Prisma’s Tango and Mango satellites

Swedish Prisma is a technology mission demonstrating different sensor technologies and guidance/navigation strategies for rendezvous and formation flying in space. The project consists of two satellites, one advanced and highly manoeuvrable (Tango, left) and one simplified (Mango) to be connected to Tango through precision-manoeuvring. Prisma was launched 15 June 2010 by a Russian Dnepr rocket. The mission will last about 10 months.
