As part of a collaboration between the Graphene Flagship and the European Space Agency, experiments testing graphene for two different space-related applications have been performed. These have been reported to show very promising results, based on which the Flagship is to continue the development of graphene devices for use in space.
Graphene's excellent thermal properties are promising for improving the performance of loop heat pipes, thermal management systems used in aerospace and satellite applications. Graphene could also have a use in space propulsion, due to its lightness and strong interaction with light. The Graphene Flagship tested both these applications in recent experiments in November and December 2017.
