What is the only thing Amy knows about Godspeed in the novel, Across the Universe?

From the text:

"They called it Project Ark Ship before I was frozen. All I know about it is that I'm on it. We're heading to a planet in the Centauri system that NASA discovered a few years before I was born. It's a generation ship - you are all supposed to have been born on the ship, keeping it running and all, until we get there and my parents and the rest of the people from the mission can terraform the new planet" (Chap. 17, p. 102).
