Moon is Shrinking: NASA Reveals Ongoing Contraction, Impact on Earth & Astronauts

• NASA and Smithsonian Institution scientists confirm the Moon is still shrinking due to its cooling interior.
• The Moon's diameter has decreased by approximately 50 meters over several hundred million years.
• Shrinkage causes cracks and thrust faults, leading to moonquakes, some reaching 5.5 on the Richter scale.
• New studies show widespread tectonic activity, including in the South Pole region, a planned Artemis landing site.
• While shrinkage poses risks to future lunar missions, its slow rate has no significant impact on Earth's tides or gravity.
