Moon Mystery: GRAIL Data Show How Gravitational Anomalies Developed
2013-05-31 06:19:45

redOrbit Staff & Wire Reports - Your Universe Online Researchers from Purdue University and MIT have solved the long-standing mystery of why the moon´s gravitational force is stronger in some areas than in others. This irregular gravitational force has been observed ever since the first satellites were sent to the moon, when orbiting probes would pass over certain craters and impact basins, and periodically swerve off course before plunging toward the lunar surface and then...

A huge amount of scientific data have been accumulated by the CE-1 lunar orbiter. Using laser altimeter data, Jinsong Ping and Qian Huang et al obtained improved 3D lunar topography, and based on this, they had made new discoveries (such as impact basins and volcanic deposit highlands) of some ancient topographic characteristics on the lunar surface. Chao Chen and Qing Liang et al found the South Pole-Aitken (SPA) basin as the biggest mascon on the moon and put forward a fault structure...

Meet MIT professor of physics Maria Zuber. She's dynamic, intelligent, intense, and she's on a quest for the Grail. No, not that Grail. Zuber is the principal investigator of the Gravity Recovery and Interior Laboratory "” "GRAIL" for short. It's a new NASA mission slated for launch in 2011 that will probe the moon's quirky gravity field. Data from GRAIL will help scientists understand forces at play beneath the lunar surface and learn how the moon, Earth and other terrestrial planets...

Owing to SMART-1's high resolution and favourable illumination conditions during the satellite's scientific operations, data from Europe's lunar orbiter is helping put together a story linking geological and volcanic activity on the Moon. The combination of high-resolution data from SMART-1's AMIE micro-camera and data from the US Clementine mission is helping scientists determine the tectonics of the Moon's giant basins and the history of volcanic flooding of mid-sized craters, inside and...

Near the end of the mission of Apollo 16, on April 24, 1972, just before returning back home to Earth, the three astronauts released one last scientific experiment: a small "subsatellite" called PFS-2 to orbit the Moon about every 2 hours. The intention? Joining an earlier subsatellite PFS-1, released by Apollo 15 astronauts eight months earlier, PFS-2 was to measure charged particles and magnetic fields all around the Moon as the Moon orbited Earth. The low orbits of both subsatellites were...

Ancient mega-catastrophe paved way for the dinosaurs, spawned Australian continent COLUMBUS, Ohio -- Planetary scientists have found evidence of a meteor impact much larger and earlier than the one that killed the dinosaurs -- an impact that they believe caused the biggest mass extinction in Earth's history. The 300-mile-wide crater lies hidden more than a mile beneath the East Antarctic Ice Sheet. And the gravity measurements that reveal its existence suggest that it could date back about...
