Analysis of a piece of lunar rock brought back to Earth by the Apollo 16 mission in 1972 has shown that the Moon may be much younger than previously believed.
This is concluded in new research conducted by an international team of scientists that includes James Connelly from the Centre for Star and Planet Formation, Natural History Museum of Denmark, University of Copenhagen. Analysis of a piece of lunar rock brought back to Earth by the Apollo 16 mission in 1972 has shown that the Moon may be much younger than previously believed.
Over the last couple of days I have fallen down a research rabbit hole -- I began with a question about clay minerals on Mars and find myself, today, writing about the history of major impact basins on the Moon.
The trail that led me here has to do with geologic time scales -- the stories that geologists tell about the major events that happened in the history of a planet.
Most of the mare lava flows are from 3 to slightly less than 4 billion years old.
indicating that substantial melting and flow occurred on the Moon long after its formation.
Luna rock from Apollo 16 "We have analysed a piece of lunar rock that was brought back to Earth by the Apollo 16 mission in 1972.
And the new research suggests that it happened earlier in the timeline of the Solar System than we thought - just 60 million years after our star system's birth, compared to previous estimates of 150 to 200 million years afterwards.
To come up with the new lunar age estimate, the team analysed Moon rocks taken from the lunar surface during the Apollo 14 mission.
The reason we've never been able to accurately date the age of the Moon in the past is that there's very few well-preserved Moon rocks left on its surface.
Most of the rocks brought back by Apollo astronauts are breccias - mixes of different rocks that have been mashed together by the meteorite strikes that plague the Moon, thanks to its lack of atmosphere.
