Zero Gravity Graphene (IMAGE) Graphene Flagship Caption Two experiments this year will test graphene in different space-related applications for use in satellites. Graphene-based solar sails will be tested in microgravity in a drop-tower experiment, while graphene-modified heat pumps for onboard satellite electronics will be tested in a parabolic flight.
