The development of technologies that enable operational capabilities that broaden the range of missions carried out by CubeSats has recently been the focus of governmental and private actors in the field of small satellites. The examination and observation of larger spacecraft (like the International Space Station) or debris is a useful example of a new small-sat mission. In this context, a TDE study developed the Space Rider Observer Cube (SROC) mission, which attempts to demonstrate the critical capabilities and technologies needed to successfully carry out an inspection mission in a safety-sensitive environment. This in-orbit demonstration could pave the way for a variety of cutting-edge CubeSat applications in the field of inspection missions.
