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.
At least two-thirds of Mars' surface is more than 3.5 billion years old, and it could have been habitable 4.48 billion years ago, 500 million years before the earliest known Earth lifeforms; [4] Mars may thus hold the best record of the prebiotic conditions leading to life, even if life does not or has never existed there.

A 2023 study shows evidence, based on the orbital inclination of Deimos (a small moon of Mars), that Mars may once have had a ring system 3.5 billion years to 4 billion years ago. [32] This ring system may have been formed from a moon, 20 times more massive than Phobos, orbiting Mars billions of years ago; and Phobos would be a remnant of that ...
The findings are the latest evidence indicating the existence of this hypothesized ocean, called Deuteronilus, roughly 3.5 to 4 billion years ago, a time when Mars - now cold and desolate ...
Earth may be home to the most glorious beaches in the solar system today, but 3 billion years ago, Mars might have claimed the crown. That’s the conclusion of a new study in the Proceedings of ...
Scientists look forward to an up-close examination of Jerezo's sediments - thought to have formed some 3 billion years ago - in samples collected by Perseverance for future transport to Earth.

The bottom of the Jezero Crater – believed to have formed 3.9 billion years ago from a massive impact – is considered to be among the most promising areas on Mars to search for evidence of ...
