SpaceX’s Crew Dragon settles on Feb 9 launch debut as Falcon 9 nears static fire

Update: NASASpaceflight.com is reporting that ISS planning documents suggest that Crew Dragon’s first launch has slipped into the second half of February, perhaps February 16th. 

In the midst of several confusing delays, schedule updates, and official statements, the orbital debut of SpaceX’s Crew Dragon spacecraft has made its way onto the Eastern range’s planning schedule for the first time, placing Falcon 9 B1051’s static fire and Crew Dragons launch no earlier than (NET) January 23rd and February 9th, respectively.

As the brand new spacecraft’s first attempted trip to orbit, the demonstration mission (Demo-1/DM-1) will be performed without crew aboard, allowing SpaceX and NASA an opportunity to fully verify performance and explore Crew Dragon’s capabilities without risking the lives of the astronauts that will step inside a nearly identical vehicle as early as June or July.

The US government has been shut down for more than four weeks as a consequence of the inability of elected representatives to pass and sign a funding bill, now the longest shutdown in the country’s history. As a result, more than 95% of NASA’s workforce has been furloughed, leaving around 800 people left working (without pay) across the agency in positions or groups deemed absolutely essential to avoid loss of life or property damage.

How NASA defines “essential” is unknown but it seemed improbable that the Commercial Crew Program –  around six months away from actually launching astronauts and presently marked by NASA’s attempts to complete reams of approval and certification paperwork – would fall under that extremely narrow umbrella. Delays to Crew launches are unlikely to harm hardware or directly risk harm to astronauts, although a very tenuous case could be made that delays to the program now would snowball and cause the debut of operational crewed launches to slip so far into 2019 (or even 2020) that NASA could lose assured access to the International Space Station (ISS) for several months. Again, there is no obvious way that a slip like that would actually increase the risk to life or limb for astronauts and hardware/infrastructure.

Despite the logical improbability that NASA’s Commercial Crew Program (CCP) would – at this point in time – remain operating at full capacity during an extended government shutdown, NASA provided a statement to The Atlantic earlier this week more or less implying that CCP was deemed essential and has continued to operate for the last several weeks. There is certainly some wiggle room in NASA spokesman Bob Jacobs’ comments, enough to make it ambiguous if they are primarily PR spin, frank honesty, or something in between.

A SpaceX spokesperson added [paraphrased by The Atlantic] that “if NASA made the call, the company would carry out the uncrewed [DM-1] launch”, a tactical nonanswer that redirects the impetus to NASA. It’s not clear if the people at NASA that would ‘make the call’ to launch are furloughed or not – they certainly would not be essential in the sense described by NASA’s own overview of the current shutdown’s impact. Originally targeting a launch sometime in mid to late January, an official NASA update posted on January 10th showed that Crew Dragon’s first launch had slipped into February (on the launch range for February 9th).

 

“NASA and SpaceX are now targeting no earlier than February for the launch of Demo-1 to complete hardware testing and joint reviews.” – NASA, 01/10/2019

“Hardware testing” likely refers to the need for Falcon 9 to complete a static fire at Pad 39A, a test now scheduled for January 23rd. It’s ambiguous whether SpaceX can actually perform a static fire test – a complete launch rehearsal involving full propellant loads and the ignition of all nine Merlin 1D engines – at Kennedy Space Center, a NASA operated with federal funding that does not currently exist. Although the Air Force-helmed range is operating at a normal capacity, KSC must still perform a number of basic tasks ranging from infrastructure maintenance to roadblock setup to allow a static fire test – let alone a launch – to occur. I

f SpaceX completes its NET January 23rd static fire with no problems, then it would appear to be the case that some sort of SpaceX-side delay – perhaps augmented or slowed down by NASA operating at 5% capacity – caused the slip from mid-January to mid-February. Stay tuned to find out!

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.
