SAMENA Council Leads Space Sustainability Dialogue and Contextualizes
WRC-27

In September, SAMENA Telecommunications Council, at the
Mohammed Bin Rashid Space Centre (MBRSC) headquarter, led WRC-27 Preliminary Agenda Items
a dialogue on space sustainability, organized by the World Space On the basis of proposals from Administrations and
Sustainability Association (WSSA). Held as Space Sustainability the Report of the Conference Preparatory Meeting, and
Leaders Forum, the roundtable discussion led by SAMENA Council taking account of the results of WRC-23, to consider
