"The in-depth assessment confirmed the basic vehicle concepts of the SLS, allowing the team to move forward and start more detailed engineering design, " Gerstenmaier said.
Several models have been put forward as to how such a feat of "geo-engineering" might actually be achieved, most involving the positioning of a reflective shield of some sort out in space.
And what we're hoping to do is at least some of the decision-making based a little bit more on what are the engineering plans that determine this is the best project to go forward.
