The following message was originally "bounced" from our meteorobs
mailing list back on 27 Feb 1999... Due to increasing problems with
our mailhost (latrade) at that time, I unfortunately "lost" this
message. I must apologize to Bertil (who has since left our list!)
for misplacing this valuable contribution...

Clear skies!

Some useful info and ideas are described in:
"Comets and the Origin and Evolution of Life",
eds. Paul Thomas, Cristopher Chyba & Cristopher McKay
Springer Verlag, 1997

It contains some discussions about the Chyba/Sagan calculations of
organic material deposition on the prebiotic Earth, and also gives
a lot of good references.

If you do a search on the net you should also find some material
treating the zodiacal dust problem for future planetary searches
in infrared, especially with the planned "Terrestrial Planetary
Finder (TPF)".

cheers,
