All About Decommissioning Arecibo Telescope
The world's largest
single-aperture telescope in Arecibo, Puerto Rico, is on the brink of collapse.
The lifespan of this telescope is about to get over. The dismantling process
will start soon by NSF. Arecibo Telescope has served radio astronomers for the last
57 years. The decision to dismantle the telescope came in August 2020, when one
of the support cables snapped.
About Arecibo Telescope
When built in the
early 1960s, it worked towards the study of the ionosphere. But, then the
scientists used it as an all-radio observatory. Arecibo Telescope finds its
application in radar astronomy, radio astronomy, and atmospheric science. It
consists of four radar transmitters of 20 TW at 2380 MHz. Puerto Rico's
location gives an ideal advantage to the Arecibo Telescope. It helps to view
planets in the Solar System over the Northern half of their orbit. The
University of Central Florida, Yang Enterprises, and UMET operate the
telescope. The AT is a source of pride for the country and the global
scientific community.
The AT has a glorious
history in terms of Space Explorations. Some of them are:
●
First concrete
evidence of Neutron Star
●
Aleksander Wolszczan
and Dale Frail detected exoplanets in January 1992
●
Detection of
prebiotic molecules methenamine and hydrogen cyanide from starburst galaxy Arp
2020.
●
To sense intelligent
life from other cosmos - SETI & METI Project
●
Track near-Earth
asteroids
Recent natural
disasters impacted the 900-tonne structure suspended 150m above the dish. The
major one was Hurricane Maria in 2017. Another Tropical storm Isaias, struck in
August 2020. One of the platform-support cables broke. It damaged the
telescope, including a 100 ft (30 m) gash in the reflector dish. The dent also
includes damage to the Gregorian dome. NSF ordered the replacement of the cable
broken. But, before being replaced, in November 2020, another cable wire
snapped. As a result, NSF decided to decommission the entire Arecibo Telescope
Program. But, NSF also declared that the rest of the observatory would remain
open.
Many challenges are
lying ahead related to this dismantling process. The scientists have not laid
the plan to deconstruct the structure with safety. Due to the severe risk near
the area, scientists were unable to evaluate the current status. Also, to run
the scientific operations, UCF and NSF should seek other telescopes with
similar niches. Hence, it is essential to assess the situation at a faster
pace. Also, the adoption of alternatives will bolster Space research.
