Prisma is a satellite project led by the Swedish Space Corporation (SSC) which consist of two satellites that fly in formation.[1] Prisma is operated in collaboration with CNES, the French space agency, which provides the radiofrequency metrology system that enables the satellites to fly in close formation while autonomously avoiding collisions.[3]

It was launched, along with the PICARD spacecraft, on 15 June 2010 on a Dnepr launcher from Dombarovskiy Cosmodrome, near Yasny, Russia. Its primary objective is to test autonomous formation flying.[1][4] A secondary objective was to flight test a new monopropellant thruster using ammonium dinitramide (ADN) propellant.[5]

On 12 August 2010, SSC reported that the two satellites, called Mango and Tango, had separated from each other for the first time.[6]
