The levels of gray in the image are gradually adjusted, saturating the background until the features of the landscape disappear. At that point, it\u2019s possible to see the edge of the total solar eclipse. As the gray levels are restored, the umbra, or the completely shadowed area, becomes visible, followed by the penumbra, or partial shadow where part of the Sun peaks over the edge of the Moon.LRO\u2019s Narrow Angle Camera can record 3600 gray levels, whereas most digital cameras record only 255 levels of gray. The camera was designed this way because the Moon is a high-contrast target, with very bright materials next to dark materials. In these images, those 3,600 levels of gray were squeezed into 255 levels because that\u2019s what a typical computer screen is capable of displaying. <br><\/div><div class=\"hds-credits\">Credits: NASA \/ Goddard \/ Arizona State University<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>The Narrow Angle Camera is part of the Lunar Reconnaissance Orbiter Camera system. Two Narrow Angle Cameras capture high-resolution black and white images, and a third, the Wide Angle Camera, captures moderate-resolution images using filters to provide information about the properties and color of the lunar surface. <\/p>\n\n\n\n<p>The Narrow Angle Camera builds up an image line by line rather than the more typical \u201cinstantaneous\u201d framing that occurs with digital or cell-phone cameras. Each line of the image is exposed for less than one-thousandth of a second; the exposure time was set as low as possible to prevent bright clouds from saturating the sensor. It takes about 18 seconds to acquire all 52,224 lines for the image.<\/p>\n\n\n\n<p>While the thrill of the total eclipse was in experiencing the shadow of the Moon sweep across us on Earth, on the Moon this was just another day. The lunar nearside was one week into its two-week night, while the Sun shone on the far side in the middle of its two-week day. Because solar eclipses do not affect the health or power supply of the spacecraft, LRO operated normally during the total solar eclipse.<\/p>\n\n\n\n<p>Launched on June 18, 2009, LRO has collected a treasure trove of data with its seven powerful instruments, making an invaluable contribution to our knowledge about the Moon and reminding us, through these eclipse images, of the beauty of our Earth.  <\/p>\n\n\n\n<p>LRO is managed by NASA\u2019s Goddard Space Flight Center in Greenbelt, Maryland, as a project under NASA\u2019s Discovery Program. The Discovery Program is managed by NASA\u2019s Marshall Spaceflight Center in Huntsville, Alabama, for the Science Mission Directorate at NASA Headquarters in Washington.<\/p>\n\n\n\n<p>The Lunar Reconnaissance Orbiter Camera was developed at Malin Space Science Systems in San Diego, California and Arizona State University.<\/p>\n\n\n\n<p>For more information about the LRO eclipse image, visit:<br>\n<a href=\"http:\/\/lroc.sese.asu.edu\/posts\/980\" rel=\"noopener\">http:\/\/lroc.sese.asu.edu\/posts\/980<\/a><\/p>\n\n\n\n<p><strong>By Elizabeth Zubritsky<br><a href=\"https:\/\/www.nasa.gov\/goddard\">NASA’s Goddard Space Flight Center<\/a><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>During the total solar eclipse on Aug. 21, NASA\u2019s Lunar Reconnaissance Orbiter, or LRO, captured an image of the Moon\u2019s shadow over a large region of the United States, centered just north of Nashville, Tennessee.
