Sol Alan Stern (born November 22, 1957) is an American engineer and planetary scientist. He is the principal investigator of the New Horizons mission to Pluto and the Chief Scientist at Moon Express.〔(Dr. Alan Stern named Chief Scientist for Moon Express | Solar System Exploration Research Virtual Institute )〕〔(Moon Express Blog | Google Lunar XPRIZE )〕 Stern has been involved in 24 suborbital, orbital, and planetary space missions, including eight for which he was the mission principal investigator. One of his projects was the Southwest Ultraviolet Imaging System, an instrument which flew on two space shuttle missions, STS-85 in 1997 and STS-93 in 1999.〔〔http://www.plutoportal.net/alanstern.htm〕 Stern has also developed eight scientific instruments for planetary and near-space research missions and has been a guest observer on numerous NASA satellite observatories, including the International Ultraviolet Explorer, the Hubble Space Telescope, the International Infrared Observer and the Extreme Ultraviolet Observer. Stern was Executive Director of the Southwest Research Institute's Space Science and Engineering Division until becoming Associate Administrator of NASA's Science Mission Directorate in 2007. He resigned from that position after nearly a year. In early 2009 Stern's name was mentioned as a potential contender for the position of NASA administrator under President Obama's administration.〔(Who Will Be the Next NASA Administrator? )〕〔(Earth Scientist Emerges as Possible Replacement for NASA Chief )〕 Stern has stated however that he is not interested in the position at this time given his desire to spend time with his family. ==Life and career== Stern was born in New Orleans, Louisiana, the son of Joel and Leonard Stern.〔 He graduated from St. Mark's School of Texas in 1975. He then attended the University of Texas, Austin, where he received his bachelor's degrees in physics & astronomy and his master's degrees in aerospace engineering and planetary atmospheres. He earned a doctorate in astrophysics and planetary science from the University of Colorado, Boulder.〔(NASA - Associate Administrator for the Science Mission Directorate S. Alan Stern )〕 From 1983 to 1991, Stern held positions at the University of Colorado in the Center for Space and Geoscience Policy, the office of the Vice President for Research, and the Center for Astrophysics and Space Astronomy. He received his doctorate in 1989. From 1991 to 1994 he was the leader of Southwest Research Institute's Astrophysical and Planetary Sciences group and was Chair of NASA's Outer Planets Science Working Group. From 1994 to 1998 he was the leader of the Geophysical, Astrophysical, and Planetary Science section in Southwest Research Institute's Space Sciences Department, and from 1998 to 2005 he was the Director of the Department of Space Studies at Southwest Research Institute. In 1995 he was selected to be a Space Shuttle mission specialist finalist and in 1996 he was a candidate Space Shuttle payload specialist but did not have the opportunity to fly on the Space Shuttle. His research has focused on studies of our solar system's Kuiper belt and Oort cloud, comets, the satellites of the outer planets, Pluto, and the search for evidence of solar systems around other stars. He has also worked on spacecraft rendezvous theory, terrestrial polar mesospheric clouds, galactic astrophysics, and studies of tenuous satellite atmospheres, including the atmosphere of the Moon. In 2007, Stern was listed among Time Magazine's 100 Most Influential People in The World. On August 27, 2008 Stern was elected to the Board of Directors of the Challenger Center for Space Science Education.〔(Challenger Center )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alan Stern」の詳細全文を読む スポンサード リンク
