Despite the spectacular demise of a full-scale prototype just days ago, a senior SpaceX engineer and executive believes that Starship could still be ready for its first orbital launch attempt before the end of the year.

Even if the first launch attempt fails, that milestone – if realized – would be one of the single biggest upsets in the history of spaceflight, proving that Saturn V-scale orbital-class rockets can likely be built in spartan facilities with common materials for pennies on the dollar. Much like Falcon 1 suffered three launch failures before successfully reaching orbit, there’s a strong chance that Starship’s first shot at orbit will fall short, although each full-up launch failure would likely cost substantially more than the current prototypes being routinely tested to destruction in South Texas.

Most recently, what CEO Elon Musk later described as a “a minor test of a quick disconnect” went wrong in a spectacular fashion, causing a major liquid methane leak that subsequently ignited and created a massive explosion. Although Starship SN4 did technically complete its fifth Raptor engine static fire test just a minute or so prior, the ship and its immediate surroundings were obliterated by the violent explosion, leaving little more than steel shrapnel and the broken husk of a launch mount behind. It’s in this context that one of SpaceX’s most levelheaded, expert executives believes that an orbital launch could still happen this year.

While Starship SN4’s demise and the continued possibility of the ship’s orbital launch debut occurring less than seven months from now may seem at odds with each other, that’s actually just a side effect of the approach SpaceX has always taken when developing brand new rockets and spacecraft. Following the lead of the scrappy teams that used the exact same methods to design, test, and fly the massive Saturn rockets that took humans to the Moon, SpaceX has always preferred to learn by doing.

Inevitably, testing minimum viable products to their limits will lead to failures, but those failures are actually extremely valuable so long as they are extensively analyzed and learned from. That’s exactly what SpaceX has been doing for the last six or so months with full-scale Starship prototypes: building, testing, failing, and improving in an unending cycle. Built slowly with inferior methods, Starship Mk1 almost immediately during its first pressure test in November 2019. SpaceX took that failure, extracted all the insight it could, and dramatically improved its production methods before completing Starship SN1 barely three months later.

Starship SN4 marked the most recent failure during SpaceX’s hardware-rich development program.

Prior to SN1, SpaceX built and tested two stout test tanks to failure, ultimately achieving pressures of ~8.5 bar – sufficient for reliable human spaceflight – with the second tank on January 30th, 2020. On February 28th, Starship SN1 was unfortunately destroyed by a faulty ‘thrust puck’ (Raptor engine mount). Just 10 days later, SpaceX successfully tested a third ad-hoc test tank, proving that it had already rectified the engine section design flaw. Hardware isn’t always the only problem, however, and Starship SN3 was destroyed by human operator error during a cryogenic proof test on April 3rd.

Starship SN4 was completed and moved to the launch pad less than a month later and began testing just a few days after that, quickly racking up milestones as it became the first full-scale prototype to pass cryogenic proof testing, perform a wet dress rehearsal (WDR) with real propellant, fire up a Raptor engine, and complete a more ambitious cryogenic pressure test. Prior to the ground systems fuel leak that killed it, SN4 was possibly just days away from attempting the inaugural flight of a full-scale Starship prototype.

With Starship SN4 now steel confetti, Starship SN5 – effectively complete – will likely take over where its predecessor left off, heading to the launch pad within the next week or so before attempting a cryogenic pressure test and Raptor static fire to clear it for flight. Per Koenigsmann, that flight debut could come just a few weeks from now – likely before the end of June if replacement ground equipment can be quickly completed. If Starship SN5 survives that hop debut, it may ultimately be upgraded with a nosecone, flaps, and two additional Raptor engines to perform a dramatic 20 km (~12 mi) flight, capped with a supersonic skydiver-style reentry and landing test.

Once that capability has been successfully demonstrated, Super Heavy development and orbital Starship operation and reentry are the next critical hurdles. If Koenigsmann is correct, it’s safe to say that the first fully heat-shielded Starships and the beginnings of the first one or several Super Heavy booster prototypes will begin to appear in South Texas within the next few months.

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.”

Elon Musk reveals SpaceX performed secret Starship test on Flight 13

SpaceX performed a secret test on a specific portion of Starship with its recent 13th test flight last week, CEO Elon Musk revealed.

Starship’s 13th test flight took place last Friday, and in many aspects, it was one of the most overwhelmingly successful launches in the project’s history.

All of the mission objectives were met without incident, both the Super Heavy Booster and Ship managed to perform safe splashdowns in the Gulf of America and the Indian Ocean, respectively, and the deployment of Starlink satellites came and went without any complications.

However, there was more on the agenda for SpaceX with Flight 13. Musk revealed an internal test of the ship’s heat shield tiles, as the space exploration company wanted to push them to the limits after previous issues.

Many noticed that Starship’s initial launch seemed to be more accelerated than normal, and that was not a mistake. Musk revealed that SpaceX decided to give Flight 13 an intentionally aggressive acceleration rate in an effort to test how well the tiles would remain attached to the ship:

SpaceX had issues with some of the heat shield tiles remaining attached early on in the Starship program. The first six test flights presented some kind of anomaly with them, so the company’s big focus with them was to figure out a way to keep them intact through the duration of the flight.

Things truly improved as Flight 10 showed that ceramic tiles generally stayed attached to the ship far better due to refined attachment, as SpaceX utilized pins instead of adhesives. Flights 10 through 13 truly showed some clear progress with the heat shield tiles, and this latest test seems to be where some real progress was noticed, especially by Musk.

The 13th Starship launch last Friday was the second with Starship V3, SpaceX’s latest and greatest iteration of the spacecraft. Goals and ambitions are getting even grander as the project continues to progress. Musk has already hinted that SpaceX will likely try to catch Starship with Flight 14.
