Mars is in our future.  In his book, "Life on Mars, what

to know before we go," Dr. David Weintraub tells us

all what to expect when we get there.  Listen in as

he talks about what we know about life forms, the

challenges of getting home, other planets that should

also capture our attention and even a glowing 

critique of the popular Matt Damon movie,

"The Martian," plus much more.  It's a fascinating

interview with Joe and one of his oldest friends who

now teaches at Vanderbilt and is one of the go-to

experts on the universe.  Enjoy.
