Part 5/8:

The lunar module's descent engine had a limited maximum thrust of around 10,000 pounds. However, during the final landing phase, this was reduced to about 30% throttle, resulting in roughly 3,000 pounds of thrust—significantly less than engines like those found in helicopters that can produce around 15,000 pounds but fail to leave large craters on the ground.

When considering the dynamics of the lunar landing, it’s essential to note how rocket exhaust behaves. At sea level, exhaust forms a narrow jet due to ambient pressures. Once in a vacuum, where there is minimal resistance, the exhaust can spread out—reducing pressure at the exit and leading to less force exerted on the lunar surface.
