Shin'en 2



Shin'en 2 is an interplanetary spacecraft built by students at the Kyushu Institute of Technology and Kagoshima University in Japan that carries a 145-MHz up/435-MHz down transponder into a deep space heliocentric orbit. The spacecraft is semi- globular shape with 500-mm diameter. The body structure is made of a lightwight Carbon Fiber Reinforced Thermo-Plastic (CFRTP) and the mass is approximately 18 kg. It is powered by solar cells on the polyheadral surface of the spacecraft body. Shin'en 2 orbits the Sun in an elliptic orbit between Venus and Mars. Its inclination is almost zero, which means Shin'en 2 stays in the Earth’s equatorial plane. The distance from the Sun is between 0.87 and 1.07 AU.

The goals of the mission are to establish communication technologies with a long range as far as moon and establish a new technology of the ultra-light-weight satellite and establish of a measurement technology of the cosmic radiation with nano-size spacedcraft. This cosmic radiation sensor was developed by Prairie View A&M University, Johnson Space Center of NASA and the University of Nevada.
