Status: To Be Determined
Mission:
The Electro-Optical/Infrared Weather System (EWS) Operational Demonstration-1 (OD-1) is a weather satellite for the United States Space Force. It is a prototype satellite made by General Atomics that will be place in LEO for a three-year demonstration mission of new EO/IR sensor technologies to various US military branches, and to act as a stop-gap for Defense Department needs for weather data.

Mission:
Also known as SensorSat, the Operationally Responsive Space 5 (ORS-5) will perform surveillance on geostationary (GEO) satellites. The craft will provide a stopgap for the existing space based surveillance system (SBSS), since full replacements are not expected until after 2020. With a mass of approximately 100kg the solar powered craft will operate in low earth orbit at an altitude of 600km.
