SpaceX is building launch pad tanks out of Starship parts and that’s a big deal

SpaceX has begun installing the first of numerous propellant storage tanks at its first orbital South Texas launch facilities – a mostly ordinary and expected step made extraordinary by the fact that those tanks will be built out of Starship parts.

Labeled “GSE” for Ground Support Equipment, the first signs of those self-built storage tanks began appearing at SpaceX’s Boca Chica Starship factory less than two months ago in mid-February. A matter of weeks later, the first of those SpaceX-brand cryogenic storage tanks is off to the launch site for installation (and insulation) while at least two more tanks are well on their way to completion.

While a few ground starge tanks may look like a distraction in the scope of a program tasked with building the world’s largest (and fully reusable) rocket, the existence of those tanks is far more significant than it might initially appear.

Simply put, rocket propellant storage – even for extremely cold cryogenic liquids like those that SpaceX uses – is a thoroughly solved problem. Numerous commercial vendors exist and industrial demand for practically identical tanks is far higher, further lowering commercial tank costs even for those with niche use-cases thanks to economies of scale. For SpaceX’s purposes, major discounts could like be secured given that the company would need to purchase around three to four-dozen commercial-off-the-shelf (COTS) 100,000 gallon tanks to supply a launch pad with enough commodities for two back-to-back launches of Starship and Super Heavy.

That initial launch capability – which SpaceX appears to be working towards – would likely allow the company to start orbital refueling test flights (and Starlink launches, perhaps) immediately after completion. However, that initial capability wouldn’t suffice for ambitious missions to Mars, the Moon, or higher Earth orbits; where one Starship would need to be rapidly refueled with 3-10+ tanker launches. A launch facility capable of supporting 5-10 back-to-back launches (optimally just a few hours apart) would require many times more propellant storage.

The point is that for the initial target of two (or so) launches between commodity resupply, SpaceX could likely acquire the few dozen new storage tanks it would need for a few million dollars apiece for a total cost likely between $50M and $100M. Instead, SpaceX has decided to design and build its own propellant storage tanks. Even more significantly, the GSE tanks SpaceX has already begun building appear to be virtually identical to Starships.

In other words, SpaceX is effectively taking identical rocket parts, slightly tweaking a handful of those parts, and turning what could have been a rocket into a propellant storage tank. This is significant because relative to all other rockets in history, even including SpaceX’s own Falcon 9 and Heavy, building storage tanks with unchanged rocket parts on a rocket assembly line would be roughly akin to hiring Vincent van Gogh to paint lane lines.

Ever since Elon Musk made the radical decision to switch from composite structures to stainless steel, Starship has always aimed to be radically different than any large rocket before it. Crucially, by using commodity steel, the CEO imagined SpaceX would be able to build Starships fairly easily and for pennies on the dollar next to even SpaceX’s exceptionally affordable Falcon 9. In the last 18 months, it’s become apparent that SpaceX has built a factory capable of churning out one or two massive steel rockets per month and is willing to consign at least four or five of those Starship prototypes to all-but-guaranteed failures for the sake of data-gathering and iterative improvement.

Technically, the most logical conclusion would be that Musk was right and that SpaceX has quickly developed the ability to build steel rockets larger than any other launch vehicle on Earth for perhaps just $5M or less apiece. However, SpaceX is also raising on the order of $1-2B in venture capital annually, so they could technically afford to shoulder the cost of extremely expensive Starship prototypes if the company was confident that there was a path to cut those costs and reach the targets needed for the rocket to make economical sense.

Now, the existence of self-built propellant storage tanks virtually identical to flightworthy Starship airframes all but guarantees that SpaceX is already building Starships for a few million dollars each – and possibly much less. More than a year ago, Musk said that SpaceX was already building the Raptor engines that will power Starship and Super Heavy for less than $1M apiece and was working to mass-produce a simpler variant for less than $250,000. Beyond engines and primary structures, Starship hardware is fairly simple and ranges from Tesla-derived motors, basic flaps, and landing legs to off-the-shelf pressure vessels (COPVs) and wiring. SpaceX has managed that extraordinary cost-efficiency despite the fact that Boca Chica is still nowhere close to the level of volume production Musk is aiming for, meaning that there are still far more efficiencies waiting to be realized.

