"In this book, Malcolm Walter focuses on the similarities between Mars and the early Earth. Utilizing his expert knowledge of microbial life in boiling hot springs on Earth, where many scientists believe life on our planet may well have originated, Walter unveils his dramatic plan - already adopted by NASA - for finding life in the rocks and subsurface water of Mars.

Then, taking a hard look at that alleged "fossil" in the now famous Mars-rock found in the Antarctic, Walter puts that find in perspective, showing that although the "evidence" therein was inconclusive, there are still many reasons that we should continue the search for life on our most written about planetary neighbor.".

"Finally, Walter gives us a glimpse of the future plans to search for life in the universe and drives home the importance of that search for a deeper understanding of our planet and the long-term future of humankind."--BOOK JACKET.
