Investigating the Structural Failures Behind Arecibo's Collapse
TL;DR
The collapse of the Arecibo Observatory's telescope in 2020 is attributed to zinc creep in cable sockets, potentially accelerated by electroplasticity due to electromagnetic radiation, according to a National Academies report. The report suggests that the unique electromagnetic environment of the telescope may have hastened the failure, despite a safety factor above two. The NSF plans to replace the telescope with a science education center and is considering the report's recommendations for future projects.
