We look at how the idea of moon travel has influenced pop culture over the past few decades. Then, Melissa Block talks with Dr. Robert Zubrin, president of the Mars Society and owner of Pioneer Astronautics, an aerospace engineering contracting firm. Zubrin is conflicted about the planned lunar base. The Mars Society maintains two testing grounds — in Utah and on an island in the Arctic — to simulate missions to other planets. Block also talks with Peter Kokh, president of the Moon Society. In March, Kokh and others borrowed the Mars Society's desert research station to simulate life on a lunar base. Kokh is mildly excited about NASA's plan to build an actual moon base.
