A unique view of Earth, as seen from the moon

When I saw this amazing photo of our water planet, I knew I had to share it with readers of this blog. NASA is offering a high-resolution image (click to enlarge) on its website.

The composite photo was taken from NASA’s Lunar Reconnaissance Orbiter, which orbits the moon and can see the Earth rising and setting above the moon’s horizon.

“The image is simply stunning,” said Noah Petro, deputy project scientist for LRO at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The image of the Earth evokes the famous ‘Blue Marble’ image taken by Astronaut Harrison Schmitt during Apollo 17, 43 years ago, which also showed Africa prominently in the picture.”

His comments and other information are provided in a NASA news release.

LRO experiences 12 Earthrises every day, but its instruments are normally focused on the lunar surface. Images of Earth are captured rarely when LRO’s camera is turned away from the moon to study the extremely thin lunar atmosphere or to make calibration adjustments, according to the news release, which explains the entire process.

The image above was composed from a series of photos taken Oct. 12, when the spacecraft was about 83 miles above the farside of the moon.

Astronauts on the moon can never see the Earth rise or set. Since the moon revolves around its axis at the same rate as its rotation around the Earth, it always appears in the same spot in the moon’s sky. That location varies by where the observer is standing on the moon’s surface, and there is no Earth visible from the farside of the moon. Where the Earth is visible, the view of the planet is constantly changing, as continents rotate into view — unlike the view of the moon’s surface from Earth, which never changes.

NASA’s first Earthrise image was taken with the Lunar Orbiter 1 spacecraft in 1966. Perhaps NASA’s most iconic Earthrise, according to NASA, was taken by the crew of Apollo 8 on Christmas Eve in 1968.
