An abundant source of energy in space, electromagnetic radiation can provide spacecraft with a gentle yet persistent thrust for interplanetary and interstellar missions. Early success of micro-laser and solar propulsion platforms confirm their potential for near-Earth and deep space exploration, although practical realization of reliable photonic devices is not trivial. Motivated by an interest in space exploration, this brief report outlines the recent achievements in this young field. We highlight several light-enabled mechanisms of thrust generation via photon-matter interactions such as photonic pressure and ablation, optical gradient forces, light-induced electron emission and others, with potential technological impact in the contexts of space propulsion. Finally, we outline some of the key challenges and possible solutions for practical applications of these mechanisms, and propose a classification and guiding principles for future development of the field of photonic propulsion.
