What robots have been sent to Venus?

Two prominent missions have sent robots to Venus: the Soviet Venera program and NASA's Magellan spacecraft. The Venera probes, launched between the 1960s and 1980s, were the first to successfully land on Venus and transmit data back to Earth, including images of the surface. NASA's Magellan, launched in 1989, used radar to map the planet's surface extensively. These missions have provided invaluable insights into Venus's atmosphere and geology.
