It's because satellites have a circular orbit. They aren't directly above every single point on the planet. If a satellite wants to take a downwards pciture of an area that it doesn't pass directly over in its orbital path, it has to orient itself to point towards it.
no.
satilites like this are in polar leo orbits.
Reson? There closer to the earth.
And they pass over every single point on the earths surface twice a day.
Without needing any correction. (some i've seen are just passive mag stabalising. Most have solar spin stabilisation as well tho. These are for the microsats. Like echo. The bigger ones usually use momentum wheels, active mag as well as monopropellant thrusters. (hydrazine or h2o2 iirc. W/ a paladnium or silver catalist i think.) These can point themselves where they need.)
Its also cheaper then geo's. (Its a lower orbit).

Nice coder

Damn, I wish Google Satellite worked for Australia so I could join in
me too [sad]
It still orbits around the earth in circles, it's just that the earth turns underneath it, giving it an effective 2 axes of movement. It still doesn't pass directly over every point on earth though. It makes bands across the earth, within which it still has to rotate in order to take snaps of points on the outer edge of its range, or indeed anything that's off dead center.
I'm at college now (University of Nevada, Reno), here's my dorm in red. Every building in this picture is the college.
i remember finding my house on terraserver some years ago, they had awesome coverage of europe ...
bummer its not free anymore :-(
