RISAT 2 INDIAN SPY SATELLITE
ISRO today successfully launched two satellites RISAT 2 (Radar Imaging Satellite) and ANUSAT (Anna University Satellite) by PSLV C12 (Polar Satellite Launching Vehicle) from SDSC, SHAR, Sriharikota at 6.45 am. RITSAT 2 can conduct surveillance 24X7 in all weather condition and helps to keep watch on terror camps. It also helps in disaster management and mapping of natural resources. Although its mainly a surveillance satellite but neighbouring countries are watchful of it spying capabilities. US and other countries are said to placed such satellites in space in past and at one point of time there were dangers of star wars but disintegration of USSR has melt down the cat race. India needs such satellite because of cross border terrorist activities and to have a watchful eyes on terror camps, this satellite can help in to an extent in that field.

RISAT -2 (Radar Imaging Satellite)
RISAT-2  is  a Radar  Imaging  Satellite with  all  weather capability to take images of the earth.  This satellite will enhance  ISRO’s  capability  for  Disaster  Management applications.
Satellite Specifications
Altitude     550 km
Inclination  41 deg
Orbit Period  90 minutes
Mass     300 kg 
ANUSAT  (Anna University Satellite)
ANUSAT  (Anna University Satellite)  is  the  first  satellite built by an Indian University under the over all guidance of  ISRO  and will  demonstrate  the  technologies  related to message store and forward operations. It is a micro satellite built by Anna University, Chennai.

PSLV-C12 (Polar Satellite Launching Vehicle)
It weighs about 230 tonnes at lift off.  It may be recalled that PSLV in its core alone configuration had launched AGILE and TECSAR during 2007 and 2008 respectively.  This is PSLV’s 15th mission. PSLV is a four-stage launch vehicle employing both solid and  liquid  propulsion  stages.    PSLV  is  the  trusted workhorse  launch  Vehicle  of  ISRO.  During  1993-till now,  PSLV  had  fifteen  launches  of  which  fourteen  were  consecutively  successful.  PSLV  has  repeatedly proved  its  reliability  and  versatility  by  launching 30  spacecraft  (14  Indian  and  16  for  international customers)  into  a  variety  of  orbits  so  far.    It  may  be recalled  that during  its previous mission on October 22, 2008, PSLV had successfully launched   Chandrayaan-1 spacecraft, which  is now exploring  the Moon  from  lunar orbit.
