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 Robotaxi app update now tells riders if Cybercab is the better choice

Tesla’s Robotaxi app now shows ETAs, wait times and availability for Cybercab and Model Y.

Tesla has rolled out a new vehicle selection screen in its Robotaxi app, and it puts the numbers riders care about most in front of them before they book.

Version 26.11.0 of the app shows the estimated arrival time, the expected wait and current availability for each vehicle option on a single screen, according to a video shared by @gheeunit  on X on November 7. Riders deciding between a Cybercab and a Model Y Robotaxi can now compare those figures side by side instead of picking a car first and learning how long it will take afterward.

Tesla first gave riders that choice on September 3, the day paid Cybercab rides began in Austin. The original version of the screen listed the Cybercab, which seats two, next to the Model Y, which seats four. A later build, 26.8.2, added a seating capacity indicator so groups knew which car would fit them. What it did not show was whether choosing the Cybercab meant standing on the curb a few extra minutes.

That question matters more now than it did two months ago. Tesla had 45 Cybercabs on the Texas DMV roster when rides started. By late October the state listed 573, alongside 631 Model Ys, and community trackers logged a record 1,576 Cybercab sightings across Austin on Halloween alone. With two large fleets sharing one service area, the closest car and the quickest pickup are not always the same vehicle.

Inline availability also changes what happens when demand spikes. If no Cybercab is free nearby, the rider sees that on the selection screen rather than after trying to book one.

For now the comparison is mostly an Austin feature. Riders in Dallas, Houston, Fort Worth and the Florida markets are still matched with Model Y vehicles, though Tesla said on its third quarter earnings call that Cybercab rides would launch in Dallas this month.

The update follows a steady run of smaller changes to the rider experience. Late last month Tesla brought a quiet mode that blacks out the cabin screen to Model Y Robotaxis after first testing it in the Cybercab, and it has stretched Austin service to run from 6 a.m. to 2 a.m.

The Cybercab side of that selection screen is about to get much busier. Elon Musk said this week that Tesla will wind down Cybertruck production at Gigafactory Texas around the middle of 2027 to make room for more Cybercab output, and Tesla has said it is aiming to get Cybercabs to customers by the end of this year.

Tesla has not published official release notes for version 26.11.0.

Tesla is ending Cybertruck production

Tesla is ending Cybertruck production sometime in mid-2027, according to CEO Elon Musk.

Musk made the announcement on X last night, which came as a shock to many. He said that the Cybertruck will end production “to make room for increased Cybercab production” at Gigafactory Texas.

It is a huge blow to the fans of Tesla who have come to love the Cybertruck and identify with it as a symbol of their fandom. It has been the best-selling electric pickup, but it has had an underwhelming sales performance in terms of what was expected. This is mostly due to Tesla not meeting the prices it planned to offer the Cybertruck, as its unveiling and actual release were four years apart.

Overall, the responses were mixed. Some fans understood the move toward Cybercab production, especially as Tesla is truly pushing the autonomous future through its Robotaxi platform. However, others did not understand it.

“Damn, how many Cybercabs do you guys need?” one response read. Another said it was “Sad but understandable.”Even analyst Gary Black had responded to the news, stating he hoped Tesla planned to replace it with a traditional pickup design.

It doesn’t seem like that will be the case.

Tesla is so hell-bent on delivering autonomy and eventually providing a driverless service that owning a car seems like an arbitrary idea, according to their thesis. Instead, Cybercabs will be available to pick you up and drop you off on demand, safely, without any human help.

As a result, Tesla has thinned its lineup considerably, and one can only ask where the vehicle lineup goes from here. Eventually, it seems like Cybercab could be the only vehicle that Tesla will sell.

SpaceX’s next Starship flight set to make history on Friday the 13th

SpaceX is targeting Friday, November 13 for Starship Flight 15 and its first ship catch.

SpaceX is targeting Friday, November 13 for Starship Flight 15, the mission the company plans to use for its first attempt at catching the ship itself with the launch tower.

SpaceX Vice President of Launch Kiko Dontchev shared the date on stage at the UP.Summit on Thursday, according to Ars Technica’s Eric Berger, who was in attendance. It is the first launch target to come directly from a SpaceX executive. Until now, the public schedule had relied on FAA air traffic planning slides, which listed Flight 15 for no earlier than November 8 and later November 12. SpaceX has not posted an official mission page yet, and no launch time has been shared.

The date lands inside the window Elon Musk sketched out last month. Speaking at Giga Texas on October 10, Musk said the flight would “probably launch a little bit before Thanksgiving,” as Teslarati reported. On SpaceX’s third quarter earnings call ten days later, he confirmed that Flight 15 would try to catch both the Super Heavy booster and the ship, and put the odds of a successful ship catch at “more likely than not.” SpaceX also aired an animation of the maneuver during that webcast, showing the ship swinging vertical over Starbase before dropping into the tower’s chopsticks.

The hardware is ready. Booster 22 fired all 33 of its Raptor engines for a full duration static fire at Pad 2 on October 25. Ship 42 followed with a single engine burn simulating a deorbit maneuver on October 26 and a 60 second firing of all six engines the next day, according to NASASpaceflight. Ship 42 had already rehearsed the catch in September, when the Pad 2 arms lifted it into position and crews connected the quick disconnect arm while the vehicle hung from the tower.

The remaining hurdle is regulatory. The FAA’s Starship page does not yet list a Flight 15 license. SpaceX President Gwynne Shotwell said in October that, after “significant constructive engagement with the FAA,” she expects the license to cover a return to the launch site and a tower catch for both stages. Bringing the ship home means a reentry path that heads toward land, rather than ending over open ocean as every Starship flight so far has.

SpaceX has caught Super Heavy three times, on Flights 5, 7 and 8, but the ship comes back from orbital velocity and has never been caught. Flight 14 on September 28 was the first Starship to reach orbit, deploying 26 Starlink V3 satellites before splashing down despite an early engine shutdown that Musk blamed on engine computer software.

Musk has called a successful ship catch “the first time that there’s been full recovery of an orbital class rocket,” and he has already named the step after it: a Flight 16 where both the booster and the ship fly again. NASASpaceflight reports that Ship 43, the next vehicle in line, is set for static fire testing in December.
