NATIONAL ACADEMY OF SCIENCES NATIONAL RESEARCH COUNCIL OF THE UNITED STATES OF AMERICA SPACE SCIENCE BOARD 17 August 1959 Dy. Thomas Francis, Jr. Professor end Chairasn paper tment of Epidemiology University of igan ann Asber, Michigan Dear br. Francis: I was delighted to learn from Keffer Hartline of your willingness to serve on his Committee on the Blolegical Aspects of Space Science of the Space science Board. Both t ine and I have found the plological aspects of Space science emong the most difficult te treat. There are an of good comaittees in the field of “man- space" and related matters, and Dr. Cannon of NAC is coopereting in making the data from these comaittees aveilable to the Sosrd. There is, however, s problem in evaluating the diverse work in the field. More important are three other aspects of the space biology program: } &} Biological experimentation unique to space. b) Contamination of the moon and planets upon lending (and equally, beck contamination on return, ) ¢) Expleretion of extre-terrestrial objects by man, and biolegical objectives in such exploration. while extra-terrestrial exploration by man is still a few years away, the problem of contamination of extra-terrestrial biological forms from the Earth is iamediate end is receiving attention froa Leder « Both physicists and plologists are interested in extre- terrestris] forms and evolutionary patterns involved, so that such Study is ahead in determining the best precedures in developing extré-terrestrial exploration. #ith every good wish, Sincerely yours, L.
