SpaceX installs second Starship-derived fuel tank at orbital launch pad

This is getting out of hand, now there are two of them! (NASASpaceflight - bocachicagal)

For the second time in two weeks, SpaceX has rolled a ‘Starship-derived’ propellant tank to the next-generation rocket’s first orbital launch pad, continuing a recent burst of construction activity.

Precisely two weeks ago, SpaceX rolled the first of those massive ground support equipment (GSE) propellant tanks the 1.5 miles from its Boca Chica rocket factory to a nearby launch complex. Built with the same parts, facilities, and equipment as flightworthy Starship prototypes, SpaceX’s plans to build grounded storage tanks out of rocket parts went from a complete surprise to initial hardware delivery in less than two months.

Two weeks later, SpaceX has already completed the second of at least seven similar or identical tanks that should be able to store enough propellant for two back-to-back orbital Starship launches – and a third ‘GSE’ tank is just a week or so behind it.

As previously discussed on Teslarati, SpaceX’s decision to use a literal rocket factory to build custom propellant storage tanks is surprisingly revealing with a few reasonable assumptions in place.

SpaceX is effectively taking interchangeable Starship parts, slightly tweaking a handful of them, 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.

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.

Aside from potentially being dirt-cheap bulk storage tanks that all but guarantee SpaceX can produce Starship and its Super Heavy boosters for pennies on the dollar of any other rocket in history, SpaceX is quickly demonstrating that it can build a lot of them – and quickly. Parts of Starship prototypes SN17 through SN20 and Super Heavy boosters BN2 and BN3 continue to slowly trickle out of SpaceX’s factory and Starship SN16 is steadily progressing towards completion to take over wherever SN15 leaves off.

However, at least a majority of SpaceX’s focus appears to be set on mass-producing propellant storage tanks as quickly as possible in order to prepare Starship’s orbital launch pad – deep into construction – for flight tests involving Super Heavy. Just last month, following a sourced report from NASASpaceflight.com, CEO Elon Musk confirmed that SpaceX intends to attempt Starship’s first launch on a Super Heavy booster as early as July 2021 – just three months from now.

For obvious reasons, the odds are firmly stacked against SpaceX attempting Starship’s first orbital launch mere months from now, though such an attempt would still be extremely impressive if it happens in 2021 at all. To even attempt that extraordinarily ambitious feat, SpaceX will have to complete at least a barebones ‘rough draft’ of its planned orbital launch complex, including at least four Starship-style GSE tanks.

Towards that end, GSE tank #3 (GSE-3) is already more than half complete and parts of GSE-4 are in work, likely meaning that SpaceX will have enough installed propellant storage capacity for orbital Starship launch attempts less than a month from now. It remains to be seen if SpaceX will power through tanks 5 through 7 after 3 and 4 are complete, or if the focus will shift back to Starship and Super Heavy prototype production.

Either way, SpaceX is wasting no time constructing a brand new super heavy-class launch pad and a tank farm the likes of which has never been seen before. For now, we’ll have to wait and see how long it takes Starship and Super Heavy to catch up.

Tesla silences Robotaxi turn signals in sweeping but polarizing change

Published

on

Tesla has started rolling out a broader change to the ride experience for its Robotaxi fleet by silencing turn signals, but the change is certainly polarizing.

Tesla has generally made it clear that its purpose-built ride-hailing platform, Robotaxi, will cater to the rider in nearly every way possible. This includes having climate preferences, music, and other personal settings loaded up in the car as the rider enters.

But Tesla is taking it a step further by muting turn signal chimes altogether, a change that appears to be a way to make the ride more peaceful:

However, there are a handful of people who are not thrilled about this change. Turn signals are a conditioned part of the human mind for those who ride in a car regularly.

Taking a turn without one feels strange and odd, and not hearing it click while activated could set off some alarms for riders, who might use the noise as confirmation that other drivers know of their intention to turn.

Turn signal noises are still audible in customer cars, so if you use FSD in your personal vehicle, you will still hear the turn signal.

The move is certainly one that is unique, but not one that separates it from other ride-sharing services. In a normal car, the clicking sound confirms to the driver that the blinker is active. In a fully driverless Robotaxi, that feedback serves no purpose for passengers, other than peace of mind.

Tesla Full Self-Driving v14.3.6 review: a rare regression, but some bright spots

Published

on

Tesla released Full Self-Driving version 14.3.6 last week, and after what was potentially one of the best FSD releases in v14.3.5, there has been a bit of a regression. While there are some bright spots, the changes made to v14.3.6 seem to have backtracked some behaviors.

Overall, it is hard to really complain about FSD in any sense; it has revolutionized how I travel literally anywhere. According to my self-driving app, the last time I went a day without using it was 59 days ago.

However, I think it’s also important to recognize when things are just plain bad with FSD. There are times it does truly mind-boggling things, and I’ll dive into those here. Additionally, I only had these issues on local roads, not on highways. Highway operation, generally, is always incredible other than the occasional complaint about speed or left lane camping.

With those things being said, my personal experience may not represent others’ experiences. A handful of people have said they have had a similar experience on v14.3.6, while others have said it is more than normal.

