Default Arecibo telescope to be demolished

It is sad that the Arecibo telescope will soon be demolished. I
understand that it is the right thing to do given the dangerous state in
which it is. Still, it is sad to lose such an instrument.

Remember when Alain Fournier bragged outrageously? That was Thursday:
It is sad that the Arecibo telescope will soon be demolished. I understand
that it is the right thing to do given the dangerous state in which it is.
Still, it is sad to lose such an instrument.


Yes.

It seems they cannot find a safe way to repair it, and are uncertain
about its integrity given that a cable appears to have failed at well
under its theoretical strength.

But it was built once. It could be built again.

On Friday or thereabouts, Sylvia Else declared ...

Ha ha.

Radio astronomers make for bad civil engineers appearently. It was just
a few short months ago that we were reading that new cables would be installed
in an attempt to repair the telescope. Now with an additional cable
break it has become too unstable to safely repair. But this is
deterioration over time. You can't tell me it was impossible to to spot
these issues well enough in advance to have not waited until it was too
late. So much for science in the public interest. Has it become the case
that this telescope has actually outlived its usefulness and no one was
willing to point out the emperor has no clothes? From what I can see, it
was already a wasting asset and must have been for years.

What makes you think the radio astronomers were involved in the civil
engineering assessments?

Did you read the articles? It has had difficulty with funding for
years, and the will to upgrade it or replace it has been diverted into
newer and more capable instruments.

Lo, on the 11/20/2020, David Spain did proclaim ...

a few short months ago that we were reading that new cables would be
installed in an attempt to repair the telescope. Now with an additional cable
break it has become too unstable to safely repair.


They hired three different consulting firms, and had new cables on
order. The last break was clearly at a load well below spec, which
means the other cables can't be trusted.

Please read more carefully.

Read what? I've seen no cites. Did you post something earlier I may have
missed?

Aha I did miss it, sorry:
