SpaceX almost loses Falcon 9 booster at sea

Published

on

After more than a week at sea, the SpaceX Falcon 9 booster responsible for the company’s 100th successful landing finally returned to port on Wednesday, revealing that it nearly toppled into the sea during the recovery process.

Falcon 9 B1069 completed its first launch without issue early on December 21st, carrying a reused Cargo Dragon capsule into space and sending it on its way towards orbit and the International Space Station (ISS). Nine minutes after liftoff, it touched down on drone ship Just Read The Instructions (JRTI) without any apparent issue, more or less hitting the platform’s painted bullseye. While it’s difficult to determine with certainty, B1069 appeared to be in fine condition after landing, standing roughly straight up with all nine Merlin 1D engines well above the drone ship’s deck.

That was decidedly not the case when the once-flown Falcon 9 booster finally sailed into Port Canaveral eight and a half days later.

There remains plenty of ambiguity about how exactly things transpired after the landing but when B1069 was finally within eyeshot, the booster was significantly damaged, riding low on all four legs, inches away from falling off the drone ship’s deck, and only partially attached to the “Octagrabber” robot tasked with securing it. Based on photos of the damaged rocket taken by Teslarati photographer Richard Angle, most or all of B1069’s nine Merlin 1D (M1D) engines suffered likely irreparable damage to their fragile bell nozzles.

From the ragged nature of the damage to those nozzles, it appears that B1069 somehow fell on top of the drone ship’s Octagrabber robot during or after its recovery attempt, as the creases would be far cleaner if the booster had merely landed hard and pressed its M1D nozzles against the deck. But a very short fall onto Octagrabber still doesn’t quite explain the apparent damage to one of the booster’s landing legs or the fact that it’s sitting lower to the deck than usual – both potentially indicative of a hard landing.

What is clear, though, is that SpaceX struggled to secure the rocket shortly after its first landing. Per the CRS-24 webcast, B1069 landed just shy of dead center. Likely as a result of poor sea conditions, SpaceX was unable to quickly grab the booster with Octagrabber, which uses giant clamps and its own weight to hold Falcon first stages in place. B1069 then clearly slid around drone ship JRTI’s deck at the whim of the ocean. Before SpaceX could secure it, the booster slammed into the side of the drone ship hard enough to partially flatten a steel safety barrier that runs along its port and starboard beams – a barrier specifically put in place to prevent wayward boosters from sliding off the deck.

Thankfully, above all else, there is no obvious reason that SpaceX won’t be able to repair the damage that was wrought. Replacing all nine of B1069’s engines will heavily delay the booster’s return to flight and probably singlehandedly cost SpaceX at least $5-10 million, but that cost is still far less than scrapping it and building a new booster. Aside from that, it’s possible that B1069’s fall will preclude strict customers like NASA or the US military from reusing the booster to launch their payloads, which the booster would have otherwise been a shoo-in for with just a single NASA launch on its record.

While CRS-24 and B1069’s dramatic return was SpaceX’s last launch and booster recovery of the year, the company did safely recovery several other boosters sans damage in the days and weeks prior. On December 14th, Falcon 9 B1061 was spotted being craned onto dry land after its fifth launch – NASA’s tiny IXPE X-ray space telescope.

Falcon 9 booster B1067 arrived at Port Canaveral not long after but spent most of the winter holiday sitting on drone ship A Shortfall of Gravitas (ASOG) as many SpaceX employees took a well-deserved break. The thrice-flown booster was ultimately lifted onto the dock and broken over a few days before B1069 finally sailed into port, setting it up for a fourth launch in the very near future.

Ultimately, while the damage B1069 and JRTI’s Octagrabber seemingly suffered are a significant annoyance and will take a good deal of time and money to fix, SpaceX still has ten other operational Falcon 9 boosters ready to support a potentially record-breaking 2022 launch manifest.

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.
