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".
Luna 16
"Luna 16" was the first robotic probe to land on the Moon and return a sample of lunar soil to Earth after five unsuccessful similar attempts. The sample was returned from Mare Fecunditatis. It represented the first lunar sample return mission by the Soviet Union and was the third lunar sample return mission overall, following the Apollo 11 and Apollo 12 missions.
