STEPS IN THE RACE TO OUTER SPACE. This 30-foot high Unicycle is designed for preliminary exploration of the Moon, once a base camp has been established. It's entirely constructed of inflated, rubberized fabric, with the exception of strengthening members, hatches and a few other items. Electricity for the motors comes from solar batteries mounted in the "parasol." The cleated, rotating wheel upon which the Unicycle travels is made of inflated tubes. A spare wheel, carried around the body, acts as a bumper in traversing narrow defiles. Living quarters make up a middle deck.
