PRL surface soils and rocks was a landmark achievement of the is also continuing its efforts to enhance research in Planetary Chandrayaan-1 mission that received global acclaim. Sciences in the country by supporting and nurturing Association of PRL in the study that culminated in this research programme at various academic and research major scientific result has made the last year a very eventful institutes and universities through the ISRO sponsored one for us. The Chandrayaan-1 mission has yielded a wealth PLANEX program. of new data on lunar landform, mineralogy, chemistry and Scientific activities conducted at PRL during the year yielded radiation environment that are being analyzed by eleven a significant number of new results. Some of these are science teams across the globe. New findings from these outlined in the section on “Scientific Highlights”. The studies were presented by the science teams at a “Science” section covers detail reports of scientific activities Chandrayaan-1 Science Meet organized at PRL early this carried out by the different research divisions that include year. These findings have revealed new facets of lunar Astronomy and Astrophysics, Solar Physics, Planetary science and are providing newer insights about our nearest Sciences, Space and Atmospheric Sciences, Geosciences Solar System neighbour.

I have a great pleasure in presenting this report to the International Union of Geodesy and Geophysics (IUGG) at its General Assembly in Melbourne, Australia during 28th June, to 7th July, 2011. The report summarizes Indian activities in the geophysics and geodesy for the period of January 2007 to December 2010 and is structured to reflect eight associations of IUGG. The quadrennium 2007-2010 has been very exciting for the earth system sciences internationally and India is no exception to it. Four International Science Years namely, International Year of Planet Earth (IYPE, 2007-2009), International Polar Year (IPY, 2007-2008), Electronic Geophysical Year (EGY, 2007-2008) and International Heliophysical Year (IHY, 2007) were successively complemented during this period. These years have brought a lot of visibility and importance to the earth science research. India was a lead associate of these initiatives. Indian researchers have been actively involved in the Antarctic and Arctic studies and assessments of Himalayan glaciers, which have been summarized by Rasik Ravindra in the chapter on Cryospheric Sciences.

The response to this was encouraging and about sixty geophysicists responded to this invitation. These geophysicists who enrolled themselves as Members of the Union were styled as Foundation Fellows. The Indian Geophysical Union was formally inaugurated by Prof.Humayun Kabir, the then Minister for Cultural Affairs and Scientific Research (Govt. of India) in the year 1963, at a pleasant function organized in the Geology Department, Osmania University. Dr.D.S.Reddy, the then Vice-Chancellor, Osmania University, presided over the function. Dr.S.Bhagavantam, the then Scientific Adviser to Defence Minister welcomed the guests. Dr.K.R.Ramanathan, first President of the Union, delivered the Presidential address. Dr.M.S.Krishnan explained the aims and objectives of the Union and presented the draft constitution, which was revised in 1964, it was marginally amended in 1998.
