George's Cosmic Treasure Hunt

''We are going,'' said Annie, ''on a great cosmic journey. So listen up, Savers of Planet Earth, and prepare to meet the Universe.'' George''s best friend Annie needs help. Her scientist father, Eric, is working on a space project - and it''s all going wrong. A robot has landed on Mars, but is behaving very oddly. And now Annie has discovered something wierd on her dad''s super-computer. Is it a message from an alien? Could there be life out there? How do you find a planet in outer space? And if you could talk to aliens, what would you say?
