\"download\"<\/a>Beyond Earth, Jupiter\u2019s moon Europa is considered one of the most promising places in the solar system to search for signs of present-day life, and a new NASA mission to explore this potential is moving forward from concept review to development.<\/span><\/p>\n

NASA\u2019s mission concept — to conduct a detailed survey of Europa and investigate its habitability — has successfully completed its first major review by the agency and now is entering the development phase known as formulation.<\/span><\/p>\n

\u201cToday we\u2019re taking an exciting step from concept to mission, in our quest to find signs of life beyond Earth,\u201d said John Grunsfeld, associate administrator for NASA\u2019s Science Mission Directorate in Washington. \u201cObservations of Europa have provided us with tantalizing clues over the last two decades, and the time has come to seek answers to one of humanity\u2019s most profound questions.\u201d<\/span><\/p>\n

NASA\u2019s Galileo mission<\/span><\/a>\u00a0to Jupiter in the late 1990s produced strong evidence that Europa, about the size of Earth\u2019s moon, has an ocean beneath its frozen crust. If proven to exist, this global ocean could hold more than twice as much water as Earth. With abundant salt water, a rocky sea floor, and the energy and chemistry provided by tidal heating, Europa may have the ingredients needed to support simple organisms.<\/span><\/p>\n

The mission plan calls for a spacecraft to be launched to Jupiter in the 2020s, arriving in the distant planet\u2019s orbit after a journey of several years. The spacecraft would orbit the giant planet about every two weeks, providing many opportunities for close flybys of Europa.\u00a0The mission plan includes 45 flybys, during which the spacecraft would image the moon’s icy surface at high resolution and investigate its composition and the structure of its interior and icy shell.<\/span><\/p>\n

NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, has been assigned the responsibility of managing the project. JPL has been studying the multiple-flyby mission concept, in collaboration with the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland, since 2011.<\/span><\/p>\n

Instruments selected for the Europa mission’s scientific payload were\u00a0announced<\/span><\/a>\u00a0by NASA on May 26. Institutions supplying instruments include APL; JPL; Arizona State University, Tempe; the University of Texas at Austin; Southwest Research Institute, San Antonio and the University of Colorado, Boulder.<\/span><\/p>\n

\u201cIt\u2019s a great day for science,\u201d said Joan Salute, Europa program executive at NASA Headquarters in Washington. \u201cWe are thrilled to pass the first major milestone in the lifecycle of a mission that will ultimately inform us on the habitability of Europa.\u201d<\/span><\/p>\n

NASA’s Science Mission Directorate in Washington conducts a wide variety of research and scientific exploration programs for Earth studies, space weather, the solar system and the universe.<\/span><\/p>\n
