SpaceX’s second Super Heavy booster enters production in South Texas
In a rare burst of visible activity, SpaceX’s South Texas Starship factory has begun fabricating a second Super Heavy booster and taken a significant step forward on the first prototype.
Set to be the largest operational rocket stage ever built by more than a factor of two, Super Heavy is the booster tasked with launching a fully fueled and loaded Starship (~1400 mT or 3 million lbs) out of the bulk of Earth’s atmosphere. Powered by up to 28 Raptor engines, Super Heavy and Starship will weigh upwards of 5000 metric tons (~11 million lbs) and produce anywhere from 5600 to 7700 metric tons (12.5-17 million lbf) of thrust at liftoff.
Most importantly, though SpaceX CEO Elon Musk has noted that an optimized Starship might be able to reach orbit on a one-way trip, a giant, reasonably efficient booster like Super Heavy is necessary to send Starship into a healthy orbit with all the extra hardware and mass needed to make the orbital spaceship reusable. More than twice as heavy and two-thirds as tall as SpaceX’s workhorse Falcon 9 rocket, that will be no small feat.

Following the appearance of Super Heavy booster number 1’s (BN1) unique common dome, extra-large ‘transfer tube’ segments, and a donut-like eight-Raptor thrust section last month, visible booster work settled down for the next several weeks. In the interim, Musk revealed that SpaceX aims to hop the first Super Heavy booster (BN1) just “a few months” into 2021, followed by the bombshell that the CEO wants to eventually catch Super Heavy boosters to avoid the need for landing legs entirely.

Two weeks after that latest info from Musk and a month after major booster-related factory activity, the first hardware intended for Super Heavy prototype BN2 was spotted on January 19th. Featuring a never-before-seen structural addition in the form of what looks like a hexagonal or octagonal steel ring, the booster’s unique forward dome represents the first real evidence of the modifications needed to install a variety of hardware specific to Super Heavy.
The limited nature and number of current views make it hard to conclude with certainty that the BN2 forward dome’s add-on is hexagonal or octagonal – either could technically be made to work. Barring a surprise design change, Super Heavy – like Falcon 9 and Heavy boosters – will sport four equally spaced grid fins and use them to ensure aerodynamic stability and control authority from hypersonic to supersonic velocities. Based on official SpaceX graphics, Super Heavy’s grid fins will be built out of welded steel, measure some 7 meters (23 ft) tall, and likely weigh 5+ metric tons apiece, thus requiring extremely powerful actuation systems and strong structural support.

Meanwhile, beyond Super Heavy BN2’s first visible appearance, the process of assembling the first booster prototype also took a significant step forward. Sometime on January 19th, SpaceX ended a long period of inactivity, stacking the first Super Heavy ring sections since November 2020. More specifically, SpaceX teams appear to have installed either one or two four-ring sections on an existing booster segment already inside the high bay.

If at rest on top of the rest of the stack in Mary’s (BocaChicaGal) latest photo, one of two Super Heavy ‘stacks’ inside the high bay is now 12 rings (three sections) tall, representing almost a third of a complete 70-meter (~230 ft) tall booster. As of the most recent look inside the high bay, there were two separate stacks of Super Heavy rings – one with four and the other with eight. Based on the location of the new 12-ring stack, it’s more likely than not that SpaceX has simply combined the 12 rings last seen inside the high bay rather than adding one or two new ring sections to one of the two separate stacks.
Ultimately, the return of Super Heavy stacking activity after a two-month pause is an encouraging sign that SpaceX has settled on a design for the first few prototype boosters and could, in fact, be ready to start testing BN1 “a few months” from now.

SpaceX’s Gwynne Shotwell just made a quiet gesture toward Tesla
SpaceX president Gwynne Shotwell quietly followed Tesla on X, and merger watchers noticed right away.
SpaceX President and COO Gwynne Shotwell has started following Tesla’s official account on X, a small change that landed in the middle of a very loud merger conversation. Whole Mars Catalog joked about it on Sunday.
A follow is not an announcement, and neither company has said anything about a deal. What gives the moment weight is the timing. Barclays analyst Dan Levy has told clients that an agreement could come before Tesla’s annual meeting, which must be held by December 6, with SpaceX as the buyer in an all stock deal, as we reported after the Roadster unveiling. Wedbush’s Dan Ives has stuck with a 2027 timeline.
“Shit, I better start following their X account if i’m gonna be helping run the company”

