Mars landers have been able to land only within tens to hundreds of km of a target site due to uncertainties in approach navigation, atmospheric modeling, and vehichle aerodynamics; as well as due to map-tie error and wind drift. The Mars Science Laboratory mission will improve this to 5-10 km using optical navigation and entry guidance. To achieve "pinpoint landing" (within 100m) for future missions, ways of addressing the remaining error sources must be found.
