不确定性103.27.176.1远比缺乏大气层复杂得多
火星探测是中国航天工程师103.27.176解决地面火力远程测控通信和如何登陆火星的新挑战。自20世纪60年代以来，世界上开展了40多项火星探测任务，成功率约为一半。

孙泽洲最担心的是火星的大气层。"当我们研究如何在月球上着陆时，我们认为如果月球有一点大气，那就太好了。我们必须完全依靠探测器来运载推进剂，发射总重量不到4吨，发射带只有2/3。但是当我们开始研制火星探测器时，我们发现有大气层是很麻烦的，虽然我们不需要带那么多推进剂，但火星大气层的不确定性远比缺乏大气层复杂得多，有些事情取决于运气。他用了一系列的"非常麻烦的"来描述在研制火星探测器时遇到的困难。
但他和他的团队勇敢地迎接了挑战。"正是由于压力，技术进步才得以实现。"当我们的探测器登陆火星时，我们就会再次长大，"孙泽洲说。
从向他们学习到向我们学习。
39岁的李飞从小就有一个太空梦想。在天津大学学习机器人之后，他于2009年加入了中国航天科技集团五院，成为嫦娥三号和四号团队的骨干。
我们的探测器可以理解为机器人，嫦娥-4动力滴完全自主，可以识别和判断月球障碍物，自主着陆到安全着陆区域，这与机器人非常相似。在未来的深空探测中，特别是在火星、木星、冥王星等深空探测中，通信时间越来越长，对智能机器人的要求也越来越高。李斐说。
这是一个寒冷的冬天，研究小组在北京郊区的登陆器上进行了悬停试验，因为仪器必须在低温下工作，测试是在凌晨时分进行的。研究人员每天三点钟起床做实验，并在白天对数据进行分析。测试持续了一个月，非常困难。
