Mission Description: The Joint Polar Satellite System (JPSS) is the nation's advanced series of polar-orbiting environmental satellites. JPSS represents significant technological and scientific advancements in observations used for severe weather prediction and environmental monitoring. These data are critical to the timeliness and accuracy of forecasts three to seven days in advance of a severe weather event. JPSS is a collaborative effort between NOAA and NASA.

JPSS satellites circle the Earth from pole-to-pole and cross the equator 14 times daily in the afternoon orbit--providing full global coverage twice a day.

Launch Notes: This launch will be ULA’s 123rd overall. This mission will mark the 53rd Delta II mission for NASA and 154th launch since the rocket’s first launch in 1989. Previous Delta II missions for NASA include the Spirit and Opportunity Mars rovers as well as Suomi NPP, the first next-generation polar-orbiting satellite in the JPSS series.
