ORS 8 (Operationally Responsive Space 8) mission was planned as a gap-filling system to perform cloud characterization and theater weather imagery in place of the aging Defense Meteorological Satellite Program (DMSP-5D3) until WSF-E becomes available. The mission was managed by the US Air Force working with the NASA Ames Research Centerís small spacecraft prototyping office.
ORS-8, which was to be ready to launch in 2020, would receive $88 million in Fiscal 2018 budget proposal. ORS-8 was not to provide a long-term solution ó that requirement will be met by Weather Satellite Follow-on E (WSF-E). But because WSF-E has an initial launch capability date of 2023, ORS was asked for ORS-8 to provide environmental monitoring in the meantime, to be launched in 2020.
Sierra Nevada Corporation (SNC) was contracted to build the satellite, with Harris providing an updated version of its legacy sensor, the Advanced Very High Resolution Radiometer (AVHRR). After a protest by SSL, the contract with SNC was rescinded in January 2018 with further steps to be determined. ORS-8 was apparently cancelled in 2019 due to an extension of DMSP end-of-life.
