* Venera series (Soviet Union): A series of probes, starting in the 1960s, with Venera 9 and 10 being the first to successfully orbit Venus in 1975. These missions provided valuable data on the planet's atmosphere, surface, and composition.
* Magellan (NASA): Launched in 1989, Magellan used radar to map 98% of Venus's surface, revealing its volcanic features and tectonic activity.
* Venus Express (ESA): This spacecraft, launched in 2005, studied Venus's atmosphere, climate, and potential for past water.
* Akatsuki (JAXA): A Japanese probe, launched in 2010, entered orbit around Venus in 2015 after initial orbit insertion difficulties. It studies the planet's atmosphere and weather patterns.
While these are some of the most significant missions, there have been other probes and flybys to Venus, contributing to our understanding of this hot, dense, and intriguing planet.
