NASA's Lunar Reconnaissance Orbiter (LRO) discovers cliffs that indicate that the moon has been shrinking in the past.
NASA issued a report yesterday that they found evidence that the moon has been shrinking in the past. NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft discovered cliffs in the lunar crust indicate the moon shrank globally in the geologically recent past and might still be shrinking today.
"We estimate these cliffs, called lobate scarps, formed less than a billion years ago, and they could be as young as a hundred million years," said Dr. Thomas Watters of the Center for Earth and Planetary Studies at the Smithsonian's National Air and Space Museum, Washington. While ancient in human terms, it is less than 25 percent of the moon's current age of more than four billion years. "Based on the size of the scarps, we estimate the distance between the moon's center and its surface shrank by about 300 feet," said Watters, lead author of a paper on this research appearing in Science August 20.
There you have it, enjoy the moon as long as it still up there. More details in this NASA report.
