Late Heavy Bombardment (lunar cataclysm): hypothetical event around 4.1 to 3.8 billion years ago; a large number of impact craters on the Moon would have formed & also on Earth, Mercury, Venus & Mars; late in the Solar System's accretion period when Earth & the other rocky planets formed & gained most of their mass; new research casts doubt on this theory

#Mars #Space – Mars Had Surprising 400-Million-Year Lull Between Giant-Impact Eras : Mars enjoyed about 400 million years of relative peace between two giant-impact epochs long ago, a new study suggests. Researchers determined that there were likely no gigantic impacts on the Red Planet between about 4.5 billion years ago and the “Late Heavy Bombardment” …

The Hadean, being an informal not stratigraphically defined eon, is here defined as the period from the Tellus (proto-Earth)-Theia impact (circa 4520 mya) to the end of the LHB (Late Heavy Bombardment) period,about 3800 bya. Recently, Goldblatt et al. 2010 have proposed an even earlier eon, the Chaotian,for events pertaining to the formation of the Solar System

Ganymede and Callisto’s evolutionary paths diverged about 3.8 billion years ago during the Late Heavy Bombardment, the phase in lunar history dominated by large impact events.

Incoming! The LHB probably lasted a lot longer than previously thought, with some really big blasts, too.
