U.S. National Science Foundation (NSF) Plans to Decommission Arecibo Observatory Telescope
An Anonymous Coward and pTamok write:
Following a review of engineering assessments that found damage to the Arecibo Observatory cannot be stabilized without risk to construction workers and staff at the facility, the U.S. National Science Foundation will begin plans to decommission the 305-meter telescope, which for 57 years has served as a world-class resource for radio astronomy, planetary, solar system and geospace research.
The decision comes after NSF evaluated multiple assessments by independent engineering companies that found the telescope structure is in danger of a catastrophic failure and its cables may no longer be capable of carrying the loads they were designed to support. Furthermore, several assessments stated that any attempts at repairs could put workers in potentially life-threatening danger. Even in the event of repairs going forward, engineers found that the structure would likely present long-term stability issues.
"NSF prioritizes the safety of workers, Arecibo Observatory's staff and visitors, which makes this decision necessary, although unfortunate," said NSF Director Sethuraman Panchanathan. "For nearly six decades, the Arecibo Observatory has served as a beacon for breakthrough science and what a partnership with a community can look like. While this is a profound change, we will be looking for ways to assist the scientific community and maintain that strong relationship with the people of Puerto Rico."

Arecibo Heartbreak: Iconic SETI Dish Will Be Demolished Due to Risk of 'Catastrophic' Collapse
The recent failure of two support cables at the Arecibo Observatory in Puerto Rico has destabilized the structure such that it cannot be repaired without placing construction workers at significant risk, according to officials with the National Science Foundation. As feared, the beloved 1,000-foot telescope will have to be decommissioned.
As if 2020 couldn't get any worse, we received news this morning that the giant dish at Arecibo will have to be demolished. The National Science Foundation came to this hard decision following a review of engineering assessments, which concluded that the observatory is in seriously bad shape and that it cannot be stabilized without placing workers in danger. The NSF is now planning for the controlled decommission of the dish, ending a historic 57-year run.
But there is this . . .
"I want to say this as forcefully as possible," said Ralph Gaume, the director of NSF's Division of Astronomical Sciences, at a call for reporters earlier today. "We're not closing the Arecibo Observatory."
