  • RISAT-2, made an uncontrolled re-entry into the Earth's atmosphere at the predicted impact point.
  • It was launched by the Indian Space Research Organisation (ISRO) in 2009.
  • RISAT-2 Satellite carried 30 Kg of fuel for an initial designed life of four years.
  • By economical usage of fuel RISAT-2 provided very useful payload data for 13 years.
  • The pieces generated due to aero-thermal fragmentation would not have survived re-entry heating and hence no fragments would have impacted on Earth.
