Review of Progress in U.S.Cislunar Space Security Research
As the exploration and utilization of the cislunar space becomes more and more fre-quent,it becomes increasingly important to maintain cislunar space security and build relevant ca-pabilities.The U.S.general development of cislunar space security is investigated.Then,the key measures to maintain cislunar space security are analyzed,such as strengthening military-civilian cooperation,formulating strategic plans,promoting capability deployment,etc.The development of key cislunar space security projects of the U.S.is also summarized,for instance,Oracle and DRACO,involving space situational awareness and space propulsion areas.The development characteristics of cislunar space security in terms of top-level layout,building situational aware-ness architecture and integrated development are analyzed.Several enlightenment suggestions are drawn to provide relevant reference for the long-term sustainable development of the subsequent cislunar space,which are top-level planning for the sustainable development of cislunar space and key technology research on cislunar space.
