  1. This would make sense. When Thea collided with Earth, part of the original ejecta would have been rocks from pre-collision Earth, while the planet itself melted, destroying all evidence of how it was originally. Those rocks would have floated around until after the moon formed and cooled, and this you have Earth 1.0 rocks on an insert satellite

  2. There was a miniseries in the late 90s about the Apollo missions. It was the first series produced for HBO by Playtone (Tom Hanks’ production company) and had a freaking fantastic cast. It’s called From The Earth To The Moon, if you care to watch I recommend it.

    Anyway, there was an entire episode dedicated to when they found this rock and it was excellent.
