Looking down the barrel of the Venus Monitoring Camera
Looking down the barrel of the Venus Monitoring Camera The Venus Monitoring Camera has four independent optical channels sharing one CCD. There is a VIS channel, with a spectral range of 503 to 523 nanometers; two near-infrared channels, with 900 to 970 and 990 to 1030 nanometer filters; and one UV channel, with a spectral range of 345 to 385. Most published VMC images employ the UV channel, because a mysterious substance in Venus' clouds that is dark in the ultraviolet helps us see wind motion. ESA / MPS
