The Magellan spacecraft was launched to study Venus by NASA on May 4th 1989.
There have been many space probes to Venus. Here are a few important ones: * Mariner 10 (NASA) * The Venera series of probes (Roscosmos) * Magellan (NASA) * Venus Express (ESA) (check related link)
NASA has no single address, but the link below will help you find the one you need (find the NASA Centers link on their home page).
the purpose was to make a global map of the surface of Venus
On the NASA website (nasa.gov), at the bottom-right corner you'll find a link, "contact NASA".
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.
