ESA's OPS-SAT is a Swiss army knife in orbit. The 30-cm CubeSat packs a powerful onboard computer and an array of instruments that make it the ideal laboratory for testing innovative new technologies in space.

Thanks to the ESA Discovery programme, 12 new experiments will be doing just that, as they develop software, concepts and protocols that push the robust CubeSat to its limits and that could one day be essential parts of future spacecraft missions.
