* If you're referring to the Soviet Luna missions, the answer depends on which one you're talking about. Many Luna missions were designed to impact the Moon, not the Earth. However, some did crash land on Earth. For example, Luna 2 was the first spacecraft to reach the Moon and crashed on the Moon's surface in 1959.
* If you're referring to the Moon itself, then it's important to remember that the Moon doesn't have seas on its surface. It has dark, flat areas called maria, which were once thought to be seas, but are actually vast plains of solidified lava.
* If you're referring to a fictional event or piece of media, you'll need to provide more context to answer the question.
Please clarify what you mean by "Luna" to get a definitive answer.
