SpaceX installs full set of car-sized grid fins on second Super Heavy booster
SpaceX appears to have installed a full set of car-sized grid fins on Starship’s second flightworthy Super Heavy booster, leaving the massive rocket just a few steps away from completion.
Measuring ~69m (~225 ft) tall and 9m (~30 ft) wide, Super Heavy Booster 5 (B5) – like B4 before it – will be one of two of the largest rocket boosters ever built once completed. In broad strokes, Super Heavy B4 and B5 are the same. Aside from near-identical dimensions, both have been built to hold up to 29 Raptor engines while Starbase has already begun receiving parts of the first 33-engine Super Heavy. That means that Booster 4 and 5 – while both potentially capable of flight – are also pathfinders for an upgraded version of Super Heavy with similar dimensions but the potential to produce more than 40% more thrust once Raptor 2 production takes over.
While more similar than not, there are significant differences between SpaceX’s first and second flightworthy Super Heavy boosters.
The biggest visible differences are tweaks SpaceX has made to the Super Heavy assembly process. Booster 4 was assembled out of mostly naked steel rings and only had thousands of feet of external plumbing, wiring, raceways, and hardware installed after it was stacked to its full height. That may partially be because CEO Elon Musk had ordered SpaceX to complete the first full-height Starship stack by early August, requiring the build team to prioritize speed above all else.
Regardless, SpaceX appears to be outfitting Super Heavy Booster 5’s exterior before and during the process of stacking the booster to its final height. Most sections of 3-4 steel rings have had partial plumbing and raceways preinstalled, meaning that Booster 5 will be far closer to test readiness than Booster 4 once stacking is complete. Booster 4, on the other hand, required at least several more weeks of outfitting after SpaceX briefly rolled the rocket to the orbital launch pad for a full-stack photo-op and fit check.
On October 12th, after rapidly stacking Super Heavy B5’s upper methane tank to completion, SpaceX began installing the booster’s four car-sized grid fins. Fixed in place and assembled out of welded steel unlike the Falcon family’s deployable, cast titanium fins, Super Heavy grid fins are several times larger and heavier but still serve the same purpose of stabilizing boosters during atmospheric reentry, descent, and landing. Like Booster 4, SpaceX has also installed all four Booster 5 grid fins before stacking the Super Heavy to its full 69-meter height.
Based on B4, that final stack could happen just a few days from now, though there are signs that it might take B5 a fair bit longer. Notably, whereas Booster 4’s aft liquid oxygen (LOx) tank was already fully stacked by the start of grid fin installation, Booster 5’s LOx section is still waiting on its thrust dome. That thrust section was most recently spotted inside a production tent on October 11th – far more thoroughly outfitted than Booster 4’s aft but awaiting installation nonetheless.
That slight difference in timing pales in comparison to a massive tube that may or may not have been installed inside Super Heavy B5 late last month and that definitely wasn’t installed in B4. Without official information, it’s hard to know for sure, but the general community consensus is that this new tube (possibly one of two installed inside Booster 5’s LOx tank) is some kind of header tank or sump meant to collect propellant for Super Heavy’s boostback and/or landing burn.
If SpaceX really is adding header tanks to Super Heavy, it would drastically increase the complexity of booster plumbing, potentially explaining why Super Heavy B5’s thrust section installation is taking longer than B4. Only time (and hopefully a tweet or two from Musk) will tell.
Tesla will increase its Full Self-Driving subscription price, meaning it will eventually be more than the current $99 per month price tag it has right now.
Already stating that the ability to purchase the suite outright will be removed, Tesla CEO Elon Musk said earlier this week that the Full Self-Driving subscription price would increase when its capabilities improve:
“I should also mention that the $99/month for supervised FSD will rise as FSD’s capabilities improve. The massive value jump is when you can be on your phone or sleeping for the entire ride (unsupervised FSD).”
This was an expected change, especially as Tesla has been hinting for some time that it is approaching a feature-complete version of Full Self-Driving that will no longer require driver supervision. However, with the increase, some are concerned that they may be priced out.
$99 per month is already a tough ask for some. While Full Self-Driving is definitely worth it just due to the capabilities, not every driver is ready to add potentially 50 percent to their car payment each month to have it.
While Tesla has not revealed any target price for FSD, it does seem that it will go up to at least $150.

