NASA seems to be dead set on a course to ensure the Shuttle's life
cannot be extended. Internally, it might be leaving some drap doors
opened to enable a restart of the programme, but that doesn't appear to
be visible to the public.


Since no change in course can happen until January 19th 2009, and since
NASA is rarely a priority when a new government takes office, I think it
unlikely that NASA would be retasked to drop that CEV thing and continue
with Shuttle before it is really too late to restart the Shuttle. And
politically, it would be fairly hard to do because of the image (whether
correct or not) that the Shuttle costs more than that mythical CEV project.

What it would really take is for some very respected scientist to
convince the next president that the shuttle would be far more useful in
developing a mission to mars than some glorified Apollo capsule. (aka:
use Shuttle to assemble the mars expedition ship).


What is likely/possible is that should there be more launch delays due
to glitches etc, they would agree to lift the date-based deadline and
allow the already planned missions/flights to launch. (aka: deadline
based on number of flights).

....Correct. Sci.space is still around, and actually gets a post or two
on rare occasions. I honestly can't recall the last time I looked
there, tho. Might have been '03 or thereabouts. But again, because of
the way usenet is designed, decommissioning a group is practically
impossible. There have been rare occasions, but those haven't occured
since the days of Spaf, and IIRC Tale was the last one who had a
couple of racist-based groups purged.

Oh really? So Bush's decision to end the shuttle program and begin VSE were
simply a coincidence after Columbia was destroyed?

Two years after it was destroyed! There's only three problems with the
shuttle: 1: there's only three Orbiters left; 2: the location of the Orbiter
itself - on top of the stack would have been fine for Columbia at least; 3:
using solid boosters - the original liquid design would mean that Challenger
and her crew would still be with us.

Problem (2) is due to a bad design choice (hindsight being what it is).

Problems (1) and (3) are political. Typical. The total development saving,
at the time the decision to use solids instead of liquids was said to be
$600 million - 6% of total (claimed) development costs. It's also cost more
because the cleaning of the solids is highly dangerous and very difficult
work.

Liquids would have been less expensive on launch and would have made the
entire stack lighter at launch - less propellant for a smaller ET. Simply
using liquid boosters, with the Orbiter in its current position would
probably have saved Challenger too.

the original design had launch boost escape too, all that remained of
that was the strong crew area, thats why it survived breakup. it was
originally supposed to be a pod, with parachute.

probably both crews would still be with us today

if the shuttle were liquid with launch boost escape it could of been
modernized elminating the hydrazine, and cut operating costs, to
continue flying........

One spare ET will be build (to my information) and could enable an ultimate
STS-134. There would be a lot of equipment to bring up yet.

Define schedule. There are no more ET's being built so it will be
retired in 3 years

You won't find anybody of import that would agree with that. Any
respected person knows the shuttle needs to be retired.

Wouldn't the spare be reserved in case there was the need to fly a rescue
mission on the last shuttle flight? If you flew the last ET, there wouldn't
be one left to fly a rescue mission.

The real reason why Energia won't be making a come back is also simple -

no longer exists. The stages for Energia 3 were damaged when the building
roof collapsed. I think all the equipment was destroyed afterwards.

That's just one copy of the hardware. The real reason Energia won't be
coming back is because it would be far too expensive to re-open the
production lines and far too expensive to launch the thing. It's far too
big for anything that Russia would reasonably want to launch.

Yes. In fact the Titantic held more boats than required by law and I
believe actually exceeded most standards at the time.

Lifeboats were not intended to necessarily hold the entire manifest, but
just enough to transport them to other craft in a timely fashion.

The MOST flammable?

Given the German's safety record, it wasn't necessarily a bad decision. And
in fact the Germans were trying to buy helium from the US in order to
increase safety. So even they, with their good safety record recognized
they could improve things.

I'm not even sure what your point is with those 5 examples since you're
mixing design flaws (Hyatt Regency walkway) with aging flaws (I-35W bridge).

Yes and no. The only flight you absolutely positively need a stand-by
shuttle is the Hubble mission.

For station missions, if you plan in advance, you probably could reasonably
fly a last one and rely on other measures to help ensure crew safety.

For station missions, if you plan in advance, you probably could

safety.

Possibly, if you flew the shuttle with as few crew as possible. If you
launched with four crewmembers on the shuttle, you still need two extra
Soyuz flights to bring them all down, assuming that you launch the Soyuz
with one pilot on board. Care to guess what it would cost to have Russia
build, and have ready to fly, two Soyuz spacecraft? It's not like they have
a lot of spares sitting around. They tend to build them as they need to fly
them.

I think the reality is that the spare ET will never be flown.
