40 FT Telescope Poster
Custom 24x36 Gloss Poster
The 40-foot telescope can only move in one direction, up and down. It relies on the Earth’s rotation to swing it underneath the space objects it observes. With a control system designed and built by NRAO staff, on February 1, 1962 the 40-foot became the world’s first fully automated telescope.
More than 1,500 students ranging from 5th graders to graduate students use the telescope to investigate the radio universe every year.
