Martian soil
Martian soil is the fine regolith found on the surface of Mars . Its properties can differ significantly from those of terrestrial soil , including its toxicity due to the presence of chlorine . The term Martian soil typically refers to the finer fraction of regolith. On Earth, the term "soil" usually includes organic content. [1] In contrast, planetary scientists adopt a functional definition of soil to distinguish it from rocks. [2] Rocks generally refer to 10 cm scale and larger materials (e.g., fragments, breccia , and exposed outcrops) with high thermal inertia, with areal fractions consistent with the Viking Infrared Thermal Mapper (IRTM) data, and immobile under current aeolian conditions. [2] Consequently, rocks classify as grains exceeding the size of cobbles on the Wentworth scale .

Martian soil is the fine regolith found on the surface of Mars . Its properties can differ significantly from those of terrestrial soil . The term Martian soil typically refers to the finer fraction of regolith. On Earth, the term "soil" usually includes organic content. [1] In contrast, planetary scientists adopt a functional definition of soil to distinguish it from rocks. [2] Rocks generally refer to 10 cm scale and larger materials (e.g., fragments, breccia, and exposed outcrops) with high thermal inertia, with areal fractions consistent with the Viking Infrared Thermal Mapper (IRTM) data, and immobile under current eolian conditions. [2] Consequently, rocks classify as grains exceeding the size of cobbles on the Wentworth scale . This approach enables agreement across Martian remote sensing methods that span the electromagnetic spectrum from gamma to radio waves . ‘‘Soil’’ refers to all other, typically unconsolidated, material including those sufficiently fine-grained to be mobilized by wind. [2] Soil consequently encompasses a variety of regolith components identified at landing sites. Typical examples include: bedform armor, clasts, concretions, drift, dust, rocky fragments, and sand. The functional definition reinforces a recently proposed genetic definition of soil on terrestrial bodies (including asteroids and satellites ) as an unconsolidated and chemically weathered surficial layer of fine-grained mineral or organic material exceeding centimeter scale thickness, with or without coarse elements and cemented portions.

Martian soil is the fine regolith found on the surface of Mars . Its properties can differ significantly from those of terrestrial soil . The term Martian soil typically refers to the finer fraction of regolith, that which is composed of grains one centimeter in diameter or less. Some have argued that the term "soil" is not correct in reference to Mars because soil is defined as having organic content, whereas Mars is not known to have such content. However, standard usage among planetary scientists is to ignore that distinction. |
