Re: tektites

Ruby:
It takes ALOT of energy to release material from the surface of a body, in
particular planets.  That is why we only have a handful of meteorites from
the Moon and Mars.  Also, I don't know that much about tektites but it
would seem to me, that they could be made of a different composition if the
crustal material of a planet was of a different composition than  say of
earth's crust.  Furthermore, I think a tektite from another body would melt
VERY easily as it passed through the atmosphere....good question though!
