[Prometheus] Why does Dr. Elizabeth Shaw choose to go immediately to the Engineer home planet instead of Earth at the end of the movie?

How is she going to get supplies to survive the trip given that a commandeered Engineer spaceship likely wouldn't have food, water, or toothpaste available? Why not stop at Earth to resupply? Showing up on Earth with an alien spaceship is bound to get some attention and possibly get support for a well supplied and staffed mission to the Engineer home planet.

If she brought the ship back to earth, Weylund-Yutani would have taken the ship for reverse engineering and Dr. Shaw would have been disappeared. There was no way the Corporation was going to let all that profitable technology go to pick a fight that could destroy or damage their bottom line.
