Looting Asteroids' Water Will Make Launches Cheaper

There are hundreds of satellites in geostationary orbit, meaning that they orbit the Earth at roughly the same pace that our planet spins. So how do you get one of these satellites up to this extreme altitude? The traditional methods include strapping on an extra rocket or rocket stage to kick them into high orbit, or using a lightweight electric thruster on the spacecraft that slowly pushes the satellite to the right spot.
