Replay of the CubeSat separation coverage from Europe’s Spaceport in French Guiana. Three CubeSats took advantage of the Soyuz rocket carrying the Sentinel-1B satellite into orbit on 25 April 2016. These small satellites, each measuring just 10×10×11 cm, were developed by teams of university students through the ‘Fly Your Satellite!’ programme, run by ESA’s Education & Knowledge Management Office in close collaboration with European universities. The three CubeSats are: OUFTI-1 from the University of Liege, Belgium, e-st@r-II from the Polytechnic of Turin, Italy, and AAUSat-4 from Aalborg University, Denmark. The rocket also carried Microscope from the French space agency, CNES.
