Abstract

The use of deployable membrane structures is expected for future large-area space structures, such as solar sails or large antennas, because they are lightweight and can be stored compactly at the launch. However, the technology to deploy sail membranes using centrifugal force had hardly been demonstrated ever. JAXA has studied the technology of spin deployment for long time. As one of the achievements, we have succeeded to deploy the 200 m2 class sail using centrifugal force in the IKAROS mission, which is the first solar sail demonstration in the world. The deployment of the sail was one of the most important missions of IKAROS. We could have shown the effectiveness of the developed deployment technology. JAXA is currently planning the spin deployment of a 2000 m2 class large sail as next generation spacecraft by sophisticating the technology and knowledge of IKAROS. This paper introduces the unexpected phenomena happened on orbit demonstration of IKAROS, as well as the problems of the deployment mechanism. Then, the improvement of the mechanism and its reflection status to the next mission are reported.
