SpaceX’s orbital Starship launch pad tank farm comes to life for the first time

Update: Two days after a bevy of tanker trucks began to arrive at SpaceX’s orbital Starship launch site with load upon load of cryogenic liquid nitrogen, the company’s custom-built tank farm appears to have taken its very first ‘breaths.’

In other words, at least one of seven massive propellant storage tanks – two of which appear to have been fully completed and insulated – began venting. For a tank like SpaceX’s ground support equipment (GSE) tanks, the level of venting observed can only mean one thing: pressure maintenance during operations with cryogenic fluids. As cryofluids are loaded into empty tanks, they inevitably come into contact with warm pipes and tank walls, rapidly warming a portion of the liquid that then boils into gas. Tanks then need to vent that excess gas to avoid bursting.

In the case of SpaceX’s two completed liquid oxygen GSE tanks and a spate of liquid nitrogen (LN2) deliveries this week, it’s clear that the company has begun the process of testing and activating part of its brand new orbital-class Starship tank farm – beginning with much less risky LN2 proof testing. Filling the two finished LOx tanks with LN2 should also serve the dual purpose of flushing and cleaning them of any debris or contaminants, ensuring that it’s safe to fill them with LOx when the time comes.

For the first time, SpaceX appears to have begun delivering large quantities of cryogenic fluids to Starship’s orbital launch pad – still under construction but fast approaching some level of initial operational capability.

Sometime in the morning on September 19th, a semi-truck carrying a cryogenic liquid nitrogen (LN2) transport trailer arrived at SpaceX’s Starbase launch facilities. Normally, that would be a completely mundane, uninteresting event: SpaceX has used and will continue to use liquid nitrogen to safely proof test Starship prototypes and supercool their liquid methane (LCH4) and oxygen (LOx) propellant for the indefinite future. However, up to now, 100% of all Starbase cryogen deliveries have gone to the suborbital launch site, where two “mounts” and a few concrete aprons have supported all Starship and Super Heavy tests and launches to date.

Instead, this particular LN2 tanker headed for Starbase’s first orbital tank farm and began to offload its cryogenic liquid cargo at a number of brand new fill stations specifically designed for the task.

Still well under construction and at least a few weeks or months from total complete, Starship’s orbital launch site tank farm will ultimately be a group of eight massive storage tanks surrounded by thousands of feet of insulated plumbing, industrial pumps, a small army of “cryocoolers,” a blockhouse filled with human-sized valves, and much more. Said tank farm has been under construction for the better part of 2021, beginning with work on its concrete foundation this January.

Nine months later, the orbital tank farm is nearly complete. A power distribution and communications blockhouse has been complete for weeks with virtually all the wiring and cabling needed for the orbital launch mount and tower already in place. Several hundred feet of concrete cable and plumbing conduit have been filled with thousands of feet of wires, cables, and pipes and been sealed and buried. The tank farm blockhouse – where a dozen or so massive valves control the flow of propellant to and from the orbital launch mount and tower – is complete save for some final plumbing.

Finally, seven of eight GSE (ground support equipment) tanks have been installed and partially plumbed. Built in the same factory, six are virtually identical to Starship and Super Heavy tanks and will store LOx (3x), LN2 (2x), LCH4 (2x), and around a million gallons of water. Save for one LCH4 tank, all have been installed at the farm and that last tank (known as GSE8) is nearly complete back at the build site. Additionally, to insulate those seven thin, steel storage tanks, SpaceX has contracted with a water/storage tank company to build seven “cryoshells” and said million-gallon water tank.

The water tank was installed months ago and all seven shells are completed and ready to go as of last month. Only two of those seven cryoshells have been installed – and, rather asymmetrically, both on LOx tanks. SpaceX recently rolled the first LN2 tank cryoshell to the farm and could install it soon but as of now, it will likely be weeks before the orbital tank farm will have sleeved, insulated LOx, LN2, and LCH4 tanks ready for testing.

At the moment, that’s one of the biggest points of uncertainty standing between SpaceX and the ability to test Super Heavy or Starship at the orbital launch site. It’s entirely unclear if uninsulated GSE tanks can support any kind of substantial testing – like, say, the first full Super Heavy static fire test campaign – before their contents effectively boil off. As such, it’s a bit of mystery why SpaceX then had at least three tanker loads of liquid nitrogen – likely more than 70 tons (~150,000 lb) total – delivered to the orbital tank farm on September 19th.