Additionally, the ability to purchase the suite outright is also being eliminated on February 14, which gives owners another reason to be slightly concerned about whether they will be able to afford to continue paying for Full Self-Driving in any capacity.
Some owners have requested a tiered program, which would allow people to pay for the capabilities they want at a discounted price.
Unsupervised FSD would be the most expensive, and although the company started removing Autopilot from some vehicles, it seems a Supervised FSD suite would still attract people to pay between $49 and $99 per month, as it is very useful.
Tesla will likely release pricing for the Unsupervised suite when it is available, but price increases could still come to the Supervised version as things improve.
This is not the first time Musk has hinted that the price would change with capability improvements, either. He’s been saying it for some time. In 2020, he even said the value of FSD would “probably be somewhere in excess of $100,000.”
The FSD price will continue to rise as the software gets closer to full self-driving capability with regulatory approval. It that point, the value of FSD is probably somewhere in excess of $100,000.

Tesla has chosen to axe the ability to purchase Full Self-Driving outright from a select group of cars just days after CEO Elon Musk announced the company had plans to eliminate that option in February.
The company is making a clear-cut stand that it will fully transition away from the ability to purchase the Full Self-Driving suite outright, a move that has brought differing opinions throughout the Tesla community.
Earlier this week, the company also announced that it will no longer allow buyers to purchase Full Self-Driving outright when ordering a pre-owned vehicle from inventory. Instead, that will be available for $99 per month, the same price that it costs for everyone else.
The ability to buy the suite for $8,000 for a one-time fee at the time of order has been removed:

This is a major move because it is the first time Tesla is eliminating the ability to purchase FSD outright for one flat fee to any of its vehicles, at least at the time of purchase.
It is trying to phase out the outright purchase option as much as it can, preparing people for the subscription-based service it will exclusively offer starting on February 14.
In less than a month, it won’t be available on any vehicle, which has truly driven some serious conversation from Tesla owners throughout the community.
There’s a conflict, because many believe that they will now lose the ability to buy FSD and not pay for it monthly, which is an attractive offer. However, others believe, despite paying $8,000 for FSD, that they will have to pay more money on top of that cost to get the unsupervised suite.
Additionally, CEO Elon Musk said that the FSD suite’s subscription price would increase over time as capabilities increase, which is understandable, but is also quite a conflict for those who spent thousands to have what was once promised to them, and now they may have to pay even more money.

Tesla Robotaxi has a highly-requested hardware feature not available on typical Model Ys
These camera washers are crucial for keeping the operation going, as they are the sole way Teslas operate autonomously. The cameras act as eyes for the car to drive, recognize speed limit and traffic signs, and travel safely.
Tesla Robotaxi has a highly-requested hardware feature that is not available on typical Model Ys that people like you and me bring home after we buy them. The feature is something that many have been wanting for years, especially after the company adopted a vision-only approach to self-driving.
After Tesla launched driverless Robotaxi rides to the public earlier this week in Austin, people have been traveling to the Lone Star State in an effort to hopefully snag a ride from one of the few vehicles in the fleet that are now no longer required to have Safety Monitors present.
BREAKING: Tesla launches public Robotaxi rides in Austin with no Safety Monitor
Although only a few of those completely driverless rides are available, there have been some new things seen on these cars that are additions from regular Model Ys, including the presence of one new feature: camera washers.
With the Model Y, there has been a front camera washer, but the other exterior “eyes” have been void of any solution for this. For now, owners are required to clean them manually.
In Austin, Tesla is doing things differently. It is now utilizing camera washers on the side repeater and rear bumper cameras, which will keep the cameras clean and keep operation as smooth and as uninterrupted as possible:

These camera washers are crucial for keeping the operation going, as they are the sole way Teslas operate autonomously. The cameras act as eyes for the car to drive, recognize speed limit and traffic signs, and travel safely.
This is the first time we are seeing them, so it seems as if Safety Monitors might have been responsible for keeping the lenses clean and unobstructed previously.
However, as Tesla transitions to a fully autonomous self-driving suite and Robotaxi expands to more vehicles in the Robotaxi fleet, it needed to find a way to clean the cameras without any manual intervention, at least for a short period, until they can return for interior and exterior washing.
