Replay: Project Vanguard


Vanguard team prepares satellite for lauch (1958)

Dr. Angelina Callahan talks about the Naval Research Laboratory’s Vanguard Project. While the launch of Vanguard 1 in 1958 was part of the Cold War “Space Race,” it also represented something more: a scientific platform for understanding the space environment as well as a test vehicle that would provide data for satellites of the future. Vanguard 1 is still flying. At 60 years, it is the oldest artificial satellite in space.

Callahan is the Naval Research Laboratory Historian. She is also a co-author (with John Krige and Ashok Mahara) of NASA in the World: Fifty Years of International Collaboration in Space. Her work has also been featured in NASA Spaceflight: A History of Innovation, the Navy War College Review, Seapower Magazine, and Federal News Radio.
