The International Committee Against Mars Sample Return, or ICAMSR, is an advocacy group of scientists who campaign against Mars sample return. The Committee was founded in the year 2000.〔(ICAMSR - RAISING PUBLIC AWARENESS ABOUT PLANETARY PROTECTION SINCE 2000 ), retrieved 2013-7-16〕 They have been quoted in news stories〔Richard Stenger (Mars sample return plan carries microbial risk, group warns ), CNN, November 7, 2000〕 and books discussing this type of mission. The Committee's name reflects only partially on their actual viewpoint;〔 the ICAMSR charter states their main goal is that samples should be certified safe ''in situ'' or in space first, before they are returned to Earth:〔 The director of ICAMSR is Barry DiGregorio; he has written on the topic of return samples safety on various websites〔Barry E. DiGregorio (Can Martian Microbes Endanger The Earth? ), spacedaily.com〕〔Barry E. DiGregorio (Another Threat to Earth: "Mars Sample Return" ), culturechange.org〕 and magazines.〔Barry E. DiGregorio, (The dilemma of Mars sample return ), ''Chemical Innovation'', August 2001, Vol. 31, No. 8, pp 18–27.〕 Notable ICAMSR advisors include Gilbert Levin who was responsible for one of the Viking spacecraft biological experiments, and Chandra Wickramasinghe.〔(ICAMSR Advisors ), retrieved 2013-7-16〕〔 DiGregorio, Levin, and Patricia Ann Straat have previously co-authored the book ''Mars: The Living Planet'', a 1997 re-examination of the Viking spacecraft biological experiments. The ICAMSR website devotes several pages to promoting Levin's controversial interpretation that the Viking Labeled Release experiments demonstrated signs of life on Mars.〔 This is currently a minority view amongst scientists.〔 In 2000, a CNN article said that: "In fact, DiGregorio, the author of ''Mars: The Living Planet,'' suggests epidemics that originate in space might have already taken place. Mass extinctions over the ages have been tied to giant meteorite or comet strikes. But such cataclysms could perhaps be more fully explained, he said, if science considers the possibility that extra-terrestrial viruses played a role, for example when the age of the dinosaurs ended 65 million years ago."〔 The same CNN article also said that "Many planetary scientists dismiss the risks as unwarranted or highly exaggerated, saying the surface of Mars is most likely lifeless, anyway."〔 Carl Sagan was among the voices raising concerns about a Mars Sample Return in the 1970s; quotes from him feature prominently on the ICAMSR website. The main page of the ICAMSR website cites a passage from Sagan's ''The Cosmic Connection'' (1973, p. 114), in which he wrote:〔 ==See also== *''Diseases from Space'' (book) 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「International Committee Against Mars Sample Return」の詳細全文を読む スポンサード リンク
