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. The intent of this volume is to present a history of NASA’s “other” network, the one established and run by the Goddard Space Flight Center (GSFC). The Spaceflight Tracking and Data Network, or STDN, was—in its various incarnations throughout the years—the network that tracked the first artificial satellites around Earth. It tracked Apollo astronauts to the Moon and back. Today, a network based in space called the Space Network, along with a much reduced Ground Network, work together to support the United States and international partners in all near-Earth space communications and space- flight activities. The history of the STDN is not unlike a microcosm of the history of NASA itself. It spans 50 years. It has seen its share of triumphs and tragedies, and it is playing a major role in setting the pace for space exploration in the twenty-first century. When considering sources for this history, the author searched for scholarly works that have been published on the subject of NASA’s STDN. x “Read You Loud and Clear!” There has been some coordinated effort to document NASA’s human space- flight and near-Earth communications networks throughout the years. Starting in the late 1960s, the GSFC saw the need to begin documenting this history. From that start, most of the literature on the subject has been independently commissioned reports sponsored by the Center itself. The seminal work was by William R. Corliss in 1969 called History of the Goddard Networks. Corliss updated it five years later, expanding the sub- ject to the end of the Apollo program. These initial works were relatively general, based primarily on secondary research—assimilation of information put out by the GSFC in the form of information pamphlets, brochures and public affairs news releases. NASA historian Alfred Rosenthal drafted, in 1983, an unpub- lished work titled Vital Links: The First 25 Years of NASA’s Space Tracking, Communications and Data Acquisition 1958–1983. Vital Links was a new work on the subject, taking the timeline up through the early part of the Space Shuttle program. A key part of Rosenthal’s work was his interview of some 20 people whom he identified as principals on the subject. These were not formal oral histories but rather, topic-specific statements made by people who were major contributors on the STDN over the years. The interviews were done in 1982 and 1983 but never published. Many of these people are now deceased. The author drew heavily on these interviews and many of the quotes are used throughout this book. The draft of Vital Links was turned over to the NASA History Division where it is archived. It was a primary reference for this work. In 1992, GSFC published the Contractor Report Keeping Track: A History of the GSFC Tracking and Data Acquisition Networks 1957 to 1991. It was edited by Kathleen M. Mogan and Frank P. Mintz. The report listed them as editors rather than coauthors because Keeping Track was, for the most part, edited together from Corliss’s 1974 and Rosenthal’s 1983 works. A final chapter was added which provided a very brief overview of the STDN in the 1980s. Mogan and Mintz included excerpts from about half of Rosenthal’s interviews at the end of the report in a section called “Personal Views.” They, in addition, conduct half a dozen interviews with key network personnel who were at Goddard in 1990.
