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.
