 According to Greek poet Homer Ares was a great Olympian god
 of war, whose divine attendants were his sons Phobos (Fear)
 and Deimos (Terror).

 Were Mars nuts realistic they would accept the fact that half
 a century could pass between manned exploration of the two
 moonlets and manned exploration of Mars itself.

 Hopefully future such exploration will be driven by engin-
 eering considerations rather than PR, especially if China
 is to take a leading part. 

 Therefore, the yardstick by which to judge rocketry of interest
 at present is not its capacity to land a posse of yankees on
 Mars and bring them safely back to a New York ticker parade,
 but its capacity to build Chinatowns on Phobos and Deimos.
