Let's just hope the people involved will get well. How long a delay are we looking at here for STS-120 and 122? Long enough to just get 3 launches this year?

NASA saying they believe they have enough spare capacity not to cause schedule issues, but this is before they know the full state of the six remaining RSRM 98 center and forward segments (STS-120) and RSRM 99 aft segments (STS-122).

I'm sure they'll work it out, but it's too early to say.

By the way, the injuries to the people on the train is a more serious situation, but I'm sure you can all understand, we cover the vehicle hardware here, so I'm concentrating on that.

Not known yet. It all depends if the segments are undamaged or ot.

I'm informed that if a single segment is trashed, then the same segment from the other motor will be scrapped. But two new matching segments can be cast and inserted. This would fix the thrust imbalance issue.

Another memo (and back on to the people for a moment), notes all minor injuries, with one serious (but not life-threatening), and he's been air lifted from the scene.

Do they have another train "set" to transport segments besides this one?

Non life-threatening is certainly good news, now let's hope for non life-altering as well - some stitches and a couple of days off, or some such thing.

We'll take some damaged segments over anyone being killed, that's for sure.

The lead locomotive looks like it has sunk so far in the mud that it is flush with the top of the mud.  Being such a swampy remote area, how in the heck do you clean this mess up.

Weird how 2 loco's and passenger wagon have come the off rails and tipped over, then a couple of the the trucks carrying the segments are upright, then one of the trucks has tipped over then the rest behind seem upright. I wonder why the one in the middle has tipped and the ones either side of it have remained upright.

Big cranes, after the bridge is rebuilt.  Railroads routinely deal with this and worse.

It looks like one of the four is on it's side and the other three are fine.  Knowing NASA, I bet those segments are packed pretty effectively.  I'm guessing that segment isn't too bad off.

Segment damage is going to be key here for the 120 and 122 stacks.
Ex-Apollo, waiting for NASA to finish what we started.

The bridge collapsed????  It would almost be comical if it wasnt so serious.

Offline Chris Bergin

NASA are happy it won't hurt the schedule (snippet from a long e-mail):

"ATK has two additional flight sets completed and in storage in Utah ready for shipment and one flight set in Final Assembly. With the amount of RSRM hardware in process, it appears there would not be an impact to the Space Shuttle Schedule."

These segments weigh on the order of 100 tons each, correct?

It's not going be easy to recover the toppled segment given the surrounding soil conditions.  They'll probably have to do it with a crane on the rails.

Would a Sky Crane Helicopter be able to lift it? Or would mods to the container need to be made?

Sky cranes are super wimpy as cranes go.  Roughly 10 tons capacity.
