On comet 67P, VIRTIS observes surface water ice mixed with a non-ice organic rich refractory component, in a region were the localized water activity occurs. Moreover, the ice signature is variable with time and illumination conditions suggesting a cyclic process of sublimation-condensation of water ice on the comet surface. The cyclic replenishment of ice, due to the illumination changes, in the first comet layers can be the key for the strong local activity at such high heliocentric distance.
