SpaceX’s first “next-gen” Starlink satellites are suspiciously familiar

Published

on

In a strange twist, SpaceX says that its next Starlink mission will launch 54 satellites into low Earth orbit (LEO), implying that they’re roughly the same size as the V1.5 satellites it’s already launching – not the larger V2 or V2 Mini satellites discussed in recent FCC filings.

However, the data SpaceX provided also shows that those 54 satellites are headed to an orbit that only matches the company’s next-generation Starlink Gen2 (V2) constellation. While SpaceX quietly indicated that a V1.5-sized satellite was an option for early Gen2 launches in a supplemental October 2022 filing [PDF] with the FCC, it’s still unclear why SpaceX would prioritize launching V1.5-sized V2 satellites while its V1 constellation remains unfinished.

Adding to the confusion, in November 2021, CEO Elon Musk strongly implied that the inefficiencies of smaller Starlink V1.x satellites were so significant that they could risk bankrupting SpaceX if the company couldn’t start launching larger V2 satellites on its next-generation Starship rocket by the end of 2022. What, then, is the purpose of SpaceX’s imminent “Starlink G5-1” launch?

The name alone is confusing. Using the same shorthand as past Starlink V1 launches, “G5-1” refers to the first launch of “Group 5” of a constellation. “Group” here is synonymous with “shell,” which describes a set of satellites that share the same orbital inclination (the angle at which the orbit crosses the equator) and a similar orbital altitude. Of SpaceX’s three approved constellations, only one has five shells, and that shell can only exist at 97.6 degrees, not 43 degrees. SpaceX’s Gen2 constellation technically has nine planned shells, but the FCC has only partially approved three of those shells, one of which is at 43 degrees.

Ignoring the obtuse name, one possibility is that aspects of Starlink V2 satellite upgrades are not explicitly tied to the much larger size of those satellites and can be applied to SpaceX’s first-generation Starlink constellation without requiring a modified FCC license. If SpaceX wanted to add larger satellites to its V1 constellation or change the frequency bands they use, it would almost certainly have to seek a modified license from the FCC, which could take months.

There is no evidence SpaceX has done so, and any attempt would produce public documentation. The 43-degree inclination SpaceX’s mysterious “Starlink G5-1” launch is targeting also rules out any involvement in its V1 constellation, which only has approval for satellites between 53 and 97.6 degrees.

Aside from the unlikely possibility that details about the Starlink 5-1 mission are somehow incorrect or an artifact of a messy launch licensing process, there is at least one other unlikely explanation. In October 2018, the FCC granted SpaceX permission to launch a very low earth orbit (VLEO) constellation of 7518 Starlink satellites with dimensions similar to satellites that make up the 4408-satellite constellation the company is currently launching. More than four years later, SpaceX has yet to begin launching its approved VLEO constellation.

In November 2022, SpaceX told the FCC it intended to combine its Starlink VLEO and Starlink Gen2 constellations by adding V-band antennas to some of the almost 33,000 Gen2 satellites it hoped to launch – a move that would reduce the total number of Starlink satellites SpaceX needs to launch. Around the turn of the month, the FCC partially granted SpaceX’s Starlink Gen2 license, adding unprecedentedly strict requirements and only permitting the launch of 7500 of 33,000 planned Gen2 satellites to a limited set of inclinations (33, 43, and 53 degrees).

Perhaps, then, the uncertainty created by the FCC’s strange partial Gen2 grant made SpaceX change its mind about a dedicated Starlink VLEO constellation. However, without a license modification, SpaceX’s VLEO constellation is stuck with the same smaller (and potentially bankruptcy-inducing) satellites that its CEO believes make the first Starlink V1 constellation unsustainable. SpaceX also has less than two years until its VLEO constellation crosses its first deployment milestone, at which point the company will need to have launched half of it (3759 satellites) to avoid penalties from the FCC – up to and including the revocation of its license.

Despite the numerous reasons it wouldn’t make sense for Starlink 5-1 to be SpaceX’s first Starlink VLEO launch, almost 2500 of SpaceX’s approved VLEO satellites were intended to operate in a 336-kilometer (~209 mi) orbit inclined by 42 degrees – oddly similar to the 338-kilometer (~210 mi), 43-degree orbit SpaceX appears to be targeting with Starlink 5-1.

A surprise VLEO launch is a very unlikely explanation, but it’s only marginally stranger than the alternatives: that Starlink 5-1 is a V1-sized V2 launch with no prior mention or warning, a V1 launch to an orbit that would explicitly violate SpaceX’s Starlink V1 FCC license, or a paperwork error that has propagated so far that SpaceX distributed incorrect orbit information (which could threaten other satellites and rockets) less than two days before liftoff.

Thankfully, there is one last explanation – raised after this article was published – that appears to be much more likely. In response to a tweet summarizing these claims, astrophysicist Jonathan McDowell noted that SpaceX had, in fact, mentioned a third smaller Starlink V2 satellite variant in an October 2022 FCC filing that fell mostly under the radar. In that filing, SpaceX told that FCC it was developing three variants, not two. The smallest variant was said to weigh 303 kilograms and featured dimensions seemingly identical to SpaceX’s existing V1.5 satellites, which are estimated to weigh around 307 kilograms. SpaceX also stated that initial Falcon 9 launches will carry “approximately twenty to sixty satellites,” again confirming that V2 satellites could be about the same size and shape as V1.5 satellites.

SpaceX’s decision to develop a V1.5-sized version of V2 satellites makes little sense in the context of Musk’s implicit claims that problems inherent to its smaller V1 satellites threaten the company’s solvency. It’s clearer than ever that the SpaceX CEO may have been stretching the truth of the matter to craft an existential threat that might encourage employees to work longer hours. Still, developing and launching a V1.5-sized V2 satellite variant and beginning to launch those satellites while SpaceX’s Starlink Gen1 is more than 25% incomplete is confusing at best.

Regardless of what it’s carrying or why, a SpaceX Falcon 9 rocket is scheduled to launch Starlink 5-1 out of Florida’s Cape Canaveral Space Force Station (CCSFS) no earlier than 4:40 am EST (09:40 UTC) on Wednesday, December 28th.

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.
