The Chang E-3 landing and working area selecting: Based on the lunar digital terrain model

摘要

This paper focuses on the landing region of Chang E-3 (the satellite that will soon be sent to the Moon by Chinese government in 2013). The topographical and thermal factors are considered in our addressing model. Regions with a relatively lower slope and shadowed by hills several times a day are thought to be much easier for satellites to land and work on because these kinds of regions have a proper surface temperature and lower moving difficulty. Through our calculation, a difficult level map is given for proper landing and working regions.
