The mission
JPSS 1 (Joint Polar Satellite System spacecraft No. 1)
From a 512-mile orbit, tilted 98.7 degrees to the equator and traveling pole-to-pole, the craft will provide imagery, atmospheric temperature and humidity profiles, and land and ocean surface temperature observations, all of which are key ingredients for weather forecasting. In addition, the satellite will measure ozone levels and reflected solar radiation from the planet.JPSS 1 will survey the entire globe twice per day with five sensor packages.The satellite will replace the existing Suomi NPP spacecraft that launched in 2011 for a five-year mission as a gapfiller between NOAA’s legacy weather satellite constellation and the new JPSS generation.
