Arecibo radio telescope kaput

'The National Science Foundation (NSF) will decommission Arecibo Observatory's massive radio dish after damage has made the facility too dangerous to repair, the agency announced today (Nov. 19).

The announcement came as scientists awaited a verdict about the fate of the iconic observatory after damage to the complex cabling supporting a 900-ton science platform suspended over the dish. In August, a cable slipped out of its socket, but engineers evaluating the situation deemed it stable; earlier this month, a second cable unexpectedly snapped, leaving Arecibo's fate much more perilous. After considering three separate engineering reports, the NSF, which owns the property, has decided the facility is unstable enough that there is no way to repair the damage that does not put personnel at undue risk.'

fuxsake...

That's a real shame. At least they intend retaining some aspect of the facilities.

Many sounds in the linked album were from the Deep Space network, including the Arecibo telescope.

Have they tried switching it off & back on again?

"Well, it's a vast lash up of 900 tons of kit and platform held 450 feet aloft by a reduced number of (and very dodgey) cables some of which are slipping in their stays. Looks OK from a distance but whole thing is 57 years old, in general shit order after years of penny pinching and could let go at any time."

"Yes but can you fix it and stay within budget?"

I have been in so many meetings like that.
 
Local skateboarders will be happy.
 
Interesting bit on YouTubey about it...

I thought his accent had a bit of Brit abroad about it. Simon Holland - IMDb
