(AP Photo/James Brooks)LONDON – A sled and flag used in one of explorer Ernest Shackleton's famed expeditions to the South Pole have been bought by a British government-funded body to keep the treasured artifacts in the U.K. The expedition was named Nimrod after the ship, which came within less than 100 miles (160 kilometers) of the South Pole for the first time in 1909. Shackleton never reached the South Pole and died of a heart attack in 1922 off South Georgia, a British overseas territory, during a fourth Antarctic expedition. The sled and flag were owned by Eric Marshall, a surgeon and polar explorer who accompanied Shackleton on Nimrod’s “sledge march” to the South Pole.

CAPE CANAVERAL, Fla. – A network of salty ponds may be gurgling beneath Mars’ South Pole alongside a large underground lake, raising the prospect of tiny, swimming Martian life. Italian scientists reported their findings Monday, two years after identifying what they believed to be a large buried lake. These ponds appear to be of various sizes and are separate from the main lake. The surface temperature at the South Pole is an estimated minus 172 degrees Fahrenheit (minus 113 degrees Celsius), and gets gradually warmer with depth. These bodies of water are potentially interesting biologically and "future missions to Mars should target this region," the researchers wrote.
