SMART-1 Mission to the Moon: Technology and Science Goals

AMIE

Fig.6 AMIE camera optical and unit detector unit

The micro camera AMIE (Josset et al 2003) will provide high-resolution CCD images of selected lunar areas (Table 5 lists the broad objectives of the camera). It includes filters deposited on the CCD in white light + three filters for colour analyses, with bands at 750 nm, 900 nm and 950 nm. These will provide data on the 1 mm absorption of pyroxene and olivine. The camera will have an average resolution of 80 m/pixel, and 30 m/pixel near a 300 km the perilune. AMIE images will provide a geological context (Figures 9 & 10) for SIR and D-CIXS data, and colour or multi-phase angle complement (Muinonen et al 2002). Lunar south pole (Figure 8) repeated and deep high resolution images will be obtained. This will allow the identification of shadowed or double-shadowed areas, the search for potential 'water ice traps' or 'cold traps'. Also, SMART-1 will map potential sites of 'eternal light' and 'eternal shadow' or sites relevant for future lunar exploration (lunar bases, power supplies).

The AMIE camera will take high-resolution images to study the illumination properties of the lunar south polar region during the 6 month lunar science phase. AMIE will be able to map the interior of dark craters, taking targeted exposures deeper than those from the Clementine instruments.

The AMIE camera will provide the geological and spatial context for the other SMART-1 instruments, delivering high spatial resolution (30 m/pixel) multicolour images, as well as stereo imagery for topographic studies or multi-phase angle observations.
