It looks like CEV may be taking this approach.


Let's hope so, especially for the crew launch/entry module.

Since the CEV appears to be a more modular vehicle, there isn't really
any reason to give all of the pieces to one contractor. You may want
a prime contractor to oversee everything, but that doesn't mean that
entire modules couldn't be subcontracted out.

Jeff


That approach was tried for SSF. Work Package 1 was all the pressurized
elements and internal systems, contracted to Boeing. Work Package 2 was
the integrated truss and external systems like the TCS radiators,
integration of the PV arrays with the truss and power
storage/distribution systems, external GNC stuff, etc, contracted to
McDonnell Douglas; Work Package 3 disappeared early on and I can't
remember all of what they were to do - earth observation science stuff,
I think; WP 4 was solely the external electrical stuff like batteries,
power regulators, etc., IIRC. WP1 wasn't really in charge although it
was sort of seen as "first among equals." There was (theoretically) a
central SSF Program Office at NASA HQ that was in charge but they were
far-removed from things happening in the detailed design process and not
very effective at all at controlling the various Center contracting
offices for the various work packages (which were at MSFC, JSC and
Goddard), let alone influencing the contractors directly.

Anyway, the hassles of having so many organizations involved with so
many facets of the design process really slowed things down and
complicated matters greatly. Just flowing interface requirements
properly across so many organizations and people was a tremendous chore.
A single, central management entity is really going to be necessary to
ensure that everyone is using the same requirements, that all changes
get flowed through, costed out properly, and implemented uniformly, etc.
The best example I can think of a system like this is how Boeing managed
and integrated the Saturn booster program, despite not actually building
much if any of it, or how operations at many/all of the various National
Laboratories are subcontracted out.

Schaltegger made the phosphor on my
monitor glow in such a way as to indicate that:

The mistake with ISS was not having work packages per se, but in
splitting up the NASA management for them (for obvious political
reasons, since the primary purpose of the program was to give NASA
something to do after the end of the Shuttle development). Multiple
contractors could have been managed if they'd had a single government
manager.

That's what I meant by having a prime contractor. The prime
contractor would be in charge of the entire CEV program, but could
subcontract out various modules. For example, the TLI stage and its
tankage could be subcontracted out, but the prime contractor gets to
worry about how it integrates with the other parts.

If two modules don't fit or can't talk to each other, it's the prime
contractor's fault.

In re the ISS, Rand Simberg is cited as stating that the mistake of ISS is
splitting up the management thereof for political reasons. The writer is of
the opinion that ISS is the classic mistake of running Space out of the
Foreign Ministry's office, instead of the appropriate commission or
ministry. In the UN, that duty is the UN Commission on Space; in the USA,
NASA. And so forth.

The writer goes one further step: the sooner that the Government Agencies
can spin off Space into two divisions -- Science & Exploration, and Commerce
& Industry (including Colonization & Settlement -- the latter to be handled
under the private sector) the better.

Or for an example outside of the space program, you have the FBM/SWS
program which not only has multiple 'prime' contractors, but (had)
multiple locations where the prime contractors hardware came together
for final assembly. Also their were multiple locations where the
hardware was operated, not only the boats themselves, but the training
and testing/support centers.

SSPO (under varying acronyms) served as a goverment single point of
contact, but there was also a contractor (VITRO) who oversaw various
interfaces.

The particular flight profile was not relevant; the overall goal (an SSTO
RLV with low per-flight cost) was. So the RFP was written generally enough
for competing approaches to be tried - otherwise, the RFP would have been a
disguised sole-source solicitation to MDAC, since they were the only ones
proposing an SSTO with that particular flight profile.


Not necessarily; if the RFP were written differently, I think that
Lockheed and Rockwell would have proposed vehicles that matched the
DC-X flight profile.

I was a bit surprised to see NASA write the RFP generally; usually, they
are guilty of overspecifying it to the point that you can tell they had a
particular company/product in mind and wrote the RFP to practically assure
that only that product could win. At least in this area, NASA got X-33
right, in my opinion.


Let me put it this way... suppose X-33 had actually worked, instead
of failing : would there have been a "next stage" that would _not_ have
been tied to the Lockheed design's configuration?

I'm beginning to think X-33 should have been less ambitious to begin with,
so that they could have done experimental flight structures and materials,
or advanced heat shielding, without any sort of experimental engines
necessary.

The local election boards in Florida in 2000 were dominated by Democrat

And they still couldn't get enough to win.

Because the Governor and Secretary of State were Republicans.


Even the NYT, Times and Newsweek gave up on that line of argument
shortly after the election.


Yes, but Dick won't. He still fantasizes that Al Gore is president.


People who fantasize that George Bush won the election fair and square,
and that it was *Al Gore* who tried to steal it, should not throw
stones.

On or about Sat, 24 Apr 2004 04:58:56 GMT, Dick Morris
made the sensational claim that:

Um, he did.

and that it was *Al Gore* who tried to steal it, should not throw


It was.

Having said that, what really should have happened would have put Gore in
the White House.

Having won his home state (my home state, as a matter of fact) would
have obviated the circus in Florida. That he didn't underscores a
couple of things, not the least of which is how much his campaign just
didn't grasp the demographic changes back at home while he was off being
a Friend of Bill and loyal shield carrier for 8 years.

A couple years earlier. It's not clear whether he would have stayed
there in 2000, though as an incumbent, he probably would have been
tougher to beat.
