NOAA-20 Visible Infrared Imaging Radiometer Suite (VIIRS)

JPSS-1, now known as NOAA-20, is the second spacecraft within NOAA's next generation of polar-orbiting satellites which was
launched in November 18, 2017. Capitalizing on the success of Suomi NPP, the JPSS-1 spacecraft boasts five similar instruments:
(1) VIIRS, (2) CrIS, (3) ATMS, (4) OMPS-N, and (5) CERES-FM6. Instruments can also be called sensors or payloads. JPSS-1 will take advantage of the successful technologies developed through the Suomi NPP satellite. JPSS-1's design life is seven years. The Visible Infrared Imaging Radiometer Suite (VIIRS) is one of the key instruments onboard the NOAA-20 spacecraft. It collects visible and infrared imagery and global observations of land, atmosphere, cryosphere and oceans.

Mission Notice :

11/29/2017: After JPSS-1 launched into Earth orbit, the satellite, now known as NOAA-20, has sent back its first Advanced Technology Microwave Sounder (ATMS) science data.

11/18/2017: The Joint Polar Satellite System-1, the first in a new series of four highly advanced NOAA polar-orbiting satellites,
lifted off from Vandenberg Air Force Base, California, at 1:47 a.m.
