Main Engine Cut Off

Not surprising news, as until now we had expected Atlas V, but still notable.

It’s better news for ULA than it is for Sierra Nevada, but it’s not quite the type of commercial contract that we’d need to see for Vulcan to be a standalone success.

I’m still slightly weary that Vulcan will only exist if ULA wins part of the Air Force’s National Security Space Launch contracts. I expect the winners to be SpaceX and ULA, but at this point the program is so far down the political rabbit hole, that I really have no clue what will happen.
