India's defunct Radar Imaging Satellite-2 (RISAT-2) re-entered the earth atmosphere on October 30 in an uncontrolled manner and hit the Indian Ocean near Jakarta, said Indian Space Research Organisation (ISRO).

The 300 kg RISAT-2, a surveillance satellite, was launched on April 20, 2009, using the Polar Satellite Launch Vehicle (PSLV).

The satellite with a design life of four years had initially carried 30 kg of fuel for operations in the space.


According to ISRO, the satellite did not have any fuel when it re-entered the earth atmosphere and studies confirmed that the pieces generated due to aero-thermal fragmentation would not have survived re-entry heating and hence no fragments would have impacted the earth.

The re-entry of the satellite was monitored by ISRO with the Multi Object Tracking Radar (MTOR) at the Sriharikota rocket port and with software analysis, the space agency said.

"As RISAT-2 re-entered within 13.5 years, it complied with all necessary international mitigation guidelines for Space Debris, showing ISRO's commitment towards long term sustainability of Outer Space as well," ISRO asserted.
