Story summary

NASA's Lunar Reconnaissance Orbiter Camera (LROC) captured grabens around Mare Humorum, showing the Moon's crust has been pulled apart over time.
Research led by Thomas Watters finds the Moon generally contracts from cooling, while some regions still extend.
The Rimae Hippalus system, a network of valleys, illustrates the complex interaction.
Analyzing these features helps scientists understand the Moon's history and identify safe sites for future missions.
