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 discloses interesting collaboration partner for Supercharging

This BOXABL collaboration would be a great way to add a rest stop to a rural Supercharging location, and could lead to more of these chargers across the U.S.

Tesla disclosed an interesting collaboration partner in an SEC filing, which looks like an indication of a potential project at Supercharger sites.

Tesla said on Tuesday in the filing that it was entering an agreement with BOXABL to design and build a Micromenity structure. Simply put, this is a modular building, usually a few hundred square feet in size, and it has been seen at Superchargers in Europe.

In Magnant, France, Tesla opened a small building at a Supercharger that is available to all EV owners. There are snacks and drinks inside, including ice cream, coffee, a gaming console, and restrooms. It gives people an opportunity to get up and out of their cars while charging.

This building was not built by BOXABL, but instead by bk World Lounges. It is likely the final Supercharging stop before people get to Paris, as it is located 250 kilometers, or 155 miles, from the City of Light.

Magnant has 56 stalls, so it is a large Supercharging stop compared to most. The building could be a sign of things to come, especially as Tesla has opened up larger Supercharger stations along major roadways.

It is for just a single building, as the Scope of Work within the filing states “a comprehensive package for one Micromenity building.”

Superchargers are commonly located at gas stations, shopping centers, and other major points of interest. However, there are some stops that are isolated from retail or entertainment.

This BOXABL collaboration would be a great way to add a rest stop to a rural Supercharging location, and could lead to more of these chargers across the U.S.

Tesla has done a lot of really great things for Supercharging this year.

Along with widespread expansion, the company launched the “Charging Passport” this week, opened the largest Supercharger in the world in Lost Hills, California, with 168 chargers, opened the Tesla Diner, a drive-in movie restaurant in Los Angeles, and initiated access to the infrastructure to even more automakers.

Tesla CEO Elon Musk confirms Robotaxi safety monitor removal in Austin: here’s when

Musk has made the claim about removing Safety Monitors from Tesla Robotaxi vehicles in Austin three times this year, once in September, once in October, and once in November.

Tesla CEO Elon Musk confirmed on Tuesday at the xAI Hackathon that the company would be removing Safety Monitors from Robotaxis in Austin in just three weeks.

This would meet Musk’s timeline from earlier this year, as he has said on several occasions that Tesla Robotaxis would have no supervision in Austin by the end of 2025.

On Tuesday, Musk said:

“Unsupervised is pretty much solved at this point. So there will be Tesla Robotaxis operating in Austin with no one in them. Not even anyone in the passenger seat in about three weeks.”

Musk has made the claim about removing Safety Monitors from Tesla Robotaxi vehicles in Austin three times this year, once in September, once in October, and once in November.

In September, he said:

“Should be no safety driver by end of year.”

On the Q3 Earnings Call in October, he said:

“We are expecting ot have no safety drivers in at least large parts of Austin by the end of this year.”

Finally, in November, he reiterated the timeline in a public statement at the Shareholder Meeting:

“I expect Robotaxis to operate without safety drivers in large parts of Austin this year.”

Currently, Tesla uses Safety Monitors in Austin in the passenger’s seat on local roads. They will sit in the driver’s seat for highway routes. In the Bay Area ride-hailing operation, there is always a Safety Monitor in the driver’s seat.

Three weeks would deliver on the end-of-year promise, cutting it close, beating it by just two days. However, it would be a tremendous leap forward in the Robotaxi program, and would shut the mouths of many skeptics who state the current iteration is no different than having an Uber.

Tesla has also expanded its Robotaxi fleet this year, but the company has not given exact figures. Once it expands its fleet, even more progress will be made in Tesla’s self-driving efforts.

SpaceX reportedly mulling IPO, eyeing largest of all time: report

“I do want to try to figure out some way for Tesla shareholders to participate in SpaceX. I’ve been giving a lot of thought to how to give people access to SpaceX stock,” Musk said.

SpaceX is reportedly mulling an initial public offering, eyeing what would be the largest valuation at the time of availability of all time, a new report from Bloomberg said on Tuesday.

It is one of many reports involving one of Elon Musk’s companies and a massive market move, as this is not the first time we have seen reports of an IPO by SpaceX. Musk himself has also dispelled other reports in the past of a similar nature, including an xAI funding round.

SpaceX and Musk have yet to comment on the report. In the past, untrue reports were promptly replied to by the CEO; this has not yet gained any response, which is a good sign in terms of credibility.

However, he said just a few days ago that stories of this nature are inaccurate:

“There has been a lot of press claiming SpaceX is raising money at $800B, which is not accurate. SpaceX has been cash flow positive for many years and does periodic stock buybacks twice a year to provide liquidity for employees and investors. Valuation increments are a function of progress with Starship and Starlink and securing global direct-to-cell spectrum that greatly increases our addressable market. And one other thing that is arguably most significant by far.”

Musk has discussed a potential IPO for SpaceX in recent months, as the November 6 shareholder meeting, as he commented on the “downsides” of having a public company, like litigation exposure, quarterly reporting pressures, and other inconveniences.

Nevertheless, Musk has also said he wants there to be a way for Tesla shareholders to get in on the action. At the meeting in early November, he said:

“I do want to try to figure out some way for Tesla shareholders to participate in SpaceX. I’ve been giving a lot of thought to how to give people access to SpaceX stock.”

Additionally, he added:

“Maybe at some point., SpaceX should become a public company despite all the downsides of being public.”

Musk has been historically reluctant to take SpaceX public, at times stating it could become a barrier to colonizing Mars. That does not mean it will not happen.

Bloomberg’s report cites multiple unidentified sources who are familiar with the matter. They indicate to the publication that SpaceX wants to go public in mid-to-late 2026, and it wants to raise $30 billion at a valuation of around $1.5 trillion.

This is not the first time SpaceX has discussed an IPO; we reported on it nine years ago. We hope it is true, as the community has spoken for a long time about having access to SpaceX stock. Legendary investor Ron Baron is one of the lucky few to be a SpaceX investor, and said it, along with Tesla, is a “lifetime investment.”

The primary driver of SpaceX’s value is Starlink, the company’s satellite internet service. Starlink contributes 60-70 percent of SpaceX’s revenue, meaning it is the primary value engine. Launch services, like Falcon 9 contracts, and the development of Starship, also play supporting roles.
