We are joined again by Big Brain Smart Head Bob, America's Favorite Rocket Scientist, and we discuss the very hard problem of getting to Mars.  Along the way, Zach and Rafe learn about lunar resources and gravity wells, develop a plan for a new energy drink (Lunar electric water!), and discover a whole new respect for the field of Botany.

Remember, if you have a question for Bob about going to Mars, send us a note at [email protected] and we'll make sure that Bob provides an answer!
