Speaking at Tesla’s annual shareholder meeting, CEO Elon Musk – also CEO of SpaceX – briefly segued to his spaceflight company’s ambitious Starlink program and discussed how he believes the satellite constellation can support no more than 3-5% of the global population.

On May 23rd, SpaceX successfully launched 60 “v0.9” Starlink satellites – weighing as much as 18.5 tons (~41,000 lb) – into LEO, a first step unmatched in ambition in the history of commercial satellites. Delivered to an orbit of ~450 km (280 mi), all but four of the 60 spacecraft have managed to successfully power up their electric ion thrusters and 55 have already raised their orbits to ~500 km (310 mi). For what is effectively a technology/partial-prototype demonstration mission, the record of Starlink v0.9 performance is extremely impressive and bodes well for a quick and relatively easy design optimization (to “v1.0”) before true mass production can begin.

In general, Musk was more than willing to acknowledge some of the potential limitations of a Low Earth Orbit (LEO) broadband satellite constellation at Tesla’s 2019 shareholder meeting. Most notably, he bluntly noted that Starlink is not designed to service densely populated areas and will predominately be focused on low to medium-density populaces. Triggered by an investor’s question about the possibility of integrating Starlink into future Tesla cars, Musk reiterated that SpaceX’s first-generation Starlink user terminals (i.e. ground antennas) will be roughly the size of a “medium pizza”.

Although pizza sizing is not exactly ISO-certified, Starlink’s user antennas will presumably be around 12-14 inches (30-36 cm) wide and come in a square form factor. Thanks to the use of what Musk believes are the most advanced phased array antennas in the world, neither the antennas on Starlink satellites or user terminals will need to physically move to maintain a strong signal. Still, as Musk notes, an antenna the size of medium pizza box would still stick out like a sore thumb on the typically all-glass roof of an of Tesla’s consumer cars, although built-in Starlink antennas might actually make sense on Tesla Semis.

Elon Musk’s specific comment indicated that Starlink – at least in its current iteration – was never meant to serve more than “3-5%” of Earth (population: ~7.8 billion), with most or all of its users nominally located in areas with low to medium population densities. This generally confirms technical suspicions that Starlink (and other constellations like OneWeb and Telesat) is not really capable of providing internet to everyone per se.

For SpaceX, each Starlink satellite – per official statements that the first 60 satellites represent more than 1 terabit of bandwidth – likely offers bandwidth of roughly 17-20 gigabits per second. In simpler terms, this means that one Starlink satellite overhead could theoretically support as many as 4000 users simultaneously streaming YouTube videos at 1080p/30fps, a figure that sounds impressive but glosses over the sheer number of people that live in cities. Importantly, every single Starlink satellite at ~550 km will likely have a service radius of several thousand – if not tens of thousands of – square kilometers.

Although each satellite is just a few square meters, they may be able to serve internet to thousands of people simultaneously. (SpaceX)

Even though the US is exceptionally large and spread out relative to most other countries, a single square kilometer of New York City, Los Angeles, San Francisco, Boston, Miami, Seattle, or dozens of other cities could effortlessly saturate a Starlink satellite’s bandwidth. Even the smallest of towns and cities could easily use most or all of ~20 Gbps at peak hours. In short, Starlink is going to be extremely bandwidth-constrained. Even if SpaceX can double or triple each satellite’s bandwidth and have 10-100 satellites overhead and capable of delivering internet at any given moment, it’s hard to imagine that Starlink will ever be able to serve every person that falls under its coverage area.

Additionally, this means that there is a strong chance that Starlink internet customers will be subject to relatively strict bandwidth limitations and throttling at peak hours. Thankfully, these limitations will be made entirely out of technical necessity, standing in stark contrast to the arbitrary, greed-motivated carriers and ISPs Americans are almost universally accustomed to. In an absolute worst-case scenario, Starlink’s already-connected US customers would get roughly the same quality of service they are used to at roughly the same price. However, they would be able to rest assured that their money was going to SpaceX instead of filling the pockets of the robber-baron-esque shareholders and executives that run American ISPs.

Ultimately, the estimates provided above are exceptionally conservative and generally assume worst-case scenarios. SpaceX could very well beat expectations and develop unique and innovative ways of efficiently using its available bandwidth, while also tirelessly working to improve its technology and expand the carrying capacity of newer satellites. In general, CEO Elon Musk’s comments serve as an excellent temper to the hype surrounding Starlink. SpaceX isn’t going to initially be breaking the backs of Comcast or Time Warner but there’s no reason to believe that that day will never come.

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.
