Earth's Moon, A Familiar Face

Earth's Moon, A Familiar Face

Explanation:
|
The above mosaic of the Earth's Moon [ http://seds.lpl.ari…] was compiled from photos taken by the spacecraft Clementine [ http://nssdc.gsfc.n…] in 1994. This image represents the side of the Moon familiar to Earth dwellers. The Moon [ http://www.c3.lanl.…] revolves around the Earth [ http://antwrp.gsfc.…] about once every 28 days. Since its rate of rotation about its axis is also once in 28 days, it always keeps the same face toward the Earth. As the Moon travels around its orbit, the Earth based view of the half of the Moon [ http://nssdc.gsfc.n…] that faces the Sun [ http://antwrp.gsfc.…] changes causing the regular monthly progression of Lunar phases. Humans first crashed a spacecraft [ http://nssdc.gsfc.n…] into the Moon in 1959, but the first humans to reach the Moon landed [ http://www.ksc.nasa…] in 1969. There are now golf balls [ http://ees5-www.lan…] on the Moon. Tomorrow's picture: Ganymede: Moonquake World
