A lunar probe launched by the Chinese space agency recently brought back the first fresh samples of rock and debris from the moon since the Apollo days.

An analysis of the new moon rocks was published Oct. 7 in the journal Science.

“It is the perfect sample to close a 2-billion-year gap,” said Brad Jolliff, the Scott Rudolph Professor of Earth and Planetary Sciences at Washington University in St. Louis and director of the university’s McDonnell Center for the Space Sciences.

Jolliff is a U.S.-based co-author of the new study.

His teaching and research activities focus on the study of minerals and rocks of the Earth, Moon, Mars and meteorites, and what they reveal about conditions of formation and planetary processes over the past 4.5 billion years.
