Dear Dr. Lederberg:
Many thanks for your letter of October 15, 1963 and the reprints.

Knowing of your interest in space research I thought you had probably been
in touch with COSPAR. In any case I will pass on your comments and also
distribute the paper to those who make enquiries. There have been six
requests for the data sheets but it is difficult to know how many of these
are from curiosity and how many are really interested. So far there have
been no comments.

I realize that several at Camp Detrick have been interested in the
sterilization of space craft but these, like yourself, have had an
opportunity of presenting their views to COSPAR. Are there any others in
the U.S.A. who are not in this position and who might be able to give a
considered opinion?

For your information, a copy of Dr. Kellogg's data sheets is enclosed.

Sincerely,

VA

N. E. Gibbons
