Other Artemis Co-Investigators:
The
Artemis E-TLS (evolved gas measurements) will:
•
Determine the amount of water (H2O) and carbon dioxide (CO2)
adsorbed in Martian soil, and their release temperatures.
•
Determine the amount of H2O and CO2 chemically-bound as minerals.
•
Determine the adsorption isotherms of Martian soil, and the mineral phases that
store H2O and CO2.
•
Measure the 13C/12C and 18O/16O isotopic ratios in CO2 adsorbed or evolved from soil samples.
The
Artemis A-TLS (atmospheric measurements) will:
•
Determine the near-surface atmospheric abundances of H2O
and CO2
•
Measure the 13C/12C and 18O/16O isotopic ratios in CO2 present in the Martian atmosphere
•
Compare atmospheric with evolved gas isotopic ratios to assess the extent of
equilibrium between atmospheric CO2 and that bound in carbonates
•
Monitor near-surface atmospheric variations in both H2O
and CO2
abundances that may result from diurnal or seasonal changes
