In a paper published in the journal Earth and Planetary Sciences, researchers described the substance as a “dark greenish and glistening impact melt breccia.”
Impact melt breccia is a type of lunar rock formed from asteroids striking the surface of the moon.
In their paper, the scientists explain that the substance discovered by the Chang’e 4 mission’s Yutu-2 rover is similar to two melt breccia samples returned from the moon by NASA’s Apollo 15 and Apollo 17 missions.
