I can't think of a better way to spend a trillion dollars, and yes, that's the estimate. The AP reports: President Bush will announce plans next week to send Americans to Mars and establish a permanent human presence on the moon, senior administration officials said Thursday night. Bush won't propose sending Americans to Mars anytime soon; rather, he envisions preparing for the mission more than a decade from now, one official said. In addition to proposing the first trip to the moon since December 1972, the president wants to build a permanent space station there.
