    On April 21, 2021, Jim Reuter, the Associate Administrator for STMD explained that the experiment was functioning with results having many uses, stating: "This is a critical first step at converting carbon dioxide to oxygen on Mars. MOXIE has more work to do, but the results from this technology demonstration are full of promise as we move ...

    An instrument the size of a lunchbox has proven it can do the work of a small tree by successfully generating oxygen on the dusty surface of Mars. The instrument — called the Mars Oxygen In-Situ ...

  6. Photosystem II - Wikipedia

    en.wikipedia.org/wiki/Photosystem_II

    The oxygen-evolving complex is the site of water oxidation. It is a metallo-oxo cluster comprising four manganese ions (in oxidation states ranging from +3 to +4) [ 6 ] and one divalent calcium ion. When it oxidizes water, producing oxygen gas and protons, it sequentially delivers the four electrons from water to a tyrosine (D1-Y161) sidechain ...

    en.wikipedia.org/wiki/Photosynthesis

    Some shade-loving plants (sciophytes) produce such low levels of oxygen during photosynthesis that they use all of it themselves instead of releasing it to the atmosphere. [ 12 ] Although there are some differences between oxygenic photosynthesis in plants, algae, and cyanobacteria, the overall process is quite similar in these organisms.

    It is hoped that at full capacity, the system should generate enough oxygen to sustain humans once they arrive on Mars. It is hoped that at full capacity, the system should generate enough oxygen ...

  9. Dark oxygen - Wikipedia

    en.wikipedia.org/wiki/Dark_oxygen

    Dark oxygen production refers to the generation of molecular oxygen (O 2) through processes that do not involve light-dependent oxygenic photosynthesis.The name therefore uses a different sense of 'dark' than that used in the phrase "biological dark matter" (for example) which indicates obscurity to scientific assessment rather than the photometric meaning.
