Less than a month after the complete loss of customer payload due to an in-flight anomaly, Rocket Lab has announced that it is ready to return its small-class Electron rocket to flight. Company CEO, Peter Beck, during a media briefing Friday (July 31) said that the Electron second-stage “re-entered the atmosphere and burned up” resulting in a failed July 4 launch of the Electron and complete loss the customer payload of seven small satellites. Beck went on to state that through a collaborative investigation with the Federal Aviation Administration Rocket Lab was “able to quickly reconstruct what happened and the AIB board (Accident Investigation Board) was able to confidently narrow down the issue to a single electrical connection.”

The thirteenth flight of the Electron carried seven small satellites, all Earth-imaging inspiring the “Pics Or It Didn’t Happen” mission name. The rocket initially experienced a flawless launch from the company’s Launch Complex-1A on New Zealand’s Mahia Penninsula and everything seemed like it was going to plan until the video feed cut out unexpectedly shortly after the nominal ignition of the second-stage which was intended to carry the payloads to orbit.

The launch was completely event free during the first-stage ascent, stage separation, second stage ignition, and payload fairing jettison, then trouble occurred. Beck stated that the electrical connection that went bad during the second-stage of the flight was “incredibly unusual because it was able to evade all of the pre-flight acceptance testing.” Beck went on to explain that “while all of the testing showed no issues, after a period of time one of the joints had high resistance and that high resistance led to heating. That heating then led to thermal expansion of one of the components. That thermal expansion and heating enabled some of the potting components – that are around that joint to keep it secure from vibration – to flow.”

Once the potting compound used to secure electrical connections was able to heat up and essentially melt – or began to flow – the electrical connection become unsecured and led to the interruption in electrical current throughout the second-stage. Beck stated that “when the video stops (in the webcast) is exactly the point (of failure).” Although the video cut out, Rocket Lab ground stations continued to receive telemetry data of the flight’s progress due to the amount of redundancy with the systems aboard Electron “telemetry is the only way you can reconstruct this stuff so we have a very high priority of those (data) channels” Beck said.

With the immense amount of data that was received during the flight and throughout the second-stage shutdown Rocket Lab was able to quickly determine the cause of the error and perform tests to determine exactly what occurred during the failed flight. “The vehicle as it flies every flight has just a huge amount of instrumentation. That coupled with a graceful shutdown coupled with full telemetry stream throughout the whole anomaly, we were really able to quickly reconstruct what happened” Beck said.

The vast amount of data and the ability to sufficiently replicate the incident now means that Rocket Lab has a plan of action in place to mitigate any failures – of this nature – on future missions. “We can actually mitigate (the anomaly) very easily through a slight change in production processes, but more importantly we can screen for it in our current vehicles and stock through more in-depth testing procedures.”

To that end, the Rocket Lab Electron is set to return to flight in August, an impeccable turn around time following an anomaly investigation.”I’m very proud of the way the team has been able to identify this issue and rectify it so quickly” Beck said. He gave high praise to the entire Rocket Lab team for relentlessly working toward determining, not only the cause of the anomaly but working toward a solution for a quick return to flight. “Literally ten minutes after we saw some anomalous behavior during the flight, the team already started to work it and they haven’t stopped. They’ve been relentless” Beck said.

The customer payload that will fly aboard the return to flight and fourteenth mission of Electron launch is expected to be announced very soon. Rocket Lab did state that following a successful launch from the LC-1A complex in New Zealand, the following mission would be the first to take place from the brand new Launch Complex 2 located at the Mid-Atlantic Regional Spaceport at NASA Wallops in Virginia. Although an American private company, Rocket Lab predominately launches from New Zealand. The upcoming mission will be the first Electron flight to occur from American soil.

Beck closed the media briefing by stating that Rocket Lab looks forward to returning to operational status and launching Electrons every month, if not bi-weekly. He expressed that Rocket Lab is looking to the future and hopes to achieve a full recovery effort of the first stage booster via a helicopter and a specially designed grappling hook with the seventeenth flight of Electron. He also hinted that “there’ll be a couple of other little surprises as well, as we execute some other programs that have been cooking up in the background.”

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.
