Salty water just below the surface of Mars could hold enough oxygen to support the kind of microbial life that emerged and flourished on Earth billions of years ago, researchers reported last Monday.科学研究工作人员上星期一汇报称作,火星土层下的食盐水有可能有着必须维持微生物生命的充足co2,而这种微生物曾在十亿年以前在地球上子孙后代生存。In some locations, the amount of oxygen available could even keep alive a primitive, multicellular animal such as a sponge, they reported in the journal Nature Geosciences.据科学研究工作人员公布发布在《大自然地球科学》杂志期刊上的汇报,在一些地区,氧气含量乃至低约可保持详细多体细胞的生物的生命的水准,如海绵动物。

We discovered that brines — water with high concentrations of salt– on Mars can contain enough oxygen for microbes to breathe, said lead author Vlada Stamenkovic, a theoretical physicist at the Jet Propulsion Laboratory in California.美国加州的喷气式飞机前行试验室的基础理论科学家弗拉约·萨图门米哈伊洛维奇答复:“大家寻找,火星上的卤汁(浓度较高的食盐水)中常含够微生物大便的co2。”This fully revolutionizes our understanding of the potential for life on Mars, today and in the past.“此寻找基本上变化了大家对火星有可能不会有生命的了解,不论是之前的還是如今的了解。

”Up to now, it had been assumed that the trace amounts of oxygen on the Red Planet were insufficient to sustain even microbial life.直到现在,大伙儿依然都强调,火星上平流层co2没法维持微生物的生命。We never thought that oxygen could play a role for life on Mars due to its rarity in the atmosphere, about 0.14 percent, Stamenkovic said.萨图门米哈伊洛维奇答复,“因火星空气中氧气含量大概为0.14%,十分平流层,因此 大家未曾要想过这一点co2能够让生物生存。

”By comparison, the life-giving gas makes up 21 percent of the air we breathe.比较之下,地球大气中氧气含量为21%。
