The collapsing Arecibo Observatory is beyond repair

Context: The telescope's most recent problems began in August when a large cable unexpectedly snapped. As engineers and operators were working to find a way to secure the unstable telescope, another cable detached on November 6.

• According to the NSF, the repairs required to stabilize the telescope are too dangerous for workers to execute, forcing the foundation to decommission the telescope.
• "This decision is intended to preserve life and safety of people, and prevent the loss of the entire Arecibo Observatory, including the visitor Education Center in the event of an unexpected and uncontrolled collapse," the NSF's Sean Jones said during a press conference Thursday.
• "The decommissioning is only intended to affect the 305-meter telescope, not the rest of the observatory," Jones added.

What's next: The NSF is now developing a plan for how to demolish the telescope before it collapses.

• Areas that would be in danger due to an unexpected collapse have been evacuated and the NSF is working to find a way to keep other scientific instruments at the observatory safe during the decommissioning process.
