I've read a number of articles suggesting that the USA has a Mars colony, including (if I recall correctly, but I can't find the link now) one where an official in China stated that they believed the USA had a secret military base on Mars, and another that indicates that the USA attempted to recruit the great-granddaughter of President Eisenhower for a Mars colony project. While the latter seems to likely be malarkey, it seems to be one of the more common references to a USA Mars colony project. I'm curious about whether anyone's put any serious thought whether the USA could secretly create a Mars colony.
Is there any evidence that the USA either has or plans a secret colony on Mars?
Is it logistically possible that the USA could start a Mars colony and keep it secret?
