…which is to say, the problem with HEFT.

There is a civil war going on within the space agency, and even at headquarters itself. On one side is the old guard, who still cannot envision a NASA that doesn’t develop, own and operate its own launch systems. On the other are those who see that it must abandon this old failed paradigm in order to both afford to, and have the robust ETO infrastructure necessary to, move aggressively and sustainably beyond low earth orbit. The people running space policy on the Hill are (so far), sustaining the old guard, but they’re going to have a collision with reality in the next year, and they’re going to have more trouble than in the past getting their colleagues to go along with them, as hard choices have to be made about the budget, and progress in the new mode of contracting becomes increasingly undeniable. It cannot continue.

I should note that Clark’s well-justified rant is based on this post by Jon Goff, in which he vents his frustration at the wilful blindness of the HEFT team to both technical and fiscal reality.
