Next, we will invest more than $3 billion to conduct research on an advanced "heavy lift rocket" -- a vehicle to efficiently send into orbit the crew capsules, propulsion systems, and large quantities of supplies needed to reach deep space. In developing this new vehicle, we will not only look at revising or modifying older models; we want to look at new designs, new materials, new technologies that will transform not just where we can go but what we can do when we get there. And we will finalize a rocket design no later than 2015 and then begin to build it. And I want everybody to understand: That's at least two years earlier than previously planned -- and that's conservative, given that the previous program was behind schedule and over budget.
