These maps of the near and far side of the moon show the gravity gradients as measured by NASA's GRAIL mission, highlighting a population of linear gravity anomalies. Red and blue correspond to stronger gravity gradients. Tony Greicius, Randal Jackson, Naomi Hartono. The new map, created by the Gravity Recovery and Interior Laboratory (GRAIL) mission, is allowing scientists to learn about the moon's internal structure and composition in unprecedented detail. When launched in September 2011, the probes were named GRAIL A and B. The Moon is in synchronous rotation with Earth, always showing the same face with its near side marked by dark volcanic maria that fill between the bright ancient crustal highlands and the prominent impact craters. A very oblique view of a crater on the far side of the Moon, as imaged by NASA's Lunar Reconnaissance Orbiter. Red corresponds to mass excesses and blue corresponds to mass deficiencies. The Apollo 11 Command and Service Modules are photographed from the Lunar Module. Ranger 8 image of the Mare Tranquillitatis (Sea of Tranquillity) area of the Moon taken from 511 km about 4 minutes before surface impact. To view the lunar gravity map, visit http://bit.ly/grailtour .

This image shows the variations in the lunar gravity field as measured by NASA's Gravity Recovery and Interior Laboratory (GRAIL) during the primary mapping mission from March to May 2012. Lunar Gravity Maps Lunar Prospector gathered data at an altitude of 62 miles above the Moon in 1998-1999. NASA's Jet Propulsion Laboratory in Pasadena, Calif., manages the mission for NASA's Science Mission Directorate in Washington. The probe's gamma ray spectrometer will measure the Moon… The map shows more small-scale detail on the far side of the Moon compared to the nearside because the far side has many more small craters. The twin probes, named Ebb and Flow, fly in formation around the moon, detecting the tiny changes in the distance between them caused by lunar mountains, craters and subsurface mass concentrations. LRO - Eclipse Observations from LRO Lithograph. This moon map shows the gravity gradients calculated by NASA's GRAIL mission. Producer: A pair of twin spacecraft from NASA’s Gravity Recovery and Interior Laboratory (GRAIL) mission have completed a new map showing the Moon’s gravity in unprecedented details. Since the gravitational field of the Moon affects the orbit of a spacecraft, one can use these tracking data to detect gravity anomalies. Local gravity field models for the Moon Sander Goossens. GRAIL's extended mission science phase began Aug. 30 and will conclude Dec. 17. This low-bulk crustal density agrees well with data obtained during the final Apollo lunar missions in the early 1970s, indicating that local samples returned by astronauts are indicative of global processes. Ebb and Flow were placed in a near-polar, near-circular orbit at an altitude of approximately 34 miles (55 kilometers) on Dec. 31, 2011, and Jan. 1, 2012, respectively. Lunar Orbiter 1 new of the Moon and crescent Earth. According to Zuber, the moon's gravity field preserves the record of impact bombardment that characterized all terrestrial planetary bodies and reveals evidence for fracturing of the interior extending to the deep crust and possibly the mantle. "With our new crustal bulk density determination, we find that the average thickness of the moon's crust is between 21 and 27 miles (34 and 43 kilometers), which is about 6 to 12 miles (10 to 20 kilometers) thinner than previously thought," said Mark Wieczorek, GRAIL co-investigator at the Institut de Physique du Globe de Paris. As the end of mission nears, the spacecraft will operate at lower orbital altitudes above the moon. The field shown resolves blocks on the surface of about 12 miles (20 kilometers) and measurements are three to five orders of magnitude improved over previous data. The $496 milion Grail mission launched in September 2011 to map the moon's gravity field with unprecedented precision. "With this crustal thickness, the bulk composition of the moon is similar to that of Earth. NASA's LADEE mission came to an end as the spacecraft executed a planned de-orbit into the surface of the Moon at nearly three thousand, six hundred miles per hour. A view of the severely damaged Apollo 13 Service Module. The gravity field map reveals an abundance of features never before seen in detail, such as tectonic structures, volcanic landforms, basin rings, crater central peaks and numerous simple, bowl-shaped craters. The Apollo 11 Lunar Module Eagle, in a landing configuration was photographed in lunar orbit from the Command and Service Module Columbia. "When we see a notable change in the gravity field, we can sync up this change with surface topography features such as craters, rilles or mountains." The … As they fly over areas of greater and lesser gravity caused by visible features, such as mountains and craters, and masses hidden beneath the lunar surface, the distance between the two spacecraft will change slightly. The Gravity Recovery and Interior Laboratory ( GRAIL ) mission comprises a pair of satellites launched in September, 2011 and placed in orbit around the Moon in January, 2012. GRAIL is part of the Discovery Program managed at NASA's Marshall Space Flight Center in Huntsville, Ala. Lockheed Martin Space Systems of Denver built the spacecraft. The Sun shone from the west (left). New lunar gravity maps point out a stark and unexpected difference between the sizes of ancient asteroids that slammed into the moon billions of years ago and the sizes of … The dikes are among the oldest features on the moon, and understanding them will tell us about its early history." Andrea Jones, Caela Barry, Tracy Vogel The two satellites, named > Ebb and Flow, used radio signals to precisely measure their separation as they flew in formation, one following the other in the same nearly circular polar orbit. Very precise microwave measurements between two spacecraft, named Ebb and Flow, were used to map gravity with high precision and high spatial resolution.

Red areas have stronger gravity, while blue areas have weaker gravity. This impact record is preserved, and now precisely measured, on the moon. "This data revealed a population of long, linear gravity anomalies, with lengths of hundreds of kilometers, crisscrossing the surface. NASA's twin Grail probes have created an ultra-precise gravity map of the moon, revealing that its crust is almost completely pulverized. The first detailed map of the gravity fields on the Moon’s far side shows that craters there are different than those on the near side. Very precise microwave measurements between two spacecraft, named Ebb and Flow, were used to map gravity with high precision and high spatial resolution. These are the first scientific results from the prime phase of the mission, and they are published in three papers in the journal Science.

JPL is a federally funded research and development center managed for They were renamed Ebb and Flow in January by elementary students in Bozeman, Mont., in a nationwide contest. Final pictures taken by the Ranger 8 P-camera about 1/2 second before impact. In addition to global gravity field models of the Moon such as GRGM1200A, our group has also developed local models of the lunar gravity field using GRAIL data.Global gravity models are often described using spherical harmonics.To express features at small scales in spherical harmonics, an expansion up to high degree and order is needed. Other articles where Gravity map is discussed: ocean basin: Exploration of the ocean basins: The resulting gravity map provides comprehensive coverage of the ocean surface on a 5′-by-5′ grid that depicts five nautical miles on each side at the Equator). The principle used depends on the Doppler effect, whereby the line-of-sight spacecraft acceleration can be measured by small shifts in frequency of the radio signal, and the measurement of the distance from the spacecraft to a station on Earth. This supports models where the moon is derived from Earth materials that were ejected during a giant impact event early in solar system history." A 'Pounded Moon' Gravity Map: Big Pic The map, created by the twin GRAIL spacecraft, should shed light on the evolution of the moon and the solar system's rocky planets.
