An International Asteroid Warning Network (IAWN) linking together the institutions that are already performing many of the proposed functions, including: discovering, monitoring and physically characterizing the potentially hazardous NEO population; maintaining an internationally recognized clearing house for the receipt, acknowledgment and processing of all NEO observations; recommending policies regarding criteria and thresholds for notification of an emerging impact threat; and developing a strategy using well-defined communication plans and protocols to assist Governments in the analysis of impact consequences and in the planning of mitigation responses.

A Space Mission Planning Advisory Group (SMPAG) of Member States with space agencies, facilitated by the United Nations on behalf of the international community, with no financial implications for the budget of the United Nations. Its responsibilities should include laying out the framework, timeline and options for initiating and executing response activities, informing the civil-defence community about the nature of impact disasters and incorporating that community into the overall mitigation planning process through an impact disaster planning advisory group.

IAWN and SMPAG held on 18th February at the sidelines of the 53rd session of STSC a dedicated Open forum on near-Earth Object impact hazards


In 2001 the Committee on the Peaceful Uses of Outer Space (COPUOS) established the Action Team on Near-Earth Objects (Action Team 14). The Action Team met throughout the years at NEO-related conferences, on the margins of COPUOS and the Subcommittee meetings, as well as working intersessionally in an informal manner. Building upon the recommendations of the Action Team, the General Assembly approved the plan for the Scientific and Technical Subcommittee (STSC) of COPUOS to being a multi-year work plan on NEOs, beginning on 2007, that would review progress on international cooperation and collaboration on NEO observations, facilitate, for the purpose of NEO threat detection, a more robust international capability for the exchange, processing, archiving and dissemination of data, draft international procedures for handling the NEO threat and seek agreement on those procedures.

The GA also established the Working Group on Near Earth Objects, under the STSC. The recommendations were approved by STSC during its 50th session, held in February 2013, and formally endorsed by the Committee at its 56th session in June 2013 and by the 68th session of the GA in December 2013 (Resolution 68/75).As a result of the work of the Action Team 14 IAWN & SMPAG where established. After the first meetings of IAWN and SMPAG in 2014 the Action Team on NEOs, having successfully completed its mandate, was dissolved in 2015 by the STSC.
