Delfi‑n3Xt is the successor of Delfi‑C3. It is a triple-unit CubeSat demonstrating a micro-propulsion system, amorphous hydrogenated Silicon solar cells, a new radio platform, an agile electrical power subsystem and an active attitude control subsystem.

The Delfi‑n3Xt project initiated in 2007 and the satellites was launched on the 21st of November 2013 from Russia. The satellite operated successfully for three months, fulfilling its main mission objectives and achieving mission success! Unfortunately, contact with the satellite was lost after an experiment with the linear transponder.