For now, with virtually no retooling and the exact same assembly line, SpaceX’s South Texas rocket factory is busy churning out massive launch pad tanks – one of which is already preparing for installation while another two speed towards completion. All told, SpaceX appears to be preparing foundations for seven 9m-wide (30ft), 27.5m-tall (90ft) Starship-derived tanks that should be capable of storing ~2200 tons (4.9 million pounds) of subcooled liquid methane in three tanks and ~7300 tons (16.1 million pounds) of liquid oxygen in the other four tanks – enough for two orbital Starship launches.

SpaceX opens up free Starlink service for those impacted by Hurricane Melissa

SpaceX is opening up its internet service, Starlink, to those impacted by Hurricane Melissa, as it made landfall in Jamaica and the Bahamas as a Category 5 storm.

Hurricane Melissa is expected to reach wind speeds of over 165 MPH over the next few days as it extends out into the Atlantic Ocean by Thursday and Friday.

Citizens in Jamaica and the Bahamas have been preparing for the storm for the past week, getting necessary goods together and preparing for the massive storm to arrive. It finally did yesterday, and the first images and video of the storm are showing that it could destroy many parts of both countries.

Starlink is now being opened up for free until the end of November for those impacted by the storm in Jamaica and the Bahamas, SpaceX announced today:

It is a move similar to the one the company made last year as Hurricane Helene made its way through the United States, destroying homes and property across the East Coast. SpaceX offered free service for those impacted by the destruction caused by the storm.

The free Starlink service was available until the end of 2024.

Elon Musk’s companies have also made similar moves to help out those who are impacted by natural disasters. Tesla has offered Free Supercharging in the past, most notably during the California wildfires.

One major advantage of Starlink is that it is available for use in situations like this one, where power might be required to operate things like a modem and router.

Internet access is a crucial part of survival in these situations, especially as it can be the last leg some stand on to get in touch with emergency services or loved ones.

Tesla board chair reiterates widely unmentioned point of Musk comp plan

Tesla Board Chair Robyn Denholm appeared on Bloomberg TV this morning to discuss the current status of CEO Elon Musk’s compensation plan, and used the opportunity to reiterate a widely unmentioned key point of the entire package.

Critics of the proposed pay package, which would pay Musk $1 trillion if he completes every tranche, routinely cite the sheer size of the payday.

Of course, many skeptics leave out the fact that he would only get that money if he were able to generate eight times the value the company currently has.

Tesla gains massive vote of confidence on compensation plan for Elon Musk

For Musk, it might have a little bit to do with money, but that is likely a very small percentage point of why the compensation package is being offered to him. He has reiterated that it is more about voting control and overall influence, especially as Tesla dives into robotics.

He said during the Q3 Earnings Call:

“My fundamental concern with regard to how much voting control I have at Tesla is if I go ahead and build this enormous robot army, can I just be ousted at some point in the future? That’s my biggest concern. That is really the only thing I’m trying to address with this. It’s called compensation, but it’s not like I’m going to go spend the money. It’s just, if we build this robot army, do I have at least a strong influence over that robot army, not current control, but a strong influence? That’s what it comes down to in a nutshell. I don’t feel comfortable wielding that robot army if I don’t have at least a strong influence.”

Tesla shares the idea that Musk is a crucial part of the company, and without him being awarded the voting control he feels he deserves, he could leave the company altogether.

The company is very obviously feeling the importance of the upcoming vote, as it has advertised and pushed heavily for the comp plan to be approved, mostly to retain Musk.

Tesla Board Chair Robyn Denholm said today to Bloomberg TV that it is crucial shareholders understand it is not about Musk’s potential wealth, but more about his influence on company decisions:

“So firstly, it is a performance package, so he gets nothing if he doesn’t perform against the pretty audacious milestones that are part of the performance criteria that’s been outlined by the board in the performance package. So, I think rather than compensation, it’s actually about the performance and the goals that we have for the company as we move forward. And so, for me, it really is about making sure that investors understand that they actually get paid if he hits the milestones before he will…Elon’s been very public, including on last week’s earnings call, about the fact that it’s around the voting influence that he could have in future shareholder meetings as opposed to the economic interests.”

