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".
List of Mars orbiters
The Soviets' Mars program and NASA's Mariner program became the two first successful space programs that intended to explore Mars through orbiters. Mars 2, Mars 3 and Mariner 9 were all launched into space in May 1971, and all entered Mars’ orbit that same year. NASA's Mariner 9 reached the planet's orbit first on November 14, narrowly beating the Soviet's spacecraft amid the space race, and subsequently became the first spacecraft to orbit another planet.
