A dust storm similar to the Earth's dust is often formed in the Mars in the summer, which will lead to a sharp decline in solar energy. So a "sleep" mode must be designed for the Mars rover and let it wait patiently until the disappearance of dust storms.
火星在夏季常形成类似地球沙尘天气的尘暴，这会导致火星车接收的太阳光能量急剧下降，必须为火星车设计“休眠”模式，让其耐心地等待尘暴过去。
