“凤凰”号肩负着在火星北极“探冰”和监测火星极地气候两大任务,预定降落在火星表面北纬65度至72度区域内,进行就地勘测,它的主要工作任务是什么呢?研究火星极地的气候、天气及其与地面的相互作用,分析北纬70度附近低空大气的成分,重点探测水、冰、尘粒、稀有气体和CO2,并在大气层下降过程中测量大气的特性:描述北部地区的地貌及地貌形成过程,测量表面下层土壤的物理特性、重点研究水的作用;测量水成矿物、土壤中的水分和有机成分:验证“奥德赛”关于近表面层有冰水的发现;了解水、冰和极区气候变化历史,研究过去和现在火星表面及表面下层环境中存在生命的可能性。
“Phoenix ” is shouldering the two tasks of “exploring the ice” and monitoring the polar climate of Mars on the North Pole of Mars. It is scheduled to land in the region of 65 to 72 degrees north latitude on the surface of Mars for on-the-spot investigation and its main tasks What is it? Studying the climate and weather of Mars and its interaction with the ground, analyzing the composition of the low-altitude atmosphere around 70 degrees north latitude, focusing on the detection of water, ice, dust particles, rare gases and CO2 and measuring during the descent of the atmosphere Atmospheric characteristics: Describe the geomorphology and geomorphology of the northern region, measure the physical properties of the underlying soils, and focus on the role of water; measure water-mineral and soil moisture and organic constituents: Validation “Odyssey” The discovery of ice and water; understand the history of climate change in water, ice and polar regions to study the possibility of existence in the past and present and the subsurface Mars environment.
