NASA Extends Lots Of Missions

New Horizons Receives Mission Extension to Kuiper Belt, Dawn to Remain at Ceres

"In addition to the extension of the New Horizons mission, NASA determined that the Dawn spacecraft should remain at the dwarf planet Ceres, rather than changing course to the main belt asteroid Adeona. Green noted that NASA relies on the scientific assessment by the Senior Review Panel in making its decision on which extended mission option to approve. "The long-term monitoring of Ceres, particularly as it gets closer to perihelion - the part of its orbit with the shortest distance to the sun -- has the potential to provide more significant science discoveries than a flyby of Adeona," he said. Also receiving NASA approval for mission extensions, contingent on available resources, are: the Mars Reconnaissance Orbiter (MRO), Mars Atmosphere and Volatile EvolutioN (MAVEN), the Opportunity and Curiosity Mars rovers, the Mars Odyssey orbiter, the Lunar Reconnaissance Orbiter (LRO), and NASA's support for the European Space Agency's Mars Express mission."
