Antarctica Astronomy & Astrophysics Meeting in China

Antarctica provides one of the best environments on Earth for astronomical observation. Significant astronomical buildup is expected on the southernmost continent over the next decade to take advantage of these ideal conditions. Astronomers and astronomical engineers will come together in Xi’an China on August 18-21 to plan these next steps during the meeting entitled, “Astronomy & Astrophysics in Antarctica.” The goals for the meeting are to explore the site properties, evaluate the risks involved and assess the technical challenges in building astronomical instruments on the Antarctica Plateau. Additional topics for the meeting include prioritizing science programs for the upcoming years and exploring how to maximize international cooperation on the continent. Particular attention will be paid to Dome A, considered for many years to be the ultimate observing site on the plateau, and hence the Earth. With 4,093 m altitude (highest on the continent), low water vapor content and average winter temperatures of -70 degrees C (coldest on Earth), Dome A is seen as an ideal site for infrared and sub-millimeter observations. During the meeting, Michael Ashley (BL), of the California Institute of Technology, will speak about PLATO operations and Dome A site properties and Li-Fan Wang (BR), of the Chinese Center for Antarctic Astronomy (CCAA), will give a lecture on Antarctica Schmidt Telescopes. Cosponsors include the CCAA, Key Laboratories of Radio Astronomy and the National Astronomical Observatories, CAS. (Credit: unsw.edu.au, tamu.edu, NAOC, CCAA)

Aquarius Satellite Mission Focus of von Karman Lecture Series

The Jet Propulsion Laboratory in Pasadena CA will hold the next von Karman Lecture Series, ‘Aquarius: Studying Sea Surface Salinity (SSS) from Space’ on August 19-20. Guest lecturer and Aquarius Project Manager Amit Sen (BR) will discuss the satellite mission set to launch NET 2011. Data gathered will provide the 1st global observations of SSS and an in-depth understanding of the correlation between the Earth’s water cycle, ocean circulation and climate. Set to last 3 years, the mission will deliver 150km resolution SSS maps and achieve an accuracy of 0.2 psu, approximately a ‘pinch’ of a teaspoon of salt in 3.8L of water. The science instruments on board Aquarius include 3 radiometers for salinity detection and a scatterometer to ensure correct readings. By tracking SSS, scientists can monitor land runoff, melting / freezing of sea ice and evaporation / precipitation over the oceans to predict future climate conditions. The mission is currently being developed by NASA JPL and GSFC as well as international cooperation with the Argentina space agency, Comision Nacional de Actividades Espaciales (CONAE). The mission is expected to cost US$242 million. (Credit: NASA, CONAE)
