Notice of Intent To Prepare an Environmental Impact Statement and Initiate Section 106 Consultation for Proposed Changes to Arecibo Observatory Operations, Arecibo, Puerto Rico and Notice of Public Scoping Meetings and Comment Period, NSF
"Through a series of academic community-based reviews, NSF has identified the need to divest several facilities from its portfolio in order to retain the balance of capabilities needed to deliver the best performance on the key science of the present decade and beyond. In 2012, NSF's Division of Astronomical Sciences' (AST's) portfolio review committee recommended that ``continued AST involvement in Arecibo . . . be re-evaluated later in the decade in light of the science opportunities and budget forecasts at that time.'' In 2016, NSF's Division of Atmospheric and Geospace Sciences' (AGS') portfolio review committee recommended significantly decreasing funding for the Space and Atmospheric Sciences portion of the Arecibo mission. In response to these evolving recommendations, in 2016, NSF completed a feasibility study to inform and define options for the observatory's future disposition that would involve significantly decreasing or eliminating NSF funding of Arecibo."
"China's gigantic Five hundred meter Aperture Spherical Telescope (FAST) is nearing completion in China's southwestern Guizhou Province and will soon begin searching the skies for phenomena including signs of extraterrestrial life. Construction of 500m diameter, 1.2 billion yuan (US$185mln) radio telescope began in 2011 and is on course to come online in September, when it will become the world's largest and most sensitive radio telescope."
