Tatel radio telescope,National Radio Astronomy Observatory (NRAO),Green Bank,West Virginia,USA. Also called the 85-1,this 85-foot (26-metre) telescope was built at NRAO in 1958,the first of three of a similar design. The 85-1 was used for much of the early radio astronomy that took place at NRAO,but eventually it was superseded by larger models and was made part of a 3-element interferometer in 1964. Named for US physicist Howard Edwin Tatel (1913-1957),it was used by Frank Drake in 1960 when carrying out the first SETI (Search for Extra-Terrestrial Intelligence) work,then known as Project Ozma |
