Are there any sites that have live satellite feeds of the earth?

Google Earth doens't, just old snapshots. Im talking live views of street level activity, is this even possible? Would be so fascinating.|||Closeup pictures live all the time is impossible. Weather satellites are almost live, but they don't show small detail.





To get detail good enough to show cars requires a big lens or telescope pointing at the ground from a LOW orbit. Like 200 or 300 miles up. The low orbit means 2 things. 1, you can't hover over one spot; you are always moving rapidly over the ground. You only pass over a given spot once every few days. 2, from that close you can only see a small area at a time, maybe a hundred miles wide or whatever.





Weather satellites are in geostationary orbit, 22,000 miles up. They can hover in one place forever and see continents and large scale cloud patterns, but not small things like buildings or cars.|||NASA.com is the closest you'll get.
