NOAA-21, designated JPSS-2 prior to launch,[2] is the second of the United States National Oceanic and Atmospheric Administration (NOAA)'s latest generation of U.S. polar-orbiting, non-geosynchronous, environmental satellites called the Joint Polar Satellite System. NOAA-21 was launched on 10 November 2022[1] and joined NOAA-20 and Suomi NPP in the same orbit.[3] Circling the Earth from pole-to-pole, it will cross the equator about 14 times daily, providing full global coverage twice a day.[4] It was launched with LOFTID.
NOAA-21 will provide operational continuity of satellite-based observations and products for NOAA Polar-Orbiting Environmental Satellites (POES) and Suomi NPP satellite and ground systems.[4] The baseline plan for JPSS Ground System will be sustained to support NOAA-21, similar to NOAA-20. NOAA-21 hosts the following instruments: 1) VIIRS, 2) CrIS, 3) ATMS, and 4) OMPS. It was at one time intended to carry the Radiation Budget Instrument (RBI) but NASA canceled that project in 2018.[5]
