Another Cable Just Broke at The Iconic Arecibo Telescope, And Scientists Are Worried

 For the second time in barely a matter of months, a cable accident has occurred at the Arecibo Observatory in Puerto Rico, causing yet more damage to 1 of the world's largest and most powerful radio telescopes.

In August, astronomers and science-lovers alike were aghast to work out an enormous hole ripped through the facility's massive reflector dish, resulting from a broken auxiliary cable that fell and smashed into the structure, leaving an unpleasant gash measuring 30 metres (100 feet) long.

In the months since, engineers and workers at the observatory are making preparations for a posh repair job, with work initially scheduled to start in the week. Unfortunately, a second cable failure happening on Friday evening standard time has now complicated true further.

"This is under no circumstances what we wanted to determine, but the important thing is that nobody got hurt," says director of the observatory Francisco Cordova.

"We are thoughtful in our evaluation and prioritised safety in planning for repairs that were speculated to begin Tuesday. Now, this."

According to the University of Central Florida (UCF), which operates the Arecibo Observatory on behalf of the National Science Foundation, the second cable incident appears up-to-date some regard to the primary.

Both cables were connected to the identical support tower, and it's possible the second break was triggered by additional strain after the primary failure.

Observers at the power had been monitoring all the cables since the accident in August and had noted wires breaking on the cable that snapped last week, presumably because of fraying from the additional load. Unfortunately, before any remedial stop-guards may well be put in situ, the second cable also gave way, falling onto the dish, causing additional damage thereto, and also damaging nearby cables.

Working in conjunction with engineers brought in to assess matters, UCF is expediting the repair plan underway, with a view to reducing the stress on remaining cables as quickly as possible. Two new cables are already on their thanks to the observatory, and therefore the team will continue evaluating the structure while they expect the parts to arrive.

"There is way uncertainty until we will stabilise the structure," Cordova says. "It has our full attention. We are evaluating true with our experts and hope to possess more to share soon."

What makes the full repair and fortification project even tougher is Arecibo's age: the historic facility was inbuilt the 1960s, and held the title of the world's largest single-aperture astronomical telescope for over a half-century – until it absolutely was superseded by China's even more humongous Five hundred metre Aperture Spherical Telescope (FAST), which began its testing introduces 2016 and achieved full operational status in January.

During its long-running service, the Arecibo facility has notched up dozens of astronomical milestones, observing and recording new scientific measurements of distant exoplanets, asteroids, pulsars, radio emissions, and molecules in far-flung galaxies.

The observatory has also been at the forefront of the seek for Extra-Terrestrial Intelligence (SETI) and was the transmitter of the Arecibo message, a pioneering attempt in 1974 to broadcast an interstellar radio emission.

It may are eclipsed by FAST in terms of its size, but the Arecibo Observatory nonetheless is anticipated to own decades of discoveries left in it, but providing its serious and seemingly mounting structural issues are often fixed.

"This isn't good, but we remain committed to getting the ability back online," Cordova says. "It's just too important of a tool for the advancement of science."

That's certainly true, except for an ageing facility that's been operational since before humanity visited the Moon, it's hard to grasp evidently just how serious the damage is, and the way fortifiable or repairable the structure will ultimately be, in addition to if other accidents happen within the short term.

Here's hoping for a positive outcome, which emergency measures can stabilise this pillar of 20th-century astronomy. But even before these recent cable breakages, the observatory was still receiving repairs for damage caused by Hurricane Maria, which slammed into Puerto Rico in 2017.

"It's not a reasonably picture," radio astronomer Joanna Rankin from the University of Vermont told Science. "This is damn serious."
