Drs. Gil Levin and Patricia Straat were interviewed on The Space Show Saturday:

They argue their Viking labeled release experiment was positive for life. Dr. Levin must be in his 80's now. Glad to see he is still with us.

What Dr. Levin argued for that the Viking experiments more likely than not indicated life was very controversial since he made them soon after the Viking missions. The two main complaints against his view was the idea there were no organics on Mars and liquid water was not possible.

Now more and more evidence points to the fact organics do exist on Mars. And liquid water especially with the presence of salts to lower the freezing point can exist for short times on the Marian surface, enough for microbes to make use of.

For those interested, a detailed discussion of Dr. Levins views can be found in the book:

Dr. Straat has also recently written a book on the topic:
