1996-046A
The ADEOS satellite was launched in Aug 1996. NASDA's ADEOS Advanced Earth Observing Satellite was built by Mitsubishi Electric of Tokyo. The 3200 kg satellite has a 4m x 4m x 5m bus with a 3 x 13 m solar array. It carries a payload to study the ozone layer and the greenhouse effect, as well as an inter-satellite communications experiment. The satellite was named Midori (`green') on reaching orbit, but the ADEOS name was almost always used.
The main 20N thrusters malfunctioned, and initial orbit adjust was made by the small 1-N thrusters. In June 1997 the solar panels failed structurally and the spacecraft was lost.
