Multispectral views of Giordano Bruno from M3
These images of the fresh crater Giordano Bruno were all created with data from the Moon Mineralogy Mapper (M3 or "M-cubed") on India's Chandrayaan-1 orbiter. They are all false-color images representing information about the reflectance of lunar materials in the infrared portion of the spectrum. Left image: red channel is 930 nm, green channel 1249 nm, blue channel 2018 nm. Mafic minerals appear green to yellow; feldspar-rich pixels appear pink; mature regolith appears gray. Center image: red channel is 930 nm, green channel is 2018 nm, blue channel is 2816 nm. In this image, hydration features are highlighted yellow. Right image: A "rock type composite" that uses spectral band information to highlight certain minerals. The red channel highlights the spectral presence of pyroxene; the green channel, spinel; and the blue channel, anorthosite.
