1 Humans have detected Mars 45 times, but only 18 times, the success rate is only 40%; 2 every 26 months, there will be a transmitter meeting, otherwise it will not reach Mars; 3 Mars is far away from the Earth, the detector will fly hundreds of millions It takes only a kilometer to reach, and it has high requirements for launching, control, communication, etc. 4 It is very difficult to land Mars. Many Mars probes are at a loss at this stage.
①人类探测火星已有45次,但成功的只有18次,成功率仅40%;②每26个月才有一次发射机会,否则到不了火星;③火星距离地球遥远,探测器要飞几亿千米才能到达,对发射、控制、通信等技术要求很高;④着陆火星的难度非常大。许多火星探测器都在这一阶段功亏一篑。
