Prisma is a satellite project led by the Swedish Space Corporation (SSC) which consist of two satellites that fly in formation.
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. A secondary objective was to flight test a new monopropellant thruster using ammonium dinitramide (ADN) propellant.
On 12 August 2010, SSC reported that the two satellites, called Mango and Tango, had separated from each other for the first time.
