UCF manages Arecibo under a cooperative agreement with Universidad Ana G. Méndez and Yang Enterprises Inc.

The Arecibo Observatory received a $2 million grant in June 2018 after Hurricanes Irma and María ripped through the island and damaged the facility in 2017. Those funds were used to make emergency repairs such as fixing the catwalk that leads to the reflectors suspended above the 305-meter dish. In addition, buildings were repaired, generators were serviced, and first responder equipment was replaced. This funding also enabled the facility to prepare for the 2019 hurricane season.

Projects from this grant include:

  • Repairing one of the suspension cables holding the primary telescope platform, ensuring long-term structural integrity of one of the main structural elements of the telescope.
  • Recalibrating the primary reflector, which will restore the observatory’s sensitivity at higher frequencies.
  • Aligning the Gregorian Reflector, improving current calibration and pointing.
  • Installing a new control system for S band radar, which is part of the microwave band of the electromagnetic spectrum.
  • Replacing the modulator on the 430 MHz transmitter, increasing consistency of power output and data quality.
  • Improving the telescope’s pointing controls and data tracking systems.

Each of these projects is essential to the work conducted at the facility, which includes research in the areas of planetary radar, astronomy and space and atmospheric sciences, administrators say. The telescope has assisted in the understanding of gravitational waves, the theory of relativity, the discovery of new planets, and other research. The instruments also play an important role in monitoring asteroids that could pose a hazard to Earth.
