India's spy satellite RISAT launched

The PSLV-C12, carrying 300-kg Radar Imaging Satellite (RISAT-2) and 40-kg Micro Satellite ANUSAT lifted off from ISRO’s Satish Dhawan space Centre here on Monday morning. At the end of the 48-hour countdown, the 44-meter tall four-stage PSLV-C12 blasted off from the second launch pad with the ignition of the core first stage.

The Polar Satellite Launch Vehicle, weighing 230 tonnes at the time of launch, soared into a clear sky at 6.45am(local time) from the spaceport here, about 90 km north of Chennai. This is the 15th flight of ISRO’s workhorse PSLV, which had launched 30 satellites (14 for India and 16 for foreign countries) into a variety of orbits since 1993.

The launch vehicle carries two payloads – RISAT-2 (with all weather capability to take images of Earth) and ANUSAT (the first satellite built by an Indian University to demonstrate the technologies related to message store and forward operations).

The rocket would place both the satellites in their orbits around the earth shortly. The SAR, developed by Israel Aerospace Industries, gives RISAT defence capabilities.

ANUSAT is the first satellite developed by an Indian university (Anna University), which would demonstrate the technologies related to message storing and forward operations. University sources said scores of students and faculty from different streams had worked on this satellite for the last six years.

ANUSAT is a store-and-forward communication satellite that will help transfer confidential academic materials, including exam question papers, to prevent question paper leakages. It will also help monitor drought and wasteland, urban planning and other studies.
