Very cool documentary movie on Netflix for subscribers called The Mars Generation, about the teenage generation of today that will likely make up the astronauts who make the journey to Mars. Features Bill Nye and Neil deGrasse Tyson with lots of actual space and rocket videos. Check it out! Don't have Netflix? Looks likes some full length copies on YouTube as well.
