The 25th edition of the  UN/Austria Symposium took place from 2 to 4 September 2019 in Graz under the title “Space: A tool for Accessibility, Diplomacy and Cooperation”. During the Symposium, presentations, panel discussions, workshops and demo sessions aimed at providing a view of how space can function as a tool for cooperation and diplomacy as well as of how the use of space data and technology can be enhanced. Due to the success of the multidisciplinary approach adopted during the two previous Symposia, in 2019 the focus was again not only on space science and technology but also on space law and policy.
