Summary
JPSS 1 (Joint Polar Satellite System spacecraft No. 1) launched on an United Launch Alliance Delta II 7920-10 from Space Launch Complex 2W, Vandenberg SFB, CA, USA on November 18, 2017. It was United Launch Alliance's 124th launch, 8th this year and humanity's 5,692nd orbital launch attempt. It was the 9th Delta II 7920-10 flight and the 1st this year. The payload was bound for Sun-Synchronous Orbit (SSO). NOAA-20, one of 6 catalogued objects, reached a 461 × 825 km orbit inclined 97.7°. 6 objects from this launch are catalogued, all of them payloads.

About this launch
From a 512-mile orbit, tilted 98.7 degrees to the equator and traveling pole-to-pole, the craft will provide imagery, atmospheric temperature and humidity profiles, and land and ocean surface temperature observations, all of which are key ingredients for weather forecasting. In addition, the satellite will measure ozone levels and reflected solar radiation from the planet.JPSS 1 will survey the entire globe twice per day with five sensor packages.The satellite will replace the existing Suomi NPP spacecraft that launched in 2011 for a five-year mission as a gapfiller between NOAA’s legacy weather satellite constellation and the new JPSS generation.
