A coalition of scientists from Puerto Rico and the diaspora has launched a call asking the United States government to take into account the opinions of the Puerto Rican scientific community when planning and designing the replacement of the Arecibo Observatory and to make a real financial commitment for its construction. In a letter, the group elaborates on the scientific and educational value that the Arecibo Observatory fulfilled for many years. Among the requests, the group demands that the next project reflect the latest technological advances, preserves and enhances the educational mission that was developed in Arecibo, and has sufficient scientific personnel.
