MATTHEW WEINZIERL: I think it’s a really fundamental distinction, partly because there’s a misunderstanding that’s easy to have out there in the world, which is, we hear so much as you said about SpaceX and Blue Origin and various other space companies, and it seems like the days of NASA and the Department of Defense and other international space agencies playing a big role in space might be over, and there’s a sense in which that role has changed a lot, but the role is definitely not over. We kind of put all of our eggs into the space shuttle and ISS basket, and it was only the space shuttle was retired following the 2003 Columbia accident, that the private sector was given a real opportunity to try to be an agent in directing the U.S. space enterprise.
