Venera 16 (Russian: Венера-16 meaning Venus 16) was a spacecraft sent to Venus by the Soviet Union. This uncrewed orbiter was to map the surface of Venus using high resolution imaging systems. The spacecraft was identical to Venera 15 and based on modifications to the earlier Venera space probes. The latest data from the spacecraft were received on June 13, 1985, when it responded to the signal sent from Earth for Vega 1.
