Sources Sought NATIONAL AERONAUTICS AND SPACE ADMINISTRATION Joint Polar Satellite System Cross-Track Infrared Sounder - Special Engineering Task Order Pool Increase: NASA Goddard Space Flight Center (GSFC) intends to issue a sole source new work modification to increase the special engineering/launch support Task Order Pool to the Cross-Track Infrared Sounder (CrIS) contract, NNG10XA06C with L3Harris Technologies, Inc. CrIS is a key instrument currently flying on the Suomi NPP, NOAA-20, and JPSS-2 satellites. CrIS gathers information on greenhouse gases, primarily in the middle and upper atmosphere. Both CrIS along with ATMS provide essential atmospheric sounder information for weather forecasting. This modification will allow special engineering/launch support to continue for JPSS-2, JPSS-3 & and JPSS-4 and will increase the special engineering/launch support task order pool by 23,000 hours.
