As expected, coming in a range of materials means that there is extensive flexibility with respect to colour choice. Throughout their history the Moon Boot has always been a bright and happy addition to any winter wardrobe and now is no different. Colour examples include neutral and subtle tones such as ochre, grey, dark brown, black and ice through to light pink, violet, azure, petrol blue, orange and sea green. More conspicuous colours consist of silver, ivory, burgundy, bouganville, apricot, red and yellow especially since some also come in a metallic finish. Each of the little Space eggs resides within its own ring arc--which is a fragmentary ring of Saturn. One hypothesis states that glittering ice crystals swarming around in the ring arc might be floating down to the surface of Methone, filling in its impact craters or other rough topography. This is something that is thought to have occurred on two other small, icy moons of Saturn--Atlas and Pan. Icy stuff swarming around in Saturn's rings apparently piled up around each moonlet's equator. This important measurement was made using Cassini's INMS instrument, which detects gases with the goal of determining their composition. INMS was designed to sample the upper atmosphere of Saturn's large, smoggy moon Titan. However, after Cassini's surprising discovery of a tall plume if icy spray erupting from cracks on Enceladus in 2005, planetary scientists turned its detectors to that small moon.
