Any more information about this apparent 'dent'? When was it first
'discovered'? What was the last previous time that area was surveyed when
the dent WASN'T there? Has anything like it been seen anywhere else on the
exterior? Seems like the shielding is doing its job -- what might have
happened if the event had occurred in a region WITHOUT shielding?

Nov 4 ISS Status Report:
Next week the SSRMS (Space Station Remote Manipulator System) will be used
for an outside inspection of what appears to be a "dent" in the Lab module's
exterior surface, specifically in the MM/OD (micrometeoroid/orbital debris)
shielding surrounding the pressure shell. [The shielding, made of an
aluminum alloy, is designed to absorb the initial impact of MM/OD, slowing
it down while breaking it into small fragments before it hits the pressure
shell. The shielding is 0.13 cm (0.05 in.) thick and is separated from the
pressure shell by a 10.2-cm (4-in.) gap.]
