Photos: JPSS-1 Satellite Installed on Delta II Rocket

The JPSS-1 weather satellite was installed atop its Delta II launch vehicle on October 24, 2017 for final integrated testing ahead of a November 2017 liftoff to relieve the Suomi NPP satellite and become the primary polar-orbiting weather asset of NOAA and the U.S. National Weather Service. This will be the penultimate Delta II mission as the vehicle prepares to sail into retirement in 2018 after a career of nearly three decades.
