What do you think Mars looked like in the ancient past?

a lot of depictions show it looking like it does now but with oceans:

The problem with this is that the surface was likely initially dark grey due to being covered by ultramafic rocks. These eventually turned red when the iron in them was oxidised, forming rust. 4 billion years ago, Mars probably looked more like this:

Although by 3.5 billion years ago, large parts of the surface probably started to have a rusty brown colour and clouds would be sparser.

Imagining ancient Mars is truly fascinating. Initially, Mars was likely a dark grey planet due to its ultramafic rock surface. With time, the iron in those rocks oxidized, leading to the distinct rusty red hue we associate with Mars today. Around 4 billion years ago, the planet transformed from that dark grey to a reddish-brown as oxidation took place. It's believed there was once water on Mars, so visualizing it with oceans beneath a partly cloudy sky is a captivating idea. 🪐
