The picture was received on September 8. On that day, the lunar disk was illuminated by about 40%. The image was taken when the ISS flew over Oceanus Procellarum.

Oceanus Procellarum is a giant plain covered with basalt deposits left over from ancient eruptions. The territory it occupies exceeds 4 million km2, which is more than the area of India. 

According to some assumptions, Oceanus Procellarum was formed as a result of a powerful impact that occurred shortly after the formation of the Moon, when it was still covered by an ocean of magma or Oceanus just ceased to exist. The impact led to the release of a huge amount of matter, which settled on the far side of the Moon, forming the highlands covering it. As for the remaining giant crater, its rim and central peak were erased by subsequent impacts and volcanism.

As for the ISS, it was illuminated by the Sun at the time of the photo. Therefore, we can see its main modules and a hundred-meter truss structure on which solar panels are placed.

Earlier we talked about how Andrew McCarthy took an epic picture of the Milky Way.
