SpaceX’s first Starship booster a step closer as custom parts arrive

Published

on

While SpaceX remains focused on Starship flight testing as the dust settles from SN8’s launch debut, the company continues to make slow but steady progress building the first Super Heavy booster prototype.

For the most part, SpaceX has learned from trial and error and developed a decent stainless steel rocket manufacturing process by building a dozen Starship prototypes over the last ~12 months, ranging from a lone nosecone tip to stout test tanks and Starship SN8, which launched to 12.5 km (~7.8 mi) earlier this month. Practically identical below the nose, Super Heavy directly benefits from that maturity and is more or less an extended Starship tank section with more engines and bigger legs.

In many ways, Super Heavy can be much simpler than Starship, as a suborbital booster has no need for header tanks, flaps, or a nosecone, and can be much stronger and heavier in all aspects. However, carrying three or more times as propellant as Starship (and carrying Starship itself), Super Heavy also needs to be stronger. All those changes – requiring new design work and new fabrication – take time. In a great sign that most of that work is complete, some of that custom hardware needed to strengthen and power Super Heavy has begun to arrive over the last several weeks.

SpaceX began stacking the first Super Heavy booster (BN1) on November 8th and appears to have more or less paused integration operations after joining eight rings. Production continued apace, however, and no less than five ring sections destined for Super Heavy appeared over the next several weeks. Why assembly slowed down is unclear but it’s reasonable to assume that SpaceX was trying to keep its focus primarily on Starship SN8’s launch debut and the preparation of several other full-scale ships, where early work on Super Heavy could ultimately be for naught if Starship flight tests uncover major design flaws.

Regardless of the reason, BN1 remains eight rings (14.5m/48ft) tall as of December 14th, representing one-fifth of Super Heavy’s full 70-meter (~230 ft) height.

Assuming they aren’t waiting to be scrapped, at least 20-24 of the 31-32 Super Heavy BN1 rings remaining are ready and waiting for dome integration and stacking. (NASASpaceflight – bocachicagal)

On December 17th, one of the parts unique to Super Heavy unexpectedly appeared in SpaceX’s South Texas shipyard, labeled “B1 FWD PIPE DOME”. The dome was quickly sleeved with a stack of three steel rings with labels confirming that the assembly was Super Heavy BN1’s common tank dome – “common” because it’s shared by both booster propellant tanks. The new dome is unique to all previous Starship domes, featuring a smaller, more reinforced cutout – likely because Super Heavy doesn’t need header tanks.

It also appears to borrow from Starship’s forward dome design, using the same rougher steel normally used to cap off Starship methane tanks.

Unlike Starship common domes, which place a spherical methane header tank at the bottom, Super Heavy’s common dome will have a transfer tube welded directly to its nozzle-like opening. As it turns out, what could be the first Super Heavy methane transfer tube was delivered to Boca Chica late last month.

Unlike Starship transfer tubes, the new plumbing appeared to have a much wider diameter and was delivered in four sections, meshing well with the fact that Super Heavy tanks are roughly twice as tall as Starship’s. Able to support as many as 28 Raptors compared to Starship’s 6, Super Heavy transfer tubes will also need to pump more than five times as much methane per second at full thrust, which could explain the larger diameter.

Finally and perhaps most significantly, aerial photos from RGV Photography appeared to capture the first glimpse of what might be the hardest custom part required by Super Heavy – a thrust structure designed to support up to 28 Raptor engines. On December 10th, casually sitting between Starship Mk1’s remains (on the white concrete mount) and a tent, a flat ring with clear eightfold symmetry and a donut-like cutout large enough to fit a Starship thrust puck with room to spare was easily visible.

The hexagonal symmetry was the main giveaway, matching comments from CEO Elon Musk that Super Heavy’s thrust structure will feature a central ring of eight engines surrounded by an outer ring of up to 20 more Raptors. Assuming the first Super Heavy booster only flies with a few Raptor engines, that sole eight-engine ‘puck’ may be all that SpaceX needs to complete BN1.

Tesla makes big Full Self-Driving change to reflect future plans

Published

on

Tesla made a dramatic change to the Online Design Studio to show its plans for Full Self-Driving, a major part of the company’s plans moving forward, as CEO Elon Musk has been extremely clear on the direction moving forward.

With Tesla taking a stand and removing the ability to purchase Full Self-Driving outright next month, it is already taking steps to initiate that with owners and potential buyers.

On Thursday night, the company updated its Online Design Studio to reflect that in a new move that now lists the three purchase options that are currently available: Monthly Subscription, One-Time Purchase, or Add Later:

This change replaces the former option for purchasing Full Self-Driving at the time of purchase, which was a simple and single box to purchase the suite outright. Subscriptions were activated through the vehicle exclusively.

