Ground-based observations of Martian relief may be possible when the Earth-Mars geometry is optimum and the observing conditions are near perfect. There is some evidence that detectable relief is present. Groundbased observations of Martian relief during the coming opposition will be optimum between 1 February and 1 March and between 1 June and 15 August 1967.
