TIROS-9 (also called TIROS-I or A-54) was a spin-stabilized meteorological satellite. It was the ninth in a series of Television Infrared Observation Satellites.

Launch

TIROS-9 was launched on January 22, 1965, by a Thor-Delta rocket from Cape Canaveral Air Force Station, Florida. The spacecraft functioned nominally until February 15, 1967. The satellite orbited the Earth once every 2 hours, at an inclination of 96°. Its perigee was 705 kilometers (438 mi) and apogee was 2,582 kilometers (1,604 mi). [1]

Mission

TIROS-9 was a spin-stabilized meteorological spacecraft designed to test experimental television techniques and infrared equipment. The satellite was in the form of an 18-sided right prism, 107 cm in diameter and 56 cm high. The top and sides of the spacecraft were covered with approximately 9000 1-by 2-cm silicon solar cells. It was equipped with 2 independent television camera subsystems for taking cloudcover pictures, plus an omnidirectional radiometer and a five-channel scanning radiometer for measuring radiation from the earth and its atmosphere. The satellite spin rate was maintained between 8 and 12 rpm by use of five diametrically opposed pairs of small, solid-fuel thrusters.

The TV system operated normally until April 1, 1965, when one of the wide-angle TV cameras failed. The other camera operated normally until July 26, 1965, and sporadically until February 15, 1967. TIROS 9 was the first satellite in the TIROS series to be placed in a near-polar orbit, thereby increasing TV coverage to the entire daylight portion of the Earth. [3]

Television InfraRed Observation Satellite (TIROS) is a series of early weather satellites launched by the United States, beginning with TIROS-1 in 1960. TIROS was the first satellite that was capable of remote sensing of the Earth, enabling scientists to view the Earth from a new perspective: space. The program, promoted by Harry Wexler, proved the usefulness of satellite weather observation, at a time when military reconnaissance satellites were secretly in development or use. TIROS demonstrated at that time that "the key to genius is often simplicity". TIROS is an acronym of "Television InfraRed Observation Satellite" and is also the plural of "tiro" which means "a young soldier, a beginner".

The Joint Polar Satellite System (JPSS) is the latest generation of U.S. polar-orbiting, non-geosynchronous, environmental satellites. JPSS will provide the global environmental data used in numerical weather prediction models for forecasts, and scientific data used for climate monitoring. JPSS will aid in fulfilling the mission of the U.S. National Oceanic and Atmospheric Administration (NOAA), an agency of the Department of Commerce. Data and imagery obtained from the JPSS will increase timeliness and accuracy of public warnings and forecasts of climate and weather events, thus reducing the potential loss of human life and property and advancing the national economy. The JPSS is developed by the National Aeronautics and Space Administration (NASA) for the National Oceanic and Atmospheric Administration (NOAA), who is responsible for operation of JPSS. Three to five satellites are planned for the JPSS constellation of satellites. JPSS satellites will be flown, and the scientific data from JPSS will be processed, by the JPSS – Common Ground System (JPSS-CGS).
