NASA's Jet Propulsion Laboratory continues to share great images of Mars, and this particular video helps you to realize how amazing the Spirit rover mission was over its six year mission. Between January 2004 and March 2010, the little craft was uncovering the mysteries of Mars. While we all talk of human missions, these images helped me to understand how fascinating the first glimpses of a new world can be, whether containing in a spacesuit or viewed via a robot. All of it impresses me.
