    This seems like more of a “last” than a “first” since the reason there is news about it now is that they’re done doing experiments with this device. The NASA article has more detail:

    That device, called MOXIE (Mars Oxygen In-Situ Resource Utilization Experiment), has generated oxygen for the 16th and final time aboard NASA’s Perseverance rover. After the instrument proved far more successful than its creators at the Massachusetts Institute of Technology (MIT) expected, its operations are concluding.

    At its most efficient, MOXIE was able to produce 12 grams of oxygen an hour – twice as much as NASA’s original goals for the instrument – at 98% purity or better. On its 16th run, on Aug. 7, the instrument made 9.8 grams of oxygen. MOXIE successfully completed all of its technical requirements and was operated at a variety of conditions throughout a full Mars year, allowing the instrument’s developers to learn a great deal about the technology.

    The next step wouldn’t be building MOXIE 2.0 – although Hecht and his team have learned a lot about how to design a more efficient version of the instrument. Rather, it would be to create a full-scale system that includes an oxygen generator like MOXIE and a way to liquefy and store that oxygen.
