Re: Is suborbital a real market?

On Wed, 21 Nov 2007 18:07:56 -0800 (PST), in a place far, far away,
ohara5.0@xxxxxxxxxxxxxx made the phosphor on my monitor glow in such a
way as to indicate that:

You might say that this is a step towards an orbital market but all
you have to do is to compare E=mgh to E=1/2 mv^2 where v is orbital
velocity to see that suborbital isnt a real step toward orbital.

No, I can't see that, sorry. Even though I'm an astronautical
engineer with three decades of experience, and understand the math.
Can you explain it further?

For orbital, you gotta carry a whole lotta fuel and I dont see Virgin or
Blue Origin or the others trying to do so.

Of course they're not. They have to do things one step at a time.

Can the Virgin ship be modified to carry a big enough engine to get to
200 Km and then can it carry a big enough engine to go orbital?

Of course not. Again, what is the purpose of this seemingly stupid
and irrelevant question?

Otherwise they gotta build a whole new system.

So?
