About Misty

Zirconic was a National Reconnaissance Office (NRO) codename for a program established under the Presidency of Ronald Reagan to develop reconnaissance satellites equipped with stealth technology. Zirconic operated as a sensitive compartmented information program and included the Misty spacecraft, designed to reduce radar, visible, infrared, and laser signatures. Access to related classified material required a dedicated "Zirconic clearance", and the program's development effort was internally codenamed Nebula.
