SpaceX’s first orbital-class Starship ‘tank farm’ is almost finished

Published

on

Roughly six months after the process began, SpaceX has installed the seventh and final custom-built propellant storage tank at Starbase’s first orbital-class Starship launch site.

Built out of the same factory and parts as the steel tanks that make up most of the two-stage Starship rocket’s structure, SpaceX completed the first two of those ‘ground support equipment (GSE)’ tanks in April and wasted no time installing both at Starbase’s orbital launch site (OLS). However, after a strong start, GSE tank work seemingly halted for several months and it wasn’t until August that SpaceX first enclosed one of the then three installed tanks with a sleeve designed to insulate their cryogenic contents. Since then, progress has picked back up and SpaceX has built and installed another three (for a total of six) storage tanks over the last two months.

That work effectively culminated on September 7th with the transport of the farm’s seventh and final GSE tank from build site to launch pad.

Unintuitively known as GSE-8 after SpaceX chose to scrap one of the original seven planned tanks earlier this year, the company wasted no time installing it shortly after its two-mile trip down the highway. GSE-8 is the second of two liquid methane (LCH4) tanks now installed at the orbital launch site and joins another three liquid oxygen (LOx) and two liquid nitrogen (LN2) tanks for a total of seven.

Combined, the OLS tank farm should be able to store more than 2400 tons of LCH4 and 4000 tons of LOx, as well as 2600+ tons of LN2 to be used for ‘subcooling’ (and thus densifying) that propellant well below its boiling point. Ultimately, that means that despite the massive scale of Starbase’s first orbital-class tank farm, it will still only hold enough propellant for a single orbital Starship launch and have to be almost fully restocked after each flight.

Given the logistical nightmare of arranging something like 100+ tanker trucks for each tank farm ‘refill,’ a process that could easily take a week or more on its own, it should come as no surprise that SpaceX is also building a dedicated liquid oxygen and nitrogen plant adjacent to its Starbase factory. On top of liquid natural gas (LNG) refinery and tenuous plans to potentially tap local natural gas wells, SpaceX is clearly well aware of the logistical challenges of regular Starship launches.

While there are no clear signs of the inevitable permitting and environmental reviews it would require, it’s likely that SpaceX will eventually create a brief above or below-ground cryogenic pipeline connecting its propellant factory to Starbase’s orbital launch site(s). If or when implemented, that would allow SpaceX to resupply its two planned orbital tank farms with minimal effort or human intervention beyond the process of producing the propellant.

For the time being, SpaceX will likely rely on a slow but simple parade of tanker trucks to gradually fill its first orbital tank farm. Before even that process is possible, though, SpaceX will need to finish plumbing GSE-8 and several other tanks, install the last two insulative ‘cryoshells,’ and finally fill the annuli between all seven tanks and their shells with an insulative foam-like material known as perlite. Dozens of bags of perlite and several kilns (used to expand the material into low density insulation) are already distributed around the orbital tank farm.

Meanwhile, SpaceX also continues to slowly fill the first two completed OLS tanks (nominally meant to hold LOx) with liquid nitrogen, serving both to test the tanks and pad plumbing and to clean their interiors for liquid oxygen service. Ultimately, while a good amount of work remains, Starbase’s first orbital-class tank farm could be fully ready to support its first Super Heavy booster proof and static fire test campaign just a few weeks from now.

Tesla Cybertruck fleet takes over at SpaceX’s Starbase

Interestingly, the Cybertruck uses the same exterior, a stainless steel alloy, as SpaceX rockets. This synergy between the two companies and their very different products shows a very unified mentality between Musk companies.

Tesla Cybertrucks have taken over at SpaceX’s Starbase facility in Texas, as hundreds of the all-electric pickup trucks were spotted late last week rounding out a massive fleet of vehicles.

The Cybertruck fleet is geared toward replacing gas vehicles that are used at Starbase for everyday operations. The only surprise about this is that it was not done sooner:

Deliveries have been going on for a few weeks, as Cybertrucks have made their way across the state of Texas from Austin to Starbase so they could be included in SpaceX’s fleet of vehicles at the facility.

Interestingly, the Cybertruck uses the same exterior, a stainless steel alloy, as SpaceX rockets. This synergy between the two companies and their very different products shows a very unified mentality between Musk companies.

However, there are some other perspectives to consider as SpaceX is utilizing such a massive fleet of Cybertrucks. Some media outlets (unsurprisingly) are seeing this as a move of weakness by both Tesla and SpaceX, as the aerospace company is, in a sense, “bailing out” lagging sales for the all-electric pickup.

It’s no secret that Tesla has struggled with the Cybertruck this year, and deliveries have been underwhelming in the sense that the company was anticipating between 1 million and 2 million orders for the vehicle before it was widely produced.

A lot of things changed with the Cybertruck between its 2019 unveiling and 2023 initial deliveries, most notably, price.

The price of the Cybertruck swelled significantly and priced out many of those who had pre-ordered it. Some have weighed the option of whether this purchase was a way to get rid of sitting inventory.

However, it seems more logical to consider the fact that SpaceX was likely always going to transition to Teslas for its fleet, especially at Starship, at some point.

It doesn’t seem out of the question that one Musk company would utilize another Musk company’s products, especially considering the Cybertruck has been teased as the vehicle that would be present on Mars.

Elon Musk subtly confirms one of Tesla AI8’s uses, and it’s literally out of this world

Elon Musk appears to have subtly confirmed that Tesla’s upcoming AI8 chip won’t be limited to vehicles or robots alone.

Elon Musk appears to have subtly confirmed that the uses of Tesla’s upcoming AI8 chip won’t be limited to vehicles or humanoid robots alone.

If Musk’s recent responses on X are any indication, it would appear that Tesla’s AI8 will be used by the CEO’s other companies, and its applications would literally extend out of this world.

Tesla’s AI8 could extend beyond vehicles

Musk’s update came on the heels of his recent comments, where he revealed that Tesla was not just working on its AI5 and AI6 chips. The company is also designing AI7 and AI8. This comment caught a lot of attention, with some wondering why Tesla feels the need to design an AI8 chip when AI4 seems on track to be a good fit for autonomous driving. 

Amidst these speculations, an X user suggested that Elon Musk’s comment about AI8 being out of this world could actually be quite true in the literal sense, as it could be used as the chip for SpaceX’s orbit data centers. Musk subtly confirmed this, as he responded to the X user’s post with a bullseye emoji.

Musk’s subtle confirmation that AI8 will be used by SpaceX’s in-space data centers presents a pretty interesting future for the electric vehicle maker. Synergy among Elon Musk-led companies is nothing new, but having Tesla produce chips for SpaceX is undoubtedly something that’s never really been done before.

SpaceX’s space-based computing with Starlink V3 satellites

Musk previously stated that SpaceX plans to use its Starlink V3 satellites to develop space-based data centers. In response to an Ars Technica report on autonomous space construction, he wrote on X: “Simply scaling up Starlink V3 satellites, which have high-speed laser links, would work. SpaceX will be doing this.”

The concept, while ambitious, could address growing energy and cooling constraints facing Earth-based data centers amid the AI boom. Space-based clusters could also cut down on land and water usage, though critics have questioned their cost and maintainability.

Musk recently called the orbital data center project “a very big deal,” and given SpaceX’s history of turning improbable ideas into operational systems, it may not be too far-fetched at all, especially since SpaceX’s Starlink V3 platform is capable of up to 1 terabit per second (Tbps) throughput.
