Spirit's Winter Work Site
Forty-three years ago today on Nov. 28, 1964, NASA launched Mariner 4 en route to the Red Planet. The spacecraft flew past Mars on July 14, 1965, collecting the first close-up photographs of another planet. Since then, NASA has placed several spacecraft on the surface of Mars, as well as several orbital missions.
This image, acquired by the Mars Reconnaissance Orbiter, shows the Mars Exploration Rover Spirit's 2006 winter campaign site.
