Fifth STEP (Space Test Experiments Program) satellite. The satellite's main section was the STRV-2 experiment module, sponsored by the Ballistic Missile Defense Organization and the UK Ministry of Defense. This was to take infrared images of UK military aircraft at perigee, and then downlink data via laser. STRV-2 also carried vibration isolation and debris impact sensors. A secondary payload was the S97-1 CEASE (Compact Environmental Anomaly Sensor). This was an AFRL prototype sensor package to provide warning of spacecraft charging and radiation events.
