TIROS-TIROS V-------
SPACECRAFT DESCRIPTION:

The spacecraft was 42 inches in diameter, 22 inches high and weighed 285 pounds. The craft was made of aluminum alloy and stainless steel then covered by 9260 solar cells. The solar cells served to charge the 63 nickel-cadmium batteries.

This craft contained all of the instrumentation of TIROS IV as well as a north direction indicator, and despin weights and spinup rockets in an attempt to improve the craft's longevity. TIROS V was also launched at a higher inclination (58 degrees vs. 48 degrees on all previous flights) to provide better observations at higher latitudes. The orbit was elliptical instead of circular due to a Delta ground guidance failure. In addition the three radiation sensors had to be disconnected prior to launch when they failed preflight checks.

TIROS V pictures were the best to date, including the observation of ice break-up at northern latitudes. TIROS V was operational for 161 days.
