Television Infrared Observation Satellite Television Infrared Observation Satellite TIROS, or Television Infrared Observation Satellite, 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"
Weather System Follow-on Microwave Weather System Follow-on Microwave The Weather System Follow-on Microwave (WSF-M) Satellite is the United States Department of Defense's next-generation operational environmental satellite system. WSF-M will be a Low Earth Orbit (LEO) satellite with a passive microwave imaging radiometer instrument and hosted furnished Energetic Charged Particle (ECP) sensor. WSF-M will be the first satellite in the Weather System Follow-on (WSF) program. Following the cancellation of the National Polar-orbiting Operational Environmental Satellite System (NPOESS), the Air Force pursued development of a new weather satellite under the Defense Weather Satellite System (DWSS) program. However, when that system faced delays and funding issues, the
