I'd much rather see them fix the stick than use a Delta heavy.
But cancel the heavy and lander. Robots are for exploring, humans
are for /exploiting/, where the expense can be recouped, or even
a profit made.

That's the only way we're going to have large numbers of people
in space. This whole moon and mars thing kinda limits the number
of people in space to a handful at best for the next couple of
generations. And completely eliminates any market potential.

Spending say ....400 billion and ...40 years to put men on mars
when ....4 billion and ....4 years....with robots can do 95% as good
is just plain ...Lunacy...defined.

Men need to be building something profitable and useful in low
earth orbit. Until we can do that, we certainly can't make any
profits farther out.


Let the robots drift into the deep freeze.

Hardly surprising. And with my idea for a Delta V (55 tonnes to LEO;
smaller payloads, but launched more often - seven times a year), there's no
need for an Ares V at all.

The Delta team already has several ideas about how to grow Delta IV. What
is lacking is demand for larger payloads. DOD may say they're interested,
but they're always reluctant to actually spend the money to increase payload
capacity.

Those six-PLF designs are interesting.

If you mean those Delta IV Heavy derivatives, note the notation at the bottom
which says 'new pad/infrastructure'. I read that as $$$, worse than
'batteries not included'. Comments?

I agree, that it all another game at getting their hands into our
pockets. Would you care to suggest otherwise?

Perhaps our NASA should be shut down.

My peanut gallery intuition (such as it is) tends to agree and figures
it would become, effectively, Delta V.
