The main source for this text is the National Space Science Data Center.
Venera 15 and 16 were a two spacecraft mission primarily designed to use 8 cm band side-looking radar mappers to study the surface properties of Venus. The primary instruments of each spacecraft were a synthetic aperture radar experiment and a radar altimeter experiment. Each spacecraft also carried an energetic particles experiment, an infraredFourier spectrometer, and a radio occultation experiment.
