#3740 — Space Station Leak May Have Been Caused by Human Error, Russian Reports Say

A small leak detected last week in a Soyuz transport capsule 
temporarily docked to the International Space Station may have been 
caused by a human before the spacecraft launched, according to Russian 
reports. The Soyuz is the only spacecraft currently able to bring 
crewmembers to the space station, and it remains connected to the 
orbiting laboratory until they head home again. [...]

I'd have thought though that if it was in the capsule, then it would have 
shown up while in the flight to the station.
 Unless of course the problem was some kind of seal at the docking point.

Speculation is that a worker accidentally drilled the hole then filled 
it with glue, or something similar.  Thermal cycling, exposure to vacuum 
on one side, and the one atmosphere pressure load on the other 
eventually caused it to fail.

The other theory that Russia has floated is that an astronaut drilled 
the hole while the Soyuz was docked to ISS.  They have also floated the 
suggestion that an unplanned EVA be performed to cut back the insulation 
on the outside of the module to allow for inspection.  I'm not sure how 
that would provide any useful data though.

The idea is that if they find residue of a sealant near the hole, it had
to be made on the ground.

That sounds reasonable.  But the actual EVA would be difficult 
considering that doing delicate work in a pressure suit is extremely 
difficult.  They might accidentally dislodge the residue they're looking 
for.  Also, stuff literally floats away on EVAs, so absence of any 
sealant wouldn't necessarily be conclusive.  So it might not prove 
useful to do such an EVA.

If such an EVA were to be performed, it would be nice if it were done by 
one Russian and one American.  Kind of like counting ballots requires 
representatives of major parties to be present. 

IMHO, of course.
