They don't go backwards in time. They go forward in time slower than someone that stays on Earth.
Special Relativity deals with time dilation as it is caused by speed. Travel faster, time goes slower.
General Relativity deals with time dilation as it is caused by the warping of space-time. Time ticks slower near more massive objects.

Sorry, yes, that is exactly what I meant.....I didn't mean astronauts go back in time, but rather that because they are traveling at fast speeds, time slows for them.
General relativity sounds very interesting.....maybe I'll delve into a few good books about.
