Topics of discussions included review of national legislation relevant to the peaceful exploration and use of outer space, use of nuclear power sources in outer space, information on national mechanisms relating to space debris mitigation measures as well as other initiatives in the development of international legal regime of outer space that complement five treaties and five sets of declarations and principles of the United Nations on outer space activities.
