When the crawler pile driver is drilling, the current of the pile driver's ammeter shall not exceed 100A. If the ammeter current exceeds 100A, the drill pipe should stop and descend slowly, and the rotor always keeps turning. If the current drops below 100 amps and is stable, the drill pipe can continue to decline slowly.

Mars’ low atmospheric pressure also contributes to unique weather phenomena. The thin atmosphere allows for significant temperature fluctuations, with daytime temperatures at the equator reaching up to 20 degrees Celsius (68 degrees Fahrenheit) but plunging to -80 degrees Celsius (-112 degrees Fahrenheit) at night.
