You are telling me.
A large saltwater lake seems to lurk under ice near Mars’ south pole. If confirmed, it would be the first body of liquid water ever detected on the red planet and a significant milestone in the quest to determine whether life exists there.
在火星的南极附近，一个大型咸水湖貌似被冰层掩埋。如果得到证实，它将是这颗红色星球上探测到的第一个液态水体，亦是火星生命探索之路上的重大里程碑。
“It’s a very promising place to look for life on Mars,” says Roberto Orosei, a planetary scientist at the National Institute of Astrophysics in Bologna, Italy. “But we do not know for sure if it is inhabited.” On Earth, similar “subglacial” lakes are home to microbial life.
“这是火星上一个非常有希望寻找到生命的地方，” 意大利博洛尼亚国家天体物理研究所的行星科学家罗伯托·奥罗西如此表示道。“但我们还不能确知火星是否有生物居住。” 在地球上，类似的“冰下”湖泊是微生物的家园。
A team of Italian researchers, led by Orosei, reported the discovery on July 25 in Science. They spotted evidence of the buried lake in radar data from the European Space Agency’s Mars Express spacecraft.
7 月 25 日，由奥罗西领导的意大利研究员小组在《科学》杂志上发表了这项发现。他们在雷达数据中发现了掩埋湖泊的证据，这些数据来自欧洲航天局的火星快车空间探测器。
Others say that the work is tantalizing but, like anything else in the controversial hunt for water on Mars, it needs more supporting evidence. “It’s not quite a slam dunk yet,” says Jeffrey Plaut, a planetary scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California, who has searched for water using data from Mars Express.
其他人表示，这次发现很吸引人，但是和其他争议性的火星寻水行动发现的东西一样，这项发现还需要更多的证据支持。“这还不是稳操胜券的事，” 加州帕萨迪纳美国国家航天局喷气推进实验室的行星科学家杰弗里·普劳特这样说道，他曾用火星快车空间探测器提供的数据探寻过水源。
If further studies confirm the existence of a lake, it could open new avenues for investigating Mars. Researchers have drilled into subglacial lakes on Earth and sampled the water for signs of microbes, while others are developing technologies to reach a buried ocean on Jupiter’s moon Europa. There are no ice-drilling missions currently slated for Mars—but the latest discovery could change how scientists think about exploring the planet.
如果进一步的研究能够证实火星上湖泊的存在，这将为研究火星开辟新的道路。研究人员已经钻孔探测过地球上的冰下湖泊，并对湖水进行了取样，以此判断是否存在微生物。同时，另一些研究者正在开发技术，以此来钻入木星卫星欧罗巴的掩埋海洋。目前还没有为火星安排的冰钻任务——但最新的发现可能会改变科学家对探索火星的看法。
