The Earth’s moon has been an endless source of fascination for humanity for thousands of years. When at last Apollo 11 landed on the moon’s surface in 1969, the crew found a desolate, lifeless orb, but one which still fascinates scientist and non-scientist alike.
This image of the moon’s north polar region was taken by the Lunar Reconnaissance Orbiter Camera, or LROC. One of the primary scientific objectives of LROC is to identify regions of permanent shadow and near-permanent illumination. Since the start of the mission, LROC has acquired thousands of Wide Angle Camera images approaching the north pole. From these images, scientists produced this mosaic, which is composed of 983 images taken over a one month period during northern summer. This mosaic shows the pole when it is best illuminated, regions that are in shadow are candidates for permanent shadow.

July 20, 1969. “Houston, Tranquillity Base here. The Eagle has landed.” “One small step for man, a giant leap for mankind.”
Launched from Florida on July 16, the fifth manned mission, and the third lunar mission of NASA‘sApollo program, was crewed by Commander Neil Armstrong, Command Module Pilot Michael Collins, and Lunar Module Pilot Edwin “Buzz” Aldrin, Jr. On July 20, Armstrong and Aldrin landed in the Sea of Tranquillity and on July 21 became the first humans to walk on the Moon. Their landing craft, Eagle, spent 21 hours and 31 minutes on the lunar surface while Collins orbited above in thecommand ship, Columbia. The three astronauts returned to Earth with 47.5 pounds (21.5 kg) of lunar rocks and landed in the Pacific Ocean on July 24.
A very popular target with amateur astronomers, Tycho is located at 43.37°S, 348.68°E, and is about 51 miles (82 km) in diameter. The summit of the central peak is 1.24 miles (2 km) above the crater floor. The distance from Tycho’s floor to its rim is about 2.92 miles (4.7 km).
Tycho crater’s central peak complex, shown here, is about 9.3 miles (15 km) wide, left to right (southeast to northwest in this view).

A total lunar eclipse is seen as the full moon is shadowed by the Earth on the arrival of the winter solstice, Tuesday, December 21, 2010 in Arlington, VA. The eclipse lasted about three hours and twenty-eight minutes.
A lunar eclipse occurs when the Earth lines up directly between the sun and the moon, blocking the sun’s rays and casting a shadow on the moon. As the moon moves deeper and deeper into the Earth’s shadow, the moon changes color before your very eyes, turning from gray to an orange or deep shade of red.
