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".
Life on Mars
Mars-1 was the first spacecraft launched to Mars in 1962, but communication was lost while en route to Mars. With Mars-2 and Mars-3 in 1971-1972, information was obtained on the nature of the surface rocks and altitude profiles of the surface density of the soil, its thermal conductivity, and thermal anomalies detected on the surface of Mars. The program found that its northern polar cap has a temperature below -110 °C and that the water vapor content in the atmosphere of Mars is five thousand times less than on Earth. No signs of life were found.
