This　paper　decribes　the　method　of　mission　planning　for　planetary　rover.　Based　on　differences　and　relationships　between　mission　planning　and　path　planning,　path　planning　method　used　in　mission　planning　is　described　briefly　at　first.　Then　focus　on　the　constraints　in　mission　planning　and　strategies　to　deal　with　it,　including　time,　resource　and　communication.　Control　of　solar　panel　to　realize　effective　charging　and　control　of　directional　antenna　to　communicate　with　ground　station　are　discussed.　In　the　end,　the　simulation　of　planning　in　virtual　reality　environment　is　shown.　The　simulation　result　proves　the　effectiveness　of　the　method.　The　content　in　this　paper　would　contribute　to　further　researches　and　implementation　in　planetary　exploration　project.　©　2011　IEEE.
