The manned missions that NASA is preparing are destined for this region of the Moon .
The NASA has produced a simulation showing unusual movements of the Earth and the Sun as seen from the South Pole of the Moon , destination preparing manned missions agency.
The animation, posted on the NASA Godard YouTube channel , compresses three months (a little over three lunar days) into two minutes.
The virtual camera is on the rim of Shackleton Crater, partially visible in the lower right, and is pointing at Earth . The mountain on the horizon, some 120 kilometers away, is unofficially known as Mons Malapert.
Observing the Sun and the Earth
Here, the Sun glides around the horizon, never more than 1.5 degrees above or below it, while the Earth swings up and down, never deviating far from 0 ° longitude. The Earth appears to be upside down and spinning backwards.
The perpetually low angle of the Sun produces extremely long shadows that swirl across the rugged lunar terrain.
In the second month of visualization, the Earth passes in front of the Sun , creating an eclipse. For observers on Earth , this is a lunar eclipse, in which the Moon passes through the shadow cast by Earth . However, as seen from the moon , this is an eclipse of the sun .
