Giant Radio Telescope Collapses - and Rises Again


"QUANTUM SHOT" #455
link


This was a case of "Humpty Dumpty", total structural failure

A giant radio telescope at Green Bank, West Virginia, collapsed into a "twisted mess" without any visible cause, or previous warning.

There was no wind, no covert landing of malicious aliens - on that night of November 15th, in 1988. During its normal operation (while studying gravitational lenses and distant galaxies), the scientific colossus suddenly folded up in a tangled heap around the control building... amazingly, according to this info, no scientist inside of it was hurt.

Before & after collapse:

One possible cause for this collapse is believed to be the sudden failure of a large gusset plate in the box girder assembly - a key structural element in antenna's support. The big science was thwarted (again) by a single piece of metal... as in a few other unfortunate cases we can recollect.

But honestly, we all know what REALLY happened:




New radio telescope dwarfs the old one!

The telescope was rebuilt in 2000; it is now bigger, better, and (obviously) structurally safer than its predecessor. Still, human engineering ends up pushed to the limit when it comes to such titanic and intricate structures...

At least the largest telescope dish is safely cradled between some forested hills. I'm speaking, of course, about "the largest single dish in the world" - Arecibo Observatory (at 306 meters):

Well, the newly rebuilt in place of the collapsed telescope (and no less impressive) Robert C. Byrd Green Bank Telescope is considered The Largest Steerable Single Dish in the World (at 100 by 110 meters) -

See miniature people below? This is truly a colossal structure:

Contrary to all logic, this giant Russian telescope still stands strong!

Other telescopes can collapse, but this one keeps standing. Even though it's totally rusted and has been abandoned for years... Having a rainbow snuggle up to its dish apparently helps with a structural blessing:




See more images on this page. We also wrote once about another abandoned Ionospheric Research Staion. Time to bring these facilities back to life... especially since they refuse to come to total ruin and continue to haunt the landscape.


Strangest Shape for a Radio Telescope

This is "The Horn Antenna" at Bell Labs, Holmdel, New Jersey. It's where the cosmic microwave background radiation was discovered in 1965. Apparently such design worked really well for research purposes... truly looks like one giant ear, tuned to the Universe:

Maybe the "hostile aliens" are too freaked by its appearance to zap it... maybe they're consolidating their forces to strike against CERN's collider. Maybe these aliens are listening to all I type. I should stop now...

Joining the long list of things in WV named "The Robert Byrd..."
What a boondoggle and waste of taxpayer dollars. But I bet it paid for a lot of oxycontin.

What! No mentioned of Arthur/Goonhilly or Jodrell Bank?

The "horn antenna" is actually not very exotic. You have probably ignored many of these located on point-to-point microwave towers located across the world. Even if you paid attention, you might not have recognized them, because horn antennas are usually oriented upright rather than "lying down," and a weather-resistant covering covers the aperture. For example, look at this photo:

No its not, It doesnt even get close, Jodrell Bank is the third largest steerable radio telescope and thats 77m, The one posted in the link is 50m.

As for Radio Telescopes in general, Well Im sure we all know Aricebo is the biggest single dish by far.

I went to see Jodrell Bank not long ago, Im only 50 miles from it, If you live near one of these dishes they are well worth the visit, Very impressive to see them moving about, And the size of them is incredible.

The Russian telescope is Kalyazin RT-64 (64 meter), and judging by the fact it's in a different orientation in every picture online, I daresay it's not been "abandoned for years". Not well maintained, perhaps.

You might be interested in my online book about NRAO, where I talk about the telescope and the history of the place. You can read it here.
