"Read You Loud and Clear!"; The Story of NASA's Spaceflight Tracking and Data Network

Much of what has been written on the topic of the National Aeronautics and Space Administration's (NASA) tracking and data networks has been on the Jet Propulsion Laboratory's Deep Space Network, the DSN. This is perhaps understandable as the DSN has played and continues to play a central role in many of America's most high-profile exploration missions. These have included the early Pioneer probes, the Mariner missions of the 1960s and 1970s, Viking and Voyager, and most recently, Galileo, Cassini- Huygens, and the new generation of Mars explorers that will prepare the way for eventual human voyages to the Red Planet.
