Pre-Noachian: the interval from the accretion and differentiation of the planet about 4.5 billion years ago to the formation of the Hellas impact basin, between 4.1 and 3.8 Gya. [13] Most of the geologic record of this interval has been erased by subsequent erosion and high impact rates.
Into the early 20th century, additional observations of Mars fed people's interest in what was called "Mars fever". [ 1 ] [ 2 ] One of the earliest films to be set on Mars was the short film A Trip to Mars (1910), which was produced by one of Thomas Edison 's film companies. [ 3 ]

The geologic time scale is a way of representing deep time based on events that have occurred throughout Earth's history, a time span of about 4.54 ± 0.05 Ga (4.54 billion years). [3] It chronologically organises strata, and subsequently time, by observing fundamental changes in stratigraphy that correspond to major geological or ...
The Mars carbonate catastrophe was an event that happened on Mars in its early history. Evidence shows Mars was once warmer and wet about 4 billion years ago, that is about 560 million years after the formation of Mars. Mars quickly, over a 1 to 12 million year time span, lost its water, becoming cold and very dry.
