If it's a silly question, why did you fail to ANSWER it?
Again, phrased differently, does the lack of a polar orbit mean a mission's not sufficiently remarkable? Is a trip to London from the USA not remarkable simply because one didn't also go to the rest of Europe? Your response was that you like Mars Express but find the questions I've asked to be mere rabble rousing. And of course you conveniently ignored how NASA refuses to take advantage of the permission Congress has given it to shake up its procurement practices by finally offering competitive prizes:

I won't ask if you profit from the status quo, as I wouldn't expect you to publicly admit it if you do.
