NASA is simultaneously incredible at three things: Arguably the best in human history at researching, developing, and deploying novel, past-the-bleeding edge technology; by orders of magnitude, the greatest explorers ever; and sales. The only reason General Motors doesn't tell you your car will last 90 days and give you a 90 day warranty - and then brag about how it's lasted 10 years - is that nobody would buy it. NASA can say whatever they like and we buy it.
