Whats the satalie called in space?

Question

what is the telescope called that is in space and can zoom in so much it can read writing on an A5 piece of paper

Answer 1

You may be telling about Hubble space telescope????

But reading A4paper from space is not possible!

Answer 2

No space telescope (Hubble or the various similar spy sats) using visible light can read writing on a A5 piece of paper. The wavelength of the light makes this kind of magnification impossible.

Hubble could see the light of a candle in many million km distance - but it couldn't help you see the candle itself.

Answer 3

The Hubble Space Telescope might be the "telescope in space" that you're thinking of, but it cannot zoom in and read writing on a piece of paper on Earth.  It cannot even take a picture of the Earth's surface.  

*The surface of the Earth is whizzing by as Hubble orbits, and the pointing system, designed to track the distant stars, cannot track an object on the Earth. The shortest exposure time on any of the Hubble instruments is 0.1 seconds, and in this time Hubble moves about 700 meters, or almost half a mile. So a picture Hubble took of Earth would be all streaks.  

As for Hubble's optics; +When astronomers talk about how clearly a telescope "sees," they are referring to its resolving power, or resolution — how fine a detail it can see or how close together two objects (such as stars) can be and still be seen as two distinct objects. Astronomers measure the resolving power of a telescope in terms of degrees. Degrees are further divided into arcminutes and arcseconds.

1 degree = 60 arcminutes = 3600 arcseconds

The best telescopes on the ground can rarely see detail that is less than 1 arcsecond wide or differentiate between two stars that are less than 1 arcsecond apart in the sky. This is because turbulence in Earth's atmosphere causes images to ripple and shimmer. By comparison, Hubble can see detail down to less than 0.1 arcsecond across — more than 10 times clearer. This is one of the main reasons astronomers like to use Hubble.
