The White House announced on February 1, 2010 that the NPOESS satellite partnership was to be dissolved, and that two separate lines of polar-orbiting satellites to serve military and civilian users would be pursued instead:
  • The NOAA/NASA portion is called the Joint Polar Satellite System (JPSS)
    Joint Polar Satellite System (JPSS)
    Joint Polar Satellite System 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...
