ESTCube-1 is the first Estonian satellite and first satellite in the world to attempt to use an electric solar wind sail (E-sail). It was launched on 7 May, 2013, aboard Vega VV02 carrier rocket[3][4] and successfully deployed into the orbit.[5] The CubeSat standard for nanosatellites was followed during the engineering of ESTCube-1, resulting in a 10×10×11.35 cm cube, with a volume of 1 liter and a mass of 1.048 kg.[6][7]

The mission ended officially on 17 February, 2015, and it was said that during this time it resulted in 29 bachelor's and 19 master's dissertations, 5 doctoral theses and 4 start-ups.[8] The deployment of the E-sail tether was unsuccessful, and thus no measurements were taken of the E-sail or of the plasma braking deployment system.[9] The last signal from ESTCube-1 was received on 19 May, 2015.
