Problem of Waste Deposits in Space

India has done studies related to waste deposits in space referred as Space Debris and successfully developed methodologies and software tools. ISRO performs Space Object Proximity Analysis for its operational Low Orbit spacecrafts on a regular basis to assess the collision risk and determine risk mitigation strategies in advance. Collision Avoidance analysis is also carried out to identify the safe lift-off time for launching of satellites from Sriharikota. The growing space debris poses threat to present and future space activities, globally, in terms of collision risk.

ISRO has taken mitigation measures like passivation of spent upper stage of launch vehicles and de-orbiting of non-functional satellites to avoid creation of space debris. ISRO has also undertaken collaborative studies with other space agencies to control and restrict this outer space contamination. India is a active member of Inter Agency Space Debris Co-ordination Committee (IADC) and played a key role in evolving space debris mitigation guidelines formulated by IADC and United Nations Committee on the Peaceful Uses of Outer Space (UNCOPUOS).
