Try this . . . drag the frame around and around in a circle until you can see the Continental US. Notice the fat cluster of satellites parked over the US in the outer ring? Click on one of them. Select the option 'Center on satellite,' and then speed the simulation up to the maximum possible speed and refresh rate.
You can see most of the satellites in this cluster hover right over the US while all the others are zipping all around. I think you can also get that orbit info from the drop-down menu, but it's cool (I think) to see it in action.
I haven't checked 'em all out yet. I wish they'd give us a little more information, such as whose satellite it is and what it's doing. I'd like to know how many of them are Russian.
BTW, I found that site through this under-appreciated post. I still haven't been able to explore all of it.
I definitely get the feeling that someday we're going to be able to click on a satellite on some webpage like this one in the future, and check out all the images and all the data it's collecting on the Earth (that is, as long as the satellite isn't a military one). I sure hope it's reasonably priced. Right now, I think their prices are a bit steep for the little guy.
At the risk of being totally obnoxiously officious (and a million apologies if I am being), zoom in until the earth completely fills up your monitor. Then the cloud resolves itself into hundreds of little specks. Set the refresh rate to 1/4 second and watch the satellites as they approach your hometown.
I'm gonna try to use it tonight to see if I can pick 'em up in binoculars as they fly over. A lot more fun than looking up the transit times for observable satellites in some table.
They even track rocket boosters (the name will end in R/B). :-)
