The Suomi NPP Satellite
Over the last decade NASA launched a series of satellites that offer an unparalleled view of Earth from space. That series, known collectively as NASA's Earth Observing System (EOS), has provided striking new insights into many aspects of Earth, including its clouds, oceans, vegetation, ice, and atmosphere. However, as the EOS satellites age, a new generation of Earth-observing satellites are poised to take over.
The Suomi National Polar-orbiting Partnership represents a critical first step in building this next-generation satellite system. Suomi NPP orbits the Earth about 14 times each day and observe nearly the entire surface. The NPP satellite continues key data records that are critical for climate change science.
The Suomi National Polar-orbiting Partnership spacecraft lifted off at 5:48 a.m. EDT on Oct. 28, 2011, to begin its Earth observation mission. The spacecraft was lifted into orbit by a United Launch Alliance Delta II rocket launching from Vandenberg Air Force Base, Calif. The launch capped a flawless countdown.(source: GSFC)
