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 EO Vista providing the sensor payload. After a protest by SSL, the contract with SNC was rescinded in January 2018 with further steps to be determined.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.
