William Anderson (naval officer) was distinguished. He was awarded the Bronze Star Medal and participated in a total of eleven combat submarine patrols. Anderson was selected by Admiral Hyman G. Rickover to be the second commanding officer of the first nuclear submarine to be placed into service, the USS "Nautilus" and was its commander from 1957 to 1959. Anderson and his crew received international notice when the "Nautilus" became the first submarine to sail successfully under the polar ice cap surrounding the North Pole. That transit was completed under direct orders of President Dwight Eisenhower, under extreme secrecy and was in direct response to
Ice cap climate Mountains, the Caucasus, and the Alps. Mars, like Earth, has ice caps at its poles. In addition to frozen water, Mars ice caps also have frozen carbon dioxide, commonly known as dry ice. In addition, Mars has seasons similar to Earth. The North Pole of Mars has a permanent water ice cap and a winter-only dry ice cap. On the south pole, both the water and carbon dioxide are permanently frozen. Europa, a moon of Jupiter, is covered with a permanent sheet of water ice, similar to Antarctica. Scientists theorize that it may have sub-glacial lakes similar to those seen
