One of the technologies to make the future planetary exploration more flexible and valuable is a vehicle which can fly freely in the Martian atmosphere. Our group proposes a paraglider which has a flexible and inflatable wing. The paraglider has a large and light wing which can be packed compactly in the launch and cruising phase. To realize this idea, free flight test from high altitude by the Atmospheric balloon must be carried out. However, it is difficult to succeed flight test from beginning. Therefore, we’re going to carry out a relatively simple flight test from low altitude. In this study, result of flight test was reported.
