For anyone not aware of the situation, this is not an official NASA report. It's something that an
intern at NASA did on his free time with a couple buddies. Unfortunately, he put down his NASA affiliation on it and now everyone thinks NASA is wasting their taxpayer dollars on this. You can read the guy's own words about this paper
here.
According to the link, he is a postdoc (he has a doctorate degree, probably in some sort of science or engineering, and most post-doctoral positions are paid positions that last a year to three years, with little or to no chance of renewal). But it sounds like he did this on his spare time, as a fun project with his buddies. We should definitely encourage such hobbies. They're more productive than spectator sports for sure.
