Pardon my ignorance, but how in the hell do we get other things into space with all of this in way?

Wow. I allowed Chrome to know my location for the first time and Street View was in my front door. I thought it was going to use the IP but it's impossible to be that accurate, does it Chrome use my Home on my profile location or something like that?
The Street View cars log information about wifi access points, and use wifi data from your device to guess your location.
That'd explain the changes to Location Services on Android over the past several years.

#103I wonder how much light is blocked by this stuff floating around? Seems like there are parallel efforts to make atmospheric dust while this is already up there.

#104If you enter "1" for the visualization speed, is that the actual recorded velocities?

Is it related to Android though? I read somewhere/thought that it is primarily the Google Maps cars recording WiFi data and not phones). Europe wouldn't be covered at all if it was coming from the phones, right? (GDPR)
I mean, you can have a street full of iPhones - which I assume is a regular occurrence in USA, where people trust Apple - and still Google Maps on iPhone would guess well enough where you are. For example, I'm far away from the street and Google hasn't passed here recently, so my WiFi-based location is always way off (using Android). In my other home (and vacation home in another country) it's the opposite, because the cars have passed quite recently.
The story checks out so far for me... but I am kinda lazy to search for the source on this right now, so pls share if you have it.

Looks familiar...(!) https://youtu.be/fEkXTV69yo4?t=22s
>> https://youtu.be/fEkXTV69yo4?t=22s Holy S$#! I didn't know about that. Are there links between this Space Force project and Starlink?
It just shows what an orbiting satellite constellation looks like and why so many are required. That is the similarity

I believe this data mainly comes from phones, not street view cars. There are about a million times more phones out there than street view cars, and they all have GPS and Wifi. Apple had this feature long before Apple Maps was a thing, and they didn't license Street View data from Google.

Thank you for this. While the visualization is useful/interesting, it frustrates me how often similar visuals are used in news stories about space junk. Yes, it's a problem, but using visuals like this without proper explanation misrepresents it terribly.
Yes, and they don't add footnotes. From visualization it looks like crash is inevitable. But yeah, otherwise there would be no visualization. Think about it: they say 19334 objects are tracked. Imagine that many cars or trucks in the world scattered all across. Then extrude that to couple hundreds of kilometers. Would that feel congested to you? 19334 new cars are being manufactured in less than 2,5 hours...
And that's before you add oceans and horizontal planes...

> but there's only a handful of these. Huge if true.
Oh, there are plenty of US satellites with classified payloads/missions; I just mean that most classified US satellites DO have orbital elements listed in the Space Force catalog.
I'd add that it would be pointless to try to hide a fair number of them, given that they approach the size of school buses (no joke — the now-retired KH-9 was nicknamed "Big Bird" for good reason) and can be imaged on relatively consumer-ready optics. Some Russians made a nice stink a few years ago by using (IIRC) laser illumination to make some relatively high-res shots of American recce sats.
The interesting aspects of them have to do with how far off-axis they can function. This was the major consequence of loss of the Morison leak of the KH-11 shots of a Soviet carrier to Jane's Defense Weekly — the image revealed how far off-axis it could image and some clues to how it processed imagery.
