GRAIL Successfully Maps and May Impact Lunar Surface
Gravity Recovery and Interior Laboratory lunar orbiting spacecraft, Ebb and Flow, are approaching the end of their extended science operations mission, pushed back from December 3 to Dec 17. GRAIL operated at unprecedented altitudes of about 23 km above the Moon. In some cases they were only 8 km above the highest surfaces and soon they may get a lot closer. The US$496M GRAIL mission plan includes a 5-day decommissioning period and it is speculated that approximately 40 days later GRAIL will impact the lunar surface. The specific crash site for the 200-kg near-twin spacecrafts has not yet been designated. On Dec 6 and 7, Dr. Sami Asmar (L) GRAIL Deputy Project Scientist of JPL will speak about the project at The von Kármán Lecture Series ‘GRAIL Unwraps the Moon’ in Pasadena, California, USA. Data analysis from the GRAIL primary mission is expected to continue until at least August 2013, advancing our knowledge about the interior, gravity field and evolution of the Moon and other planets in the Solar System. As part of the NASA Discovery Program in which lower-cost, highly-focused American scientific space exploration missions are the focus, GRAIL data will greatly benefit upcoming missions to the Moon and beyond.

NAO Japan Explores Present and Future of Radio Astronomy in the ALMA Era
In celebration of the 30th Anniversary of the 45-meter Nobeyama Radio Observatory in Nagano the National Astronomical Observatory of Japan is hosting an international symposium on ‘New Trends in Radio Astronomy in the ALMA Era’ on December 3-8 in Hakone, Kanagawa Prefecture. The primary purpose of the symposium is to discuss new and future trends expected for Radio Astronomy on the basis of initial outcomes from early science in cosmology, galaxies, star / planet formation, the solar system and interstellar matter at ALMA – the Atacama Large Millimeter/submillimeter Array, a US$1.3-B international project based in the Atacama Desert of Chile. Pierre Cox, incoming Director of ALMA effective April 1, 2013, is presenting on ‘IRAM: Present and Future’ on Friday Dec 7 at 10:05. Also in the ‘Future Plans’ session on Friday are Gordon Stacy ‘The CCAT Project’ (11:15) and Sheperd Doeleman ‘The Event Horizon Telescope’ (14:25). On Tuesday November 20, North America completed delivery of 25 NSF-funded 12-meter-diameter 110-ton dish antennas. These are being joined by 25 from Europe and 16 from East Asia spread out over almost 200 square kilometers. The latest count shows 52 of the total 66 dishes have been delivered to the 5,000-meter altitude Array Operations Site on the Chajnantor Plateau. (Image Credit: NAOJ, ALMA, Hakone Town)
