Charles Elachi shares stories from NASA's legendary Jet Propulsion Lab -- including tales and video from the Mars Rover project. This video shows incredible footage of Mars, including pictures of a BLUE atmosphere, and dessert terrain that looks much like something taken at a Nevada desert site... The video's 28 minutes long and is VERY informative. I highly recommend checking it out. Below is a screenshot I took of the video, which shows a rover at Mars' north pole.
