Definition
- IBSS (Infrared Background Signature Survey) Launch: April 28,1991 Landed: May 6, 1991 Dedicated Department of Defense mission. Unclassified payload included Air Force Program-675 (AFP-675); Infrared Background Signature Survey (IBSS) with Critical Ionization Velocity (CIV), Chemical Release Observation (CRO) and Shuttle Pallet Satellite-II (SPAS-II) experiments; and Space Test Payload-1 (STP-1). Classified payload consisted of Multi-Purpose Release Canister (MPEC). Also on board was Radiation Monitoring Equipment III (RME III) and Cloud Logic to Optimize Use of Defense Systems-1A (CLOUDS-1). The Infrared Background Signature Survey (IBSS) Program was a Department of Defense (DoD) Ballistic Missile Defense Organization (BMDO) project flown on the Space Shuttle STS-39 mission in 1991. IBSS instruments included the IR Sensor, the Arizona Imager/Spectrograph (AIS), and two Low Light Light Level TV (LLLTV) cameras which were mounted on the improved Shuttle Pallet Satellite (SPAS II). Data was taken with SPAS II in a free-flying deployed mode, while attached to the Remote Manipulator System (RMS) and inside the Shuttle bay. The IR sensor was composed of two sensors, a radiometer and a spectrometer. The AIS istrument was composed of nine grating spectrographs and twelve optical imagers. The LLLTV instrument consisted of two cameras operating in the visible region of the spectrum. For more information, link to "http://www-pao.ksc.nasa.gov/kscpao/chron/sts-39.htm" (en)
