Summary
MICROSAT 6, also known as Microsat 6, is an experimental communication satellite launched by DARPA on July 17, 1991, from AFWTR using the Pegasus/HAPS launch vehicle. The spacecraft has a cylindrical shape with dimensions of 0.2 meters in length and 0.5 meters in diameter and span. It has a dry mass of 19 kg and a launch mass of 21 kg. MICROSAT 6 was equipped with a 1 UHF transponder digital store and forward communications system, powered by solar cells and batteries. The satellite utilized cold gas N2 propulsion for its motor. Its mission aimed to conduct experimental communication operations but only achieved one year in orbit despite a planned four-year lifetime.
