Re: samples from Apollo 12
Hi Steve,
I remember reading about the area explored by Pete and Alan: it was right on an ejecta site coming from Tycho's formation.
We know now that crater Tycho was formed 109 Million years ago.
And Tycho is problably the most recent large impact crater on the Moon. It feels strange that astronauts walking on a plain, on Oceanus Procellarum, could find evidence of an event occuring so far away.
