The Arecibo telescope was built in 1963 as the world’s largest radio telescope located in Puerto Rico. It has contributed historical importance in science, planetary defense, and for Puerto Rico. The US National Science Foundation (NSF) has decided to permanently close the site as the cable was damaged beyond repair according to engineers. The first cable smashed panels at the edge of the dish, but the second tore huge gashes in a central portion of it. NSF plans to safely lower the platform down in a controlled fashion and there is no estimate yet on the cost of decommissioning the telescope.
