"The Dish" emits signals from Australia 50 years after the moonwalk



It is known as "The Dish" and rises above a nondescript paddock in rural Australia. Without them, hundreds of millions of people would never have seen all the footage of Neil Armstrong, who walked on the moon 50 years ago.

PARKES, Australia: It is known as "The Dish" and it rises above an inconspicuous paddock in rural Australia, without which hundreds of millions of people would never have seen the entire generation-defining footage of Neil Armstrong, who walked on the moon 50 years ago.

wise, 600 million people around the world held their breath while watching television. On July 20, 1969, screens were displayed on which Armstrong was waiting to get out of the Apollo 11 lunar module and enter the history books.

Back on Earth, it began as another working day for Armstrong David Cooke, Senior Reception Engineer at the Park Telescope's Park Telescope Observatory in southeastern New South Wales, about 360 miles west of Sydney.

The Parkes Observatory was one of three tracking stations, with Goldstone in California and the now defunct Honeysuckle Creek station in the Australian capital of Canberra, with the mission of beaming live images of the moonwalk into the world.

Cooke was just concerned about getting his job done right and right Make sure the signal is not lost.

In the US, the National Aeronautics and Space Administration (NASA) control room has switched the signal between the three tracking stations and received the Parkes signal eight minutes after transmission began. [19659018] Advertising

NASA found the quality of the Parkes images so superior that they kept the signal of the local observatory nicknamed "The Dish" for the remainder of the hours-long broadcast.

"It was after we finished the chase when I went down in front of the telescope and looked up and saw the moon," recalled Cooke, now 87 years old and responsible for surveillance at the Observatory.

I've noticed that this is an amazing thing, that there is one man, two men on the moon and a third too, "he said.

The Commonwealth Scientific and Industrial Research Organization (CSIRO) Parkes Radio Telescope was officially opened on October 19, 61 and with a diameter of 64 meters (210 feet) remains one of the largest single-dish telescopes for astronomy in the Southern Hemisphere.

"The Dish" is still being used by astronomers around the world [19659011] Continuous upgrades keep it up-to-date with radio astronomy – the telescope is now 10,000 times more sensitive than when it was first used.

The magical images that shone around the world in 1969 also changed the life of one six-year-old boy who saw the moon land with his classmates on the cold, wooden floor of their school room in Sydney.

"I've noticed that it really time to think about astronomy, "said John Sarkissian, now a CSIRO telescope operations scientist.

"I had no idea at that time that it was 50 years." later, I would actually work in the place where these television pictures were received, "he said
