Posted: November 20, 2000
The SAC-C spacecraft is an international mission to study the structure and dynamics of the Earth's atmosphere, ionosphere and geomagnetic field. SAC C's scientific mission is to:
The SAC C payload comprises 11 different instruments. NASA is responsible for two instruments/components of the SAC-C complement. The two NASA provided instruments are both provided by JPL,
The Scalar Helium Magnetometer (SHM) will be part of the Danish Magnetic Mapping Payload (MMP). The SHM will complement other MMP instruments and will be mounted at the tip of the Danish extendable boom. The SHM electronics box will be mounted on the spacecraft's lower (propulsion) platform.
Mulitspectral Medium Resolution Scanner (MMRS), provided by the Argentines will study the condition and dynamics of the terrestrial and marine biosphere and environment. The MMRS will be operational over Argentina during SAC-C's lifetime.
High Resolution Technological Camera (HRTC) will improve part of the MMRS scenes. The HRTC will be operational over Argentina during the lifetime of SAC-C.
Influence of Space Radiation on Advanced Components (ICARE) experiment will measure high energy radiation environment, trapped particle intensities and energy distribution and correlate them with advanced electronic components degradation. ICARE will be able to conduct regular environment characterization campaigns for ten days every six months and exceptional ones during solar events. ICARE will study the effects on components and their variations along the same time frame.
Italian Star Tracker (IST) will test a fully autonomous system and orbit determination using a star tracker.
Whale Tracker Experiment will track the migratory route of the Franca whale. The experiment will be operational when the spacecraft is over the South Atlantic Ocean.
Italian Navigation Experiment (INES) and its components will be the primary navigation sensor by the SAC-C attitude and orbit control subsystem and a secondary attitude determination sensor.
Data Collection System will enable SAC-C to collect environmental data from low cost ground platforms.
Digital Transponder for Radio Amateur Communications will allow radio amateur communications.
High Sensitivity Camera (HCS) is a highly sensitive intermediate resolution camera. The HCS will be useful in forest fire and electrical storm detection.
