These views show the coverage of the Moon done by the Advanced Moon Imaging Experiment (AMIE) on board ESA's SMART-1 spacecraft during the first part (nominal mission) of lunar observations, in survey (or 'nadir') mode.
The top left panel shows the AMIE coverage during the commissioning phase; the top right panel shows the first coverage at medium-solar elevation; the bottom left panel shows the coverage at high solar elevation; the bottom right one shows the second coverage at medium solar elevation.
