Well, you 'know' incorrectly.

True. SSME's used to be pulled after each flight and torn down for
inspection. That's not the case today. Many improvements have been
made to the SSME's over the years, including new LOX and LH2 turbopumps.
The safety and longevity of the turbopumps was a concern with early
SSME's.

I may have "known" incorrectly, but I got my information from a video
aired on the processing of Discovery on NASA TV. They stated each SSME
is removed and refurbished after each mission.
I may be wrong, but if I am it is because the horse was talking out of
the wrong side of it's mouth.
But thanks for the information.

Don't worry about Derek's crap. He obviously relishes in attacking others.
Unfortunately for him the attacks are all too often misplaced. Too bad he
refuses to see the positive and resorts to attacking that which he imagines.

Thanks Clark, I usually don't let it get to me, but I sure don't
understand the behavior of some of the "adults" on these newsgroups. I
thought Usenet was originally envisioned as a vehicle for education
and exchange of information. Some turn it into a "look how much I
know" pulpit.
I know sometimes my questions are elementary, but I subscribe to the
no stupid questions philosophy - usually anyway. I have learned a
wealth of knowledge from this NG - and others too. To those who have
helped me, I give my heartfelt thanks, to the others - thpffffft! :-p,
so there!!!
Regards.
