Why is transnational STS needed and what does it look like in practice? What relationships and infrastructures does transnational STS depend on, perpetuate, and challenge? This open panel will explore different reasons and ways people pursue transnational STS, considering transnational STS a method and project design challenge. This open panel extends from extensive dialogue about TRANSnational STS at the 2018 annual 4S conference in Sydney, which spawned an array of new collaborations and further conversation. This open panel is intended to keep the dialogue going and open, taking transnational STS in new directions. In line with the theme of the 4S 2021 Toronto Conference, the panel will approach transnational STS as a space to work out decolonial, anti-racist and anti-authoritarian relations,  supporting vibrantly pluralistic knowledge production. The aim of the panel is to juxtapose different approaches and projects, learning across their differences.  We encourage papers that present past, on-going or imagined transnational projects, drawing out what they aim to achieve, what they are designed against, their workflows, modes of collaboration, infrastructures and governance. Contributions may address, among others, the following questions:
-What motivates transnational collaborations in STS and what do they aim to achieve?
-What methods and infrastructures are used in transnational STS projects?
-How are data in transnational STS projects shared and managed?
-How are transnational STS research projects administered and governed?
-What relationships are engendered and valued in transnational STS projects?
-How have differences in political contexts shaped transnational STS projects?
-What challenges have emerged in transnational STS projects? What is needed to move through them?
-How have transnational STS projects actively leveraged diverse intellectual genealogies?
-How have transnational STS projects been proactively anti-imperial?
-What has been learned in transnational STS projects about the workings of  “team science” and international research networks?
-What have transnational STS projects accomplished and what is their future?
