Completed at the US Naval research laboratory in 1954, the 10 foot radio telescope is equipped with a solid reflector capable of detecting extremely short wavelengths of radiation from space. In 1961, this instrument measured energy from Venus at a record short wavelength of 4.3 millimeters. The 10 foot radio telescope has also been used to study the composition of the surface of the moon.
