The New Moon in the Old Moon s Arms
Explanation: Also known as the Moon's ashen glow,
Earthshine is Earthlight illuminating the Moon's night side. Taken on
Nowruz, the March 20 equinox, from Esfahan, Iran, planet Earth, this telescopic image captures strong Earthshine from an
old Moon. The darker earthlit disk is in the arms of a bright sunlit crescent. But the
view from the Moon would have been enchanting too. When the Moon appears in Earth's sky as a slender crescent, a dazzlingly bright, nearly full Earth would be seen
from the lunar surface. The Earth's brightness due to reflected sunlight is known to be strongly influenced by cloud cover. Still, a description of Earthshine, in terms of sunlight reflected by Earth's oceans in turn illuminating the Moon's dark surface, was written 500 years ago by
Leonardo da Vinci.

Could a similar picture be done with HDR so that the moon's features within the crescent would not be washed out?

The Moon was but a Chin of Gold_
by
Emily Dickinson
A Night or two ago—
And now she turns Her perfect Face
Upon the World below—
Her Forehead is of Amplest Blonde—
Her Cheek—a Beryl hewn—
Her Eye unto the Summer Dew
The likest I have known—
Her Lips of Amber never part—
But what must be the smile
Upon Her Friend she could confer
Were such Her Silver Will—
And what a privilege to be
But the remotest Star—
For Certainty She take Her Way
Beside Your Palace Door—
Her Bonnet is the Firmament—
The Universe—Her Shoe—
The Stars—the Trinkets at Her Belt—
Her Dimities—of Blue—
<<The first student selected photos of the Moon’s surface snapped by NASA’s new pair of student named Lunar Mapping orbiters – Ebb & Flow - have just been beamed back and show an eerie view looking back to the Home Planet – and all of Humanity – barely rising above the pockmarked terrain of the mysterious far side of our nearest neighbor in space. The student photo is reminiscent of one of the iconic images of Space Exploration – the first full view of the Earth from the Moon taken by NASA’s Lunar Orbiter 1 back in August 1966.
The images were taken in the past few days by the MoonKAM camera system aboard NASA’s twin GRAIL spacecraft currently circling overhead in polar lunar orbit, and previously known as GRAIL A and B. The formation-flying probes are soaring over the Moon’s north and south poles. The nearly identical ships were rechristened as Ebb and Flow after Fourth grade students from the
Emily Dickinson Elementary School in Bozeman, Mont., won the honor to rename both spacecraft by submitting the winning entries in a nationwide essay competition sponsored by NASA. “The Bozeman 4th graders had the opportunity to target the first images soon after our science operations began,” said Maria Zuber, GRAIL principal investigator of the Massachusetts Institute of Technology in Cambridge, Mass., to Universe Today. It is impossible to overstate how thrilled and excited we are !”
GRAIL’s science goal is to map our Moon’s gravity field to the highest precision ever. This will help deduce the deep interior composition, formation and evolution of the Moon and other rocky bodies such as Earth and also determine the nature of the Moon’s hidden core. Engaging students and the public in science and space exploration plays a premier role in the GRAIL project. GRAIL is NASA’s first planetary mission to carry instruments – in the form of cameras – fully dedicated to education and public outreach.
Over 2,700 schools in 52 countries have signed up to participate in MoonKAM.
4th Grade Students from Bozeman, Montana (inset) won NASA’s contest to rename the GRAIL A and GRAIL B spacecraft and also chose the first lunar targets to be photographed by the onboard MoonKAM camera system. 5th to 8th grade students can send suggestions for lunar surface targets to the GRAIL MoonKAM Mission Operations Center at UC San Diego, Calif. Students will use the images to study lunar features such as craters, highlands, and maria while also learning about future landing sites.
NASA calls MoonKAM – “The Universe’s First Student-Run Planetary Camera”. MoonKAM means Moon Knowledge Acquired by Middle school students. The MoonKAM project is managed by Dr Sally Ride, America’s first female astronaut. “What might seem like just a cool activity for these kids may very well have a profound impact on their futures,” Ride said in a NASA statement. “The students really are excited about MoonKAM, and that translates into an excitement about science and engineering.” “MoonKAM is based on the premise that if your average picture is worth a thousand words, then a picture from lunar orbit may be worth a classroom full of engineering and science degrees,” says Zuber. “Through MoonKAM, we have an opportunity to reach out to the next generation of scientists and engineers. It is great to see things off to such a positive start.”
Altogether there are eight MoonKAM cameras aboard Ebb and Flow – one 50 mm lens and three 6 mm lenses. Each probe is the size of a washing machine and measures just over 3 feet in diameter and height. Snapping the first images was delayed a few days by the recent series of powerful solar storms. “Due to the extraordinary intensity of the storms we took the precaution of turning off the MoonKAMs until the solar flux dissipates a bit,” Zuber told me. “GRAIL weathered the storm well. The spacecraft and instrument are healthy and we are continuing to collect science data.”
The washing-machine sized probes have been flying in tandem around the Moon since entering lunar orbit in back to back maneuvers over the New Year’s weekend. Engineers spent the past two months navigating the spaceship duo into lower, near-polar and near-circular orbits with an average altitude of 34 miles (55 kilometers) that are optimized for science data collection and simultaneously checking out the spacecraft systems.>>

I thought the saying was: "The Old Moon in the New Moon's Arms", since the crescent new Moon looks like two outstretched arms.

The libration point on this day was pretty far to the SE (about 6 degrees south, 4.25 degrees east, 7.5 degrees at phase angle 214) making the SE features of the moon unusually visible! Good views of Mare Marginis and Mare Smithyii, (out past Mare Crisium area), and even Mare Australis (way, way out past Mare Nectaris).

Ahh Leonardo, you stick your nose in everything. Bet you were a pain in the behind 8th grader.

Kinda wondering what's with the "planet Earth" in the description. Unless there are some people who don't know that Iran is a country in Asia on planet Earth, or if there are aliens that don't know about Iran, I don't understand why that was added on.

Oh, good; I was wondering how I was going to get to work these next few months, but see Otto can manage the job quite nicely! Yay!

I hope you're well versed in the language of Gort, or you could be in B-i-g trouble