Shotwell is the executive most worth watching if the two companies do move closer. When Musk was asked at the All In Summit why Tesla and SpaceX remain separate, Shotwell sat next to him and said SpaceX personnel had already moved into xAI to fill leadership and engineering gaps. The businesses were integrating “faster than I thought,” she said, though “not fully integrated yet.” Her responsibilities have also grown since SpaceX absorbed xAI, and she now oversees operations that include Grok and the company’s AI compute buildout.
The financial links are already there. Tesla’s $2 billion xAI investment turned into a stake of less than one percent in SpaceX, the two share the Terafab chip project in Austin, and Musk exercised his 2018 Tesla options a week after SpaceX began trading, a sequence analysts flagged as giving SpaceX public shares to use in a deal. Musk holds about 20 percent of Tesla and controls 85.1 percent of SpaceX’s voting power, according to our earlier breakdown.
The next test is close at hand. SpaceX reports its second earnings as a public company on Tuesday after the close, and Tesla follows on Wednesday. Musk told analysts in July that “we can’t talk about combining companies and that kind of thing on an earnings call,” so a direct answer is unlikely from either stage. Tesla shareholders can still submit and vote on questions through the Say portal until 4 p.m. EDT on Monday, and the merger is a recurring theme in the queue.

Tesla Roadster owners to get “Flying Stunt Mode” and looping track access
Musk says Roadster owners can command the unveiling stunts autonomously, with a Texas looping track.
Elon Musk says owners of the new Tesla Roadster will be able to ask the car to perform the stunts Tesla showed at its unveiling, with the car doing the driving itself. Musk made the comment Saturday in a reply on X to tech blogger Robert Scoble, and he added a promise of a looping track at Tesla’s Texas headquarters.
Scoble had argued that the person in the Roadster is not really driving it. In his description, the driver operates a computer that tells another computer what to do, with steering, braking and acceleration all handled by wire. Musk answered, “True. You will be able to ask the Roadster to perform any of the tricks shown autonomously, as it will be sentient. Also, we will have a wild looping track (crazier even than Hot Wheels) at our Texas HQ where you can test out your Roadster.”
@Scobleizer True.

At the October 15 event outside Waco, the car drove up a curved ramp until it was upside down, flew off on cold gas thrusters, flipped and landed. It also hovered over a Cybercab, Cybertruck, Semi, Model Y and Model 3 while moving. As we noted in our breakdown of the three Roadster configurations, Musk said at the event that the car “literally is just going to puff itself up” to perform the maneuvers whenever an owner wants. Saturday’s reply adds that the car would run them on its own.
Tesla has described some of the hardware that would make that possible. The Roadster uses steer by wire with a yoke, and its cold gas thrusters rely on electric actuators for small adjustments in flight. A fan system under the car creates suction, which Tesla says is strong enough to hold it upside down, a setup we covered in our look at the Roadster’s fan system and thrusters.
Musk did not say when an autonomous stunt feature might arrive, how it would work, or what he means by sentient. He also gave no size, location or opening date for the Texas track. Production is planned for Giga Texas in 2027 or 2028, and Tesla says the car is not approved for public road use. The Rocket version, the one built to fly, is invite only.
The comment follows a week of Musk teasing the event, including his claim that the demo would be a banger, which we covered before the stream. Tesla reports third quarter earnings on October 21, and shareholders can submit and vote on questions through the Say portal until 4 p.m. EDT on October 20, according to our earnings Q&A preview. A question about autonomous Roadster stunts and the Texas track would be a quick way to get specifics from management.

How to use Grok Bot to block spam calls and texts
Musk told users to ask Grok Bot to scrub their phone numbers from spam lists.
Elon Musk has a new use case for Grok Bot, and it is the spam call. On Thursday he replied to an X user named Arash with a short instruction: “Ask your @Grok @Bot to remove your phone number from spam call & text lists!” Arash had said he got tired of the calls, had an AI bot find his number on listing sites and file removal requests, and packaged the process as a free skill for others.
The skill is called Spam-Call Scrubber, which is described to find a phone number on people search sites and data brokers, submits the opt outs, completes the confirmation emails those sites send back, and rechecks on a schedule the user picks. Using it requires the Grok Bot app. The pitch is time saved, since most broker opt outs sit behind separate forms on separate sites.
Ask your @Grok @Bot to remove your phone number from spam call & text lists!

Musk said Grok Bot now gives each bot its own email address, and that it can detect scam emails. On Thursday he also said SpaceX would make users whole if the bot botches a purchase or leaks a card, then told users to shop away from Amazon after the retailer blocked the agent, as Teslarati reported. The terms of service we reviewed at the time put responsibility for what an agent does on the user.
For Tesla owners, Grok Bot is not just a phone app. Tesla brought Grok Bot into its vehicles on September 22, and we argued earlier this week that the Cybercab’s real advantage may be the errands it runs during a ride. Every Cybercab and the rest of the Model Y Robotaxi fleet has it enabled. The more routine tasks like this one become, the more a rider has reason to hand over something personal in the back seat.
The new Spam-Call Scrubber skill can be downloaded for free and works on sites that honor removal requests, while noting that listings can reappear, and illegal robocallers do not check any registry. Whether Spam-Call Scrubber cuts anyone’s call volume is something the first wave of users will find out, and Musk’s endorsement guarantees that wave is coming.
