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.

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 has started to deploy the 2026 Summer Update to owners across its fleet, and among the biggest changes are improvements to Navigation, a new startup animation for the Model 3 and Model Y, Caraoke scoring, and new capabilities for Grok.
As the update has started making its way to some cars, we can now see a few of the features operating in real-time. We will show you what some of the new features look like in this article, along with some additional details on what changed.
Not all of the new features in the 2026 Summer Update have quite made an appearance, but some of them have, so we’ll show those here:
New Animation Screen for 3/Y
Tesla is rolling out a new startup animation for Tesla Model 3 and Model Y owners. This is present in Launch Edition and Performance Model 3 and Model Y, but other trim levels do not have anything like this.

Owners can adjust the color associated with the startup animation to suit their preferences. It is a surprise that more automakers do not focus on this animation for their vehicles; it can be a great first impression piece and make the car immediately feel more luxurious.
Tesla has included this on more premium trims, but it is nice to see it on the Model 3 and Model Y.
Grok Improvements
Grok can now adjust more things in the car outside of the Navigation system. Now, drivers can adjust anything from climate to driving settings by simply speaking to the AI assistant in the car:

You don’t even have to push a button, either. Instead, you can just say “Hey, Grok,” if you have it enabled. That feature rolled out with the 2026 Spring Update just a few months back.
-
This is a great feature, especially pertinent for the Robotaxi platform, as there will be no buttons inside the Cybercab when it eventually starts giving rides to the public. It also broadens Grok’s capabilities, which were relatively limited in terms of vehicle setting adjustments beforehand.
Tesla briefly offered one Robotaxi part in its Parts Catalog for your personal car, only to remove it just a short time after it was first noticed.
Tesla’s Robotaxi camera washer apparatus was briefly available for purchase on the company’s Online Parts Catalog. The camera washer was first noticed on Model Y Robotaxi vehicles about six months ago in Austin.

First noticed by Not a Tesla App, the Camera Washer entries appeared for the new “Juniper” Model Y under a category called “Halo,” which has also now disappeared. Interestingly, Halo probably is related to Tesla’s internal “Project Halo,” which was a project that aimed to retrofit customer-owned Model Ys into functional Robotaxis.
This hardware addition would likely be required for the vehicle to operate as a Robotaxi, as the Camera Washer seems to be a non-negotiable part of the vision-based system Tesla utilizes for self-driving efforts.
However, this part has since been removed and is no longer visible on the EPC.
-
Now the true question lingers: Why would Tesla add this Camera Washer to the Model Y parts catalog? Is it planning to make it available for owners to utilize on their own cars for personal use, or will it become a prerequisite for Robotaxi operation in customer-owned cars?
While discussing the upgrade options for Hardware 3 vehicles during the Q1 Earnings Call, Tesla CEO Elon Musk had said that the company could establish small, satellite shops that would upgrade cameras and self-driving computers. Perhaps this same strategy could be utilized for vehicles that want to be included in Robotaxi but do not have the correct hardware.
AI4 is currently represented as capable of unsupervised self-driving, and the same was said about HW3 at one point, only for Tesla to admit last quarter that it would, unfortunately, not be possible. Perhaps AI4 vehicles might need this camera washer as a prerequisite, just as HW3 cars will need that camera and computer upgrade.
This could be the first hint of that’s where we are headed.
Tesla has started rolling out a broader change to the ride experience for its Robotaxi fleet by silencing turn signals, but the change is certainly polarizing.
Tesla has generally made it clear that its purpose-built ride-hailing platform, Robotaxi, will cater to the rider in nearly every way possible. This includes having climate preferences, music, and other personal settings loaded up in the car as the rider enters.
But Tesla is taking it a step further by muting turn signal chimes altogether, a change that appears to be a way to make the ride more peaceful:
Tesla has finally turned off the blinker/turn signal noises in their Model Y Robotaxis.
This is a small update, but will definitely be noticeable for riders. It didn’t really make much sense to leave the turn signal sound on when it’s Unsupervised. pic.twitter.com/ITwx60PAMO

However, there are a handful of people who are not thrilled about this change. Turn signals are a conditioned part of the human mind for those who ride in a car regularly.
-
Taking a turn without one feels strange and odd, and not hearing it click while activated could set off some alarms for riders, who might use the noise as confirmation that other drivers know of their intention to turn.
I kind of like it being on, threw me off when riding with Zoox who has had it disabled
— Dan Burkland (@DBurkland) July 27, 2026
Turn signal noises are still audible in customer cars, so if you use FSD in your personal vehicle, you will still hear the turn signal.
The move is certainly one that is unique, but not one that separates it from other ride-sharing services. In a normal car, the clicking sound confirms to the driver that the blinker is active. In a fully driverless Robotaxi, that feedback serves no purpose for passengers, other than peace of mind.
