SpaceX begins filling Starship’s orbital launch site with rocket propellant
Less than a year after tank farm assembly began in South Texas, SpaceX has begun the painstaking process of filling Starship’s first orbital launch site with thousands of tons of rocket propellant.
Comprised of seven giant custom-built tanks, the last of which SpaceX installed and ‘sleeved’ in mid-October, Starbase’s first orbital-class tank farm is a bit like the pad’s circulatory system and needs to store, chill, and distribute all the propellant needed for a rocket launch. To support Starship and Super Heavy, both the largest individual rocket stages and the largest integrated rocket ever built, its launch site and tank farm have to be equally immense. In classic SpaceX fashion, the company has strived to keep the costs of that tank farm low and its speed of construction high, resulting in a setup that’s fairly unique as far as launch pads go.
Perhaps nothing emphasizes the scale of Starship’s first orbital-class tank farm than the process of filling it with the supercool propellant and fluids its designed to hold.
In mid-September, SpaceX began delivering cryogenic fluids to Starbase’s orbital tank farm for the first time ever. Instead of propellant, dozens of tanker trucks delivered liquid nitrogen to one or two of the farm’s tanks between mid-September and mid-October. Altogether, around 40-60 truckloads was delivered – only enough to partially fill one tank. That liquid nitrogen also appeared to be piped into two of the farm’s three liquid oxygen tanks, meaning that it may have only been used to clean and proof test them.
Combined, the farm’s seven main tanks should be able to store roughly 2400 tons (5.3M lb) of liquid methane (LCH4), 5400 tons (12M lb) of liquid oxygen (LOx), and 2600 tons (5.7M lb) of liquid nitrogen (LN2). LCH4 and LOx are Starship’s propellant, while LN2 is needed to ‘subcool’ that propellant below its boiling point, significantly increasing its density and the mass of propellant Starships can store.
In recent weeks, LN2 deliveries have picked back up at the orbital tank farm, suggesting that more tanks are being cleaned and proofed. SpaceX may have also begun filling one or both of the farm’s dedicated LN2 tanks, though it’s hard to say for sure. More importantly, around October 17th, SpaceX began filling Starship’s orbital tank farm with liquid oxygen – real propellant – for the first time. Rather than a slow and cautious process, deliveries have streamed in almost daily ever since. As of November 4th, at least 74 tanker trucks have delivered LOx to the farm in 18 days.
Based on Department of Transportation (DOT) regulations that limit the gross weight of cryogenic tanker trucks to about 37 tons (~81,000 lb), each of those trucks has likely delivered around 20 tons (~45,000 lb) of LOx to Starbase. Altogether, that amounts to around 1500 tons (3.3M lb) delivered in less than three weeks – enough to fill about 80% of one of the farm’s three LOx tanks or a quarter of its total LOx storage capacity.
Based on data from AI-based tracker Starbase Deliveries, which can only count daytime deliveries, at least 134 tankers have delivered LCH4, LOx, or LN2 to Starbase’s orbital and suborbital launch sites between October 4th and November 4th – an average of 4.3 per day. At that rate, even if every delivery went to the orbital pad, it would take SpaceX nearly four months just to fill the orbital tank farm. Put simply, the facilities and logistics required to support even a single orbital Starship launch are gargantuan.
Tesla Robotaxi is among its biggest projects currently, but many have been quick to point out the fact that the company has definitely been slow to expand its fleet.
However, there is definitely a method to that madness. CEO Elon Musk answered several concerns during last night’s quarterly earnings call that some might have about that slow rollout of the Robotaxi suite, maintaining the company’s narrative on prioritizing safety and wanting to avoid injuries to anyone, including animals.
Musk said:
“With Robotaxi, our goals are very ambitious for Robotaxi, but we do need to be cautious about causing any accidents or causing any harm to anyone. Although there are, I think, 30,000 to 40,000 automotive deaths per year in the U.S. alone, most of those do not generate any press or maybe, you never really read about almost any of those. If we injure even one person, it’ll be worldwide headline news, and regulators will immediately clamp down on our activities.
We don’t want to injure anyone. We’re going as fast as humanly possible in scaling Robotaxi, but while trying to ensure that we do not harm anyone at all, and ideally do not even run over a pet. That’s really the constraint is we want to grow as fast as possible with Robotaxi without harm to anyone.”
Tesla has maintained an exemplary safety record with its Robotaxi suite, according to internal data. VP of AI, Ashok Elluswamy, said that the Robotaxi suite has driven more than 380,000 miles unsupervised without any incidents.