However, with Musk announcing that Tesla would soon remove the outright purchase option, it is clearer than ever that the Subscription plan is where the company is headed.

The removal of the outright purchase option has been a polarizing topic among the Tesla community, especially considering that there are many people who are concerned about potential price increases or have been saving to purchase it for $8,000.

This would bring an end to the ability to pay for it once and never have to pay for it again. With the Subscription strategy, things are definitely going to change, and if people are paying for their cars monthly, it will essentially add $100 per month to their payment, pricing some people out. The price will increase as well, as Musk said on Thursday, as it improves in functionality.

Those skeptics have grown concerned that this will actually lower the take rate of Full Self-Driving. While it is understandable that FSD would increase in price as the capabilities improve, there are arguments for a tiered system that would allow owners to pay for features that they appreciate and can afford, which would help with data accumulation for the company.

Musk’s new compensation package also would require Tesla to have 10 million active FSD subscriptions, but people are not sure if this will move the needle in the correct direction. If Tesla can potentially offer a cheaper alternative that is not quite unsupervised, things could improve in terms of the number of owners who pay for it.

Tesla Model S completes first ever FSD Cannonball Run with zero interventions

The coast-to-coast drive marked the first time Tesla’s FSD system completed the iconic, 3,000-mile route end to end with no interventions.

Published

A Tesla Model S has completed the first-ever full Cannonball Run using Full Self-Driving (FSD), traveling from Los Angeles to New York with zero interventions. The coast-to-coast drive marked the first time Tesla’s FSD system completed the iconic, 3,000-mile route end to end, fulfilling a long-discussed benchmark for autonomy.

A full FSD Cannonball Run

As per a report from The Drive, a 2024 Tesla Model S with AI4 and FSD v14.2.2.3 completed the 3,081-mile trip from Redondo Beach in Los Angeles to midtown Manhattan in New York City. The drive was completed by Alex Roy, a former automotive journalist and investor, along with a small team of autonomy experts.

Roy said FSD handled all driving tasks for the entirety of the route, including highway cruising, lane changes, navigation, and adverse weather conditions. The trip took a total of 58 hours and 22 minutes at an average speed of 64 mph, and about 10 hours were spent charging the vehicle. In later comments, Roy noted that he and his team cleaned out the Model S’ cameras during their stops to keep FSD’s performance optimal. 

History made

The historic trip was quite impressive, considering that the journey was in the middle of winter. This meant that FSD didn’t just deal with other cars on the road. The vehicle also had to handle extreme cold, snow, ice, slush, and rain. 

As per Roy in a post on X, FSD performed so well during the trip that the journey would have been completed faster if the Model S did not have people onboard. “Elon Musk was right. Once an autonomous vehicle is mature, most human input is error. A comedy of human errors added hours and hundreds of miles, but FSD stunned us with its consistent and comfortable behavior,” Roy wrote in a post on X.

Roy’s comments are quite notable as he has previously attempted Cannonball Runs using FSD on December 2024 and February 2025. Neither were zero intervention drives.

Tesla removes Autopilot as standard, receives criticism online

The move leaves only Traffic Aware Cruise Control as standard equipment on new Tesla orders.

Tesla removed its basic Autopilot package as a standard feature in the United States. The move leaves only Traffic Aware Cruise Control as standard equipment on new Tesla orders, and shifts the company’s strategy towards paid Full Self-Driving subscriptions.

Tesla removes Autopilot

As per observations from the electric vehicle community on social media, Tesla no longer lists Autopilot as standard in its vehicles in the U.S. This suggests that features such as lane-centering and Autosteer have been removed as standard equipment. Previously, most Tesla vehicles came with Autopilot by default, which offers Traffic-Aware Cruise Control and Autosteer.

The change resulted in backlash from some Tesla owners and EV observers, particularly as competing automakers, including mainstream players like Toyota, offer features like lane-centering as standard on many models, including budget vehicles.

That being said, the removal of Autopilot suggests that Tesla is concentrating its autonomy roadmap around FSD subscriptions rather than bundled driver-assistance features. It would be interesting to see how Tesla manages its vehicles’ standard safety features, as it seems out of character for Tesla to make its cars less safe over time. 

Musk announces FSD price increases

Following the Autopilot changes, Elon Musk stated on X that Tesla is planning to raise subscription prices for FSD as its capabilities improve. In a post on X, Musk stated that the current $99-per-month price for supervised FSD would increase over time, especially as the system itself becomes more robust.

“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),” Musk wrote. 

At the time of his recent post, Tesla still offers FSD as a one-time purchase for $8,000, but Elon Musk has confirmed that this option will be discontinued on February 14, leaving subscriptions as the only way to access the system.
