ESA Science & Technology - Illustration of SMART-1 mapping the Moon

In addition to a technology payload (comprising KaTE, SPEDE and EPDP), the SMART-1 spacecraft carried a science payload of three remote-sensing instruments:

• The Advanced Moon micro-Imager Experiment (AMIE): a multicolour camera which provided images (in white light and in three filters: 750 nm, 900 nm and 950 nm) that were used to set the geological context for measurements taken by the other two instruments, and to study the lunar poles;
  
  
• the SMART-1 InfraRed Spectrometer (SIR), operating in the 0.9 - 2.6 µm range, which carried out a mineralogical survey of the lunar crust;
  
  
• D-CIXS (Demonstration of a Compact Imaging X-ray Spectrometer), which performed the first lunar X-ray fluorescence mapping - in the 0.5-10 keV range - of the elemental composition of the Moon, with support calibration by the X-ray Solar Monitor (XSM).
  
  

The image above depicts how the science instruments scanned the lunar surface during a pass; repeated passes during the mission lifetime gradually completed the coverage.
