<p>Not sure that this situation indicates anything wrong with their selection process. After all, there have been astronauts for over 40 years and this is the first incident of this type (believe a male astronaut committed suicide a few years back). Also, LN was an astronaut for over 10 yrs before this event; as best as anyone knows, nothing like this occurred in her entire life up to this point. Thus, not sure the selection process is at issue. </p>
<p>There may, however, be a need to examine life as an astronaut. Lots of incredibly talented, highly educated, type A personalities who join NASA (presumably) to go into space but may not get that opportunity for at least a decade, may get only one trip into space, and may not have enough to do during their many years of “down time” other than training and PR events.</p>
