Yet with nearly two decades since the last U.S. mission there, our sister planet has received little attention in recent years. 'Return to Venus' provides a look back at the history of Venus exploration, how human perceptions of the planet have changed through time, and inspires us to think about what secrets we have yet to reveal from our inhospitable and enigmatic neighbor.    Dug out of the NASA archives is this history of Venus exploration, a history that ended over a decade ago and leaves many questions still today.
