Gordon Telescope is an opportunity to reflect on </span></div><div class="" style="overflow-wrap: break-word;"><span class="" style="font-size: 14px;">the history </span><span class="" style="font-size: 14px;">of the telescope itself, its amazing scientific achievements and the people who made</span><span class="" style="font-size: 14px;"> </span><span class="" style="font-size: 14px;">it all possible. </span></div><div class="" style="overflow-wrap: break-word;"><span class="" style="font-size: 14px;">In May 1958 William </span><span class="" style="font-size: 14px;">(Bill) Gordon gave a seminar in the School of Electrical Engineering at Cornell University </span></div><div class="" style="overflow-wrap: break-word;"><span class="" style="font-size: 14px;">in which he outlined the specifications of an antenna and radar system that would</span><span class="" style="font-size: 14px;"> </span><span class="" style="font-size: 14px;">be capable of measuring the </span></div><div class="" style="overflow-wrap: break-word;"><span class="" style="font-size: 14px;">electron distribution with height and other properties of the Earth's ionosphere. He also pointed out that the radar </span></div><div class="" style="overflow-wrap: break-word;"><span class="" style="font-size: 14px;">system would be capable of studies of the Sun and nearby</span><span class="" style="font-size: 14px;"> </span><span class="" style="font-size: 14px;">planets and that the antenna would also contribute </span></div><div class="" style="overflow-wrap: break-word;"><span class="" style="font-size: 14px;">to the then still new field of radio astronomy. Over the next five and a bit years, Gordon and a small group of </span></div><div class="" style="overflow-wrap: break-word;"><span class="" style="font-size: 14px;">engineers and scientists turned the idea into</span><span class="" style="font-size: 14px;"> </span><span class="" style="font-size: 14px;">reality with the completion of the Arecibo telescope in November </span></div><div class="" style="overflow-wrap: break-word;"><span class="" style="font-size: 14px;">1963. The talk will cover the telescope design and construction, some early science successes, the first upgrade </span></div><div class="" style="overflow-wrap: break-word;"><span class="" style="font-size: 14px;">of the telescope in the early</span><span class="" style="font-size: 14px;"> </span><span class="" style="font-size: 14px;">1970s, some of the science that this allowed, the second "Gregorian" upgrade in the </span></div><div class="" style="overflow-wrap: break-word;"><span class="" style="font-size: 14px;">1990s and, again, some of the resulting achievements. A large number of talented and dedicated scientists, </span></div><div class="" style="overflow-wrap: break-word;"><span class="" style="font-size: 14px;">engineers and,</span><span class="" style="font-size: 14px;"> </span><span class="" style="font-size: 14px;">yes, administrators contributed to the construction of the telescope, to the multiple telescope </span></div><div class="" style="overflow-wrap: break-word;"><span class="" style="font-size: 14px;">and instrument upgrades and to the success of the scientific programs. </span></div><div class="" style="overflow-wrap: break-word;"></div><div class="gmail_quote" style="font-size: 12px;"><span class="" style="font-size: 14px;"><span class="Apple-tab-span" style="white-space: pre;"> </span></span></div></div></span></div><div class="gmail_quote"><br class=""></div><div class="gmail_quote"><div style="overflow-wrap: break-word;" class=""><span style="font-size: 14px;" class=""><br class=""><div style="margin: 0in;
