On the 40th anniversary of the moon landing, we look at the feasibility of a human voyage to the Red Planet. A manned Mars mission is a dream of many astro-philes, but such a trip poses huge challenges: the logistics of carrying food, fuel and water, astronaut fatigue and psychological demand, delays in communication, danger and, an $18 billion price tag. We’ll talk about why some say it is important to land humans on Mars, what could be in its way, and how we might get around those challenges.

Guests

• Susan Hassler, editor in chief of IEEE Magazine, which features Mars in its June’s issue
• John Gianforte, astronomy instructor for the Granite State College and cofounder of the Astronomical Society of Northern New England
