SpaceX’s first launch of Crew Dragon with astronauts on board may have to wait a few more days to get off the ground, but that doesn’t mean that the company isn’t already looking forward to the future. Following Demo-2, and if all goes as planned, NASA is expected to certify the Crew Dragon spacecraft for regular flights to and from the space station.

At that time, SpaceX and NASA will start nailing down the details for its next crewed mission. Each Dragon spacecraft is certified to stay on orbit for no more than 120 days, so they have to time everything carefully. That’s why the length of Demo-2 is uncertain — it all depends on when the next spacecraft will be ready.

That could happen sooner rather than later. NASA administrator, Jim Bridenstine, explained during a pre-launch briefing that the next flight of the Crew Dragon could fly as soon as August 30. That flight, called Crew-1, would see the Dragon carry four astronauts to the space station for a six-month stay. On board will be three NASA astronauts Mike Hopkins, Victor Glover, and Shannon Walker — who will be joined by Japanese astronaut Soichi Noguchi.

However, before they can fly, the Demo-2 crew of Doug Hurley and Bob Behnken are putting the Dragon through its paces. It’s their job to test out the craft’s various systems on this final test flight. Crew Dragon has already made one successful flight to the space station, but that was without a crew on board. When it flies this next time, Bob and Doug will not only test out manual controls of the Dragon’s flight systems, but also the craft’s ECLISS (or environmental control and life support system).

Bridenstine stresses that Demo-2 is a test flight. The mission is designed to test the vehicle, land it safely, and prepare to regularly launch crew. To that end, there will be several weeks in between the Demo-2 flight and the launch of Crew-1. This will allow SpaceX and NASA to inspect and certify the Dragon.

“They can be there probably until early August,” Bridenstine said, referring to the Demo-2 mission. “If we have a good window to come home and they are not necessary on the International Space Station, we will be taking it.”

“The goal is to get them to the International Space Station, test the systems and get them home,” he added. “If they can do more work than that while on the ISS, certainly that’s OK. But this is a test flight.”

Behnken and Hurley will be joining fellow NASA astronaut Chris Cassidy on station. Cassidy, along with two Russian cosmonauts, launched to the station in April. They’ve been serving as a skeleton crew, so the addition of two more astronauts will be welcomed.

SpaceX snagged a $2.6 billion contract in 2014, to fly six operational crewed missions for NASA. For nearly a decade now, NASA has been forced to rely on Russia as the sole means of transporting astronauts to and from the orbital outpost. This arrangement is expensive, with seats now costing NASA approximately $90 million each.

Once Crew Dragon is fully operational, NASA hopes to end its payments to Russia. It would lie to establish a barter system for seats instead. NASA is hopeful that the Russians will want to fly on the Dragon and are wanting to trade seats with the Russians in the near future.

That arrangement would see U.S. astronauts continue to fly on Soyuz spacecrafts as well as Russian cosmonauts fly on U.S. spacecraft with no money being exchanged. Russian officials have said they would be open to putting cosmonauts on U.S. vehicles after they’ve been fully certified.

Russia as well as many international partners participated in the Dragon’s readiness review process along with NASA. The Dragon passed both its flight readiness review and launch readiness reviews with flying colors. Right now, the only thing standing in its way is launch weather.

Currently, NASA and SpaceX are targeting Saturday, May 30 at 3:22 p.m. for liftoff.

Tesla silences Robotaxi turn signals in sweeping but polarizing change

Published

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.

Elon Musk

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.”
