SAN JUAN, Puerto Rico (AP) — The National Science Foundation has announced it will not rebuild a renowned radio telescope in Puerto Rico, which was one of the world’s largest until it collapsed nearly two years ago. Instead, the agency issued a solicitation Thursday for the creation of a $5 million education center at the site that would promote programs and partnerships related to science, technology, engineering and math. The solicitation does not include operational support for current infrastructure at the site that is still in use, including a 12-meter radio telescope or the Lidar facility, which is used to study the upper atmosphere and ionosphere to analyze cloud cover and precipitation data.
