Green Bank’s 42-foot portable telescope

Through 1976, this 42-foot portable radio telescope served as the fourth, remote member of the Green Bank Interferometer (GBI), the testbed for the Very Large Array (VLA). The 42-foot’s trailer integrated the telescope’s donut-shaped drive and a small control room, and during moves, it carried the disassembled dish as stacked panels. This photo was taken in 1967, when the telescope was assembled and tested in Green Bank.

The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.
	Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.
