From today, you can read the latest about the Prisma satellite project on www.prismasatellites.se

Prisma is a Swedish-led satellite project with the objective to develop and qualify new technology necessary for future science missions in space. Many of the future projects comprise formation flying and rendezvous, i.e. several spacecraft that can communicate and interact with each other with high precision and that requires exceptional accuracy in measuring and controlling the inter-satellite orientation.

Tonight and tomorrow, a Prisma event is held at SSC's premises in Solna, Sweden.
