"At this years AIAA Space 2014 conference a panel of experts from NASA and industry discussed the building blocks of to Mars.
The panel discussion: The first step on a path of exploration that will lead to human landings on Mars will be taken in the coming months with the Exploration Flight Test 1 of Orion on a Delta IV Heavy rocket. After that, Orion and Space Launch System will begin a series of exploration missions that will lead to human journeys to Mars. As a capabilities-driven framework, these systems will enable a variety of potential paths to the Red Planet."
Marc's note: The panel discussed the "current" NASA approach. Politics, the private sector, other efforts outside the U.S. were not part of the discussion.
