WEST LAFAYETTE, Ind., May 28 (UPI) -- Unusual minerals in impact craters on the moon may not have originated on the moon, but may be from asteroids that created the craters a U.S. researcher says.
The minerals were once thought to be representative of the lunar interior. Scientists trying to determine what the moon is made of will have to take into account they may not be indigenous to the moon, Jay Melosh of Purdue University said.
