NASA leaders argued that it makes more sense to uncover problems and practice operations close to home, in Earth orbit, rather than discovering them for the first time while attempting a landing on the moon. If the faster launch tempo holds, Artemis IV and Artemis V together could give NASA two opportunities in 2028. Officials stressed that the timeline still depends on hardware readiness and safety reviews.

This was not the first time that microbiologists experienced problems with agar. A phenomenon called “The Great Plate Count Anomaly” baffled researchers in the early 20th century when they observed that the number of cells seen under a microscope didn’t match the actual number of colonies growing on an agar plate. Investigating this discrepancy, researchers found agar itself to be the culprit: when nutrient broths are heated with agar during boiling, harmful byproducts (hydroperoxide) can form due to the reaction of agar with phosphate minerals contained in the media. Researchers can avoid this by autoclaving agar separately from the nutrient broth, or by reducing the amount of agar used.
