The Nationwide Science Basis introduced final week that it received’t rebuild or exchange the enduring Arecibo Observatory in Puerto Rico, which collapsed in 2020. As a substitute, the NSF says they’ve solicited requires proposals to construct a multidisciplinary instructional heart on the web site.
Moreover, the plans don’t seem to permit for any future science or observing from the opposite services on the Arecibo web site, because the NSF stated they won’t present any “operational assist for present scientific infrastructure, such because the 12-meter radio telescope or Lidar facility,” additionally on location.
The announcement has been met with disappointment and disbelief.

“I’m heart-broken by this resolution,” stated native Puerto Rican and planetary astronomer Edgard Rivera-Valentín, who was born in Arecibo and was impressed by the science and discoveries being made in proper of their again yard.
“Arecibo’s position in inspiring generations of Puerto Ricans centered on the truth that we had a world-class facility doing cutting-edge science in our residence,” Rivera-Valentín advised Universe Right now. “After I had the privilege of working on the observatory, as the primary Arecibeño scientist to take action, I noticed the way it continued to serve that necessary position. However it did so as a result of we have been doing nice science with the telescope. It did so as a result of scientists on the observatory could possibly be mentors and position fashions to college students. With out the telescope, with out the scientists, I don’t personally see how going to the customer heart received’t be like going to a memorial.”

The collapse of Arecibo’s radio telescope was a devastating blow to the radio astronomy group. Points started in 2017 for the practically 55-year-old telescope when Hurricane Maria tore by way of Puerto Rico, shearing off one of many 29-meter (96-foot) antennas that was suspended above the telescope’s 305-meter (1,000-foot) dish, with falling particles puncturing the dish in a number of locations. In early 2020, earthquakes briefly closing the observatory for security causes; then a succession of cable failures in the end led to the December 2020 collapse of the 900-ton instrument platform suspended above the observatory, which crashed down on the enduring telescope’s large dish. This collapse formally ended any attainable hopes of refurbishing the well-known observatory.
Since then, many have referred to as for the telescope to be rebuilt or for constructing a fair higher alternative telescope on the web site. As a substitute, the NSF desires Arecibo to function a hub for STEM training and outreach.
The NSF says that it’s following group suggestions for not planning to rebuild the Arecibo Observatory. Nevertheless, the latest Planetary Science and Astrobiology Decadal Survey famous that, “The lack of the Arecibo Observatory planetary radar vastly inhibits the power to carry out follow-up NEO (close to Earth object) characterization. Present radar infrastructure can observe solely half the asteroids as soon as observable with Arecibo.”
Rivera-Valentín, a planetary scientist whose work contains radar characterization of NEOs, stated, “I’m dismayed by the choice to not reconstruct the Arecibo telescope, particularly with out an alternate plan to switch or exceed the now misplaced capabilities of Arecibo.”

The Arecibo Observatory was accomplished in 1963 and for over 50 years (till the China’s 5-hundred-meter Aperture Spherical Telescope (FAST) was full in 2016) it was the world’s largest single-aperture telescope. It was utilized in three main areas of analysis: radio astronomy, atmospheric science, and radar astronomy. The observatory has appeared in films, tv exhibits and extra, and is listed on the US Nationwide Register of Historic Locations.
The ability has contributed to important breakthroughs in astronomy and cosmology, together with the invention of the primary binary pulsar, the first-millisecond pulsar, the primary exoplanets, together with serving to to check asteroids and planets within the Photo voltaic System. As well as, the ability has additionally performed an necessary position within the Seek for Extraterrestrial Intelligence (SETI), offering the supply information for [email protected] and the SETI Institute’s Undertaking Phoenix.
Whereas the choice to not rebuild impacts the power of scientists to check quite a few astronomical objects, this resolution may even have an effect on Puerto Ricans. The NSF famous that the observatory had grow to be “a extremely regarded a part of the group for a lot of of Puerto Rico’s residents, serving as a supply of satisfaction and native financial profit whereas additionally offering entry to coaching and employment for a lot of in the neighborhood.”
Rivera-Valentín worries that as a result of Puerto Rico doesn’t have many on-island alternatives for STEM professionals, will probably be tough to retain island-born scientists and engineers.
“It will contribute to the continuing so-called mind drain, which is seeing many individuals leaving the island for job alternatives,” Rivera-Valentín stated. “The Arecibo Observatory was capable of retain a few of that necessary STEM experience on the island by using scientists and engineers. With regard to astronomy, Puerto Rico doesn’t have many alternatives. That is greatest seen within the college system. At the same time as latest as a decade in the past, Puerto Rico didn’t supply any levels in astronomy. However due to the work the observatory scientists have executed in partaking the local people, there at the moment are Astronomy levels supplied by the College of Puerto Rico.”
With out an lively scientific facility, Rivera-Valentín sees the potential for the momentum behind these efforts being vastly hindered.
“I hope I’m fallacious,” Rivera-Valentín stated.
