Arecibo Observatory telescope cleanup could cost up to $50 million, NSF reports

Cleaning up the collapsed radio telescope at the iconic Arecibo Observatory in Puerto Rico could cost between $30 million and $50 million, according to the National Science Foundation (NSF).

The cost estimate, revealed Friday (March 5), is laid out in an NSF report required by Congress after the giant radio telescope’s hanging science platform crashed down through the 1,000-foot (305 meters) dish on Dec. 1. Two supporting cables had snapped on the telescope in the months before the collapse.
