TIROS-10 (also called TIROS OT-1) was a spin-stabilized

meteorological satellite. It was the tenth and last in a series of Television Infrared Observation Satellites
.

Launch

TIROS-10 was launched on July 2, 1965, by a

apogee was 837 kilometers (520 mi).[1]

Mission

TIROS 10 was a

Electric energy was supplied to the spacecraft by approximately 9000 1-by 2-cm silicon solar cells
that were mounted on the cover assembly and by 21 nickel-cadmium batteries. A single monopole antenna for reception of ground commands extended from the top of the cover assembly.

. Proper attitude was maintained to within a 1° to 2° accuracy by use of a magnetic control device consisting of 250 coils of wire wound around the outer surface of the spacecraft. The interaction by the induced magnetic field in the spacecraft and the Earth's magnetic field provided the torque necessary for attitude control.

The satellite spin axis could thus be varied while the satellite remained in the conventional TIROS "axial" mode. The satellite was equipped with two identical wide-angle TV cameras with 1.27-cm vidicon for taking earth cloudcover pictures. The pictures could be transmitted directly to either of two ground receiving stations or stored in a tape recorder on board for subsequent playback if the spacecraft was beyond the communication range of the station.

The satellite was launched into a near-polar orbit and successfully provided TV coverage of the entire daylight portion of the Earth. The TV system operated normally until September 30, 1965, and sporadically through July 31, 1966, when the spacecraft was deactivated.[3]
