Cosmos 1939



Cosmos 1939 was the fifth satellite in the Resurs-O1 series and the first to become operational. The Cosmos 1939/Resurs-O1 spacecraft was similar to the USA Landsat series and was designed to provide data for geologic applications, cartography, fire detection, ice monitoring, agriculutre and hydrology. The Resurs-O spacecraft was based on the Meteor-3 design and is three-axis stabilized. The spacecraft is about 5 m high and consists of 10 m solar pannels. Cosmos 1939 consists of 2 multispectral imaging systems: MSU-SK, a 5-channel multispectral conical scanner, and two MSU-E 3-channel pushbroom CCD imagers. The Resurs-O1 spacecraft were built by VNII Elecktromekaniki. The Resurs-O/Cosmos 1939 was preceeded by Meteor 1-30, Meteor 1-31, Cosmos 1484, and Cosmos 1689.
