U.S. space researchers say they have found more evidence that the planet Mars could have once been able to support life.
美國(guó)太空研究人員說(shuō)，他們發(fā)現(xiàn)更多證據(jù)顯示火星可能曾經(jīng)存在能夠維持生命的環(huán)境。
NASA scientists said Tuesday the Curiosity Mars rover found nitrates in Martian rocks. Nitrates are compounds that contain nitrogen, an element essential for life.
美國(guó)航空航天局的科學(xué)家們星期二說(shuō)，火星探測(cè)器“好奇號(hào)”在火星巖石中發(fā)現(xiàn)了硝酸鹽。硝酸鹽中含有氮，而氮是維持生命的必要元素。 But the scientists say there is no evidence the nitrogen came from living things and stress that the Martian surface cannot support any forms of life. 但科學(xué)家們說(shuō)，沒(méi)有證據(jù)顯示火星上的氮來(lái)自生物，并強(qiáng)調(diào)火星表面不能維持任何形式的生命。 They believe the nitrates are ancient and probably came from meteorites or lightning strikes. 科學(xué)家們相信，火星上的硝酸鹽存在已久，很可能來(lái)自流星或閃電。 This is not the first sign that the planet may have at one time been habitable. Past discoveries show signs that fresh water once covered the Martian surface. 目前還沒(méi)有跡象顯示火星可能曾經(jīng)適于居住。過(guò)去發(fā)現(xiàn)，火星表面曾被淡水覆蓋。
