The Gravity Recovery and Interior Laboratory (GRAIL) was an American lunar science mission in NASA's Discovery Program which used high-quality gravitational field mapping of the Moon to determine its interior structure.
Way back in September, NASA's Jet Propulsion Laboratory sent a duo of Lockheed Martin-produced spacecraft toward one of its favorite test subjects, the Moon, as a part of its GRAIL mission ...
The Grail Movement is a millenarian new religious movement [1] which originated in central Europe in the early 1920s, revolving around the teachings of self-proclaimed messiah figure Oskar Ernst Bernhardt (also known by his pen name Abd-ru-shin 1875-1941), principally In the Light of Truth: The Grail Message.
While results from the primary science mission are just beginning to be released, the collection of gravity science by the lunar twins continues. GRAIL's extended mission science phase began 30 August and will conclude on 17 December 2012. As the end of mission nears, the spacecraft will operate at lower orbital altitudes above the moon.
Gravity Recovery and Interior Laboratory was a Moon orbiter that provided higher-quality gravitational field mapping of the Moon to determine its interior structure. [47] The two small spacecraft GRAIL A (Ebb) and GRAIL B (Flow) separated soon after the launch and entered Lunar orbits on December 31, 2011, and January 1, 2012, respectively. The ...
The twin GRAIL (Gravity Recovery and Interior Laboratory) satellites orbited the Moon from December 2011 to December 2012. The data they sent back deepened our understanding of the Moon’s gravity and interior composition. [2] GRAIL was NASA’s first planetary mission with instruments fully dedicated to education and public outreach.
