Humans to Mars: Fifty Years of Mission Planning, 1950-2000

This history should be seen as a tool for building
toward a future that includes piloted Mars exploration,
not merely as a chronicle of events forgotten and plans
unrealized. The author hopes to update and expand it
in 15 or 20 years so that it tells a story culminating in
the first piloted Mars mission. Perhaps a university
student reading this monograph today will become a
member of the first Mars mission crew tomorrow.
