How much data is contained in Google Earth?

Q. How much space does the entire collection of Google Earth satellite images take up? and Google Street View?

A. These kind of sites are not web based but the server based so they can increase the spase as well.........

How do I update google earth satellite pictures?
Q. Ok. I am on my itouch 4g 64GB.Then u am on google earth. Then I have the satilite of my house in 2009 and it is 2011 how do I update it?

A. You can't the Google Earth pics are maintained by certain governmental agencies and are scoured when taken to blur out peoples faces or other unwanted images, flying airplanes, ufos . then they are uploaded so that google can access them..New pictures have probably been taken but it takes a while for them to be posted due to this "cleaning process" this is why you never see a plane in flight in flight on google earth. and why it takes a long time to update the pictures used for google earth.

Could people ever look at an extrasolar planet's surface like the program Google earth does?
Q. I know Google earth is a collection of satellite photos, but what I'm really asking is; Is it possible to create such a powerful direct imaging telescope? Could a great enough resolution be attained, viewing from our solar system, to see the surface clearly, clear enough, to see alien forests and whatnot. I know it wouldn't happen any time soon, but is it theoretically possible?

A. In theory it is possible to obtain any degree of magnification, but it won't work in practical application because we can not built on this precision level, plus it would have to be like the Hubble space telescope because on that degree the particles in the atmosphere would distort the image. We can create detailed images by sending satellites to other planets, this is what we currently do. Next time you are on Google earth try out it's moon and Mars models. It has the surfaces of these planets in 3-D with nice pictures, just like the earth. You can even "visit" the landing sites on these planets from our missions and see what the surface looks like from any point on the planet.
