Understanding Lunar Resources

A new study suggests that perhaps as many as twenty five percent of large lunar impact craters still contain material from the asteroid that created them.  That would make understanding the origin of the Moon more complicated for scientists, but it would also make the Moon an even richer resource for the support of future human space operations.

It's also possible that pieces of the very early Earth, blown away from the planet by the titanic collisions of the young Solar System, could be found on the Moon.   Such pieces could even preserve evidence of the beginning of life on Earth, long since lost to us by the intervening geologic activity of our home world.
