Text in Arabic. Eleven-year-old Alex Petroski loves space and rockets, his mom, his brother, and his dog Carl Sagannamed for his hero, the real-life astronomer.

All he wants is to launch his golden iPod into space the way Carl Sagan (the man, not the dog) launched his Golden Record on the Voyager spacecraft in 1977.

From Colorado to New Mexico, Las Vegas to L.A., Alex records a journey on his iPod to show other lifeforms what life on earth, his earth, is like.

But his destination keeps changing. And the funny, lost, remarkable people he meets along the way can only partially prepare him for the secrets he'll uncoverfrom the truth about his long-dead dad to the fact that, for a kid with a troubled mum and a mostly not-around brother, he has way more family than he ever knew.
