COMETS (The Communications and Broadcasting Engineering Test Satellite) was a research and development satellite aimed at developing new technology in communications and broadcasting fields such as inter-orbit communications, advanced satellite broadcasting, advanced mobile satellite communications, and upgrading large geostationary satellites. It was to be used for conducting experiments and verifying the above subjects. The planned lifetime of the mission was to be three years, but a failure in the second stage of the H-II launch vehicle resulted in a highly eccentric orbit and prevented the spacecraft from attaining its planned geostationary orbit.
