ISRO launched RISAT-2B, a cloud-proof spy satellite on May 22


Indian space research agency (ISRO) has successfully launched an earth observation spy satellite RISAT-2B(Radar Imaging Satellite-2B) on May 22, 2019. RISAT-2B is capable of taking high-resolution images of the earth during day and night, even under cloudy conditions. This satellite is launched to keep an eye on terror camps across the border of Pakistan to help the Armed forces. Apart from keeping an eye, it is also helpful for agriculture, forestry, disaster management support, and surveillance.

This satellite is launched by PSLV - C 46 / RISAT-2B from Sathish Dhawan Space Centre SHAR, Sriharikota. It is launched in an orbit 557 km above the ground. This is ISRO's second spy satellite. Prior to RISAT-2B, ISRO has launched RISAT-2 in 2009 and Risat-1 satellites in 2012. RISAT-2 has been used by India to monitor activities in terror camps across the border in Pakistan to beat inappropriate activities by terrorists. RISAT-2B would enhance the surveillance and monitoring for the security of India.

The satellite consists of a synthetic aperture radar which is capable of taking pictures in any weather conditions. It has a life span of five years. The aperture radar helps to give details about the size of objects on Earth, structures, movement, and change.
