Researchers have been able to collect data on the moon's change using NASA's satellite-based Gravity Recovery and Interior Laboratory (GRAIL) mission and the Lunar Reconnaissance Orbiter.

DLR researchers are also studying how the conditions and effects of motion that occur in lower gravity can best be simulated on Earth. Video: Successful ‘Moon landing’ using the DLR robotic motion ...

The moon's gravity pulls the ocean toward itself to create the near-side bulge, but this doesn't account for the bulge on the far side. Here, follow a step-through animation that explains why ...
