Princeton scientists restore Cold War-era satellite as teaching tool

Two Princeton University scientists set out four years ago to restore a Cold War-era radio satellite near the Jersey Shore that had become immobilized by rust, infested by wasps and enmeshed in weeds. Now, the fully functional satellite — which can be operated from Princeton's Jadwin Hall — is open to Princeton students, amateur radio enthusiasts and the public as it sweeps the skies for signals from orbiting satellites and astrophysical objects such as dying stars.
