Akebono (known as EXOS-D before launch) is a satellite to study aurora and Earth's magnetosphere environment. It was developed by Institute of Space and Astronautical Science and launched by M-3SII rocket on February 21, 1989.

After 26 years of successful observation, operation was terminated on April 23, 2015, due to the degradation of solar cells and the decay of orbit.^[2]
