at saving children from being left in the car.
Over the past few months, we have reported on a feature Tesla was planning to roll out in its vehicles that would help keep children out of hot cars unattended.
Tesla set to roll out new child safety and navigation features, coding shows
The company has been working on a solution to this problem for several years, as it has been working on an ultrawave sensor that would detect heartbeats instead of movement, as cameras would.
Now, Tesla is implementing the feature in its vehicles with Software Update 2025.14.12, calling it “Child Left Alone Detection.”
The release notes, via Not a Tesla App, show that the vehicle and the Tesla app will both make various attempts to alert the driver of a child in the car:
“If an unattended child is detected, the vehicle will flash the exterior indicator lights, play an alert tone, and send a notification to your Tesla app. This will repeat at regular intervals until you return to your vehicle. Cabin data is processed locally and is not transmitted to Tesla.
This feature is enabled by default. To disable, go to Controls > Safety > Child Left Alone Detection.”
Tesla later said that the feature is currently rolling out to mid-2023 and later Model 3 vehicles in Europe initially, while other models and regions will receive the update in the coming months.
