While for the Anu, with their long lifespan, it was normal to send out a ship with a mission of a few hundred thousand years, this mission was a very important one to all of them: a race evolving into sentience is a rare occurrence, and the data from this study were much anticipated. Of course the crew was carefully selected.
Among the 200-300 crew were a large variety of scientists from different disciplines, and a small group of military, to operate the ship and handle any unexpected problems along the way.
The stories of the crew are still told among humans today. Ancient mythologies tell us about Enki, the leader of the scientists, and Enlil, the leader of the military, but also about Inanna and Ninhursag.
