New study reveals moon is still shrinking as scientists detect over 1,000 surface cracks

Scientists at the Center for Earth and Planetary Studies, part of the National Air and Space Museum in the United States, have confirmed that the Moon continues to shrink, causing ongoing reshaping of its surface, according to a new scientific study that identified more than 1,000 relatively recent cracks across lunar terrain.

The research indicates that these newly detected fractures could pose potential risks for future lunar exploration missions, as they may be linked to powerful lunar tremors. Scientists stressed the importance of incorporating seismic risk assessments into mission planning, including landing site selection and surface operations.

Lead researcher Cole Naipafer explained that upcoming missions to the Moon will play a crucial role in gathering more precise data on lunar tectonics and seismic activity. Such information, he noted, will directly influence the safety and scientific success of both current and future exploration programs.

“We are living in a very exciting time for lunar science and exploration,” Naipafer said, highlighting the growing momentum in space research.

Although scientists have known since 2010 that the Moon has been gradually contracting as its interior cools, the discovery of additional surface fractures marks an important step forward in understanding lunar geology.

Researchers believe the findings will help build a clearer picture of the Moon’s internal structure as well as its thermal and seismic history.

The study suggests that improved knowledge of lunar seismic behavior could enhance hazard prediction models and help space agencies better prepare for surface operations.

In light of these findings, NASA — which is planning to return astronauts to the Moon by 2028 — may adopt additional safety measures to protect astronauts and exploration equipment during future missions.
