SpaceX’s first Starship booster a step closer as custom parts arrive
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.
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 plans for largest Australian Supercharger yet
The company has a 20-stall site in the city of Goulburn in New South Wales, which is an ideal location for trips between Sydney and Canberra, two major cities.
Tesla is planning to build its largest Supercharger in Australia yet, expanding on the infrastructure the company has built for electric vehicles.
The company has a 20-stall site in the city of Goulburn in New South Wales, which is an ideal location for trips between Sydney and Canberra, two major cities.
However, according to The Driven, a new Australian Supercharger is on the way, and it is going to be the biggest in the country, accounting for more than 25 stalls total. They will likely be V4 Superchargers, Tesla’s fastest piles that enable some serious range for cars that will plug in.
@LudicrousFeed Before I forget, one for tonight. Highway service centre near Mackay with 25+ charging stalls!

Tesla is operating 148 active Supercharger sites in Australia, with 80 of those being available to non-Tesla EVs as a part of the company’s initiative to make things accessible for all electric vehicle owners.
The expansion of Tesla Superchargers is welcome for all EV owners, especially as there are so many automakers that have access to the network. It is widely reliable and extremely dependable; it is tough to find a Supercharger location that is completely out of service.
The opening of the stalls will be welcome for the Tesla owners of Australia, especially as the Model Y continues to be a major contributor to the company’s prowess in the market.
Tesla’s sales performance in Australia showed a mixed but challenging picture in 2025, with the company delivering 28,856 new vehicles, marking a significant 24.8% decline from 38,347 units in 2024.
This represented the brand’s largest annual drop on record and the second consecutive year of decline, amid intensifying competition from Chinese EV makers like BYD and shifting buyer preferences toward SUVs. The Tesla Model Y remained a standout performer and Australia’s best-selling electric vehicle, with 22,239 deliveries, up 4.6percent year-over-year, accounting for about 77 percent of Tesla’s total sales.
The mid-year launch of the updated “Juniper” Model Y helped sustain momentum in the popular mid-size SUV segment.
In contrast, the Model 3 sedan struggled sharply, plummeting 61.3 percent to just 6,617 units, as consumers favored SUVs and faced growing options in the sedan category.
Despite the overall dip, Tesla held onto leadership in the EV segment, capturing roughly 28 percent of the BEV market. Australia’s EV market grew robustly, surpassing 156,000 sales and reaching 13 percent market share, up 38.7 percent from 2024, highlighting strong broader adoption even as Tesla faced headwinds.
Early 2026 data suggests a rebound, with EV sales nearly doubling year-over-year in February and the Model Y showing strong gains, positioning Tesla for potential recovery amid ongoing competition.

Tesla Model Y L gets new entertainment feature
Beyond audio quality, Immersive Sound X aligns with Tesla’s ecosystem of over-the-air updates, potentially allowing future refinements.
Tesla is including a new entertainment feature in the Model Y L, improving the vehicle even further and making it what appears to be the best configuration of the all-electric crossover globally.
Unfortunately, we in the U.S. do not yet have access to the vehicle, and the plans for it to enter the market remain up in the air, as CEO Elon Musk has said it could appear late this year. However, there is nothing concrete at this time.
Tesla’s latest enhancement to the Model Y L is a new Immersive Sound X feature, exclusive to the Model Y L.

It aims to transform the in-car listening experience into something truly cinematic. First introduced by Tesla China in October 2025, this advanced audio mode is now rolling out to deliveries in Australia and New Zealand, highlighting Tesla’s approach to region-specific premium upgrades.
At its core, Immersive Sound X leverages real-time sound extraction technology to create a customizable 3D soundstage. Using advanced algorithms, it analyzes audio tracks to separate direct sounds, such as vocals or lead instruments, from ambient elements like echoes and reverb.
The system then positions direct sounds front and center while diffusing ambient sounds to the side and rear speakers, simulating an expansive virtual environment. This results in a heightened sense of depth and spatial awareness, making listeners feel as if they’re in a concert hall or studio.
What sets Immersive Sound X apart from the standard Immersive Sound found in other Tesla models is its hardware dependency and enhanced processing. The Model Y L boasts an 18-speaker system with a subwoofer, compared to the 15-speaker setup, plus a subwoofer, in the Model Y Long Range’s previous premium audio configuration.
This upgrade provides more “kick” and precision, enabling finer control over the soundstage. Unlike traditional surround sound, which requires multi-channel mixes like Dolby Atmos, Immersive Sound X works with any stereo source from platforms like Spotify or Apple Music, so every owner will be able to use it.
Tesla Model Y lineup expansion signals an uncomfortable reality for consumers
You can fine-tune the experience via an adjustable immersion slider, scaling the “size” of the virtual space to personal preferences. This caters to a more custom sound.
An Auto mode intelligently adapts based on media type, whether it’s music, podcasts, or videos, ensuring optimal immersion without manual tweaks. This feature is unavailable on standard Model Y variants (with 7 or 15 speakers) or Model 3 trims, underscoring Tesla’s strategy to differentiate higher trims through superior hardware and software integration.
Beyond audio quality, Immersive Sound X aligns with Tesla’s ecosystem of over-the-air updates, potentially allowing future refinements.
For audiophiles and casual listeners alike, it elevates mundane commutes into immersive journeys, proving Tesla’s commitment to blending cutting-edge tech with user-centric design.

