The SunCube FemtoSats are exceptionally innovative and well-designed mini satellites, developed by a group of students over at Arizona State University, that is designed to make space travel a much more compact affair whilst also reaping significant savings, ultimately allowing greater access to the space exploration realm.
Each of these mini satellites is equipped with its own data collection, propulsion and communication systems and is powered by solar power. What's great about this mini satellite project is that the modules were made out of easily available off-the-shelf components. This proves that any university, lab or hobbyist group can make their own mini satellite.
Ultimately, this mini satellite project is bidding to make space science more accessible to people and groups who may not have the funds of your typical space agency.
