But as crew members Frank Borman, James Lovell, and William Anders all later recalled, the most important thing they discovered was Earth.Using photo mosaics and elevation data from Lunar Reconnaissance Orbiter (LRO), this video commemorates the 45th anniversary of Apollo 8's historic flight by recreating the moment when the crew first saw and photographed the Earth rising from behind the Moon. Narrator Andrew Chaikin, author of A Man on the Moon, sets the scene for a three-minute visualization of the view from both inside and outside the spacecraft accompanied by the onboard audio of the astronauts.The visualization draws on numerous historical sources, including the actual cloud pattern on Earth from the ESSA-7 satellite and dozens of photographs taken by Apollo 8, and it reveals new, historically significant information about the Earthrise photographs. It has not been widely known, for example, that the spacecraft was rolling when the photos were taken, and that it was this roll that brought the Earth into view. The visualization establishes the precise timing of the roll and, for the first time ever, identifies which window each photograph was taken from.The key to the new work is a set of vertical stereo photographs taken by a camera mounted in the Command Module's rendezvous window and pointing straight down onto the lunar surface. It automatically photographed the surface every 20 seconds. By registering each photograph to a model of the terrain based on LRO data, the orientation of the spacecraft can be precisely determined.Andrew Chaikin's article Who Took the Legendary Earthrise Photo From Apollo 8? appeared in the January, 2018 issue of Smithsonian magazine. It includes the story of the making of this visualization.A Google Hangout discussion of this visualization between Ernie Wright (creator of the visualization), Andrew Chaikin, John Keller (LRO project scientist), and Aries Keck (NASA media specialist) was held on December 20, 2013. A replay of that hangout is available here.Ernie Wright presented a talk about the making of this animation at the 2014 SIGGRAPH Conference in Vancouver. He also wrote a NASA Wavelength blog entry about Earthrise that includes links to educator resources related to LRO. || ", "hits": 498 }, { "id": 4109, "url": "https://svs.gsfc.nasa.gov/4109/", "result_type": "Visualization", "release_date": "2013-10-02T00:00:00-04:00", "title": "Lunar Far Side: From Luna 3 to LRO", "description": "In October of 1959, the Luna 3 spacecraft launched from the Baikonur Cosmodrome in Kazakhstan. Luna 3 was the third spacecraft to reach the Moon and the first to send back pictures of the Moon's far side. The pictures were noisy and indistinct, but because the Moon always presents the same face to the Earth, they offered views of a part of the Moon that had never been seen before.The far side of the Moon is surprisingly different. The most striking difference evident in the Luna 3 pictures is the absence of the large, dark seas of cooled lava, called maria, that cover a substantial fraction of the Earth-facing near side. The far side is instead densely peppered with impact craters of every size and age.Fifty years later, in June of 2009, Lunar Reconnaissance Orbiter (LRO) launched from Kennedy Space Center in Florida. Using LRO's global elevation maps and photographic mosaics, both of which are of unprecedented quality and detail, it's possible to accurately recreate the view captured in the pictures from Luna 3. As seen here, Luna 3 was directly over 12°N 120°E at a distance of 61,700 kilometers above the surface, and its camera was banked 17.5° clockwise from vertical relative to the Moon's north pole.The thicker blue longitude line at 90°E, along the left side of the LRO image, marks the boundary between the near and far sides of the Moon. To the left of that line are the familiar maria Crisium (the circular spot near the 9 o'clock position), Marginis, Smythii (both east of Crisium), Humboldtianum (in the north), Australe (near the south pole), and the eastern edge of Fecunditatis. The bright spot near the center of the disk is a complex of unnamed craters bordered by King, Langemak, Gregory, and Abul Wafa craters. The brightness is enhanced because it's near the subsolar point. The dark, sharp-edged shield shape in the southern hemisphere, with the white dot in the middle, is Tsiolkovskiy crater and its central peak. The dark spot to the southeast of Tsiolkovskiy is the crater Jules Verne. The mare in the northeast is Moscoviense. || ", "hits": 335 }, { "id": 11283, "url": "https://svs.gsfc.nasa.gov/11283/", "result_type": "Produced Video", "release_date": "2013-07-25T00:00:00-04:00", "title": "Smiling In Space", "description": "The Mona Lisa is already one of the most famous paintings in the world, but it’s now being recognized for another reason: a digital version of it traveled 240,000 miles to the Lunar Reconnaissance Orbiter (LRO), a NASA satellite orbiting the moon.

