80% of National Aeronautic Space Administration (NASA) employees were over the age of 40, with the average age for workers being 47, according to 2009 reports. The average age of newly hired NASA workers is 41. In comparison, the average age of NASA employees during the first travel missions to the moon in the 1960s was 28 years old. This change in the average age of NASA employees is thought to be due to an increase in employment options for aeronautical engineers, such as in private space companies, than there was in the 1960s. The reduced emphasis on new space missions is also considered a reason for a decline in recent college graduates from applying with NASA; however, on average at least 500 students train or work there during college.
