Hi Again DA,

Taking swabs from the space station might not have the level of control that one might desire. The problem is that it is too close to the atmosphere. I would expect contamination. However, the idea of "sample retrieval" actually has some merit.

The case for the terrestrial development of life is not without merit. Again the question is where to look for evidence. Have a look at this:

These guys still have lots of work to do, but it is kind of neat.
