Sagan had then explained: Theres just a tremendously exciting prospect called solar sailing.
The Solar Sail powered spacecraft is known asLight SailorSolar SailorPhoton Sailand it uses sunlight for propulsion.
Basically a Solar Sail powered spacecraft uses sunlight as its propellant and sun is its engine!!
So that means one can save a lot on the rocket fuel if Solar Sail powered spacecraft works successfully.
It is this reflection that exerts some pressure on the sail which can push the spacecraft.
Light Sail will be using 32 square meters of Mylar sail material.
Planetary Society is a non profit founded by late Carl Sagan and now it is headed by Bill Nyle.

Readers can give their opinion on this as well.
