Description published by the archive
Venera 11 and Venera 12 were twin Soviet missions, launched five days apart, to study Venus and the interplanetary medium. Both missions comprised a flight platform (bus) and a descent craft (lander probe). The flight platform had instruments to study solar-wind composition, gamma-ray bursts, ultraviolet radiation, and the electron density of the ionosphere of Venus. The lander probe carried instruments to study the characteristics and composition of the atmosphere and surface of Venus.
