[00:02.27]The most recent probe to be sent [00:04.29]was the Mars Odyssey launched in April 2001, [00:07.98]which is due to orbit the planet [00:09.52]and provide communications [00:10.96]for future explorations. [00:13.62]Another period of great interest in the planet [00:15.95]was caused by the finding of a small piece [00:18.18]of rock from Mars in Antarctica. [00:21.31]In 1996, the American space agency NASA [00:24.48]declared that there had been life on mars [00:27.22]in the form of tiny bacteria. [00:29.77]The claim was later dismissed [00:31.12]by other scientists, [00:32.67]but another study in 2001 confirmed [00:35.30]that the rock did contain chains of crystals [00:38.27]that could only be made by living things. [00:41.30]This has made people think again [00:43.08]about whether there is life on the planet now, [00:46.08]though not in the form of Martians [00:48.23]with big heads! [00:48.87]
