Summary
MOLNIYA 1-82, also known as Molniya-1, is a communication satellite launched on August 1, 1991, from the Plesetsk Missile and Space Complex (PLMSC) using a Molniya 8K78M launch vehicle. This satellite has dimensions of 4.4 meters in length, 1.4 meters in diameter, and an 8.6-meter span. It had a dry mass of 1620 kilograms and was launched with a total mass of 1670 kilograms. The spacecraft is designed for a three-year lifetime and is equipped with six deployable solar arrays and batteries to provide power. MOLNIYA 1-82 operates in a Molniya orbit, which is typical for satellites providing communication services to high latitude regions, particularly in Russia. It was manufactured by NPOPM (NPO Precision Mechanics) and carries the Molniya-1T No. 90L payload. The satellite's shape consists of a cylinder with six panels.
