I was thinking about this earlier after watching a few specials on space exploration. Maybe this has already been done, maybe its already been thought of, I dont really know... I know we have sent rovers to mars in search of many things, the most important of which would be alien life forms. Obviously, discovering life on another planet would be the greatest discovery of mankind. Heres my question: What if we sent simple life forms along with these rovers, not only to mars, but to other celestial bodies as well. What if these rovers could somehow release these simple life forms into the enviornment around them and see what happens. The rovers could study them and send back information about the condition of the life forms over a certain period of time. Now to the main question: IF (and I know its a stretch) some of these simple life forms were able to adapt somehow and continue to live, would the significance be as great as finding alien life on another planet? If nothing else, it seems like it would be very interesting to see how earthly life forms interact with an alien enviornment, no?
