Delfi-n3Xt is a Dutch nanosatellite which is operated by Delft University of Technology.[3] It was launched on 21 November 2013.[4] It is a three-unit CubeSat which will be used to demonstrate propulsion and communications systems for future missions.[5]

Delfi-n3Xt was launched successfully by a Dnepr carrier rocket flying from Site 370/13 at the Dombarovsky launch site. Delfi was a secondary payload aboard the rocket, whose primary mission was to deploy DubaiSat 2 and STSAT-3. Delfi was one of 25 secondary payloads aboard the rocket, for a total of 32 satellites; the most deployed by a single rocket[6]

The Delfi team made contact with the satellite during its first pass.
