On October 12, 2011, ISRO launched this satellite into Ningi in collaboration with the French Space Agency for forecasting Earth’s weather conditions. However, after 2021 its performance has completely stopped. At a time when Chinese space debris often enters the Earth’s atmosphere and becomes dangerous, ISRO aims to prevent such situations from occurring with Indian satellites. 27 thousand km per hour. ISRO has proven to have the capability to shoot down obsolete and obsolete satellites by destroying the Megha-tropicus orbiting at high speed.
From August 2022, the satellite’s perigee will be gradually reduced through 20 strategic series, burning 120 kg of fuel. The final de-boost strategy was formulated after considering several maneuvers and constraints. These take into account re-entry trace visibility on ground stations, ground effect in the target zone, allowable operating conditions of the co-systems, in particular the ability to fire the thrusters at maximum.
The last two de-boost burns on March 7 at 11:02 am and 12:51 pm respectively ignited the satellite’s four 11 Newton thrusters for 20 minutes, ISRO said. The final perigee is estimated to be less than 80 km, which indicates that the satellite enters the densest layers of the Earth’s atmosphere and subsequently undergoes structural disintegration. Also, the re-entry aero-thermal flux analysis confirmed that no large fragments remain. So far only China, Russia and America have such capability. Recently, India stood against those countries.
