NPOESS resurrection?

摘要

When the White House cancelled the US National Polar-orbiting Operational Environmental Satellite System in 2010 it also tore up plans for a single satellite providing meteorological data for both civil and military users. It was to have replaced the military Defense Meteorology Satellite Program and the civilian Polar Operational Environmental Satellite series. However the launch of NPP. the NPOESS Preparatory Project that was to have paved the way for the single system, finally got off the pad on October 28 when a Delta 7920-10 launched the satellite from Vandenberg AFB, CA. Built by Ball Aerospace. NPP carries five instruments including microwave and infrared detectors as well as an ozone-mapping suite.