Musk is not an incredibly flashy person. He does not have crazy cars or a massive house to go back to. He spends a lot of his time working and sometimes even sleeps at his office inside the factory.

He recently said he “only has what is needed” because “material possessions were making him weak.”

The truth about Tesla ‘Mad Max’ mode from an actual user

Some people might see “Mad Max” as an extension of their daily driving.

For me, I did not see it that way. I saw it as a useful tool for certain situations, but it was certainly not something I could compare to my personal driving style.

But that does not mean that it’s wrong.

There have been many headlines about Tesla’s new “Mad Max” mode, but many of those writing about the “dangerous” and “controversial” mode have probably never used it.

As a writer, I write about topics I do not have firsthand experience with, but the job requires me to take a fair stance and report what is known. The problem is the nature of driving and driving modes, specifically, is subjective.

Some people might see “Mad Max” as an extension of their daily driving.

For me, I did not see it that way. I saw it as a useful tool for certain situations, but it was certainly not something I could compare to my personal driving style.

But that does not mean that it’s wrong.

NHTSA Probes Tesla Over “Mad Max”

Last week, the NHTSA launched a bit of a probe into Mad Max mode, requesting additional information on the Speed Profile and reiterating that the driver of the car is still required to be in ultimate control.

Tesla ‘Mad Max’ gets its first bit of regulatory attention

It’s important to keep the latter portion of that sentence in mind for the true thesis of this piece.

Now, it is no surprise to me that Mad Max garnered attention from regulatory agencies, as it is definitely a more spirited driving profile than the others.

Is Mad Max That Big of a Deal?

Regulatory agencies are responsible for keeping people safe, and it is important to note that their control is somewhat necessary. However, this type of drive mode is optional, requires the driver’s attention, and should be used responsibly for safe travel.

Playing Devil’s Advocate, how is Mad Max any different than the performance modes that some sports cars have? Because they require the driver to operate fully, and they are not semi-autonomous like Tesla can offer with Mad Max in Full Self-Driving (Supervised), are they safer?

The argument here really comes down to whether FSD is being used responsibly and correctly; any accelerated drive mode becomes more of a risk if the vehicle operator is not paying attention. This applies to any car company or drive mode they choose to use on their cars.

My Personal Experience with Mad Max

I have used Mad Max probably ten times since it rolled out to Early Access Program (EAP) members a few weeks ago.

I’ll admit: it did a lot of things I would never do driving a car manually. It passed people on the right. It was the fastest vehicle on the interstate, at least until I crossed into Maryland. Then, it seemed to be just another car on the road.

It drove quickly, and not so fast that I felt concerned for my safety, which I never feared for, but fast enough that, at certain points, I was concerned that a cop would pull me over. I never encountered that scenario, but I wouldn’t be surprised if it resulted in some tickets.

With that being said, I don’t particularly think I’d use Mad Max in more than a handful of applications: driving the Baltimore Beltway would be one instance, navigating traffic in Baltimore, Philadelphia, or Pittsburgh during heavy traffic, or cruising on I-95, where cars routinely are going 100 MPH, much faster than Mad Max would ever travel.

Is it too quick for me in residential settings? For me, yes. Is it faster than every human driving on those roads? Absolutely not. In my experience, it is quicker than some, slower than others, just like any other Speed Mode Tesla offers, even Sloth, which refuses to go over the posted speed limit.

I think it’s wrong to sit here and act as if Mad Max is some incredibly dangerous and life-threatening hazard. If a driver is uncomfortable with the maneuvers or speed, they do not have to use it. However, it is no different from how many other cars travel on the road; it is far from an anomaly.

Tesla FSD’s new Mad Max mode is getting rave reviews from users

With that being said, it will be interesting to see if the NHTSA does anything about Mad Max, whether it will require Tesla to “nerf” the Speed Profile, or remove it altogether. It’s also important to note that this is my personal experience with Mad Max, and what I’ve experienced might differ from others’.

I would love to hear your thoughts on how Mad Max has driven for you, or your impressions of it.