By all appearances the first time that the farm’s actual main tanks have been filled with anything, that liquid nitrogen seems to have been loaded into one or both of the two insulated LOx tanks. There are two or three main explanations. First, SpaceX could simply be testing those more or less completed tanks with their first cryogenic fluids. Those partial ‘cryo proof’ tests would also help clean and flush out the interior of the LOx tanks, removing mundane debris or contamination that could become a major hazard when submerged in a high-density oxidizer. Given that both tanks can easily hold ~1300 tons (~2.9M lb) of liquid nitrogen, 70 tons is more of a tickle than a test, though, so a magnitude more would need to be delivered to perform even a half-decent bare-minimum cryoproof.

The other distinct possibility is that SpaceX plans to temporarily use one or both of the only two finished orbital pad tanks to store liquid nitrogen for Super Heavy Booster 4’s first cryogenic proof test. Either way, SpaceX has test windows scheduled every day this week, beginning with a six-hour window that opens at 5pm CDT today (Sept 20). Stay tuned to find out what exactly SpaceX plans to test and if the orbital tank farm and its first taste of liquid nitrogen are involved!

Tesla’s Elon Musk posts updated Robotaxi fleet ramp for Austin, TX

Musk posted his update on social media platform X.

Elon Musk says Tesla will “roughly double” its supervised Robotaxi fleet in Austin next month as riders report long wait times and limited availability across the pilot program in the Texas city. Musk posted his update on social media platform X.

The move comes as Waymo accelerates its U.S. expansion with its fully driverless freeway service, intensifying competition in autonomous mobility.

Tesla to increase Austin Robotaxi fleet size

Tesla’s Robotaxi service in Austin continues to operate under supervised conditions, requiring a safety monitor in the front seat even as the company seeks regulatory approval to begin testing without human oversight. The current fleet is estimated at about 30 vehicles, StockTwists noted, and Musk’s commitment to doubling that figure follows widespread rider complaints about limited access and “High Service Demand” notifications.

Influencers and early users of the Robotaxi service have observed repeated failures to secure a ride during peak times, highlighting a supply bottleneck in one of Tesla’s most visible autonomy pilots. The expansion aims to provide more consistent availability as the company scales and gathers more real-world driving data, an advantage analysts often cite as a differentiator versus rivals. 

Broader rollout plans

Tesla’s Robotaxi service has so far only been rolled out to Austin and the Bay Area, though reports have indicated that the electric vehicle maker is putting in a lot of effort to expand the service to other cities across the United States. Waymo, the Robotaxi service’s biggest competitor, has ramped its service to areas like the San Francisco Bay Area, Los Angeles, and Phoenix.

Analysts continue to highlight Tesla’s long-term autonomy potential due to its global fleet size, vertically integrated design, and immense real-world data. ARK Invest has maintained that Tesla Robotaxis could represent up to 90% of the company’s enterprise value by 2029. BTIG analysts, on the other hand, added that upcoming Full Self-Driving upgrades will enhance reasoning, particularly parking decisions, while Tesla pushes toward expansions in Austin, the Bay Area, and potentially 8 to 10 metro regions by the end of 2025.

Tesla finishes its biggest Supercharger ever with 168 stalls

Tesla has finished construction at its biggest Supercharger ever in Lost Hills, California, and all 168 stalls are officially open as of today.

After several years of development, the company has officially announced that the Lost Hills Supercharger, known as Project Oasis, is officially open with 168 stalls active and available to drivers.

Tesla announced the completion of the Lost Hills Supercharger on Tuesday, showing off the site, which is powered by 10 Megapack batteries for storage and is completely independent of the grid, as it has 11 MW of solar panels bringing energy to the massive Battery Energy Storage System (BESS).

This is the largest Supercharger in the world and opens just in time for the Thanksgiving holiday, which is the most-traveled weekend of the year in the United States.

Spanning across 30 acres, it was partially opened back in July 2025 as Tesla opened just 84 of the 168 stalls at the site. However, Tesla finished certifying the site recently, which enabled the Supercharger to open up completely.

The site generates roughly 20 GWh of energy annually, which is enough to power roughly 1,700 homes. The launch of this site specifically is massive for the company as it plans to launch more Superchargers in more rural areas, making charging more available for cross-country rides that require stops in more remote regions of the United States.

This is perhaps the only weak point of Tesla’s massive charging infrastructure.

It has some features that are also extremely welcome for some owners, including things like pull-through stalls for those who tow, an idea that was extremely popular following the launch of the Cybertruck.

Tesla has over 70,000 active Superchargers across the world. The company has also made efforts to create unique experiences at some of the stops, most notably with its Tesla Diner, located on Santa Monica Boulevard in Los Angeles.

