I think this is an issue of lack of experience with subcooling the LOX. This is only the second flight of the new vehicle. With sufficient flight experience, they’ll get it down, I’m sure.
I didn’t try to wangle an invite, because I’m currently in Missouri, sort of on vacation (which is why the light blogging as well). But if I’d been in CA, I’d have probably driven up, just to see who else was in attendance.
It’s too bad — it’s an interesting concept. This is the sort of thing that DARPA/NASA should be doing, but the latter has to waste money on a giant rocket.
If NASA is smart, they’ll be putting a plan together for a return to the moon, to present to the next administration, preferably with a lot of public/private partnership.
