A truck moves NASA's MAVEN spacecraft, inside a payload fairing, from the Payload Hazardous Servicing Facility, or PHSF, to Space Launch Complex 41 where it will be hoisted atop a United Launch Alliance Atlas V rocket that will lift it into space and on to Mars. MAVEN is short for Mars Atmosphere and Volatile Evolution. Photo credit: NASA/Kim Shiflett
