and much supporting research done. Important projects incorp- 

 orated in our space program are addressed to the question of the 

 detection of extraterrestrial organic compounds and to determin- 

 ing the distribution of life in the solar system. What appeared, 

 when this lecture was presented, as an almost purely academic 

 consideration is now a central question in a large national pro- 

 gram.
