FIGURE E.10 Distribution of principal-investigator (PI)-led mission costs (blue) and non-PI-led mission costs (red) as a fraction of the median cost of all missions with 40 to 80 percent complexity (green trendline in Figure E.9). The median cost of PI-led missions is 0.7 times that of the other missions, with only 16 percent of the PI-led mission costs exceeding the median of the costs of other missions. The PI-led missions also have a smaller fractional cost variance. SOURCE: Provided by the Aerospace Corporation under contract with the National Research Council.
