SpaceX is halfway done building the world’s largest rocket booster
New photos of the SpaceX Starship program’s first Super Heavy confirm that the booster prototype – known as Booster Number 1 (BN1) and set to become the largest rocket booster ever built – is already halfway complete.
Set to be the world’s tallest, heaviest, and most powerful liquid rocket booster ever built, Super Heavy is expected to measure some 70 meters (~230 ft) tip to tail, weigh ~3700 metric tons fully fueled, and produce around 7500 metric tons (16.5 million lbf) of thrust at liftoff. Starship, the reusable upper stage and spacecraft SpaceX is busy prototyping and testing, is 40% shorter than Super Heavy and features less than a quarter as many Raptor engines, producing thrust roughly equivalent to Falcon 9’s first stage.

Super Heavy will be equivalent to almost ten Falcon 9s at full thrust and outclass every rocket ever built. However, the basic design of the booster is effectively the same as any other liquid-fueled rocket, opting for a tall and thin Falcon-style cylinder with a high aspect ratio and no exterior coating – just bare metal.
Super Heavy’s airframe is made up of two main propellant tanks joined by a “common dome” and capped at both ends with an interstage (the structure that mates the booster to Starship) and engine/skirt section (encloses the thrust dome, supports landing legs, and houses umbilical ports).


While Super Heavy is dramatically different from Starship by almost any measure, SpaceX has ensured that hardware commonality is as extensive as possible. Ultimately, with minor tweaks, that means that SpaceX can (in theory) build Super Heavy with the exact same tools and techniques it’s used to churn out Starship prototypes.
As of the end of this month, a flurry of public photos from local (and visiting) photographers have confirmed that Super Heavy booster BN1 is effectively halfway to completion and currently stands 18 steel rings tall. Aside from booster-specific layout changes, that 33-meter-tall (~105 ft) barrel section is virtually identical to a Starship’s 20-ring barrel section, lacking only conical nose section that caps them off.

The 18-ring stack also guarantees that the current assembly is Super Heavy BN1’s liquid oxygen (LOx) tank and confirms that like ITS, BFR, Falcon 9, and other SpaceX rockets, Super Heavy’s LOx tank will sit above its fuel (methane) tank. Likely either 38 or 39 rings tall overall, it also indicates that BN1 is a ring away from half of its full height, leaving the integration of its strengthened methane tank, custom engine section, and skirt as the last major tasks standing between SpaceX and its first Super Heavy prototype.


According to Elon Musk, SpaceX will likely hop BN1 if or when it passes initial cryogenic proof and static fire testing. If that goes according to plan, it’s unclear if BN1 can be converted for two-stage Starship launch attempts or if SpaceX will simply move on to BN2 (already under construction).

Tesla is releasing a modified version of FSD v14 for Hardware 3 owners: here’s when
Tesla is releasing a modified version of the Full Self-Driving (Supervised) version 14 suite for Hardware 3 owners, the company announced during the Q3 Earnings Call earlier this week.
Perhaps one of the most pertinent issues for Tesla owners right now is that those owners who have purchased vehicles before 2024 have been stuck with an older version of the company’s self-driving chip, known as Hardware 3 or AI3.
Owners with Hardware 3 vehicles have been stuck in a strange limbo for some time, wondering whether they should wait for the company’s official plans to upgrade them to the newer AI4 or even the to-be-released AI5 chip, or if they should purchase a new vehicle altogether. The upgrade would give them access to the latest Full Self-Driving suite releases, but it would likely cost a good bit of money.
For a while, these owners have been waiting for Tesla to give some sort of update on its plans, as the company has, in a way, danced around the issue by stating it would “take care” of those owners. The problem is, the definition of “take care” is subjective, and nobody knows if that means an upgrade or a free Tesla t-shirt.
Nevertheless, many owners finally got a tad bit more color earlier this week during the Earnings Call, when company executives finally outlined the beginning of a concrete plan to “take care” of HW3 vehicles.
Chief Financial Officer Vaibhav Taneja gave the first bit of the answer, as it is a personal issue to him. He also said that the vehicle he drives is a HW3 car, so it is impacted by the lack of upgrades.
He said:
“We have not completely given up on HW3. These customers are very important. They are early adopters. We will definitely take care of you guys.”
However, Tesla’s Head of AI, Ashok Elluswamy, gave some additional color, revealing that Tesla plans to launch v14 Lite for HW3 cars, and it will be released in Q2 of next year, tentatively:
“Once the v14 release series is fully done, we are planning on working on a v14 Lite version for hardware three. Probably expected in Q2 next year.”
This is somewhat of an answer, but some owners have already voiced discontent with this solution because HW3 will more than likely not be capable of what will be the “feature complete” version of FSD.

