NASA's been worried about how to hand along the skills that led us to the Moon for several years now. If you look at the numbers, a lot of the civil servants at the agency are due to retire in under a decade. NASA was asked to reduce its size through the '70s, & it hasn't really had the chance to hire anyone since. A new generation is starting to move in, but NASA's going to have to get the mentoring process that it once had rolling along smoothly in the '60s back on track before the experiences of the last set of spaceship builders is gone. There's things that just don't come out in blueprints & specs.
