I was being more definitive that 'space' by using 'orbit' because I finally figured out that orion was doing the old 'bait 'n switch'.

I cannot believe how disingenuous you are being. I showed the actual post where the other poster actually said 'surface-to-space', not 'surface-to-orbit'. How can it be bait-and-switch when he first said "space"?

Because it is still the relative rotation that drives the energy requirements and launching east is like 'taking off into the wind'.

Rotation of what? It has to be the earth rotating.

OOPS!.

That last post was from me, I didn't realize my husband was logged on to MY laptop. There will be repercussions...
