NOAA retires polar-orbiting satellite
NOAA will continue operating several POES spacecraft — NOAA-15, NOAA-16, NOAA-18 and NOAA-19 — in addition to the nation’s newest polar-orbiting satellite, Suomi NPP, launched October 28, 2011. NOAA’s POES spacecraft fly a lower, pole to pole orbit capturing atmospheric data from space that feed NOAA’s weather and climate prediction models.
NOAA began the deactivation process of NOAA-17 on February 18, with the final shut down occurring today. Launched in June 2002, NOAA-17 made 55,000 orbits of the globe, traveling more than 1.5 billion miles while collecting huge amounts of valuable temperature, moisture and image data.
“NOAA-17 helped our forecasters see the early development of severe weather from tornadoes and snow storms to hurricanes, including the busiest hurricane season on record — 2005. It also tracked subtle changes in the environment that signaled the onset of drought and wildfire conditions,” said Mary Kicza, assistant administrator of NOAA’s Satellite and Information Service. “NOAA-17’s long life is a credit to the engineers who built and operated it and the technology that sustained it. Although we say farewell to NOAA-17, we still operate a dependable fleet of satellites that continue to provide crucial data.”
NOAA-17 was part of the international Search and Rescue Satellite-Aided Tracking (SARSAT) network of satellites. SARSAT, which began in 1982, has rescued more than 33,000 people worldwide, including more than 7,000 in the United States and its surrounding waters by detecting distress signals from emergency beacons.
Deactivating NOAA-17 also heralds a significant change for polar-orbiting satellite operations worldwide with NOAA now exclusively flying afternoon orbit spacecraft while its key international partner, the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), flies mid-morning orbit spacecraft. This results in significant savings for U.S. taxpayers, because sharing data helps produce more accurate and uniform data for forecasters. Through the Initial Joint Polar System agreement, NOAA and EUMETSAT established a shared satellite system by exchanging instruments and coordinating the operations of their polar-orbiting satellites to provide operational meteorological and environmental forecasting and global climate monitoring services worldwide.
NOAA and its partners at the National Aeronautics and Space Administration (NASA) are continuing to build the next generation of polar-orbiting satellites, the Joint Polar Satellite System (JPSS), which is scheduled to launch the JPSS-1 satellite in 2017.
NOAA’s JPSS represents significant technological and scientific advances for more accurate weather forecasting, helping build a Weather Ready Nation — saving lives and property, while promoting economic prosperity. JPSS provides continuity for critical observations of our vast atmosphere, oceans, land, and cryosphere — the frozen areas of the above planet. NOAA, working in partnership with NASA, ensures an unbroken series of global data for monitoring and forecasting environmental phenomena and understanding our Earth.
NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Join us on Facebook, Twitter, Instagram and our other social media channels.
