COMETS (Communications and Broadcasting Experimental Test Satellite)
A Japanese communications satellite launched by NASDA (National Space Development Agency); it is also known by the national name Kakehashi (“bridge”). COMETS carries Ka-band communications and intersatellite data relay payloads (see frequency bands). Although premature shutdown 44 seconds into the H-2 second stage burn put the satellite into a much lower orbit than intended, the onboard Unified Propulsion System was able to raise the orbit to a more useful height.
