SpaceX’s first two Super Heavy boosters making good progress towards test debuts

Published

on

SpaceX is making good progress on Starship’s first two Super Heavy boosters, both of which could potentially be ready for their first major test campaigns before the end of the year.

On November 19th, some ten weeks after the process began, SpaceX craned Super Heavy B5’s methane (LCH4) tank on top of its oxygen (LOx) tank, marking the end of major structural assembly for the 69m (~225′) tall booster. A team of welders has since been working around the clock to weld the two tanks together and complete a transfer tube that routes methane propellant down through B5’s oxygen tank.

Two days prior, CEO Elon Musk shared a photo of SpaceX’s other Super Heavy booster (B4) which has been slowly progressing towards test readiness for more than three months. It’s unclear why SpaceX has been so sluggish to prepare Super Heavy B4 for testing but with B5 finally approaching the finish line, the company will soon find itself in a position where it will need to decide which booster to proceed with towards the program’s near-term end goal: the first orbital Starship test flight.

Once Booster 5’s two halves are welded together, only a few things will set it and Booster 4 apart. In recent weeks, SpaceX’s slow progress on Super Heavy B4 relented a bit as technicians began closing out the booster’s raceway (a conduit for plumbing, wiring, and avionics) with basic covers. More importantly, SpaceX also began reinstalling Raptor engines and installing heat shielding around those engines for the first time. In the photo Musk published on November 17th, that heat shield is easily visible and there are signs that it will ultimately enclose the entire outer ring of 20 Raptor Boost engines above their nozzles.

Once complete, that shield will theoretically protect each engine’s nest of sensitive plumbing and wiring during static fires; ascent, boostback, and landing burns; and – most importantly – reentry. Unlike Falcon boosters, which always perform a ~30-second, three-engine ‘reentry burn’ to slow down and cushion the blow of reentry heating, SpaceX plans to recover steel Super Heavy boosters without reentry burns. In theory, that should making booster recovery more efficient, allowing another dozen or so tons of propellant to go towards sending Starship to orbit instead of landing.

As of November 17th, SpaceX has reinstalled all 29 Raptor engines on Booster 4, partially finished the outer ring of Raptor heat shields, and set the stage for more heat shielding around its 9 center engines and the gap between those inner and outer Raptors. Shielding the Raptor Center engines in a way that still seals off Super Heavy’s aft will be even more challenging given that all nine need to be able to freely gimbal to vector their thrust, while the outer ring of 20 Raptor Boost (RB) engines are fixed in place. At pace of work established over the last few months, it will likely take SpaceX several more weeks to finish that heat shield and install seven ‘aerocovers’ over racks of sensitive equipment installed around Booster 4’s base.

Super Heavy Booster 5, on the other hand, has taken a slightly different path through assembly. Unlike Booster 4, which first rolled out as little more than a giant steel tank with Raptors half-installed, SpaceX appears to have installed most of Booster 5’s external plumbing, wiring, equipment racks, and maybe even the start of its Raptor heat shield during assembly instead of after. Perhaps as a result, SpaceX has taken more than ten weeks to stack Booster 5 versus 2.5 weeks for Booster 4. But given that Booster 4 still doesn’t appear to be complete some 18 weeks after its assembly began, there’s a chance that Booster 5 will ultimately take 4-6 weeks less to reach initial test readiness.

If SpaceX does complete Super Heavy B5 well ahead of B4’s schedule, it will soon find itself with two test-ready Starship boosters but only one orbital-class stand with which to test them, potentially forcing the company to make some interesting decisions.

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.
