Mission Category: Other
Launch Date: August 17, 1996
Launch Location: Tanegashima Space Center, Japan
Actual Completion Date: June 30, 1997

The Advanced Earth Observing Satellite (ADEOS) was the first international space platform dedicated to Earth environmental research developed and managed by the National Space Development Agency of Japan (NASDA) (The Japanese call her MIDORI). The TOMS instrument along with NSCAT (a NASA Spectrometer designed to study wind speed and direction) were a major US components of the platform. ADEOS launched on August 17, 1996 (at 01:53 UT) into a Sun-synchronous sub-recurrent orbit of an altitude of approximately 830 km by an H-II launch vehicle from the Tanegashima Space Center.

On June 30, 1997, the ADEOS Spacecraft failed and was replaced by NASA's EarthProbe/TOMS.
