“…The development of deep space exploration technology is of great help to mankind's understanding of major scientific issues such as the origin and evolution of life. Since the 1960s, the pace of human exploration of deep space has not stopped (Gong et al, 2020; Tang et al, 2010; Ye & Peng, 2006; Ye et al, 2018). The regolith of a planet contains abundant energy and resources and contains a variety of information about the planet.…”

“…The drawbacks of ground-based surveillance can be eliminated with a space-based platform. Space-based NEA surveillance systems have the advantages of flexibility, not limited by the atmosphere and weather, and large coverage [51]. Several space-based NEA surveillance missions have been carried out or planned, such as NEOWISE, NEOSSat, Arlkyd, NEOCam, and Earthguard-I [34,52,53].…”

“…Usually, one space-based surveyor (with the limited apparent visible magnitude equaling to 24) can only cover 60%-80% of NEAs (or PHAs) after years of detection and many of them are lost due to the phase difference [57]. Recently, the concept of NEA surveillance constellation has been proposed in order to improve overall efficiency and provide even more flexibility [51,58,59]. In this paper, we proposed a new concept of NEA surveillance constellation on the Venus-like orbit, the CROWN (constellation of heterogeneous wide-field NEA surveyors).…”

“…Due to the limitation of earth resources, asteroid exploitation and other space re-sources utilization have become a hot topic. Mineral resources on asteroids in space are good and abundant human resources that can be exploited and utilized [3]. Although there are many difficulties in exploiting the mineral resources of asteroids with existing technologies and funds, some countries are still trying and have made some gains.…”
