Not only are they making low Earth orbit (LEO) space exploration more accessible due to cheap production, but they can be used in both commercial and amateur projects, making applications versatile. Originally, CubeSats were invented by researchers at California Polytechnic State University and Stanford University to “enable graduate students to design, build, test and operate limited capabilities of artificial satellites within the time and financial constraints of a graduate degree program,” Space Daily reported recently . This was accomplished by establishing a standard CubeSat dimension of 10x10x11 cubic units — small enough to speed up the process and ensure low costs.
