Asteroid: Impact August 8, 2006

Scott what I was trying to bring out is the planets made of rock are
just as old as the Sun. The Sun made of hydrogen and helium,and rocks
made of heavier elements. Heavy elements come out of a supernova
explosion. They came into the Sun's gas cloud as dust,and it was
this dust that created rocks (meteors asteroids,and larger rocks) I'm
talking about the accretion process that built the rock planets more
than 4600 million years ago. Its dust sticking together Not all
these space rocks are alike. Comets are dirty snow balls. Some rocks
have lots of iron,and some little or none. Same goes for rock planet
cores. Scott you have to much faith in how good a rover can
analyze rock,and how are labs can analyze the rocks here on Earth.
Reality is its at best a theory that Mars rocks are the ones found on
Antarctica. TreBert
