An abundant source of energy in space, electromagnetic radiation can provide spacecraft with a gentle yet persistent thrust for interplanetary and interstellar missions. Early successes with microlaser and solar propulsion platforms confirm their potential for near-Earth and deep space exploration, although practical realization of reliable photonic devices is not trivial. This Perspective outlines the recent achievements and future outlook in the field of photonic space propulsion. 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. Finally, we outline some of the key challenges in the area and possible solutions for practical applications.

光子空间推进的前景和物理机制

电磁辐射是太空中丰富的能源,可以为航天器提供平稳而持久的推力,以执行行星际和星际任务。尽管可靠实现光子器件的实际实现并非易事,但微激光和太阳推进平台的早期成功证实了其在近地和深空探测中的潜力。该观点概述了光子空间推进领域的最新成就和未来展望。我们重点介绍了几种通过光子-物质相互作用产生推力的光致机理,例如光子压力和烧蚀,光学梯度力,光诱导的电子发射等。最后,我们概述了该领域的一些关键挑战以及实际应用的可能解决方案。
