The Vanera landings on Venus are the craziest space events you've never heard of. Launched by the Soviet Union in 1970, Vanera 7 became the first ever probe to land on the surface of Venus. This planet is a hell zone with an atmospheric pressure nearly 90 times out of Earth and a surface level temperature of 900 degrees Fahrenheit. Yet this 1960s probe was able to survive almost half an hour before a signal was lost. I hope this remarkable achievement inspires you.
