The National Polar-orbiting Operational Environmental Satellite System (NPOESS) was to be the United States' next-generation satellite system that would monitor the Earth's weather, atmosphere, oceans, land, and near-space environment. NPOESS satellites were to host proven technologies and operational versions of sensors that are currently under operational-prototyping by NASA. The estimated launch date for the first NPOESS satellite, "C1" or "Charlie 1" was around 2013. Issues with sensor developments were the primary cited reason for delays and cost-overruns.
NPOESS was to be operated by the NOAA / NESDIS / NPOESS Program Executive Office Flight Operations at the NOAA Satellite Operations Facility (NSOF) in Suitland, MD. Northrop Grumman Aerospace Systems (NGAS) was the primary system integrator for the NPOESS project. Raytheon, Ball Aerospace & Technologies Corp. and Boeing were developing the sensors.
NPOESS was to be a replacement for both the United States Department of Defense's DMSP and the NOAA Polar Operational Environmental Satellites (POES) series. The NPOESS Preparatory Project (NPP) was planned as a pathfinder mission for NPOESS. The project had to go through three Nunn-McCurdy reviews, Congressional hearings that are automatically triggered when a program goes over budget by more than 25%.[1] It was launched five years behind schedule, on October 28, 2011.[2][3]
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:[4]
