The Non-GBT Telescopes

There are many unused Radio Telescopes at the Green Bank site, most of them in relatively good working order, if only someone could put them to good use. They are, however, slowing fading into the sunset, so to speak, from disuse.

Poor lonely telescope. The Pluto marker is the last of ten proportionately spaced markers, starting with the Sun near the entrance of the Green Bank site. The first night I was there, I met an employee who had just jogged from the Sun to Pluto and back. He estimated he had traveled the distance at approximately seven times the speed of light, based on those markers!

A couple more old timers.

Yet another grandfather telescope, a 140 feet diameter dish.

The 140 Footer compared to the 300 foot GBT, most of a mile away.

The Forty Footer, the 140 Footer, and 300 foot GBT, each having approximately the same apparent size from this perspective.

This one was built by the Navy, to assist in its efforts to accurately track their submarines. The advent of Global Position Satellites (GPS) made it obsolete.
