Schematic outlining the process through which H could be sequestered into ECs. Firstly, submicron FeS grains that become coated in dust particles in the solar nebula are transformed into pyrrhotite

Scytonemin structure – Wikipedia Scytonemin, a UV-protective pigment produced by cyanobacteria, is essential for microbial survival under extreme solar radiation. Recent studies suggest its structural analog, scytonemin imine, may serve

Reflected total normalized flux πFn (left panel) and signed degree of linear polarization Ps (right panel) as functions of the planetary phase angle α and wavelength λ for our Hadean:

Schematic illustration of our proposed carbon cycle on early Mars. Evaporation of water (pink shading) from subsurface pore spaces initially deposits siderite, which sequesters atmospheric CO2 (black downward arrow). Increasing
