Here are some videos about the planet Venus that I found on YouTube.
Return to Venus – Part 1
The is the first of a two-part video developed by NASA that discusses the exploration of Venus, starting with the Mariner 2 spacecraft.
Return to Venus – Part 2
Here’s part 2 of the Venus video, Return to Venus. In this part, NASA scientists discuss the Russian Venera landers, and NASA’s Magellan spacecraft. In the end, it wonders why NASA isn’t going to be participating in the exploration of Venus any more.
Mission to Venus
This is a concept video for a mission that NASA developed called the Revolutionary Aerospace Systems Concepts (RASC) program. It was a program to develop a conceptual design for a robotic mission to explore the surface and atmosphere of Venus.
