这项新工作将帮助研究人员完善他们对古代火星大气 的估计。 The new work will help researchers refine their estimates of the ancient Martian atmosphere . 但是寻找现存生命迹象的另一种方法是测试火星大气 中的甲烷含量。 But another way of searching for signs of existing life is by testing the Martian atmosphere for methane. 华莱士指出光谱分析看不到火星大气 中存在水蒸气的迹象。 Among other things Wallace pointed out that spectroscopic analysis had shown no signs of water vapor in the Martian atmosphere . 理解火星大气 发生了什么,有助于理解任何行星大气的动态和演化。 Understanding what happened to the Mars atmosphere will inform our knowledge of the dynamics and evolution of any planetary atmosphere. . 在地表附近,氧气将由火星大气 提供,而在地表之下更深处,氧气来自于放射性衰变。 Near the surface the oxygen would be supplied by the Martian atmosphere , whereas farther below it would come from radioactive decay.
它是专门为在火星大气 中飞行而设计的,比地球薄100倍。 It is specifically designed to fly in the atmosphere of Mars , which is 100 times thinner than Earth's. 年6月,就在TGO开始监测火星大气 几个月后,一场巨大的沙尘暴席卷了火星。 In June 2018, just a few months after the TGO began monitoring Mars's atmosphere , a giant dust storm spread across the planet. 年,“好奇号”证实了火星大气 中位于甲烷季节性急剧增加的疑问图片。 In 2018, Curiosity also confirmed sharp seasonal increases of methane in the Martian atmosphere .到2018年初,重复穿过火星大气 应该将TGO的峰值高度拉到250英里左右。 By early 2018, the repeated passes through the Martian atmosphere should pull TGO's peak altitude to around 250 miles. 与此同时,TGO将继续监测火星大气 ,至少持续到2022年。 In the meantime, the TGO will continue to monitor Mars's atmosphere through at least 2022. 就算你把所有这些二氧化碳都放入火星大气 ,也不足以使这颗星球变暖,”贾科斯基说。 Even if all this can be brought back into the atmosphere of Mars , this will not be enough to heat the planet,” says Yakowski. 理解火星大气 发生了什么,有助于理解任何行星大气的动态和演化。 Understanding what happened to the Mars atmosphere will increase our knowledge of the dynamics and evolution of any planetary atmosphere. . 年,“好奇号”证实了火星大气 中存在甲烷季节性急剧增加的现象。 In 2018, Curiosity also confirmed strong seasonal increases in methane in the Martian atmosphere .他们现在怀疑,火星大气 中的甲烷智慧保留大约300年。 Sunlight is thought to destroy methane molecules in Mars's atmosphere over about 300 years. 研究人员发现,季节变化是驱动水蒸气在火星大气 中分布的关键因素。 The researchers found that seasonal changes were the key factors driving how water vapor was distributed in the Martian atmosphere .就在2003与2004年,有三个独立的研究团队宣布在火星大气 中发现甲烷。 In 2004, three different research groups independently announced the discovery of significant concentrations of methane in the atmosphere of Mars .研究人员发现,季节变化是驱动水蒸气在火星大气 如何分布的关键因素。 The researchers found that occasional changes were the key variables driving how water vapor was circulated in the Martian air . 我们初步的数值结果表明,带有蝉翅的火星蜜蜂可以在火星大气 中产生足够的升力。 Our preliminary numerical results suggest that a bumble bee with a cicada wing can generate sufficient lift to hover in the Martian atmosphere . 原子氧会影响其他气体逃离火星的方式,因此对火星大气 具有重要意义。 Atomic oxygen affects how other gases escape Mars and therefore has a significant impact on the planet's atmosphere . 按照计划,该项目将向火星表面发射四台小型探测器,用来研究火星大气 和内部结构。 The mission would send four identical small landers to the Martian surface in order to study the planet's atmosphere and interior.
