TIROS-7  

Definition

  • Objectives: Continue research and development of the meteorological satellite information system; obtain improved data for use in weather forecasting, especially during hurricane season. Description: The spacecraft was 42 inches in diameter, 19 inches high and weighed 270 pounds. The craft was made of aluminum alloy and stainless steel then covered by 9200 solar cells. The solar cells served to charge the nickel-cadmium (nicad) batteries. Three pairs of solid-propellant spin rockets were mounted on the base plate. TIROS-7 was also designed to make infrared measurements of reflected solar and terrestrial radiation over selected spectrum ranges and gather data on electron density and temperature in space. To accomplish this new expanded mission, TIROS-7 carried two wide-angle camera systems, a magnetic tape recorder, and infrared experimentation equipment. The electron density and temperature probes were the same as the ones flown on board Explorer 17. The spacecraft operating system still included the infrared horizon scanner, the north direction indicator, despin weights and spinup rockets, and the magnetic attitude control system. TIROS-7 was deactivated after furnishing over 30,000 cloud photographs; it lasted the longest of the TIROS series thus far, 1809 days. (en)
