SOUTH POLE STOP
U.S. Navy Cmdr. Scott Shackleton arrives at the South Pole for a brief visit Feb. 9, 2010. Shackleton, a distant relative of the famous Antarctic explorer Sir Ernest Shackleton, is a Navy reservist assigned to the Military Sealift Command. He just wrapped up about two weeks at Antarctic research post McMurdo Station, where he was one of two cargo officers overseeing the offload of two of the command's ships that delivered fuel and supplies to the station.
