Related: About this forumGrail satellites show Moon's violent history
The scale of the battering the Moon received early in its history has been revealed in remarkable new data from two Nasa satellites.
Ebb and Flow - together known as the Grail mission - have mapped the subtle variations in gravity across the surface of the lunar body.
They show the Moon's crust to be a mass of pulverised rock - the remains of countless impacts.
Scientists say the beating was far more extensive than previously thought.

Because of Earth's larger size and higher gravity compared to the Moon it would have been pummeled even worse than the Moon was.
