As Earth's biggest "ear" on the Universe, the giant 305-meter radio dish at Arecibo, Puerto Rico, has played a part in groundbreaking discoveries, searches for alien civilizations and the occasional Holly¬wood movie. Now a different sort of drama is shaking up the facility, with the news that Cornell University, which has managed Arecibo since the observatory was switched on 1963, has lost its bid to continue to do so. Instead, the U.S. National Science Foundation (NSF) has offered the job--and the $41.2-million five-year contract that goes with it--to a consortium that includes SRI International, a non-profit research institute based in Menlo Park, California; the Universities Space Research Association in Washington, D.C.; and the Metropolitan University in Puerto Rico.
The decision means an abrupt switch in the status of about 100 scientists, engineers and support staff at the observatory, who will no longer be on the Cornell payroll. "All of our staff are somewhat disoriented because they've been here 20, 30, 40 years and never considered they wouldn't be Cornell employees," says Sixto González, assistant director of space and atmospheric science at Arecibo and the site's former director.
Rumors of the change first appeared on the Internet last week and have since been confirmed by Cornell. "We wish SRI good luck in living up to the incredibly high standards we have set," says Ira Wasserman, chairman of Cornell's astronomy department.
Robert Kerr, a former director of Arecibo who was principal investigator on the successful bid, says that, to ensure a smooth transition, for the first year nothing will change about how applications for time on the facility are processed. Beyond that, Kerr says, partners in the consortium are "likely to bring forward new ideas and new science."
One thing that will change right away is the location of the observatory's director. Under Cornell, Arecibo's director was based remotely at the university's campus in Ithaca, N.Y. Under the consortium, the director--expected to be Kerr--will work on site.
Héctor Arce, an astronomer at Yale University in New Haven, Conn., who was born and raised in Puerto Rico, says it was widely felt that Cornell didn't do enough to partner with other institutions on the island. "That might have hurt Cornell," he says. In addition to including the Metropolitan University on the bid, the consortium will sponsor faculty positions at the University of Puerto Rico and will create a commission that will study other ways in which local institutions can get more involved with Arecibo.
Donald Campbell, a Cornell astronomer and the current director of the observatory, says Cornell submitted a serious proposal based on partnerships with seven institutions, including the University of Puerto Rico.
But Juan Arratia, an electrical engineer at the Metro¬politan University in San Juan, says that the Puerto Rican government supported the SRI consortium's bid through the government-owned Puerto Rico Industrial Development Company, the office of tourism and the Department of Education. Arratia, who led Metropolitan's part of the bid, expects that government sources will contribute around $5 million per year to the observatory. "That would be a real plus," says John Salzer, an astronomer at Indiana University Bloomington who works with data from Arecibo.
Astronomers rallied to support Arecibo after its closure was recommended in a 2006 NSF review. The facility is now likely to remain the most sensitive instrument of its kind for the foreseeable future. A 500-meter radio dish under construction in Guizhou, China, will not reach the higher frequencies that Arecibo can detect. The Square Kilometer Array, to be built in Australia or South Africa, would surpass Arecibo, but its construction is not expected to begin for several more years.