That Supercharger has two massive drive-in movie theaters and will soon transition to a full-service restaurant following the departure of its executive chef, Eric Greenspan.

Elon Musk has proposed a high-profile gaming challenge for xAI’s upcoming Grok 5. As per Musk, it would be interesting to see if the large language model could beat the world’ best human League of Legends team with specific constraints.

Musk’s proposal has received positive reception from professional players and Riot Games alike, suggesting that the exciting exhibition match might indeed happen. 

Musk outlines restrictions for Grok

In his post on X, Musk detailed constraints to keep the match competitive, including limiting Grok to human-level reaction times, human-speed clicking, and viewing the game only through a camera feed with standard 20/20 vision. The idea quickly circulated across the esports community, drawing commentary from former pros and AI researchers, as noted in a Dexerto report.

Former League pro Eugene “Pobelter” Park expressed enthusiasm, offering to help Musk’s team and noting the unique comparison to past AI-versus-human breakthroughs, such as OpenAI’s Dota 2 bots. AI researcher Oriol Vinyals, who previously reached Grandmaster rank in StarCraft, suggested testing Grok in RTS gameplay as well. 

Musk welcomed the idea, even responding positively to Vinyals’ comment that it would be nice to see Optimus operate the mouse and keyboard.

Pros debate Grok’s chances, T1 and Riot show interest

Reactions weren’t universally optimistic. Former professional mid-laner Joedat “Voyboy” Esfahani argued that even with Grok’s rapid learning capabilities, League of Legends requires deep synergy, game-state interpretation, and team coordination that may be difficult for AI to master at top competitive levels. Yiliang “Doublelift” Peng was similarly skeptical, publicly stating he doubted Grok could beat T1, or even himself, and jokingly promised to shave his head if Grok managed to win.

T1, however, embraced the proposal, responding with a GIF of Faker and the message “We are ready,” signaling their willingness to participate. Riot Games itself also reacted, with co-founder Marc Merrill replying to Musk with “let’s discuss.” Needless to say, it appears that Riot Games in onboard with the idea.

Though no match has been confirmed, interest from players, teams, and Riot suggests the concept could materialize into a landmark AI-versus-human matchup, potentially becoming one of the most viewed League of Legends events in history. The fact that Grok 5 will be constrained to human limits would definitely add an interesting dimension to the matchup, as it could truly demonstrate how human-like the large language model could be like in real-time scenarios.

Tesla has passed a key milestone, and it was one that CEO Elon Musk initially mentioned more than nine years ago when he published Master Plan, Part Deux. 

As per Tesla China in a post on its official Weibo account, the company’s Autopilot system has accumulated over 10 billion kilometers of real-world driving experience.

Tesla China’s subtle, but huge announcement

In its Weibo post, Tesla China announced that the company’s Autopilot system has accumulated 10 billion kilometers of driving experience. “In this respect, Tesla vehicles equipped with Autopilot technology can be considered to have the world’s most experienced and seasoned driver.”

Tesla AI’s handle on Weibo also highlighted a key advantage of the company’s self-driving system. “It will never drive under the influence of alcohol, be distracted, or be fatigued,” the team wrote. “We believe that advancements in Autopilot technology will save more lives.”

Tesla China did not clarify exactly what it meant by “Autopilot” in its Weibo post, though the company’s intense focus on FSD over the past years suggests that the term includes miles that were driven by FSD (Beta) and Full Self-Driving (Supervised). Either way, 10 billion cumulative miles of real-world data is something that few, if any, competitors could compete with.

Elon Musk’s 10-billion-km estimate, way back in 2016

When Elon Musk published Master Plan Part Deux, he outlined his vision for the company’s autonomous driving system. At the time, Autopilot was still very new, though Musk was already envisioning how the system could get regulatory approval worldwide. He estimated that worldwide regulatory approval will probably require around 10 billion miles of real-world driving data, which was an impossible-sounding amount at the time. 

“Even once the software is highly refined and far better than the average human driver, there will still be a significant time gap, varying widely by jurisdiction, before true self-driving is approved by regulators. We expect that worldwide regulatory approval will require something on the order of 6 billion miles (10 billion km). Current fleet learning is happening at just over 3 million miles (5 million km) per day,” Musk wrote.

It’s quite interesting but Tesla is indeed getting regulatory approval for FSD (Supervised) at a steady pace today, at a time when 10 billion miles of data has been achieved. The system has been active in the United States and has since been rolled out to other countries such as Australia, New Zealand, China, and, more recently, South Korea. Expectations are high that Tesla could secure FSD approval in Europe sometime next year as well.
