Abstract Organic matter in the Martian sediments may provide a key to understanding the prebiotic chemistry and habitability of early Mars. The Curiosity rover has measured highly variable and 13C-depleted carbon isotopic values in early Martian orga

Abstract Formaldehyde (H2CO) is a critical precursor for the abiotic formation of biomolecules, including amino acids and sugars, which are the building blocks of proteins and RNA. Geomorphological and geochemical evidence on Mars indicates a tempera

Over the past few decades, numerous geochemical and geological observations of early Mars have suggested the presence of surface river systems during the late Noachian and early Hesperian. A large volume of liquid water combined with stable and long-

Martian water channels are considered evidence of a climate warm enough to allow the existence of long-term fluvial systems on early Mars during the Noachian and Hesperian boundary (3.85–3.6 Ga). Quantitative inferences of water channel formation f
