Prism ( P rototype R esearch I nstruments and S pace M ission technology A dvancement ) is the name of a Swedish satellite mission. The mission consists of two satellites built by the Swedish space company Swedish Space Corporation (SSC) on behalf of the national space agency SNSB , which are to be used to test formation flight and communication. 1N control engines are also to be tested, which use the new single-component rocket fuel LMP-103S , which is significantly less toxic than the hydrazine used up to now and yet achieves a higher specific impulse .

Both satellites were launched together with the French solar research satellite Picard on June 15, 2010 with a Dnepr rocket from the Jasny cosmodrome in Russia . The smaller satellite ( Tango ) weighing around 40 kg was separated from the 140 kg mother satellite ( Mango ) in orbit on August 12, 2010 . A series of experiments were then carried out. The mother satellite can be steered in all three axes and actively approaches the smaller satellite. For this purpose, the two cube-shaped satellites are equipped with highly sensitive sensors such as GPS receivers. The ground station only communicates with Mango, not with Tango.

From March 15, 2011, control of the Prisma Mission was taken over for five months by the German space control center in Oberpfaffenhofen.
