[meteorite-list] Extra-solar material?

[Mark Crawford]

There's a PDF of the full paper linked from the abstract. If the results 
are correct (it's 12 years old, I don't know if the findings have been 
challenged since) then we would seem to have a steady stream of 
interstellar particles from at least 2 discrete extra-solar sources. 

I wonder if there would be value in a Stardust-like probe - perhaps in 
Earth orbit - aimed at trapping micrometeor particles before the impact 
the atmosphere. Or even the high-altitude 'fly paper' flights, intended 
to sample interplanetary dust particles (McSween refers to this in Ch 1 
of MATPP). Either approach would seem to offer the opportunity to 
realise a proportion of specimens which originate from outside our 
system.  I've no idea how they would be positively identified as such, 
however.
