This is a 0.1-pound thruster for controlling the attitude of the Applications Technology Satellite (ATS-6). The satellite had a total of 16 thrusters. The thrusters provided spacecraft orbit adjustment and attitude corrections. The satellite was launched in 1974 into a geostationary orbit of 22,300 miles above the Pacific Ocean.
It conducted a wide range of useful experiments including broadcasting lectures on farming techniques, hygiene, safety, family planning, and occupational skills to 5,000 villages in India. With the help of its thrusters, the satellite was later shifted to other locations to conduct a teachers conference broadcast to the Appalachian region of the U.S. and long distance medical diagnoses in Alaska. This object was donated to the Smithsonian in 1976 by the NASA Goddard Space Flight Center.
