We have so much to learn about Venus, says JPL scientist Sue Smrekar. What we learn will help us understand our own world and Mars. Sue joins us this week to make a great case for a new Venus orbiter. The Parker Solar Probe has begun its exciting journey to “touch the Sun.” Our MaryLiz Bender talks with mission leaders before and after the launch. Bruce Betts and Mat Kaplan have two great space trivia contests to wrap up right after they take us on another What’s Up tour of the solar system and back through the history of space exploration.
