After a test run of 250 stars at the Arecibo Observatory in Puerto Rico that turned up nothing, Horowitz brought Suitcase SETI back to Harvard, and in 1983, Project Sentinel was launched. Project Sentinel utilized an 84-foot steerable radio telescope equipped with a renovated Suitcase SETI, located at the Oak Ridge Observatory in Harvard, Mass...

According to the Harvard Search for Extraterrestrial Intelligence (SETI) Web page (http://mc.harvard.edu/seti/), the search first began in 1978 with scientists listening to signals transmitted from a 1,000-foot dish in Arecibo, Puerto Rico...

...SOHO the same way flight controllers look for commercial airliners: with radar? Realizing that extremely powerful radar would be needed to bounce a signal off so distant a target, he called on Donald Campbell, the chief scientist at the world's largest radiotelescope, the 1,000-ft. dish at Arecibo, Puerto Rico. Campbell agreed to try, although he estimated that the power of the returned signal would be about a billionth of a watt...

...July 23, Arecibo directed a powerful high-frequency radio beam toward the site SOHO should have been, a million miles away orbiting the sun. Ten seconds later, NASA's 230-ft. radiotelescope at Goldstone, Calif., began picking up its faint radar profile, barely perceptible against the background noise of space...

ITHACA, New York: Visions of the moon as a giant refueling station for future space missions evaporated as a team of scientists said that, contrary to a December report, there's no evidence of ice there. Using new radar images from Puerto Rico's Arecibo Observatory, astronomers from Cornell University determined that what the Defense Department's Clementine space probe showed as waves of frozen water is instead merely the rough surfaces of impact craters. If true, the news could mean a setback for space explorers hoping to use the ice to produce hydrogen and oxygen, the main components...
