I'm glad David posts there, Tom! I feel the same way about that post of his. Except for this one:

5. If there was ever life of any kind on Mars, some form of it has survived to the present day. This conclusion is due to the incredible adaptability and tenacity of life.

* That's true, but it's the last sentence in that 5th section that I wonder about:

This life will be able to live in the absence of liquid water.

* I believe that that is pretty unlikely. As we all know, life can live and survive in desert like conditions, but it even rains in our deserts. Another way that primitive, microbial life can survive in such an 'environment' is if it had predator instincts and even fed on fellow or similar life. Even so, H20 in some liquid form, morning dew, humidity in the atmosphere, etc., is vital.

(From reading below from Alex) I hope that they will highly consider using a SAT type satellite soon.
