- NASA loses radio contact with the Mars Polar Lander moments before the spacecraft enters the Martian atmosphere. 年,在火星极地登陆者号宇宙飞船进入火星大气前的瞬间,美国航空航天局失去了与其的无线电联系。
- Hurtling into the Martian atmosphere, the craft were completely beyond the control of the team in Pasadena, California. 在着陆过程中，加州帕萨迪纳的制控人员对冲入火星大气的探测器完全是鞭长莫及。
- Dawn was just breaking.Because the Martian atmosphere is thin, the earth was still covered in darkness. 这时正是黎明时分，由于火星大气层非常稀薄，大地还是黑沉沉的一片。
- That's because any bacteria that may once have lived on the surface have long since been exterminated by cosmic radiation sleeting through the thin Martian atmosphere. 这是因为早期存在火星表面的细菌可能早就被轻易穿越稀薄的火星大气层的宇宙射线杀死了.
- Frozen water is known to exist in the planet's polar regions, and water vapor has been detected in the Martian atmosphere. 已经知道有固态水在这颗行星的极地区域存在，水蒸汽也已经在火星大气中发现。
- Hanford and Long first set up a virtual "box" filled with about 10 million carbon dioxide molecules floating about randomly, at the same density as the Martian atmosphere. 多数模拟声音传播的数值模式，把介质视为连续体来处理：不去考虑分子个别行为的影响，只以整体的平均性质来做计算。
- All dust storms on Mars, no matter what size, are powered by sunshine. Solar heating warms the martian atmosphere and causes the air to move, lifting dust off the ground. 不管规模大小的火星尘暴,其动力都是太阳光。太阳照射使火星大气升温,引起空气流动,并将尘埃带离地面。
- Over the last year three teams, one using instruments on the Mars Express orbiter and two using ground-based telescopes, say they have detected methane in the Martian atmosphere. 去年，一组使用“火星特快”探测器，及另外两个通过地面望远镜进行观测的团队，都表示他们在火星大气中发现了甲烷。
- Although the Martian atmosphere is very rare,a parachute is an important decelerator in the entry,descent and landing system for Mars exploration mission. 尽管火星表面大气非常稀薄,但降落伞仍是火星探测着陆系统中一种重要的减速装置。
- The oxidant would also accelerate the loss of methane locally from the atmosphere, thus requiring a larger source to explain the abundances observed in the Martian atmosphere. 而且它是强氧化剂，会局部加速大气中甲烷的流失，因此需要更大的来源解释在火星大气中观测到的含量。
- Apparent tributaries near the bottom bolster the leading hypothesis that water gushed out of the crater wall, flowed down the crater, and soon evaporated into the thin Martian atmosphere. 外表看上去似乎存在地下支流，地下水从火山中涌出，沿着火山往下流淌，很快地就被蒸发到稀薄的火星大气中，这就是现在的主流假设。
