The NSF Astronomy Division convened a "Senior Review" http://www.nsf.gov/mps/ast/ast_senior_review.jsp to try and see where money could be saved to pay for the enormous operating costs of ALMA http://www.alma.nrao.edu/ which is the Atacama Large Millimeter Array. ALMA will be an array of some 64 12-meter antennas operated at an elevation of 5000 m (16,000+ ft). ALMA is a collaboration between the Europeans, Japan, Chile and the US.

Arecibo was a loser in the Senior Review; something has to give to pay for ALMA operations!
