No, but you can't until someone pays to develop the technology.

Right... how does space advertising relate to that though? Are you saying that's the only viable business model for space travel and colonization?

No. but it's one. And, since we don't quite know which one will pay the bill, we need each and every model we can get.

How did you "check the orbits for your evening"? just curious, i would like to check my own from time to time and have a look on a clear night. If it is something a layman can do?

http://heavens-above.com First you’ll need to set your location, then click on “daily predictions for brighter satellites”. For your first time watching, look for ones brighter that 3.0 (maginitudes get brighter as the number gets smaller. So a 6.0 isn’t one most people can see with their eyes, 2.0 is a bright, easy to see star and a zero is one of the brightest stars in the sky). Also make sure the satellite is goin…

this is awesome, thanks

Those served an actual purpose though. They weren't just shoved into space just to say, "hey look at what we did". That's the point they're making. Don't pollute space just because you can. EDIT: typos

One could argue: this one gets press, which gets funding, which is quite important for science.

that's a good point

This is utterly, utterly overblown. The Space Station is thousands of times bigger and throws back a hundred times more light than this will. Every evening, for most of the populated world, dozens of brighter satellites than this go overhead. I just checked the orbits for my evening here - 57 brighter satellites. But what about the flashing? Well, we've got those already too. The old, awesome Iridium satellites have…

> It is expected to become the brightest object in the night sky for nine months until it re-enters Earth’s atmosphere. That sounds like a pretty big deal to me.

There’s no way it’s true though. It’s simply not big enough.

This is the site I normally use: http://heavens-above.com/main.aspx

There's lots of similar websites and apps now if you search around.

There is a metric ton of regulation you can’t launch anything into space without going thorough a mile of red tape. Apparently no one consulted astronomers with this case most likely as no one expected a use case where someone launches a freaking disco ball into low earth orbit.

That's sort of my point though. Every edge case that gets exposed gets another regulation.

Well Elon Musk is about to launch a Tesla into Martian orbit perhaps its time to put orbits other than sol orbits under the regulatory red tape.
