Talking to spacecraft
Hear about the state of the art from the program manager of NASA's Deep Space Network and the Spitzer Space Telescope's mission manager.
"Inside NASA's Deep Space Network" gave me an opportunity to delve into an aspect of space exploration I had always wondered about. We tend to focus on the results — the fabulous Cassini images from Saturn, Voyager 1's "taste" of plasma in the far solar system — rather than the process of acquiring them. But if you can't receive the data, there's little point in launching pricey space probes.
