Stratospheric Aerosol and Gas Experiment , SAGE for short , or Explorer-60 and AEM-2 was a research satellite of NASA's Explorer program .
equipment
SAGE was a small, versatile, inexpensive spacecraft made from two different parts;
- the SAGE instrument module with the detectors and the associated hardware and
- the base module which contains the necessary data handling, power, communication, command and setting control subsystem to support the instrument mode.
In addition, there were many small experiments on board, for example some sun sensors and a magnetometer.
mission
The aim of the SAGE mission was to obtain stratospheric aerosol and ozone data on a global level in order to enable a better understanding of the environmental quality and the earth's radiation budget. Later the SAGE instruments were also mounted on other satellites: SAGE II was mounted in the ERBS and SAGE III in the Meteor-3M satellite (originally planned for EOS B).
begin
SAGE was launched into space on February 18, 1979 with a Scout D1 launcher from Wallops Island Flight Facility LA 3. After a day he unfolded his solar cells. He carried out the first experiments on February 22 of the same year.
Operation and failure
The spacecraft was designed to last for 1 year in orbit. It was powered by two solar cells and batteries. For more than a year, SAGE carried out numerous experiments. After May 15, 1979, he had electricity problems and switched off some experiments to save energy. The satellite lasted until November 19, 1981. The last SAGE signal was received on January 7, 1982, after which the battery failed.
