Blue Sky on Mars
The cover of the album features an image by Viking 1, the first spacecraft to land on Mars; the album's liner notes include additional imagery of the planet's landscape as taken by the spacecraft on July 20, 1976. The text on the cover was done by fantastic artist Roger Dean, best known for his work on album covers for bands such as Yes. The album's title comes from the tour in the film "Total Recall".
Mars Pathfinder
Mars Pathfinder (MESUR Pathfinder) is an American robotic spacecraft that landed a base station with a roving probe on Mars in 1997. It consisted of a lander, renamed the Carl Sagan Memorial Station, and a lightweight (10.6 kg/23 lb) wheeled robotic Mars rover named "Sojourner", which became the first rover to operate outside the Earth–Moon system.
