A second cable break on 7 November tore through Arecibo's dish panels and brought the suspended instrument platform to the verge of collapse.

The Arecibo telescope’s long and productive life has come to an end. The National Science Foundation (NSF) announced today it will decommission the iconic radio telescope in Puerto Rico following two cable breaks in recent months that have brought the structure to near collapse. The 57-year-old observatory, a survivor of numerous hurricanes and earthquakes, is now in such a fragile state that attempting repairs would put staff and workers in danger. “This decision was not an easy one to make,” Sean Jones, NSF’s assistant director for mathematical and physical sciences, said at a news briefing today. “We understand how much Arecibo means to [the research] community and to Puerto Rico.”