Analyst Colin Langan of Bank of America also pushed Tesla executives for answers regarding the company’s decision to add cities across several states with dozens of vehicles “as opposed to hundreds.”
Elluswamy said there’s a bigger advantage to do it the way Tesla has been because it ensures that its software stack “is a very general one:”
“The reason we have been expanding across different cities instead of just doubling down on a single city, is that we want to make sure that our stack is a very general one. It is a general one. We just want to both prove to ourselves and to other folks that it is working across a lot of different cities without too much effort per city. That’s what we see internally.”
In the past, we have written about Tesla’s decision to be incredibly conservative with its Robotaxi rollout, especially with the incredibly small fleet size compared to competitors. However, there really is not a price anyone can put on safety for those utilizing the platform or pedestrians, so what Tesla is doing is justified.
A year into the Robotaxi program being active, Tesla has made major strides, but many investors and fans would like to see the fleet expand as quickly as the program has to other cities and states.

Tesla Semi finally has an FSD timeline and it’s waiting on the Cybercab
Elon Musk told investors Semi self-driving should start working by early 2027, per today’s earnings.
During Wednesday’s’ Tesla Q2 earnings call, an analyst asked Elon Musk when Tesla would look at autonomy for the Semi. His answer set a real timeline for the first time, noting that self-driving on the Tesla Semi is expected to start working “around the end of this year or early next year”.
Musk framed the delay as a matter of priority, not capability. Tesla’s self-driving team is currently focused on Model 3, Model Y, and Cybercab, the vehicles that make up the overwhelming majority of Tesla’s fleet. Since Semi trucks on the road remain a small fraction of that total even after the recent Nevada factory ramp, Musk said it made more sense to keep the software team’s attention on what he called “the march of nines of safety” for the higher volume vehicles first. Autonomous Semi development is “taking a bit of a backseat for the next six months or so,” he said, before adding that it “will definitely be working next year and in time for the scale-up to high production of the Tesla Semi.”
Tesla Semi’s official battery capacity leaked by California regulators
The timeline lines up with what’s already been showing up on public roads. In June, a Tesla Semi was spotted in Sunnyvale wearing a full validation rig, the same rooftop sensor array Tesla mounts on vehicles ahead of an FSD milestone.
A second unit was seen near Fremont days later with a matching camera suite and lens washers. Separately, Tesla analyst Nic Cruz Patane posted video this month of the production Semi’s exterior camera array, ten AI4 based units built directly into the truck rather than added later.

Musk also gave the reason autonomy on the Semi matters in the first place, a persistent shortage of qualified truck drivers. “There is a really serious shortage of truckers,” he said on the call, framing a self-driving Semi as important both for addressing that shortage and for improving safety and comfort for the drivers running the truck today.
The timing also tracks with the Semi’s production reality. Tesla’s Q2 shareholder letter, dropped language promising the Semi would reach volume production this year. Musk pointed to 4680 battery cell output as the near-term constraint on Semi and Cybercab production. A software timeline landing in early 2027 gives Tesla’s autonomy team room to work while the hardware ramp catches up behind it.
It’s worth nothing that this isn’t necessarily a promise the Semi ships driverless next year. Musk’s own language, self-driving “working” by early 2027, describes internal validation catching up to hardware already riding on every production truck, not a public unsupervised rollout.
Tesla (NASDAQ: TSLA) reported its earnings for the first quarter of 2026 on Wednesday afternoon. Here’s what the company reported compared to what Wall Street analysts expected.
The earnings results come after Tesla reported a massive beat on vehicle deliveries for the second quarter, delivering 489,126 vehicles and building 451,758 cars during the three-month span.
This was a major shock for those on Wall Street as they anticipated somewhere around 400,000 deliveries for the quarter, and showed Tesla still has plenty of demand for its vehicles around the world and in the U.S. despite losing the $7,500 EV Tax Credit last year.
Tesla Q2 2026 Earnings Results
- Non-GAAP EPS – $0.33 reported vs. $0.53 expected
- Revenues – $28.236 billion reported vs. $26.4 billion expected
- Free Cash Flow- -$1.092B
- Profit -$ 4.751B
Tesla (beat/missed) analyst expectations, so the market response to the company’s quarter is what we will look for next.
Tesla shares closed today down just over 1 percent, trading at $374.01.
In the past, it has been anyone’s guess with what Tesla shares will do after they report earnings. Strong quarters have resulted in sharp drops, while lackluster quarters have seen the stock shoot up considerably.
Tesla will hold its Q2 2026 Earnings Call in about 90 minutes at 5:30 p.m. on the East Coast. Remarks will be made by CEO Elon Musk and other executives, who will shed some light on the investor questions that we covered earlier this week.
