re: Manned Mars on Time Magazine cover
I wrote a letter to the editors of Time suggesting that Easterbrook's got to look beyond the numbers in the 90 Day Report if he wants a more reasonable apraisal of the costs of such a mission (ie, Zubrin's work, of course). Anyone who wants to can write to the editors via the Time website. I certainly hope they publish some indication that the dollar amounts Easterbrook's thrown around are not considered definitive.
