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".

Outside Mars, Jupiter was first visited by "Pioneer 10" in 1973. More than 20 years later "Galileo" sent a probe into the planet's atmosphere, and became the first spacecraft to orbit the planet. "Pioneer 11" became the first spacecraft to visit Saturn in 1979, with "Voyager 2" making the first (and so far only) visits to Uranus and Neptune in 1986 and 1989, respectively. The first spacecraft to leave the solar system was "Pioneer 10" in 1983. For a time it was the most distant spacecraft, but it has since been surpassed by both "Voyager 1" and "Voyager 2".
