ESA's SMART-1 spacecraft is using a new technique to reveal details on the surface of the Moon. The spacecraft has been taking a series of images, only seconds apart, with its Advanced Moon Imaging Experiment (AMIE) instrument. The same location is imaged at different infrared wavelengths. Scientists back at ESA can then stack up the images to see the same spot on the Moon, imaged in all these different wavelengths, and notice any unusual features on the lunar surface.
