A few questions about the tile-scanning procedu

Are the astronauts going to have to hand-fly the scan of the orbiter's
belly, or has this been automated? I assume that they'll want to dock
the OBSS and move it into initial position by hand...

Last I heard, the scan was hand-flown and was planned to be so for at least
the early flights. That could have changed, though.

How long is the scan expected to take?

7.5 hours total, of which 6 is the actual scan.

Will the divot scan be done at JSC, or by the orbiter crew?

Not sure what you mean here. The crew will be flying the arm and recording
the data, but the subsequent image analysis will be done at JSC.

Just curious how much crew time is going to be devoted to this on the
first (and subsequent) flights...

It will be a lot more time-consuming on the first two flights (at least)
than on the subsequent ones. Last I heard, full leading-edge scans will
only be done until the wing leading edge sensor network is validated. After
that, the scans will only cover areas of known or suspected impacts.
