Summary
COSMOS 1843, also known as Kosmos-1843, is a reconnaissance satellite launched on May 5, 1987, from the TYMSC launch site using Soyuz-U as its launch vehicle. The satellite was designed and manufactured by TSSKB in SU (Soviet Union) and uses the Zenit bus configuration known as Oblik for its mission. It has a length of 6 meters, a diameter of 2.2 meters, and a span of 6 meters, with both dry mass and launch mass recorded at 2655 kg, indicating it did not carry additional fuel or payload beyond its operational components. The satellite's purpose is reconnaissance through photography using film return technology, and its propulsion system includes motors such as the 11D82M and S5.120 for maneuvering. COSMOS 1843 is powered by batteries and has a shape described as Sphere + DCone with a RCS of 27.97. Its payload, designated Oblik No. 355, contributes to its reconnaissance mission objectives.
