Talk title: Space Flight Mechanics of Solar Sail and Development Status for Future Potential Missions
Abstract:
Solar sail is a propellant-free propulsion system, which utilizes solar radiation pressure to produce thrust for orbit control. It is applicable to various missions from Earth orbits to cislunar and interplanetary regions. Following the success of IKAROS in 2010, we are currently studying advanced technologies of solar sails and trying to realize a new mission to demonstrate them using a micro spacecraft in space. In this seminar, we show the fundamentals of spacecraft dynamics with a solar sail, how they can apply to various missions, and the latest status of our research and development activities.

Talk title: Space Demonstration of Origami Deployable Array Antenna Using CubeSat
Abstract:
Membrane deployable structures are compactly stored during launch and deployed in orbit to enable various applications, such as solar-power generation arrays, array antennas, or solar sailing. At Tokyo Tech, 3U-size CubeSat OrigamiSat-2 is currently being developed for demonstration of deployable array antenna technology to be launched on the Epsilon rocket. This talk covers the structural and electrical technology behind the space demonstration.
