Abstract
Sculptors in the 20th century began their creation of sculptures with the challenge to release their art objects from weight and gravity, as it can be seen in the floating sculptures performed by Moholy-Nagy and Calder. 50 years after, these art experiments have been developed into the new art called ``0G Art (Zero Gravity Art)''. The present author commenced a joint study with JAXA, of the possibilities of Space Art in 2001 and has participated in the pilot mission of utilization of culture, humanities and social sciences, using ISS-JEM (International Space Station-Japanese Experiment Module) called ``KIBO''. Two of his art experimental projects titled ``Marbling Painting on a Sphere of Water'' and ``Spiral Top'' were conducted under this mission in 2008 and 2009.This thesis focuses upon the novelty of these two art experiments which applied dynamic efficacy, together with the issues and it also considers the possibilities of future ``0G Art''.
