Megha-Tropiques-1 (MT-1) Satellite:
The Indian Space Research Organisation (ISRO) successfully carried out the controlled re-entry experiment for the decommissioned Megha-Tropiques-1 (MT-1) satellite.
- Due to the increasing number of objects in space (Space Debris), the international aerospace community has adopted guidelines and assessment procedures to reduce the number of non-operational spacecraft and spent rocket upper stages orbiting the Earth.
- One method of post mission disposal is to allow the reentry of these spacecraft, either from natural orbital decay (uncontrolled) or controlled entry.
- Orbital decay or uncontrolled is One way to accelerate orbital decay is to lower the perigee altitude so that atmospheric drag will cause the spacecraft to enter the Earth’s atmosphere more rapidly.
- Controlled entry normally is achieved by using more propellant with a larger propulsion system to cause the spacecraft to enter the atmosphere at a steeper flight path angle.
- The vehicle will then enter the atmosphere at a more precise latitude and longitude, and the debris footprint can be positioned over an uninhabited region, generally located in the ocean.
