I
thought about the chances for meteorites from Venus or even Mercury a couple of
days ago, too. My conclusion (which isn’t a scientific one, just an
educated guess): Venusian atmosphere is so dense that it will slow down an
impacting body considerably (reducing his energy) and slow down ejecta as well
(making it impossible to reach escape velocity). With Mercury, I guess the sun
will be the “big catcher” that will collect all ejected material. But
once again, I am not a scientist J Bernhard -----Original
Message----- A little off the subject
but was up early thinking about this. The Russians did eventually land on Venus
and got atmospheric isotope %. Been reading about NWA011 age ~2GY? O
isotopes seem wrong but the age would be about right. Why probably ot that
one, Venus still has activce volcanos thus basaltic material.
Theorectically how much more difficult would it be for a Venusian to find it's
way to earth? What would we expect in a Venunsian basalt meteorite or why
haven't any been identified? Howard Wu
