Génesis Ferrer had dreamed of working in the Arecibo Observatory ever since she first met some of its astrophysicists during a high school trip in Puerto Rico.
After hearing them use terms such as “radiation” and “emission,” Ferrer, 21, said she “just fell in love with the entire idea of being able to understand things so far away.” Like many scientists in the U.S. territory, Ferrer can trace back her interest in astrophysics, biophysics and space to that school trip.
The fourth-year physics student from the University of Puerto Rico, Río Piedras campus, had recently earned a fellowship from the Puerto Rico NASA Space Consortium to study emissions from red dwarf stars using the giant radio telescope in Arecibo. Because of coronavirus restrictions, Ferrer has been accessing the data she needs from the Arecibo Observatory remotely, hoping she would soon be able to finish her investigation in the place where it all started.
Those hopes faded away Tuesday morning when the Arecibo Observatory collapsed. The telescope’s 900-ton receiver platform and the Gregorian dome — a structure as tall as a four-story building that houses secondary reflectors — fell onto the northern portion of the vast reflector dish more than 400 feet below after the main cables holding up the structures broke overnight.
“I was very sad, very disappointed,” Ferrer told NBC News. “I worked so hard to finally get accepted to work in the Arecibo Observatory. And now that I got accepted, I can’t work in it. I felt very sad, not only individually, but I also saw it as a very sad thing for Puerto Rico and the science in Puerto Rico.”
The Arecibo Observatory was the largest radio telescope in the world and a point of pride for Puerto Ricans, whether they were in science or not. About 90,000 islanders and tourists visited the observatory every year, a boon to the region.
During its almost 57 years in operation, the observatory built with money from the U.S. Department of Defense has been at the forefront of space research — and a crucial training ground for space science students.
In August, the observatory started crumbling after an auxiliary cable snapped, causing damage to the telescope’s dish and the receiver platform that hung above it, according to the U.S. National Science Foundation, the federal agency that owns the observatory. In an attempt to prevent “an uncontrolled collapse” in order to “safely preserve other parts of the observatory that could be damaged or destroyed,” the agency said it began its plan to decommission the telescope in mid-November.
“The NSF was taking a long time to do this because they have a series of protocols they have to follow,” said Abel Méndez, director of the Planetary Habitability Laboratory at the University of Puerto Rico, Arecibo campus, and a planetary astrobiologist. “We thought they had an emergency plan that could speed things up.”
But the cables failed before the agency was able to preserve the telescope.
