Abstract. The publication presents the results of an in-depth study of the provisions of the BRICS Kazan Declaration of 2024 related to the problems and strengthening of the global security architecture in the space sphere, as well as the author’s judgments on the prospects for joint efforts of states on BRICS platforms to ensure security in space in the interests of humanity. A literature review was conducted, problems in the scientific study of the role of BRICS in the architecture of global security in the space sphere were identified. The position of BRICS on security issues in space, reflected in the BRICS Kazan Declaration and documents of the summits of previous years, was studied. It is stated that cooperation of the BRICS countries in ensuring security in the space sphere is focused on the dyad of goals of forming the long-term sustainability of space exploration activities and preventing an arms race in outer space. It is noted that there is insufficient progress in achieving the BRICS goals in global space security, but with the club consistently expressing and defending key positions. Political and other factors of insufficient success of joint activities in the subject area are highlighted. Among the most promising applications of joint efforts of states on BRICS platforms to ensure security in space in the interests of humanity, in addition to achieving progress in international regulation, are the creation of a specialized permanent BRICS body on peaceful exploration of outer space and security in outer space, the development and adoption of a joint strategy for space exploration, the activation of technology and knowledge exchange programs between the BRICS countries to reduce the technological gap, the implementation of initiatives to create multilateral mechanisms for monitoring space activity, as well as the development of new codes of conduct to prevent conflicts in space.
