Noah E. Petro and John W. Keller, NASA Goddard Space Flight ,Center, Solar System Exploration Division, Greenbelt, MD. Mission details » How did the Moon form? Today, there are several main theories on the origin of the Moon. Main purpose for extended mission THE SECOND EXTENDED SCIENCE MISSION FOR THE LUNAR RECONNAISSANCE ORBITER: STATUS, SCIENCE GOALS, AND DATA DELIVERIES. When the extended mission began, LRO returned to a more elliptical frozen orbit where gravity and other modeling errors caused numerous violations of mission accuracy requirements. The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric polar mapping orbit. Data collected by LRO have been described as essential for planning NASA's future human and robotic missions to the Moon. In addition, LRO's objectives included the search for surface resources and the measurement of the lunar radiation environment. End-of-Mission Disposal 6.0 After 1-year of science observations, orbiter will be boasted into a higher orbit to reduce maintenance requirements. (Noah.E.Petro@nasa.gov John.W.Keller@nasa.gov ) The Lunar Reconnaissance Orbiter (LRO) has … Prediction accuracy is particularly challenged during periods when LRO is in full-Sun. LRO Mission Phase Definition Table Includes planning and execution of end-of-life operations. For example, the Cassini mission has been extended repeatedly not only for the excellent science it is producing, but also because no future missions to Saturn are currently planned by any space faring nation. new discoveries and objectives of the lunar reconnaissance orbiter’s EXTENDED MISSION: VOLCANISM AND INTERIOR J.

LRO is currently in the Extended Mission phase, focused on collecting the data needed to address key lunar science questions, including chronology/bombardment, crustal evolution, regolith evolution, and polar volatiles. July 26, 2016 In the 7 years that the Lunar Reconnaissance Orbiter (LRO) has been orbiting the Moon, the data returned from its instruments has revolutionized what we know about the Moon – it is a dynamic world, rich in resources like water ice. The Lunar Reconnaissance Orbiter spacecraft (LRO), launched on June 18, 2009, began with the goal of seeking safe landing sites for future robotic missions or the return of humans to the Moon as part of NASA's Exploration Systems Mission Directorate (ESMD). In the case of LRO, it is the last remnant of what was to be a series (now cancelled) of robotic missions to the Moon. Could include controlled/uncontrolled impact on the Lunar surface.
