NASA’s LRO Reveals Incredible Shrinking Moon
08.20.10
 
Newly discovered cliffs in the lunar crust indicate the moon shrank globally in the geologically recent past and might still be shrinking today, according to a team analyzing new images from NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft. The results provide important clues to the moon's recent geologic and tectonic evolution.

Cut 1 - 00:27 - “The research involves looking at very high-resolution Lunar Reconnaissance Orbiter images of the surface of the moon for landforms called “lobate scarps” that reflects crustal shortening or contraction of the moon.  We have now found that these lobate scarps occur everywhere on the moon, which means that the moon has contracted or been shrinking globally.”

Cut 2 - 00:16 - “What’s exciting about these findings for me is that the moon is not a dead body. It’s not an object where everything that happened on the moon happened billions of years ago.”

Cut 3 –-00:22 - “These scarps could be younger than a billion years, they could be in fact as young as a couple of hundred million years old, or they could be even younger than that. And that means in geologic terms, the moon is active.”
