With Atlantis now a sick puppy, are there any possibility that Endeavour
would be given STS117 and Atlantis retasked to 118 ?
This would give them more time to fix Atlantis and its tank, without
delaying ISS assembly so much.
Does Endeavour have similar uplift capabilities as Atlantis ?
Or is Endeavour just not anywhere near being ready to be mated to SRBs and
its own ET ? |

The repairs to Atlantis are minor. The ET repairs will take most of the
time. Swapping orbiters will slow things down more.

More.

Not even close to ready.

But do they have a spare srb/tank stack?

Spare SRBs? There should be no need - the SRBs sustained even less damage
than Atlantis. If an ET swap is necessary STS-117 will use the tank
originally planned for STS-118.

I was not sure, I thought if they had a set stacked it might be easier just
to move the orbiter over.

With the flight rate so low, I'm sure it's not worth it to keep an "extra"
set of stacked SRB's and ET on an MLP.

If they decide that the tank needs to be replaced, how would this be done ?
Wouldn't this require full destacking since orbiter and SRB's are attached
to the tank ?
Would it be technically possible to lift the orbiter up out of the way, and
then pull the MLP out, and then bring the second MLP in where a new SRB/ET
can be assembled and shuttle then lowered back and attached to the new stack ?
(this way, once Atlantis is sent back to the pad, they can bring the other
MLM with damaged ET back in for repairs and then mate Endeavour later on.) |

Yes. Atlantis would be dismounted from the Tank and lowered to the VAB
transfer aisle, probably going back to the OPF. Then the External Tank
would be disconnected from the SRBs and moved to the transfer aisle,
out to the barge, and back to Michoud. Then the STS-118 External Tank
would be brought in, stacked to the SRBs, Atlantis brought back in and
mounted on the Tank, and back out to Pad A.

Technically yes, but you wouldn't want to leave the Orbiter "hanging
around" like that for so long. Lower it to the Transfer Aisle and then
just swap out the damaged Tank. Besides, there isn't another stack of
SRBs and ET waiting, and if there were, it would be in the other High
Bay, so just move the Orbiter from one High Bay to the other.

Yeah, or just swap missions and launch STS-118. I would hope that Endeavor
is ready. Or, was NASA depending on Russia to Bail Them Out Again if
something went wrong with Atlantis?
Maybe SpaceX will have Dragon available soon?

I hope SpaceX is careful touching the Tar Baby called NASA. |

When did Michoud re-open? I seem to have missed that happening,
because the last thing I remember seeing was that the Michoud workers,
and their families, were going to KSC to do their work. That has to
have been fairly soon after Katrina.

About six weeks after Katrina. Some heroic effort there. The real heroes
were the team that rode out the storm, keeping the pumps running. It's a
miracle the facility didn't take a lot more damage than it did.
