and a few others.

About back-contamination, I had to give up on this
issue (for the moon) long ago. ‘The ritual at the
Houston center is a little ridiculous. The main point
is that a manned mission is fundamentally incompatible
with effective quarantine. (See encl. which puts it
very well.) However, I haven't tried to push that
much harder (1) to protect the credibility of quaran-
tine for Mars (2) it is hard to see how th moon can
sustain an earth-compatible flora (3) most important:
the earth has undoubtedly been 'contaminated' by lunar
material in quantity by ejecta from past cosmic events.

What was most preposterous about Apollo was the cal-
culated refusal to program useful science in situ, s0
as to save it for the dramatic manned landing, and

sample return.
