The search for life on Mars

Descripción

In the first of its two parts, The Search for Life on Mars gives us a unique portrait of Carl Sagan, the charismatic astrophysicist who more than any of this contemporaries has been identified with the possibilities of life in space. From Sagan, we move to the other principal scientists, and to the events of Viking on Mars - the biological experiments conducted on the two landing vehicles by remote control.
