Vega flight VV02

Vega flight VV02 was the second flight of the Vega launcher. It occurred from the Guiana Space Centre on 7 May 2013 at 02:06:31UTC.
Payload
The flight was a multi-payload mission that deployed 3 satellites (2 Earth observation satellites and 1 educational CubeSat) into orbit, with a total payload mass of about including the satellites themselves (about 255 kg) and the satellites adapter and dispenser.
PROBA-V
PROBA-Vegetation, with a mass of , was in the upper position and was the first satellite to be separated, approximately 55 minutes and 27 seconds after liftoff. Its target was a quasi-circular sun-synchronous orbit at an altitude of and an inclination of 98.73°.
VNREDSat-1
VNREDSat-1, with a mass of , was in the lower position. Its target orbit was a quasi-circular sun-synchronous orbit at an altitude of and an inclination of 98.1°, to be deployed 1 hour, 57 minutes and 24 seconds after liftoff.
ESTCube-1
The Estonian Student Satellite-1 (ESTCube-1), with a 1U volume and a mass of , was the only CubeSat onboard Vega's second flight. It was accommodated in the lower position of the structure, and was deployed by the ISIPOD dispenser 3 minutes and 24 seconds after VNREDSat-1 in approximately the same orbit.
It operated for more than 2 years before contact was completely lost on 19 May 2015.
