Star system project backed by Stephen Hawking

A project to send tiny spacecraft to another star system within a generation has been backed by Professor Stephen Hawking.

The concept is to reduce the size of the spacecraft to about the size of a chip used in electronic devices and propel them from earth using solar sails and a giant laser.
