SPACE SCIENCE BOARD
MEMORANDUM April 5, 1960

TO: Members, Space Science Board
Members, Committee 11 and lla

At the request of Dr. Joshua Lederberg following recent discussions
of his Exobiology sub-committee, arrangements have been made to provide a
comprehensive discussion of very high altitude photography and the sub-
sequent interpretation of the photographs,

_,There appears much that can be learned by looking at pictures of the
earth taken from extreme altitudes which will be of direct application to
lunar and planetary near misses, For example, recent photographs taken at
700 miles from missile nose cones did not indicate to biologists either the
presence or absence of life on the earth. A better understanding of what
is now possible with expert photographic analysis cannot help but assist
those who are planning future lunar and planetary exploration,

Through the courtesy of General Don Flickinger, USAF (MC) of the Air
Research & Development Command, the Air Force will present a briefing
covering this topic to all who are interested on May 16, 1960, in the San
Francisco, California, area. The briefing will be held in either Palo
Alto or Berkeley and we shall advise you of the exact location prior to the
meeting. General Flickinger will introduce the speakers and be available
for discussion at the conelusion,.

Please let me know of your plans to attend,
