CSIRO’s Parkes Observatory turns 50 on October 31 and is celebrating with public Open Days this weekend.
The The Dish in 2000. On July 21 in 1969, along with the Honeysuckle Creek tracking station outside Canberra and NASA’s Goldstone station in California, the Dish received and relayed television signals to Mission Control at Houston.
NASA discovered that Parkes was receiving superior pictures and used this footage for the remaining 2.5 hours of the telecast. As part of the Open Days, the Apollo 11 video (recently restored by NASA) will be on sale for the first time ever at Parkes Observatory.
John Sarkissian, Telescope Operations & Science Operations at Parkes Observatory, says the Dish has also been involved in a number of scientific discoveries. In 1962, the telescope helped identify and determine the nature of the first quasar, and has found most of the 2000 known quasars.
The Dish has also been involved in mapping our Galaxy, finding other galaxies, discovering magnetic field of the Milk Way and hunting for gravity waves. “Parkes is still one of the best-performing radio telescopes in the world,” Chief of CSIRO Astronomy and Space Science Dr Phil Diamond said in the press release.
Repeated upgrades have made the telescope 10,000 times more sensitive than when it first opened. The standout new technology has been the multibeam (multipixel) receiver, which allows the telescope to see more of the sky at once, Diamond said.
To celebrate the observatory’s 50th anniversary, the Parkes Observatory will host an Open Day weekend on October 8 and 9 to showcase its history and achievements. Members of the public will be able to take a guided tour through the control room and central column of the telescope.
