The Indian Space Research Organisation (ISRO) scripted history by successfully launching earth observation satellite RISAT-2B on Wednesday, May 22, that would enhance the country's surveillance capabilities among others. The new "spy satellite" will keep a lookout from space even in cloudy conditions.
ISRO used its Polar Satellite Launch Vehicle to launch the 615-kg RISAT-2B satellite that blasted off at 5.30 am from the first launch pad of the Satish Dhawan Space Centre in Andhra Pradesh's Sriharikota on its 48th mission. The RISAT-2B (Radar Imaging Satellite-2B), meant for application in fields such as surveillance, agriculture, forestry and disaster management support, was released into the orbit around 15 minutes after the lift-off. It would replace the RISAT-2, which was successfully launched in 2009.
Indian Space Research Organisation (ISRO) Chairman K Sivan had earlier described the mission as a "very, very important" one for the country. "This is a very, very important mission for India. It is an excellent satellite with hi-fi earth observation (capabilities)," he had said.
The RISAT-2B is equipped with a synthetic aperture radar that can take pictures of the earth during day and night, and also under cloudy conditions.

With a mission life of five years, the satellite would also be used for military surveillance, ISRO sources told a news agency.
The RISAT-2 has been actively used by India to monitor activities in camps across the border in Pakistan to thwart infiltration bids by terrorists.
The PSLV-C46 was the 14th flight of the PSLV in its core-alone configuration sans the use of the solid strap-on motors.
It was the 72nd launch vehicle mission from Sriharikota and also marked the 36th launch from the first launch pad.
Wednesday's launch of the PSLV also marked the third launch in 2019.
The other two were the PSLV-C45/EMISAT mission, which successfully injected the EMISAT and 29 international customer satellites into their orbits on April 1, and the PSLV-C44, which successfully placed the Microsat-R and the Kalamsat-V2 satellites in designated orbits on January 24.
ISRO had launched RISAT-1, a microwave remote sensing satellite, on April 26, 2012, from Sriharikota.
ISRO has made special arrangements for viewers to watch the PSLV-C46 launch live from the viewers' gallery situated in Sriharikota. However, viewers were not present at Sriharikota can watch the PSLV-C46 launch on Doordarshan and ISRO's official website.
