1156-741: The Neilson Report , which recommended across-the-board financial cuts to all federal government organizations, including the NRC. This led to staff and program cutbacks. By 1985, however, two entities emerged from the National Research Council: the Social Science and Humanities Research Council (see SSHRC Act) and the Natural Science and Engineering Research Council (See NSERC Act). The emergence of these Councils, for all material reasons, took over funding from

1224-474: The 150 ft (46 m) telescope started in the spring of 1964. The concrete base weighed 300 tons, the steel dish and its rotating mount another 900 tons. An equatorial mount in the base, only five feet high, positioned the instrument. The telescope was designed to operate at higher frequencies than existing instruments, requiring much of it to be constructed of flat plates instead of an open mesh in order to accurately focus these signals. The surface

1292-569: The ARO became less useful. After planning to resurface it so that it could operate at wavelengths as small as 3 mm, the NRC decided to close the ARO in 1987 and purchase a 25% share in the new James Clerk Maxwell Telescope , which would include a radio telescope that could operate at 0.3 to 2 mm. In 1988 the NRC invited the operators of the Hay River Radio Observatory in the Northwest Territories ,
