Summary
OPTUS A2 (AUSSAT 2), also known as Aussat K2, is an Australian communication satellite launched on November 27, 1985, from Kennedy Space Center's LC39A pad aboard a Space Shuttle. The spacecraft has dimensions of 6.6 meters in length and 2.2 meters in diameter with a span of 6.3 meters. It was manufactured by HSES and equipped with 15 Ku-band transponders operating at 14/12 GHz for its communication mission. With a dry mass of 433 kg and a launch mass of 566 kg, the satellite uses solar cells (body mounted and drop-skirt) along with batteries for power supply. Its shape is described as Cyl + 2 Dish, and it was designed to operate for approximately 7 years in orbit.
