The Moon has held the imaginations of the human beings
since the advent of the modern world. However, it is the only
in the modern times that the humans have visited the lunar
surface. Initially, this was achieved by the robotic machines and
then it was achieved by the astronauts. The exploration of the
moon and the landing of the humans on its surface have
taught the humans much about the evolution of the Solar
System and life on Earth. The humans have known for
centuries about the effect on the biological cycles and tides
from the waning and waxing Moon. But it had taken the
space-age exploration and the landing of the Moon has
revealed the connection of the existence of the human beings
on a very fundamental level.
