Joint Polar Satellite System

The JPSS Mission

Information about our planet is vital to our ability to plan, predict, respond, and to protect lives and property. The Nation's system of polar-orbiting environmental satellites is vitally important and essential for supporting climate research as well as operational weather and storm forecasting for civil, military, and international partners.

JPSS will continue to address NOAA's requirements to provide global environmental data used in numerical weather prediction models for forecasts, as well as provide space weather observations, search and rescue detection capabilities, and direct read-out and data collection products and services to customers.

Data and imagery obtained from the Joint Polar Satellite System will increase timeliness and accuracy of public warnings and forecasts of climate and weather events, thus reducing the potential loss of human life and property and advancing the national economy. The program will better ensure continuity of crucial climate observations and weather data in the future.

Data from instruments on JPSS will be used to continue long-term, in some cases almost 50 years, of satellite-based climate data records. These data records are unified and coherent long-term environmental observations and products that are critical to climate modelers and decision makers concerned with advancing climate change understanding, prediction, mitigation and adaptation strategies, policies, and science. JPSS, with its global view, will play a vital role in continuing these climate data records.

Spacecraft and Instruments

JPSS Satellite with Earth

JPSS-1

JPSS-1, or NOAA-20 as it will be known once operational, is the second spacecraft within NOAA's next generation of polar-orbiting satellites. It is scheduled to launch in 2017.

Capitalizing on the success of Suomi NPP, the JPSS-1 spacecraft boasts five similar instruments: VIIRS, CrIS, ATMS, OMPS-N, and 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, and it is scheduled to launch aboard a Delta-II Mission Launch Vehicle.

JPSS-2

JPSS-2 will provide operational continuity of satellite-based observations and products for NOAA Polar-Orbiting Environmental Satellites (POES) and Suomi NPP satellite and ground systems. The baseline plan for JPSS Ground System will be sustained to support JPSS-2, similar to JPSS-1. The JPSS-2 spacecraft will host the following instruments: VIIRS, CrIS, ATMS, OMPS-N, and RBI.

JPSS-3

JPSS-3 is the fourth spacecraft within NOAA's next generation of polar-orbiting satellites. It is scheduled to launch in 2026. Benefiting from on the success of previous JPSS spacecrafts, JPSS-3 contains five instruments: VIIRS, CrIS, ATMS, OMPS-N, and RBI.

JPSS-4

JPSS-4, scheduled to launch in 2031, is the fifth spacecraft within NOAA's next generation of polar-orbiting satellites. Similar to previous JPSS spacecrafts missions, JPSS-4 will host five instruments: VIIRS, CrIS, ATMS, OMPS-N, and RBI.
