Venera 16 arrived at Venus at 06:22 UT on 14 October 1983 after en route course corrections on 15 June and 5 October 1983. It began its mapping operations six days later in its 24-hour-period near-polar orbit.
Mapping resolution of both Veneras 15 and 16 was comparable to that possible with the 300-meter dish at Arecibo in Puerto Rico, although the Soviet orbiters provided coverage over latitudes higher than 30° - too far north for Earthbased observations. Both spacecraft also used an East German infrared spectrometer to map the planet in infrared wavelengths in order to provide a heat atlas of the atmosphere.
Although the primary missions of both spacecraft were fulfilled by 10 July 1984, at least one of the pair was still operational in November 1984. If there were plans to change its orbit to provide coverage of lower latitudes, these were never carried out.
