CubeSats are small, cheap satellites assembled from standardised parts in 10 cm boxes - M-Argo is a 12-unit CubeSat. Originally intended for educational purposes and technology testing, CubeSats have matured rapidly, and are becoming increasingly attractive to intuitional and commercial users for applications including Earth observation, telecommunications and even exploration.
Today hundreds of CubeSats are launched each year, while ESA employs them for early in-orbit demonstration of advanced technologies.
While CubeSats offer increasingly capable payload performance, their natural limits of size, mass and power typically preclude the inclusion of conventional spacecraft propulsion systems.
At the same time, such propulsion capabilities are crucial to enable mobility and to enhance the potential of CubeSats, which have started to utilise miniaturised chemical and electric propulsion.
This is the subject of a dedicated ESA workshop on Propulsion4CubeSats on 28-29 April. ESA's annual CubeSat Industry Days will follow in June.
