The first images from RISAT-2, the all-weather spy satellite put into orbit by a Polar Satellite Launch Vehicle (PSLV) on Monday, will start arriving next week, Isro said.
Isro's chief spokesman S Satish said on Tuesday that there would be no further altitude-raising operation for RISAT-2 and Anusat, the country's first university satellite that piggy-backed on the spy satellite.

The new satellite bolsters India's presence in space. Last year, Israel launched the TECSAR satellite from India that, like the RISAT, uses radar to create high-resolution images. Israel also operates the Ofek 5, Ofek 7, Eros A and Eros B spy satellites.

Out of the 15 satellite launch missions it has flown since 1993, Indian Space Research Organisations (ISRO) rocket Polar Satellite Launch Vehicle (PSLV) has delivered successful results except for once.
The failure happened on its first developmental flight Sep 20, 1993. After the success of the next two developmental flights there has been no looking back for the 44 metre tall workhorse of the ISRO.

In its fifteenth mission carried out from Satish Dhawan Space Centre SHAR (SDSC SHAR), Sriharikota today (April 20, 2009), ISRO's Polar Satellite Launch Vehicle (PSLV-C12) successfully placed two satellites - RISAT-2 and ANUSAT - in the desired orbit.
RISAT-2 is a Radar Imaging Satellite with the capability to take images of the earth during day and night as well as cloudy conditions.
At the time of launch, RISAT-2 weighed about 300 kg and was realised by ISRO in association with Israel Aerospace Industries. The satellite was placed in an orbit of 550 km height with an inclination of 41 deg to the equator and an orbital period of about 90 minutes. This satellite will enhance ISRO's capability for earth observation, especially during floods, cyclones, landslides and in disaster management in a more effective way.

India has launched an Israeli-built spy satellite to boost its surveillance capabilities after last year's Mumbai attacks exposed glaring holes in its defence apparatus.
The satellite, RISAT 2, was launched from the Sriharikota launch site, 90km north of the southern city of Chennai, on Monday.
