This DVD, part of the publisher's "Space" series, is essentially a compilation of footage from the mid-1970s, when NASA sent twin lander spacecraft, the famous Vikings, to the surface of Mars. It's a portrayal of a time when so little was known about the red planet that the possibility of complex life forms roaming the surface, and lush vegetation covering the surface of the planet, was still being taken seriously. How much times have changed. The experiments the Viking landers performed to look for life were inconclusive; the results are still being debated. But what we can say is that Mars is a world in deep-freeze, where complex life seems highly unlikely.

The DVD lasts one hour and would be of interest to anybody interested in the exploration of Mars, and in particular the two spacecraft which changed our view of the red planet forever. A nice DVD to have in your collection.
