NIMBUS-NIM I--------
SATELLITE DESCRIPTION:
The spacecraft was designed in two sections. The lower circular ring housed the meteorological sensors and electronics. The upper hexagonal section contained the attitude control system and had two solar panels (containing 10,500 individual panels) attached to its sides. The two sections were constructed by a magnesium truss. The lower ring was 57 inches in diameter. The total spacecraft height was 118 inches while the width across the solar panels was 134 inches. The total weight of the spacecraft was 830 pounds.
The craft contained three cameras with direct readout and delayed readout capabilities. A high resolution infrared radiometer operated in the 3.4 to 4.2 micron region. Two horizon scanners, sun sensors and freon gas jets provided the attitude control.
