Iconic Arecibo Observatory telescope collapses

A huge radio telescope in Puerto Rico has collapsed after decades of astronomical discoveries.

 

The US National Science Foundation (NSF) said the telescope's 900-ton instrument platform fell onto a reflector dish some 450ft (137m) below.

 

It came just weeks after officials announced that the telescope would be dismantled amid safety fears, following damage to its support system.

 

The Arecibo Observatory telescope was one of the largest in the world.

 

It was a key scientific resource for radio astronomers for 57 years, and was also made famous as the backdrop for a scene in the James Bond film GoldenEye and other Hollywood films.

 

The NSF said there had been no reports of injuries following the collapse.

Really sad day :(

 

Last I heard they were going to decommission Arecibo being the risk to the construction workers was too great to repair the telescope after the second cable snapped, which was I sad when that was announced.

Might be a slight blessing it fell on its own considering they were going to dismantle it anyway (after the cables started snapping this year).  Believe I read that the learning center received damage from the falling cables ... but no injuries.  There is still an operational radio telescope and a Lidar facility there ... hopefully this doesn't cost too many jobs.

 

Sucks for science ... sucks that years of inadequate funding/maintenance led to this...

I'd love to see them rebuild it better, but I suspect that won't be happening.

I want to see security cam footage of it collapsing.

NAsA is exploring their options.

 

In terms of resolution Goldstone has an edge over Arecibo, but the latter's use as a radar was more powerful.

 

One option being explored is a collaboration with the US Space Force, which wants to build a large system for tracking objects and debris in cis-lunar space; CHIPS (Cislunar HIghway Patrol System), taking on the role of a space  "Coast Guard." Also small space stations in cis-lunar orbits, optionally manned for research or as an emergency refuge, etc.

 

The US Air Force Research Laboratory is also interested in cis-lunar space.

Scott Manley's published an analysis of what exactly happened, in slowmo...
