    An emotional example. I'm sure there are other ways to serve such communities.

    42,000 satellites (if the ITU approves) with a life span of five to seven years. Six to eight thousand satellites launched each year just to keep up with the constellation. All designed to burn up upon reentry. Less than a couple thousand in orbit and already causing problems for astronomers and those who enjoy the night sky. We have several "dark sky communities" in my area who have taken special efforts not to pollute the sky with light so stargazers can see the stars. Can we get Elon to stop polluting the sky?

    Oh well, maybe we will be able to stream 8K recorded video of the sky via Starlink when Starlink blocks out the sky.

    How many such organizations do you suppose Starlink enlisted into their beta test?

    Would the bandwidth that Starlink offers come anywhere near serving their needs?

    I don't know the all number of units involved, but the tribes and school districts served so far seem to be quite pleased according to their public statements. I recall a rural VA school district mentioned getting 45 user terminals for un-served families with students, and a rural Texas school district where 39% of the students had limited or no Internet access was getting 90 terminals for under-served families. Starlink has also equipped pilot programs in NC and OH, and possibly others that I don't recall. Then there's the Hoh tribe in WA that Starlink has brought high speed Internet to, and the Pikangikum First Nation in north-western Ontario. There's probably others, but that's what comes to mind...

    You obviously have no idea how much room there is up there. The orbital plane of the satellites is larger than the earth's surface. If you had a few hundred satellites sitting/floating on the earth's surface and threw rocks randomly at the earth, how many rocks do you think you'd have to throw before you hit a satellite?

    Orbital sphere? Radius of Earth 3958.8 miles. Altitude of Starlink satellites 180 miles at launch, 341 miles in operation.
    Area of Earth surface 197 million square miles (roughly). Area of Starlink orbital sphere 232 million square miles. Not much difference.
    Starlink will not be covering their entire sphere, only the portion between 60 degrees south and 60 degrees north.
    So, 42k planned satellites in a 154 million square mile area constantly moving. One satellite every 3,682 square miles?
    This defines the "rock" ... 42 thousand rocks in constant motion 60 miles apart blanketing the Earth.

    Hello.
    Interesting discussion.
    1 - A few hundred? There are over twenty thousand catalogued items in the unclassified database larger than a softball orbiting the Earth as we speak:
    Space Debris and Human Spacecraft

    2 - I find some of the opinions presented... interesting. On one hand, it is like being angry about an interstate being plowed through someone's fields and yards. On the other hand, I am old enough to remember walking on beaches with zero glow from cell phones, video cameras, tablets and other distractive devices. Or a concert where I didn't have to peer between hundreds of upstretched hands clutching large cameraphones, all trying to catch the same 'special moment'.

    I don't know what the right answer is; as a former Boy Scout, I spent my fair share in the 70's and 80's peering up at space from mountaintops unobscured by light pollution. I appreciate the beauty. But I also don't have an issue with cell towers, because I appreciate the convenience. Perhaps there is a middle ground, but I've found it always skews towards money, not beauty or common sense.

    looks like it's going out of beta testing next month. and should be fully mobile also with the launch of some more birds and software updates.. perfect for rvr's. i also heard this system will hit gig speeds. that has yet to be seen so maybe with more birds in the sky and software updates it will happen...
