This article examines the participation of a Brazilian university in the European Space Agency's PLATO mission to explore how large-scale scientific collaborations can foster science diplomacy while simultaneously revealing the institutional and structural constraints faced by emerging countries. Drawing on a qualitative approach and a literature review, the single-case study contributes to the Research Topic \u201cLinking Knowledge Across Borders: Science Diasporas and Global South Development\u201d analyzing how a Brazilian laboratory contributed to the mission between 2009 and 2024. Initially conceived as a scientific cooperation project, the initiative gradually came to involve an increasing number of Brazilian state actors, expanding its significance beyond its original technical objectives. The findings show mechanisms by which international collaboration strengthened institutional relationships and diplomatic engagement, constituting a case of Science for Diplomacy and enhancing Brazil's international visibility. At the same time, the case highlights how Global North\u2013South asymmetries, governance arrangements, and domestic institutional limitations shape the opportunities and challenges of the Global-South participation in large-scale scientific and technological initiatives.<\/jats:p>","DOI":"10.3389\/frma.2026.1856162","type":"journal-article","created":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T05:32:29Z","timestamp":1785994349000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Science diplomacy in the Global South: a case study of Brazilian participation in the PLATO mission"],"prefix":"10.3389","volume":"11","author":[{"given":"Daniel","family":"Dalla Vecchia Gueter","sequence":"first","affiliation":[{"name":"Laboratory of Embedded Electronic Systems, Mau\u00e1 Institute of Technology","place":["S\u00e3o Caetano do Sul, Brazil"]},{"name":"FESPSP \u2013 S\u00e3o Paulo School of Sociology and Politics","place":["S\u00e3o Paulo, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Flavia","family":"Loss de Araujo","sequence":"additional","affiliation":[{"name":"Laboratory of Embedded Electronic Systems, Mau\u00e1 Institute of Technology","place":["S\u00e3o Caetano do Sul, Brazil"]},{"name":"Institute of Advanced Studies, University of S\u00e3o Paulo","place":["S\u00e3o Paulo, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexandre","family":"Ramos Coelho","sequence":"additional","affiliation":[{"name":"FESPSP \u2013 S\u00e3o Paulo School of Sociology and Politics","place":["S\u00e3o Paulo, Brazil"]},{"name":"FAAP \u2013 Armando Alvares Penteado Foundation","place":["S\u00e3o Paulo, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodrigo","family":"de Marca Fran\u00e7a","sequence":"additional","affiliation":[{"name":"Laboratory of Embedded Electronic Systems, Mau\u00e1 Institute of Technology","place":["S\u00e3o Caetano do Sul, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vanderlei","family":"Cunha Parro","sequence":"additional","affiliation":[{"name":"Laboratory of Embedded Electronic Systems, Mau\u00e1 Institute of Technology","place":["S\u00e3o Caetano do Sul, Brazil"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,8,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1093\/scipol\/scaf053","article-title":"Building international science and innovation diplomacy networks for the advancement of science in the Global South","author":"Awan","year":"2025","journal-title":"Sci.
