This was supposed to be a secret until this coming Wednesday, and it was secret, right up until someone spilled the beans almost a week early:

Buzz is building about a planned 2018 private mission to Mars, which may launch the first humans toward the Red Planet.

Its future is further imperiled by the decline of the Creation Museum, whose visitors were expected to be a huge source of funding for the ark park.
