The first picture of the Earth from lunar orbit
• The first picture of the Earth from lunar orbit
50 years ago, NASA's unmanned spacecraft "Lunar Orbiter 1" took the first picture of the Earth from the Moon's orbit.
"Lunar Orbiter 1" - the first automatic machine in the program, launched with the purpose of reconnoitering the lunar surface and determine the possible landing site for manned spacecraft "Apollo".
August 10th a 385-pound probe was launched from Cape Canaveral and, despite some difficulties with navigation and overheating, over 92 hours has reached lunar orbit.
August 18 began mapping the lunar surface by fotoustanovki consisting of two lenses: Xenotar 80 mm wide-angle lens for shooting medium resolution and 610mm telephoto Paxoramic for shooting with high resolution.
During mapping of the lunar surface, NASA rose an unexpected question: why not try to point the camera to the Earth?
The original plan did not provide for this maneuver, so the ship's movement could potentially lead to irreversible consequences. But the opportunity was so tempting that abandon it failed.
August 23, 1966 in 1198 km above the surface of the moon spacecraft "Lunar Orbiter 1" turned and fired the first shot of the Earth above the lunar orbit. Two days later, he took the second frame.

Despite the vagueness and spotted by bands, because of the technological limitations of the time, this unprecedented image allowed mankind to first look at the Earth from another celestial body.
"Lunar Orbiter 1" successfully fulfilled the goals, having worked for 80 days since the launch, and then made a crash-land on the lunar surface. From 1966 to 1967, NASA launched four more automatic orbiters mapping of the lunar surface. Space probes photographed 99% of the surface of the Moon.
Decades later, a group of NASA employees began a review of the old film photography. In 2008, a project to restore and digitize images from the program "Lunar Orbiter" (Lunar Orbiter Image Recovery Project), presented a stunning new version of the first image. In modern processing revealed previously unnoticed detail frame.
