I have no idea if it's actually relevant re the space rocks traveling with the ship, but I do remember reading the book Lost Moon [later retitled Apollo 13 and the basis for the movie]. There was a lot of debris that was sort of sucked along with the ship making it difficult for them to see the 'real' stars necessary for course corrections, etc. because of the sunlight bouncing off all that debris making 'fake' stars. They had to wait until they were on the dark side to see real stars. That was my thinking - that they were dragged along like that debris was...
