Project Ozma hardware

Project Ozma Hardware

This equipment was installed in the control room of the 85-foot Howard E. Tatel telescope in Green Bank in 1960. Dr. Frank Drake used it to perform the world’s first search for extraterrestrial intelligence. He called the search Project Ozma, after the fictional queen of Oz. For two months, Drake and his team observed the stars Tau Ceti and Epsilon Eridani, two nearby, Sun-like stars. No signs of ETI were detected.

Moving House in Green Bank

Several farms were purchased in Green Bank to form the NRAO’s first observatory. Instead of being demolished, the houses that were in the way of telescope and building placement were moved to new locations around town and got new owners.
