New study of craters shows that moon’s surface gets churned every 81,000 years, not every million years.To read the rest, rock on over to "Moon Just Got 100-fold Younger".
“I like it when theories are proven wrong, or exciting new things come up,” remarked Kathleen Mandt of Southwest Research Institute, quoted by New Scientist. That’s how to put a cheerful spin on an orders-of-magnitude correction. “The Lunar Reconnaissance Orbiter is starting to show there’s a lot we don’t know about the moon.” Data from LRO are showing a much higher influx of meteorites to the moon’s surface, implying that future astronauts stand a bigger-than-trivial chance of being in danger from flying rocks and dust. The data raise questions about the age of the lunar surface.
