Scientists have compiled the first global map of fault ridges on the Moon's basalt plains, discovering that lunar tectonic activity is more extensive than previously thought. This mapping effort has unearthed evidence that some of these ridges are only tens of millions of years old, a relatively recent development in geological terms. Such findings challenge the perception of the Moon's geological stability, particularly in areas designated for future exploration and potential long-term bases.

The research indicates that the dark basalt plains, traditionally seen as smooth and stable, are actually dynamic and subject to geological changes. Interestingly, this is the clearest depiction to date of how the Moon continues to shrink over time, as it wrinkles its surface similar to an aging apple. Such information is critical for planning future lunar missions as they identify regions that may experience geological activity.

Since the Apollo era, the presence of lobate scarps in the highlands has been known, but this study marks the first documentation of widespread similar features across the Moon's surface. This new understanding prompts a reevaluation of lunar geology and emphasizes the need for ongoing research and exploration to reinforce safety and efficacy in future lunar endeavors.
