Robotic exploration of space is fascinating, complex, and quite important to our understanding of the universe. Join us as we speak to Chris Impey astronomer and author of "Dreams of Other Worlds: The Amazing Story of Unmanned Space Exploration" and Nick Schneider, planetary atmospheric scientist a member of the NASA MAVEN Mission Science Team (Mars Atmosphere and Volatile Evolution Mission), about how scientists and engineers overcome challenges of robotic space exploration for successful data collection.
We also learn more details about the upcoming MAVEN orbiter mission to Mars, set to launch November 18, as we seek to answer, "Where did Mars' atmosphere go?" SA blogger Joanne Manaster hosts this hangout.
