How can you study Mars without a spaceship? Head to the most Martian place on Earth -- the Atacama Desert in Chile. Astrobiologist Armando Azua-Bustos grew up in this vast, arid landscape and now studies the rare life forms that have adapted to survive there, some in areas with no reported rainfall for the past 400 years. Explore the possibility of finding life elsewhere in the universe without leaving the planet with this quick, funny talk.
