The final weekend of August 2020 is shaping up to be an exciting one in the world of rocket launching. United Launch Alliance (ULA) looks to kick off weekend activities early on Saturday morning with the launch of its Delta IV Heavy rocket carrying a classified satellite payload for the National Reconnaissance Office at 2:04 am EDT (0604 UTC) from Cape Canaveral Air Force Station’s Space Launch Complex 37. Following a successful ULA launch, the weekend’s activity will kick into high gear. Even SpaceX founder and CEO, Elon Musk, agrees that this weekend could be “intense” as stated in a post to his Twitter account Friday, August 28.

According to weather Launch Mission Execution Forecasts provided by the 45th Weather Squadron and confirmed via the company’s Twitter account, SpaceX aims to get two Falcon 9’s launched from the Florida coast just nine hours apart. The company also has a possible flight test of its Starship prototype vehicle on the books from Boca Chica, Texas this weekend. Rocket Lab looks to join in the launching activity with the return to flight mission of its Electron rocket following the wrap-up of its recent in-flight anomaly investigation.

SpaceX can only launch this weekend if ULA does too

As SpaceX and ULA both launch from what is referred to as the eastern range – the location of all launches originating from Cape Canaveral Air Force Station or Kennedy Space Center – only one launch provider can be supported at a time by the 45th Space Wing and 45th Weather Squadron which oversee eastern range operations.

As a part of the reservation process ahead of securing a launch date with the eastern range, each launch provider chooses a targeted launch date and secures a number of back-up launch opportunities should a delay occur.

In the case of ULA’s NROL-44 mission, a primary launch opportunity and two back-up opportunities – 24 hours and 48 hours after the initial launch attempt – have been identified. This means that should the Delta IV Heavy suffer another critical issue resulting in a delay during its Saturday, August 29 primary launch attempt, both of SpaceX’s Falcon 9 launch opportunities will be delayed as well.

ULA’s NROL-44 Delta IV Heavy carries a classified satellite payload for the National Reconnaissance Office, a national security division of the United States government. As such, the NROL-44 mission is a matter of national security and takes precedence over both SpaceX’s internal Starlink mission and SAOCOM-1B payload for customer Comisión Nacional de Actividades Espaciales, Argentina’s national space agency.

If the ULA NROL-44 mission is delayed through both back-up launch opportunities SpaceX, presumably, would have to wait until no earlier than Tuesday, September 1 to launch a Falcon 9.

Rocket Lab “I Can’t Believe It’s Not Optical”

While SpaceX will have to wait for ULA’s Delta IV Heavy to clear its pad before attempting either of the planned Falcon 9 launches, Rocket Lab will attempt the return to flight mission of its Electron rocket – the fourteenth flight overall – regardless (weather permitting).

The launch attempt initially scheduled for 11:04pm ET (0304 UTC) Friday, August 28 was rescheduled due to high winds and heavy cloud cover over Launch Complex-1A in Mahia, New Zealand. The next available launch attempt at 11:05 pm ET Sunday, August 30 (0305 UTC Monday, August 31) lines up for Electron to take off just four hours after SpaceX’s SAOCOM-1B mission.

Following an in-flight anomaly during Electron’s thirteenth mission in July, Rocket Lab was forced to stand down from active launching status to complete a full investigation into the incident. In about a month’s time, Rocket Lab was able to track down and remedy an overheating issue with a single electrical connection on Electron’s second stage.

After receiving clearance from the Federal Aviation Administration to resume operational launches, Rocket Lab has announced that Electron’s fourteenth flight -nicknamed “I Can’t Believe It’s Not Optical” – will be a dedicated mission for Capella Space, a California-based company that utilizes Earth observation data to provide information services.

According to a statement provided by Rocket Lab, the satellite payload called “Sequoia” is “a single 100 kg class microsatellite which will be the first publicly available satellite in the company’s commercial Synthetic Aperture Radar (SAR) constellation.”

A big goal of Rocket Lab’s is to join competitor SpaceX in a class of launchers that regularly recovers and reuses orbital-class boosters. Rocket Lab intends to catch an Electron first-stage booster in-flight once it has been dispensed by catching the falling booster’s parachute canopy with a grappling hook secured to a helicopter.

However, the company has stated that a full-scale demonstration of this effort is targeted for no earlier than the seventeenth mission of Electron currently slated to occur in Fall 2020.

If all proceeds as planned, this weekend could end up as a launchfest of rockets and spaceship prototypes. At the time of publishing, all is proceeding as expected for ULA’s Delta IV Heavy launch attempt and the weather looks good on Saturday, August 29.

ULA has confirmed that the previous issues that caused a launch attempt delay have all been cleared and weather outlook remains at an 80% chance of favorable launching conditions.

The launch attempt will be streamed live and is expected to begin at 1:43 am EDT (0543 UTC) on the company’s website or viewed below.

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

Published

on

Credit: Tesla

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.
