Upper-Atmosphere Heating at High Latitudes.
Abstract
The orbit of Molniya 1K (1968-85A) from November 1968 to November 1970 has been analysed to study variations in air density near 65 degrees S. This object is unique among the Molniya satellites in that its perigee height, which varies with a 7-year period due to luni-solar forces, reached a minimum near 400 km about a year after launch. The air density is sampled over very short arcs because of the high eccentricity (0.74), and the sampling is confined to two small regions of the earth since the orbit is 2:1 commensurable with the earth's rotation.
