Frank Sietzen has an interview with the NASA Administrator in this month’s Aerospace America [note: it’s apparently not a permalink–they’re playing some games with frames. You’ll probably have to dig it out of the table of contents].
It’s worth a read if you’re interested in space policy. This was the question (and answer) that I found most intriguing.
Q: Do you think the Space Launch Initiative (SLI) is on the right track, or do you want to restructure it?
A: We?ll see.
