Two projects are introduced in this paper to verify the performance of space tether technology. A sounding rocket will be launched in the summer of 2009 to deploy a bare electro-dynamic tape tether having a length of 300 m. The other project to verify the space tether technology is a small satellite to deploy a bare 25 km electro-dynamic tape tether, and the launch is expected in 2013 with employing a new solid motor rocket. These verifications of tether technology will lead to a large numbers of applications of space tether technology and some future projects are also introduced. 資料番号: AA0063706026

We present proposals for observing the plasma transportation and circulation processes and the dynamics of the thermal plasmas that are the important element on Venus ionosphere by instruments installed on Venus Climate Orbiter. Main purpose of the observation is to elucidate the following unresolved problems: 1) How the upper atmosphere interacts with the lower atmosphere. 2) How much the energy of the solar wind can enter to the Venus upper atmosphere. 3) How momentum and energy of particles are transported into the upper atmosphere from external regions through the coupling process. In the presentation, the observation target and strategy will be discussed in detail.
