Procedures are being developed for TPS inspection from ISS on approach.
If repair were needed, Atlantis would first dock, then grapple ISS with
the RMS, then undock while still attached by the RMS, rotating to place
the appropriate part of the Orbiter in easy access to spacewalkers using
the Station robot arm.

Is the shuttle arm strong enough for this? I gather the station arm
was designed to be (at a time when HTV-style capture was being
considered rather than conventional docking).

Given that this is the plan, I suppose the answer must be "yes" or
"yes, but only in an emergency such as this" or something. But I
wasn't aware that the shuttle arm could do it.

Modifications to the cameras in the Orbiter umbilical well will not be
ready for STS-114, and the astronauts will use handheld cameras to
image the ET, downlinking the images to Earth.

They would roll after ET separation? Or is there naturally a sight
line which gives them a good enough view of the ET?

I'm sure some of this is still being working out, but curious minds
want to know the current thinking.
