In an era defined by intensifying technological rivalries and the rapid expansion of extraterrestrial capabilities, the protection of Earth's orbital commons has emerged as one of the most critical frontiers of modern multilateral diplomacy. At the eighteenth summit hosted in New Delhi, the expanded BRICS bloc placed orbital security and scientific equity high on the international agenda. In adopting the consensus New Delhi Declaration, member nations issued a clear and collective appeal backing the peaceful exploration and use of outer space while reaffirming their steadfast commitment to preventing an arms race and weaponization beyond Earth’s atmosphere. The summit positioned emerging economies as decisive stewards of space governance, advocating for universal legal protections, transparent international norms, and cooperative scientific ventures designed to serve humanity rather than geopolitical militarization.
The declaration firmly underlined that space science, orbital infrastructure, and satellite technologies must remain exclusively oriented toward peaceful purposes, socio-economic progress, and sustainable planetary development. Leaders recognized that as access to low-Earth orbit and deep-space missions proliferates, the boundary between defensive surveillance and offensive capability is growing increasingly blurred. To counter this destabilizing trend, the alliance called for urgent international negotiations toward adopting a comprehensive, multilateral, legally binding instrument aimed at guaranteeing outer space security. Member states emphasized that non-binding political commitments, while constructive in building initial trust, cannot substitute for codified international law capable of deterring the weaponization of the cosmos.
Central to this legal framework is the long-standing international initiative known as the Prevention of an Arms Race in Outer Space, or PAROS. Within the New Delhi Declaration, BRICS leaders specifically referenced the updated Draft Treaty on the Prevention of the Placement of Weapons in Outer Space and of the Threat or Use of Force against Outer Space Objects, originally submitted to the Conference on Disarmament. The document was lauded as an indispensable foundation for future global agreements. Alongside binding legal treaties, the bloc highlighted the complementary value of practical Transparency and Confidence-Building Measures. These voluntary steps, combined with universally agreed norms and principles, create predictable operational guardrails, reduce the likelihood of miscalculation between rival space programs, and establish mutual accountability across launch activities and orbital maneuvers.
The diplomatic push also extends directly into United Nations governance mechanisms. BRICS members highlighted ongoing initiatives within the United Nations General Assembly to establish a single, comprehensive Open-Ended Working Group tasked with centralizing, streamlining, and advancing discussions on outer space threats. Leaders pledged constructive engagement in this multilateral process, stressing that the future rules of space exploration must be authored inclusively by the broader international community, including emerging markets and the Global South, rather than dictated by a select few legacy space powers. This stance reflects a wider geopolitical philosophy that champions a multipolar world order, sovereign equality, and equitable technological access across all domains of shared human heritage.
Beyond security and arms control, the summit placed significant emphasis on the practical, long-term environmental sustainability of outer space activities. Acknowledging the discussions held during the BRICS Heads of Space Agencies meeting in Bengaluru earlier in the year, the declaration placed special focus on space-debris mitigation. Decades of orbital activity, satellite breakups, and anti-satellite missile testing have filled critical orbits with millions of high-velocity fragments, posing an escalating operational threat to active telecommunication arrays, Earth observation systems, weather monitors, and manned space platforms. By championing shared debris-tracking protocols, coordinated collision-avoidance strategies, and responsible spacecraft de-orbiting practices, member states seek to ensure that outer space remains usable for future generations.
The cooperative ethos championed at the summit is already mirrored in operational multilateral initiatives, most notably the BRICS Remote Sensing Satellite Constellation. By integrating satellite assets and data streams from member agencies—such as the Indian Space Research Organisation, the China National Space Administration, and Russia’s Roscosmos alongside fellow member state space bodies—the grouping has demonstrated how shared technology directly solves terrestrial challenges. Constellation data is routinely mobilized to monitor real-time climate patterns, forecast agricultural yields, manage cross-border natural disasters, assess water security, and support resilient infrastructure planning. These practical applications highlight how space exploration, when stripped of military posturing, functions as an engine of sustainable economic growth for developing and emerging societies.
The declaration’s decisive language arrives at a pivotal juncture for the commercial and sovereign space sectors. The rapid commercialization of low-Earth orbit by private megaconstellations, coupled with defense strategies that treat space as an operational warfighting domain, has heightened global anxiety over prospective satellite jamming, directed-energy weapons, and kinetic orbital strikes. By establishing a unified diplomatic stance against weapon deployment and hostile acts against space objects, BRICS is seeking to break the diplomatic stalemate that has stalled progress at the Conference on Disarmament for years.
Ultimately, the outcomes of the New Delhi summit reinforce the principle that the cosmos belongs equally to all nations, regardless of their economic wealth or launch frequency. By combining calls for legally binding arms prohibitions with actionable environmental commitments like debris reduction and expanded satellite data sharing, the bloc has laid down a comprehensive blueprint for peaceful engagement. As orbital traffic expands exponentially in the decades ahead, the path outlined in New Delhi demonstrates that safeguarding orbital peace depends on sustained multilateral consensus, transparent dialogue, and an unshakeable commitment to treating outer space as a shared sanctuary for global scientific advancement.
