Drake, Frank D. Project Ozma. Physics today, v. 14, Apr. 1961: 40-46.
Theory of the origin of life is given and possibilities of contact with intelligent
extraterrestrial life discussed. Author hypothesizes that frequencies near
1420.405 Mc/sec may be used by an extraterrestrial civilization attempting to
signal earth.
----- Radio emission from the planets. Physics today, v. 14, Apr. 1961: 30-34.
Predictions based on optical infrared studies of Venus, Mars, Jupit<:r, and
Saturn are compared with radio emission data. Biological significan.-:e of in-
frared surface conditions--based on radio emission data--is assessed.

pulsion Laboratory, 1965. p. 323-345.
It is concluded that microwave radio signals are the most common means of in-
terstellar communication; that terrestrial technology is capable of carrying on
a successful search for signals but that the project, if it is to cope with all the
reasonable possibilities, must be one of very great expense, complexity, and
duration. It is also suggested that there are many other possible ways in which
manifestation of intelligent Jife might be found, but at present few, if any, ap-
pear to offer enough hope of success to justify their active pursuit.

v. 131, June 3, 1960: 1667.
If extraterrestrial intelligent beings exist and have reached a high level of tech-
nical development, one by-product of their energy metabolism is likely to be the
large-scale convr.rsions of star-light into infrared radiation. It is proposed
that a search fo1· sources of infrared radiation should accompany the search for
inkrstellar communications.
