In an unprecedented slap at NASA’s endorsement of global warming science, nearly 50 former astronauts and scientists--including the ex-boss of the Johnson Space Center--claim the agency is on the wrong side of science and must change course or ruin the reputation of the world’s top space agency. Challenging statements from NASA that man is causing climate change, the former NASA executives demanded in a letter to Administrator Charles Bolden that he and the agency “refrain from including unproven remarks” supporting global warming in the media. The letter was signed by seven Apollo astronauts, a deputy associate administrator, several scientists, and even the deputy director of the space shuttle program. --The Washington Examiner, 10 April 2012
