The $1 trillion estimate comes from updating for inflation the cost of the Mars mission proposed in 1989. This plan included doubling the size of the yet to be built Freedom Space Station, use it as an orbital dry dock for building a massive spaceship fully equipped with all fuel and provisions, additional orbital support stations for fuel storage and work crew living space, and a permanent lunar base to support the project, and was costed at $450 billion at the time!<br /><br />Nowadays derided as a 'Battlestar Galactica' approach, the plan was obsolete when the Mars Direct and similar missions were proposed, where the cost is vastly reduced by 'in-situ resource utilisation' - that is, using the Martian atmosphere to manufacture propellant.<br /><br />Unfortunately, when the VSE was proposed some journalist googled 'Mars mission' and found the obsolete plan and reported it as the current cost after adjusting for inflation (being, as most journalists are, ignorant of these matters). Succeeding journalists now find the $1 trillion figure when <i>they</i> google.
