Satellite News

Satellites are used for a large number of purposes. Common types include military (spy) and civilian Earth observation satellites, communication satellites, navigation satellites, weather satellites, and research satellites.

2009 is being celebrated worldwide as the "International Year of Astronomy (IYA)". Indian Space Research Organisation (ISRO) is one of the organisational associates of IYA. The details of the national program on IYA activities in India is available at Inter University Centre for Astronomy & Astrophysics (IUCAA).

The Indian space program has always encouraged the study of the universe using space as a platform. The research work in the areas of cosmic rays, infrared, X-rays, gamma ray and solar physics were initially carried out using high altitude balloons and rockets. Today many of these studies are carried out using satellite experiments. Since 90s, opportunities to fly space science experiments have increased and numerous science payloads have been deployed as piggyback systems on several satellites from India. These include:

* SROSS-series GRB experiments.
* IXAE on IRS-P3.
* SOXS on GSAT-2.

More recently, ISRO has undertaken development of dedicated satellites for space sciences. The first of these CHANDRAYAAN-1 was launched on October 22, 2008, marking India's entry into solar system exploration studies. CHANDRAYAAN-1 will soon be followed by a dedicated multi-wavelength astronomy satellite ASTROSAT, slated for 2010 launch.