Elon Musk teases crazy outlook for xAI against its competitors
Musk’s response was vintage hyperbole, designed to rally supporters and dismiss doubters, something his responses on social media often do.
Elon Musk has never been one to shy away from crazy timelines, massive expectations, and outrageous outlooks. However, his recent plans for xAI and where he believes it will end up compared to its competitors are sure to stimulate conversation.
In a bold and characteristic response on X, Elon Musk fired back at a recent analysis that positioned his AI venture, xAI, as lagging behind industry frontrunners.
The post, from March 14, came as a direct reply to forecaster Peter Wildeford’s assessment, which drew from benchmarks and reporting to rank AI developers.
xAI will catch up this year and then exceed them all by such a long distance in 3 years that you will need the James Webb telescope to see who is in second place
— Elon Musk (@elonmusk) March 14, 2026
Wildeford placed Anthropic, Google, and OpenAI in a virtual tie at the top, with xAI and Meta trailing by about seven months. Chinese players like Moonshot, Deepseek, zAI, and Alibaba were estimated to be nine months behind, while France’s Mistral lagged by about a year and a half.
Musk’s response was vintage hyperbole, designed to rally supporters and dismiss doubters, something his responses on social media often do.
He claimed xAI would “catch up this year,” meaning by the end of 2026, erasing that seven-month deficit against the leaders. But he didn’t stop there.
Musk escalated his vision to 2029, predicting xAI would “exceed them all by such a long distance” that observers would need the James Webb Space Telescope, NASA’s orbiting observatory stationed about 930,000 miles from Earth, to spot whoever lands in second place. This analogy underscores Musk’s confidence in xAI’s trajectory, implying an astronomical lead that could redefine the AI landscape.
Breaking down these claims reveals Musk’s strategic optimism. First, the short-term catch-up: xAI, launched in 2023, has already released models like Grok, but recent benchmarks, including those for Grok 4.2, have shown it falling short in capabilities compared to rivals.
Anthropic’s Claude series, Google’s Gemini, and OpenAI’s GPT models dominate in areas like reasoning, coding, and multimodal tasks. Musk’s assertion suggests aggressive scaling in compute, talent, or architecture, perhaps leveraging xAI’s ties to Tesla’s Dojo supercomputers or Musk’s vast resources, to close the gap swiftly.
The longer-term dominance by 2029 paints an even more audacious picture. Musk envisions xAI not just parity but supremacy, outpacing competitors in innovation speed and model sophistication.
This could involve breakthroughs in energy-efficient training, real-world integration, like Tesla’s robotics, or ethical AI alignment, aligning with Musk’s stated goal of “understanding the universe.”
Critics, however, point to parallels with Tesla’s Full Self-Driving delays; one reply highlighted Musk’s 2023 promise of FSD readiness. Musk has made this promise for many years, and although the system has been strong and improving, it is still a ways off from the completely autonomous operation that was expected by now.
Tesla Full Self-Driving v14.2.2.5 might be the most confusing release ever
Musk’s comment highlights the intensifying U.S.-centric AI race, with xAI challenging the “three-way” dominance noted by Wharton professor Ethan Mollick, whom Wildeford quoted. As geopolitical tensions rise—evident in the Chinese firms’ lag—Musk’s tease could spur investment and talent wars.
Yet, it also invites scrutiny: Will xAI deliver, or is this another telescope-needed mirage? In an industry where timelines slip but stakes soar, Musk’s words keep the spotlight on xAI’s ambitious path forward.
