人类可望在20年后登上火星
People could land on Mars in the next 20 to 30 years provided scientists can find water on the red planet, the head of NASA's surface exploration mission said on September 16. Two partially solar-powered "robot geologists" -- Mars Exploration Rovers, or MERs -- have been trundling across 3 miles of the planet and into craters since January, beaming back data about the makeup of what scientists believe is Earth's sister planet. 只要能够找到水源,人类有望在20到30年后登上火星 9月16日,美国国家宇航局地表探测任务小组的负责人表示,如果科学家们能够在火星上找到水源,人类可能在20到30年后登上火星。
