Armstrong-Crater is a significant geological feature on the Moon, named in honor of Neil Armstrong, the first human to walk on the Moon. Here are some detailed insights about this lunar landmark:
Location and Characteristics
- Armstrong-Crater is located on the lunar near side at latitude 1.4°S, longitude 24.8°E.
- It has a diameter of approximately 5 kilometers and is relatively small compared to other lunar craters.
- The crater's depth is not well-documented, but it is typical for small craters to have a shallow depth relative to their diameter.
- Due to its size, Armstrong-Crater is not easily visible from Earth, requiring telescopic observation for identification.
Formation and Geological Context
- The crater was formed by an impact event, where an asteroid or comet collided with the lunar surface.
- Its age has not been precisely determined, but it appears relatively young due to the crispness of its rim and lack of significant degradation.
- The region around Armstrong-Crater is part of the Mare Tranquillitatis, where Apollo 11 landed, highlighting the historical significance of the area.
Naming and Significance
- Named by the International Astronomical Union (IAU) in 1970, Armstrong-Crater commemorates Neil Armstrong's contribution to space exploration.
- This naming reflects a tradition of honoring astronauts and other notable figures from space exploration by naming lunar features after them.
Exploration and Research
- There have been no specific missions dedicated to Armstrong-Crater, but it has been observed by various lunar orbiters like Lunar Reconnaissance Orbiter (LRO).
- Data from these missions have helped in mapping the Moon's surface and understanding its geological history, although Armstrong-Crater itself has not been a primary focus.
