accomplished by various approaches: from earth;
SS Orne tentEe ns ae coeee ana misooa” or cirowplanctary satellites;
by crash landings; by “soft landings". Each epproach presents distinct
cpportunities; landings also present distinct dangers of contamination
that would obecure the primitive conditions of the planetary surface.

It ia urgently important for bialogists te evaluate present and forth-
coming knowledge of planetary conditions in relation to its possible
bearing on life phenomena.

a. An immediate study of planetary geography and physics
from the viewpoint of biclogy. Astronomers and biclo-~
cists showld be asked to cooperate in this evaluation
of swvailable knowledge.

>. Machinery for the prospt dissemination of new informa-
tion on the planets among Biologists should be set w.
a.

e.

Research on the manifestations of life phenceens that
might be detectable at each stage of exploration and
on the devices for this should be stimilated through

an international basis.

Criteria for acesptable “calculated risks" should be
discussed and, if possible, agreed vpon internationally.

An initial international meeting of interested biclo-
giste and astronomers could be organised, possibly in
connection with the Memorial. Conference
at the University of Pavia, Italy, on May 7 to 9,
1999.
