Scientists baffled by mysterious daily quakes on the surface of the moon have traced back their origin to an unexpected source.

They discovered that some of the tremors were being produced by the descent stage of the Apollo 17 lunar module, left behind on the lunar surface 51 years ago. "Every lunar morning when the sun hits the lander, it starts popping off," says Allen Husker, research professor of geophysics and...…Scientists baffled by mysterious daily quakes on the surface of the moon have traced back their origin to an unexpected source.