They were taken on December 24, 1968 by the crew of Apollo 8, the first humans to leave low Earth orbit.The sight of a small, intensely blue Earth rising above the barren, gray horizon of the Moon was one of the few things that NASA and the crew of Apollo 8 had not thoroughly planned and rehearsed beforehand. As historian Robert Poole noted, this lack of preparation meant that the sight of Earth came with the force of a revelation, not just for the astronauts but for everyone on the ground. We came all this way to explore the Moon, Apollo 8 astronaut Bill Anders said, and the most important thing is that we discovered the Earth.Using the latest elevation data from Lunar Reconnaissance Orbiter, this visualization attempts to recreate what the astronauts saw. The virtual camera of the rendering software is put in the position of the Apollo 8 spacecraft at the time of the photographs, as the spacecraft emerged from its fourth pass behind the Moon. It shows a two-minute interval centered on 16:39:06 UT (10:39 a.m. Houston time) on December 24, 1968. This is around the time of AOS (acquisition of signal), the moment when radio contact is re-established after being lost on the far side of the Moon.The position and motion of the spacecraft are based on a state vector, a set of (x, y, z) position and (vx, vy, vz) velocity values, published in NASA's Apollo 8 Mission Report about a year after the flight. The animator translated these values, given in Moon-centered inertial coordinates for Besselian year 1969.0, into a modern coordinate system, then calculated an orbit. The spacecraft was 110 km (68 miles, 60 nautical miles) above the surface of the Moon at 11.2°S 113.8°E when the Earthrise photograph was taken. || ", "hits": 411 }, { "id": 10951, "url": "https://svs.gsfc.nasa.gov/10951/", "result_type": "Produced Video", "release_date": "2012-04-19T00:00:00-04:00", "title": "Earthrise 2.0", "description": "On December 24, 1968, three Apollo astronauts circled the moon, becoming the first humans ever to do so.

All of a sudden, a bright sliver of light appeared from behind the lunar horizon. Within seconds, a sphere with dazzling white swirls and vivid shades of blue came into view. The astronauts quickly positioned the onboard cameras, first capturing a black-and-white image of Earth rising, and then snapping a color photo of the Blue Planet floating above the horizon.

In short, the moon wobbles. At least, it does to our eyes. A casual glance skyward won't reveal this, but when a full month of lunar views gets compressed into 12 seconds, as in the visualization below, it's impossible to miss. This rocking like a ship at sea is called libration, from the Latin for balance scale. Instead of just one side, we actually see about 59 percent of the lunar surface over the course of an orbit. The sped up view also reveals how the apparent size of the moon changes in the sky depending on where it is in its elliptical orbit. Its farthest point, the apogee, and nearest point, perigee, differ by more than 10 percent.

This matters because LRO relies on sunlight to power its systems and instruments. Although it spends half of every orbit on the night side of the Moon, each night side pass lasts only an hour. For the June 15 eclipse, LRO will be in the dark for more than twice as long.During a previous total eclipse, LRO hibernated, turning off all of its instruments to conserve its battery power until the Moon emerged from the Earth's shadow. For the June 15 event, LRO will leave on the Diviner Lunar Radiometry Experiment. Diviner will measure the cooling of the Moon's surface during the eclipse. This unique temperature record is expected to reveal information about the roughness and composition of the swath of lunar surface visible to Diviner's sensors during the eclipse.The visualization archived on this page shows the view of the eclipse from the Moon, looking back toward the Earth and the Sun. On the Moon, this event is a solar eclipse. As the Sun disappears behind the Earth, the umbral shadow sweeps across the lunar landscape, and as our eyes adjust to the darkness, the stars come out, and the lunar surface looks a dull red.

Celestial north is up. As the Moon enters the umbra (the part of the shadow in which the Sun is completely blocked by the Earth), the shadowed side of the Moon appears black while the sunlit side remains bright. Only when the Moon is almost completely within the umbra is it possible to see the faint red glow of the shadowed side, some 10,000 times fainter than the sunlit Moon. The redness is sunlight filtered and refracted by Earth's atmosphere.
