On this episode of Talking Space, we take an in-depth look at the issue with the coolant pump aboard the International Space Station, the first spacewalk to repair it, and its affect on the Orbital Science launch that was scheduled for earlier this month. We then talk about ESA's Gaia spacecraft, which plans to create an in-depth map of our Milky Way galaxy. We then talk about China's successful landing of its rover on the moon, about a publicity snafu, and how it has connections going all the way back to Apollo 11 in 1969. Lastly, we address a disgruntled listener letter which is in favor of cutting planetary science, and we give our reasons why we think NASA and planetary science should still be, and is, alive and kicking.
