Refracturing telescopes developed in the Netherlands at the beginning of the 17th century with glass lens were the first known practical telescopes. They have been used both for terrestrial and astronomical purposes. A telescope is an optical instrument that uses telescopes, circular mirrors, or a mixture to track distant objects, or instruments, utilized through emissions, absorption, or reflections of electromagnetic radiation to observe distant objects.
On the other hand, the cleanup of the Arecibo Observatory’s collapsed radio telescope may use between $30 million to $50 million. The accident took place less than 14 days after the NSF determined that the building is too unsafe to rebuild and that it is beginning to schedule a phased demolition. It was left to purify the wreckage instead. In addition to the bill of appropriation approved in December for the fiscal year 2021, the NSF sent a seven-page report on March 5 to Congress.
The proposal requested to report in 60 days on the reason for the collapse and potential proposals for the location of the 305-meter radio telescope. The paper summed up in great detail what the telescope in August and November 2020 had already reported, so the department decided that the historic telescope should be managed to destroy the telescope. However, before the work started, the observation platform over the disk broke loose, crashing into the plates from one of the three towers that supported it.
The collapse is under investigation and, there are very some additional facts in the study to Congress. At the end of this financial year in September, initial reports of two engineering companies working on the inquiry are under prediction and, a final analysis is in December. NSF also sought “an accelerated, self-represented collapse review” from the National Academies but did not include the work plan. At least one plan to build a new radio astronomy laboratory there, supported by the Arecibo Observatory itself.
As explained in the white paper released last month, the Next Generation Arecibo Telescope will replace the only 305m dial with a narrowly packed set of smaller, between 9 and 15 m wide dishes with a diameter equal to 300m. The dishes are on the site on a “plywood, platform-like frame.” The white paper provided the new telescope with an estimated cost of about $450 million. NASA’s Planetary Defense Coordinating Office Head Lindley Johnson said that what they can do with the upcoming planetary radar is discussed. He also added that discussions are starting but, no concrete proposals have been presented.
