Bush to announce Beginnings of Man to Mars mission
This is not going to come cheap - key quote
No one, least of all members of Congress, knows how NASA would pay for lunar camps or Mars expeditions. When the first President Bush proposed such a project, the estimated price tag was $400 billion to $500 billion.

Excuse me for being a grouch, but doesn't it seem fitting that an administration that has allowed spending to rise faster than any other administration in recent memory is on the verge of proposing another new program?
