Took the wind right out of your sails? Huh! There seems to about 30 to 35 papers not 20 to 25 as I stated before. Actually if you count all papers produced in relationship to Mars Analogs on Earth there is probably 100 or More...

I see you fail to address the fact that these folks who wrote these papers have often Ph.D. after their names are scientist as you are not and write for publication in engineering and science publications.

Unfortunately some of the best papers are abstracts or titles only as I don't have the money to subscribe to all the science rags around... But, still the easy to find and easy to post ones come out of such strange off color rags like IEEE and SAE publications...

I also see you haven't given us the simple engineering analyze showing the NASA Mars Reference Mission is less engineered than earlier mission designs. Should I be surprise?
