Which just says "potential impacts" not more shuttle delays.

They won't delay the launch for that. Five weeks might be enough time
to get a recent spacewalker (or other planned spacewalker in training
for 134 or ISS?) up to speed on the bare minimum to get the job done,
and leave the detail work up to a Stage EVA (by ISS crew.)

Yes, they seem to have come on very well with evas in recent years, even
allowing people to basically walk by the seat of their pants. a good deal
of it is due to the very good tiny cameras on the helmets now in use and a
lot of experienced people advising on the ground. I just hop that when the
Shuttle stops they retain the expertise.

well if they play fast and loose with training and something goes
wrong???

better to delay launch some more than risk a disaster in space, or
damaging a module that cant be replaced because the shuttle is ending

Then something goes wrong. We're not talking about grabbing an oil
worker and sticking him on the Shuttle to go blow up a comet and save
the world here. I think we'll see an STS-131 spacewalker step in here,
since they worked with an MPLM also. The main tasks aren't that
different and those that are can wait for another EVA by ISS crew.

Unlikely. RMS ops is where things could go wrong and you'd get damage
to ISS, Kopra is an EVA'er and Flight Engineer, but there are others
trained for the Flight Engineer work who can step in.

"may" is the operative word here.

If the accident had caused an injury which would absolutely never heal
in time, NASA would be quickler to announce a crew change.

Bicycle accidents are more likely to affect clavicle than hip though. So
I am a big suspicious of the "broken hip" scenario. But it is still
possible.

If there is a change that the injury will heal in time, NASA will likely
wait until much close to flight time to make decision (monitoring
progress of healing).

If the injury turns out to be minor, NASA could ignore it from a media
point of view and simply comfirm he is in full health at the time it
does the same for other crew members. (this avoids having to provice any
specifics about his injury).

Question: forgetting this accident, wouldn't an astronaut's backup
continue to train right until the last minute and be able to be swapped
very quicklty ?

And if an astronaut already has EVA experience, I suspect training one
for a new mission would be much faster since he wouldn't have to learn
how to move around (tethering etc) and how to operate the fancy space
tools like the screwdriver. He just needs to be told which screws to
remove and what torque setting to put onto the screwdriver.

And remember that all of the steps needed during an EVA are already
documented "on paper" so it isn't as if the sick crewmember is the only
one with the knowledge on how to accomplish a task.

nasa hasnt trained backup crews for years.