Turning Hesitancy, Inaccuracy

I’ve noticed more inaccuracy turning into multi-lane stretches of road than in any version I can remember. I’ve had at least three instances of FSD turning into a stretch of roadway that has two or more lanes, and not selecting a lane confidently as it has in past versions.

Instead, the car will drive over one of the dashed road lines, and the steering wheel will jerk back and forth before picking the lane. It should be said that it has always picked the correct lane when choosing based on the navigation, but it is still very indecisive. The steering wheel jerking is reminiscent of some of the later versions of v13.

I admit I really hate to see the steering wheel jerking come back. However, I think when Tesla releases v14.3.7, it won’t be present. When there are occurrences of it in FSD versions, it is usually resolved by the following release.

FSD Disregards Manual Turn Signals

This is my biggest bone to pick with FSD other than Navigation issues, but this one seems like it would be such an easy fix.

If Tesla is going to put the word “Supervised” on the end of “Full Self-Driving,” then when I tell the car to do something, it should do it. If I input an increase in speed by pressing the accelerator, the car will immediately respond. It does not disregard my input because it feels it is traveling at the right speed.

FSD should never disobey and turn off turn signals that the driver inputs. Trying to direct the car into the correct lane, I had initiated the left turn signal not once, not twice, but three times, with the car turning it off all three times and continuing in a lane that would end in just one block. The only solution at this point would be to zipper merge.

This goes back to the fact that self-driving’s biggest bottleneck might be rider preference. A zipper merge might have been more than reasonable, might have saved me time that I spent sitting through an additional light cycle, and might be something many drivers would do. I was in no hurry, I traditionally do not try to zipper merge because it feels inconsiderate, and lastly, the car should have just followed my input.

This caused me to disengage and drive manually the rest of the way home. Sometimes I just do not need FSD to try to pass every car it can at intersections.

Bird Braking is a Thing of the Past

The big complaint with recent versions of Full Self-Driving has been what we’ve coined as “bird braking,” which is when the car will brake suddenly as a bird flies past.

There have been zero issues with this so far in v14.3.6, which is an excellent improvement.

FSD Might Already Be Taking Note of Driver Preferences

Another thing I have noticed over the past few days is that v14.3.6 seems to already be taking my preferences with navigation into account.

This is something that is supposed to be rolling out with the Summer Update, but I have a hunch it’s already present and might have been included in this v14.3.6 build. On Friday, FSD pulled into an entrance to a local convenience store that it had never attempted to go into before.

Typically, I manually pull into this entrance because it avoids heavy cross traffic at the main entrance. FSD has always chosen that congested main entrance.

Additionally, FSD has pulled into my assigned parking spot at my townhouse community on multiple occasions with this release. This is something that used to happen ocassionally, but not consistently.

It also navigated back to the same convenience store last night, drove through crazy cars scrambling to gas pumps, navigated out of the parking lot correctly, drove me home, and, once again, parked in my assigned spot.

As previously stated, this release just seems to have a few things that need to be brought to Tesla’s attention, and also to make others who use FSD aware of some things that I’ve experienced. I look forward to the next release that will remedy these issues, just as Tesla has always done in the past.

Musk’s massive Terafab project will get final location soon

Elon Musk’s massive Terafab project, which will be the first true conglomeration between each of his major entities, is set to get its final location soon, the CEO said on Tesla’s recent earnings call.

“The Terafab, we expect to announce a location soon, and provide more details about our plans in that regard. We’ll leave that to the product, the launch announcement rather than try to squeeze it into an earnings call,” Musk said last Wednesday.

Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry

Terafab was announced by Musk back in March and was essentially a massive, vertically integrated semiconductor manufacturing project that would provide all the chips the three companies needed for their AI initiatives without needing third-party companies.

The plant will produce over 1 terawatt of AI compute each year, and will help back up projects like Optimus, Full Self-Driving, and other AI-based projects that Musk’s companies are working on.

In April, less than a month after the project was launched, Intel announced it would join the project, contributing manufacturing expertise and consulting to Terafab as a whole. Intel is one of three chip manufacturers that produce sub-5 nanometer chips at scale. TSMC and Samsung are the other two.

However, there was no true indication of where Terafab would end up, but most believe it will likely be somewhere in Texas. Business Insider has reported that SpaceX plans to build out Terafab in Grimes County, Texas, but this is unconfirmed.

Musk confirmed recently that it would not be on Giga Texas property, as it is simply too large.

Terafab holds much of Musk’s grand ambitions for the future within its construct. It holds so much responsibility for the future and the biggest projects that Musk’s companies can imagine.

“I think this is a very big announcement and it deserves to have its own day in the spotlight and not be squeezed into an earnings call,” he said. “I do think Terafab is going to be an amazing initiative and a necessary one, and one without which we will be constrained in our ability to scale Optimus production, because we simply won’t have enough AI chips.”

He continued by stating that Terafab is necessary for scaling Optimus, which Musk said could be the biggest product of any kind of all time. “It’s crucial to solve that, and we’ll have to solve memory, logic, and packaging in order to scale Optimus.”
