I just read that XCOR laid off its’ remaining employees with a few core people kept on contract. This is another shot against the vision that I have blogged and commented about many times. The concept being that sub-orbital RLVs would create companies and teams with experience creating RLVs. This is where orbital RLVs would come from. It appears that I was off so badly as to defy excuses.
XCOR seems to have joined a number of other sub-orbital efforts that have folded, or gone into stealth mode at least. Armadillo and TGV being a couple of the best known along with a dozen or so of varying credibility around X-Prize time. I don’t think Virgin Galactic should be considered a validation for my vision even if they are eventually successful.
SpaceX is coming at RLV from the other direction, backing into it from an expendable. I’m sure I’ve posted or at least commented on several occasions that this was a bad idea with little chance of working. Blue Origin Â seems to be using its’ sub-orbital RLV as an X-vehicle for its’ orbital class RLV. It would be a stretch to suggest this is similar to my vision as it seems to be a parallel effort rather than serial as I suggested might be necessary. The other orbital companies talking RLV seem to be dragging their heels on any changes so I discount them for this post at least.
It does seem to validate one argument I’ve made from time to time about the difficulty of sub-orbital vs orbital flight. The argument by some others was that orbital flight was 8 times the velocity of sub-orbital flight and difficulty rises as the square of velocity so that made it 64 times as hard. The ones making that argument didn’t believe my calculation that it was more like 4-5 times the difficulty. Maybe they can note that several attemptees have had far more than 1/64 of the funding of SpaceX or Blue Origin with no flying hardware.
There is a bright spot or two though. Masten is still going, and a few others are still in the game. Come on guys, you are the last hope to make me right on this one.
