Recently Published Special Issue Magazine Article on CubeSats
For satellites, it used to be that dreams and big visions turned to reality after many years of development and many millions of dollars. This is no longer the case. CubeSats, a miniature-size satellite, offer an interesting paradigm shift that completely changes the design process for satellites, providing a relatively inexpensive access to space. For the traditional, expensive, and large satellites, the design goals often focus on making an extremely robust, high-performance satellite desi...
