Thermodynamic model of Mars Oxygen ISRU Experiment (MOXIE)

Mars Brine Formation Experiment

The Mars oxidant experiment (MOx) for Mars '96.

The MOx instrument was developed to characterize the reactive nature of the martian soil. The objectives of MOx were: (1) to measure the rate of degradation of organics in the martian environment; (2) to determine if the reactions seen by the Viking biology experiments were caused by a soil oxidant and measure the reactivity of the soil and atmosphere: (3) to monitor the degradation, when expos...

Observations of the nightside ionosphere of Mars by the Mars Express Radio Science Experiment (MaRS)

[1] The vertical structure of the nightside ionosphere of Mars and its dependence on solar zenith angle are currently poorly determined, as is the importance of two key sources of nightside plasma, electron precipitation and transport of dayside plasma. We examined 37 electron density profiles of the ionosphere of Mars at solar zenith angles of 101 –123 obtained by the Mars Express Radio Scienc...

Wet Chemistry Experiment at Mars (wetchem)

Introduction: NASA is developing strategies for several in-situ missions to Mars in the next few decades to explore and quantitatively assess potential habitability on Mars. Some of these missions will be designed to specifically search for biosignatures on Mars. Much of the present practice in the development of new detection technologies and instrumentation for astrobiology follows the model ...

Timing of acid weathering on Mars: A kinetic-thermodynamic assessment

[1] Weathering of olivine basalt by H2SO4-HCl aqueous solutions at the conditions of early Mars was investigated through numerical modeling in a system open with respect to CO2 and O2 only. The model includes dissolution rates of primary and secondary minerals and oxidation rate of aqueous Fe, as well as chemical equilibration among solutes, dissolved gases, and precipitates. The results reveal...
