“毅力号”至今已采集了多份宝贵的岩石和土壤样本，其中包括一些带有类似“豹纹”和“罂粟籽”状有趣特征的样本（科学家怀疑这可能是远古微生物活动的证据）。这些样本被仔细封装在约 30 个雪茄形状的采样管中，静待未来由 NASA 规划的复杂“火星样本取回”（Mars Sample Return）任务将其带回地球进行深入分析。但这...
Back in July 2020, for example, the maximum total cost of the Mars sample return (MSR) campaign — a collaboration between NASA and theEuropean Space Agency(ESA) — was estimated to be around $3 billion. But just three years later, the expected price tag had risen to $8 billion...
据外媒报道，NASA近日又创造了一项新的纪录：降落伞充气速度最快。这一里程碑由Mars 2020降落伞完成，它已于上月月初在地球大气并通过Black Brant IX探空火箭进行了测试。据悉，这一纪录具体创造时间则是2018年9月7日，这是Mars 2020降落伞测试的其中一部分内容。带有降落伞的有效载荷在从地球发射2分钟后就与火箭分...
NASA designing suits for Mars.The space agency is about to drop its unmanned Curiosity rover on the red planet. But some are looking ahead with hopes of sending humans there. NASA is testing a prototype Z-1 spacesuit, which is much more advanced than 20-year-old designs used now. The ...

NASA计划通过Mars 2020任务收集火星土壤样本 并将其带回地球 据外媒BGR报道，如果一切按计划进行，美国宇航局（NASA）的“Mars 2020”任务肯定会成为创纪录的记录。被送到火星的漫游车将能够执行火星上其他机器无法执行的任务，这意味着许多令人振奋的发现即将来临。例如，Mars 2020将收集火星土壤的样本，NASA最终会将其...
美国宇航局(NASA)的工程师已在Mars 2020火星车上安装了一个关键设备,用于收集、密封和最终返回地球的红色星球土壤样本。加州帕萨迪纳喷气推进实验室的工程师已经安装了样品缓存系统的位旋转传感器,用于存储和分类核心样品的工具和容器,以及在火星车内移动它们进行处理。 自1976年第一个“维京号”探测器降落在火星上以来...
"But it wasn't always that way," he said. "For reasons that are not yet known, prior to about three-and-a-half billion years ago, Mars' climate was very different, there was clearly flowing water on the surface of the planet. As we currently understand life, it requires liquid water...
