    Two Japanese satellites, also known by the national name of Ayama (“expansion”) launched by NASDA (National Space Development Agency) to carry out millimeter-wave communications experiments. However, both failed – ECS because the third stage of the N-1 launch vehicle came in contact with the satellite after separation, and ECS-B because of a fault with the apogee kick motor.

    Launch vehicle N-1
    Launch site Tanegashima
