Which moon is this?
Our Moon's unfamiliar appearance is due partly to an
unfamiliar viewing angle as captured by a little-known spacecraft --
the Soviet Union's
Zond 8 that circled the
Moon in October of 1970.
the dark-centered circular feature that stands out near the top of the image is
a massive impact basin formed by an ancient collision with an
is surrounded by light colored and highly textured highlands.
Across the image bottom lies the dark and expansive
the largest of the dark (but dry) maria that dominate the
side of the Moon
faces toward the Earth.
Originally designed to carry humans, robotic
came within 1000 km of the
lunar surface, took about 100
detailed photographs on film,
and returned them safely to Earth within a week.
