The first lunar exploration vehicles of the 1950s were primitive pioneers. But aerospace technology developed so rapidly that only about a decade separated the first flyby forays and Nell Armstrong’s history-making steps on the moon surface.
The Moon is the only natural satellite of the Earth and the fifth largest moon in the Solar System. It is the largest natural satellite of a planet in the Solar System.
The moon can always be seen bright from Earth, and the same face is always turned towards the Earth. The moon in fact is actually exceptionally dark, and has a similar reflectivity to coal. It appears white in comparison to the darker sky around it.
