Solar Array Membrane Prototype for the OPENS-0 Small Saturn Probe

The Institute of Space and Astronautical Science at Japan Aerospace Exploration Agency is actively engaged in the research and development of a cutting-edge lightweight deployable solar array paddle, called solar array membrane. This technology is specifically designed for small satellites, with a particular focus on the OPENS-0 small probe for the Saturn flyby engineering demonstration. This paper provides the current status of the development of the full-scale prototype for the 9 m2 solar array membrane.
