The main cable supporting Arsibo observers was broken last Friday at 7:39 a.m. in Puerto Rico.
On August 10, 2020, this main cable did not come out of the socket. It broke and fell on the reflective food below, causing further damage to the plate and nearby cables. Both cables are connected to a support tower. No one was injured, and the engineers are already working to determine the best way to stabilize the structure.
Carefully set up a safety zone around the dish and only staff who are needed to respond to the damage will be allowed on site.
Authorities have not determined why the main cable was cut, but they estimate that the remaining cables will be connected to the additional load since August. Since then, the monitoring team has been closely monitoring all cables and platforms as part of the facility’s security and temporary emergency maintenance plans. Observers saw and tracked broken wires on the failed main cable on Friday. A team of engineers was expected to begin temporary emergency repairs in connection with the August incident.
“This is not something we want to see for sure, but the main thing is that no one is hurt,” said observer Francisco Cordova. We have considered the review and planned to make repairs that are expected to begin on Tuesday. Now this. There is a lot of certainty as long as we can stabilize the structure. He has our full attention. We are reviewing the situation with our experts and we hope we have more to share soon. ”
The University of Central Florida, WSP, Thornton Tomasetti and Wiss, Janney, Elstner Associates Inc. To develop a strategy to address the new crisis. In connection with the first cable, the UCF protected these companies in September. The UCF is also the owner of the NSF, which owns the institution. Announced NASA. Drones and cameras are also used to monitor the structure.
To temporarily alleviate the additional load being distributed between the remaining cables, the team believes it can reduce the tension in the existing cables on the tower and install steel reinforcements. Experts are working to get the job done as quickly as possible. The team is trying to speed up the arrival of two new ropes that were previously ordered. That is the current plan, which is expected to be reviewed in the next few days.
The USFF is awaiting additional funding from the NFF to make temporary repairs related to the initial rest. There are currently no cost estimates for new repairs.
Since mid-August, engineers have been working to determine the cause of the initial failure and to create temporary and long-term maintenance plans. Because there is no clear reason for a break, the complexities of this large and unique structure built in the 1960s and, above all, the need to prioritize safety, have taken some time to plan temporary emergency repairs. The first repairs were scheduled to begin this week.
“This is not good, but we are committed to bringing the institution back online,” Cordova said. It is an important tool for the advancement of science.
Arsibo observers are one of the most powerful telescopes on the planet. Its instruments are used by scientists around the world to conduct research on atmospheric science, planetary science, radio astronomy, and radar astronomy. Aresibo is also the team that manages the planet’s radar project supported by NASA’s Earth-Earth Object Monitoring Program at the NASA Planet Prevention Coordinating Office.
Although the institute has suspended most of its operations since August, the researchers continue to use the data previously collected by Arsibo to further their research. Since its inception 50 years ago, the plant has withstood a number of hurricanes, tropical storms, and earthquakes. All in all, the institute has continued to make significant contributions to space exploration in the area Gravity wave, Steroid behavior, planetary navigation and more.
