Weather satellites above Earth stay in perfect, geosynchronized orbit, so you can probably guess at which one is keeping an eye out for events like Sandy. New Yorkers? Probably GOES-13. Calfornians? Good ol' GOES-15.
The satellites are 22,300 miles up, which puts them higher than most satellites, but that number's key: any higher or lower and they'd move faster or slower than the Earth spins, putting them out of their carefully crafted orbit.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
