More accurately, they don't have a thorough understanding of the terrain. If it encounters a hill on the first orbit then that'll be the orbit it impacts on.LURCH said:The uncertainty is because it is not a precise, targetted crash.
The purpose of sending a satellite to impact the Moon is to study its composition, structure, and history. By intentionally crashing a satellite into the Moon, scientists can collect data and analyze the debris to gain a better understanding of our closest celestial neighbor.
A satellite impacts the Moon by intentionally crashing into its surface at a high speed. This impact creates a crater and sends debris flying into the surrounding area. Scientists can measure the size and depth of the crater, as well as analyze the composition of the debris, to learn more about the Moon.
The type of satellite being used for the impact can vary, but it is typically a small, low-cost spacecraft specifically designed for this purpose. These satellites may have instruments or cameras onboard to collect data before impact and may also have a special coating to protect them from the extreme conditions of impact.
The impact of a satellite on the Moon will not significantly affect its orbit or cause any damage. The size of the satellite and the impact crater will be relatively small compared to the size of the Moon. However, the impact may create observable changes in the Moon's surface, which can provide valuable insights to scientists.
The satellite's impact on the Moon can provide valuable information about the Moon's composition, structure, and history. By studying the impact crater and debris, scientists can learn about the Moon's surface and subsurface, as well as its geological processes. This information can also help us better understand the formation and evolution of the Moon and other rocky bodies in our solar system.
