It was because of all this evidence --- and
perhaps some leftover motivation from
Percival Lowell --- that NASA decided to
equip its Viking landers (in the 1970s)
with experiments to search for life on
Mars.
We will talk about the details of
these experiments and their
complicated, confusing results ---
everyone knows there's no life on
Mars, right? Right? Hmm. --- in a
couple of weeks when we talk about searches
for life in the Universe.
For now, you might want to think about
how you would design (from scratch) an
experiment to be sent to Mars to
search for life.
You get to start from scratch
here. What would you do? How would you
do it?