Jim Cramer chimes in on Tesla CEO Elon Musk’s pay package
“Don’t be small-minded: Tesla is about robots, Full Self-Driving, the future. Give him his package.”
Investor and host of Mad Money on MSNBC , Jim Cramer, has chimed in on Tesla CEO Elon Musk’s pay package and whether it should be rewarded to the frontman or not.
Cramer has drawn a lot of attention regarding his sentiments on Tesla, as investors have routinely given him a pretty hard time over what he’s said about the company.
For the past few years, we have covered his comments on Tesla when he has something to say, mostly because his opinion on the stock seems to change pretty frequently; at a minimum, he has something different to say about it every few months.
However, Cramer knows Musk’s value to Tesla, and said on Thursday that he believes the CEO deserves his pay package:
“Don’t be small-minded: Tesla is about robots, Full Self-Driving, the future. Give him his package.”

Cramer’s comments come just one day after Tesla’s Q3 2025 Earnings Call, where Musk took several opportunities to call out the importance of the pay package and how it could impact the company’s future — with or without him.
Musk said at one point that he would not feel comfortable continuing to develop the company’s massive fleet of Optimus bots without having appropriate control of the company from a voting perspective.
He said he does not want so much power that if he “were to lose his mind,” he could not be removed. However, he does feel he needs to be protected from “activist shareholders,” or “corporate terrorists” like proxy groups Institutional Shareholder Services (ISS) and Glass Lewis:
“My fundamental concern with regard to how much voting control I have at Tesla is if I go ahead and build this enormous robot army, can I just be ousted at some point in the future? …It’s just, if we build this robot army, do I have at least a strong influence over that robot army, not current control, but a strong influence? That’s what it comes down to in a nutshell. I don’t feel comfortable wielding that robot army if I don’t have at least a strong influence.”
At the end of the call, Musk said:
“Like I said, I just don’t feel comfortable building a robot army here and then being ousted because of some asinine recommendations from ISS and Glass Lewis, who have no freaking clue. I mean, those guys are corporate terrorists.”
Cramer is one of many who realize Musk’s importance to Tesla, and how the company would likely lack the guidance and prowess it does without his planning and drive. However, Tesla shareholders will have the ultimate say on November 6 when they vote on Musk’s compensation plan.

Tesla is stumped on how to engineer this Optimus part, but they’re close
Tesla has been stumped on how to engineer one crucial part of the Optimus bot, but CEO Elon Musk says the company is “on the cusp” of achieving something great with the project.
During the Q3 2025 Earnings Call, Tesla CEO Elon Musk revealed the company is moving closer to a major breakthrough with the Optimus project, and said they are “on the cusp of something really tremendous.”
However, it seems there is one specific portion of the robot that has truly stumped engineers at the company: the hand, fingers, and forearm.
Musk went into great detail about how incredibly complex and amazing the human hand is, highlighting its dexterity and capability, as its ability to perform a wide variety of tasks is especially impressive:
“I don’t want to downplay the difficulty, but it’s an incredibly difficult thing, especially to create a hand that is as dexterous and capable as the human hand, which is incredible. The human hand is an incredible thing. The more you study the human hand, the more incredible you realize it is, and why you need four fingers and a thumb, why the fingers have certain degrees of freedom, why the various muscles are of different strengths, and fingers are of different lengths. It turns out that those are all there for a reason.”
It’s been pretty apparent that Tesla has made massive strides in the Optimus project, especially considering it has been able to walk down hills, learn things like Kung Fu, and even perform service tasks like serving food and drinks.
However, a recent look at a Gen 2.5 version of Optimus posted by Marc Benioff, the CEO of Salesforce, showed that Tesla was likely using mannequin hands until it developed something that was both useful and aesthetically pleasing:
Very likely that these are non-functional to not give away any major details about next-gen Optimus

Musk continued on the call last night that the Tesla team was confronted with an “incredibly difficult” challenge from an engineering perspective, and the hands and actuators for that specific part were tough to figure out:
“Making the hand and forearm, because most of the actuators, just like the human hand, the muscles that control your hand are actually primarily in your forearm. The Optimus hand and forearm is an incredibly difficult engineering challenge. I’d say it’s more difficult than the rest of the robot from an electromechanical standpoint. The forearm and hand are more difficult than the entire rest of the robot. But really, in order to have a useful generalized robot, you do need an incredible hand.”
The CEO continued that developing a useful and effective robot was “crucial to the future of the company,” and that he works with Optimus’s design team each Friday night.
