Cripes. These guys are ridiculous. Not getting enough money to solve
technical problems that were already solved a half-century ago?

"The officials say the funds currently available to develop Orion and
its Ares launch rocket mean the faster timeline is no longer tenable.

Engineers also need time to grapple with a range of technical issues as
they develop the new systems. These include trying to reduce the levels
of vibration astronauts are likely to experience when they lift off atop
the new Ares vehicle. "

GMAFB.

I'm a big NASA supporter, but this shit is too much.

Cheers.

"Reduce the levels of vibration"?

This generation of NASA is teh suck. Ask John Glenn what his "levels of
vibration" were on top of that Atlas firework.

Let there be no doubt tonight -- no doubt!
That they shouldn't have played the Old Gold and Blue.
Not tonight!

The problem of vibration comes from the modified sold rocket booster
(an extended version of the SRB used on the Shuttle) as the first
stage of the Ares I booster. Solid rockets vibrate like hell and that
vibration is carried into the crew capsule at the top of the stack
which can cause injury. Because it has two SRB's strapped to the
stack, the Shuttle shakes much more than the old liquid-fueld Atlas
that launched John Glenn. Ares I and its solid first stage is not the
way I would have gone. I would have modified a Delta IV or Atlas V,
commercial launchers readily available. NASA Director Mike Griffin
decided Ares I should have a bit of the Shuttle involved and so the
SRB as the first stage. It'll work but something has to dampen all
that shaking and that's going to take quite a bit of testing. The
sense at NASA is that if Obama gets in, all bets are off, anyway.
Most likely, American astronauts are no longer going to have any kind
of a ride after he guts the program. If McCain gets in and Griffin
goes away, it wouldn't surprise me to see a move toward the Delta or
Atlas. None of this is the fault of NASA engineers. They are capable
but they are also not pushed to avoid the minimum of a five-year gap
that now exists after the last shuttle flies in 2010. Ultimately, the
President and Congress have to really, really care about the manned
space program, properly fund it and nurture it. This hasn't been true
since, oh, about 1969. We get the space program we deserve. In fact,
since we the people are in charge of this country, everything that
happens to us is exactly what we deserve.
