On the 50th anniversary of the first Apollo landing on the moon, American adults cite the 1969 lunar landing as NASA’s most important achievement in its 60 year history. In a national survey conducted by the University of Michigan, 35% of American adults (age 18 or older) mention the first lunar landings as one of the two most important achievements of NASA when asked in an open-ended format. “This level of public recall and recognition reflects the deep-seated impact of the first moon landing in American culture,” said Jon Miller, director of the International Center for the Advancement of Scientific Literacy at University of Michigan’s Institute for Social Research. It is important to recognize that only 45% of today’s adults were alive at the time of the first lunar landing on July 20, 1969.
