CERES

CERES is mission control for the first farm off Earth: a crop-health copilot for a spacecraft greenhouse. Fresh crops will supplement astronaut diets on long missions, but crew time is scarce, and a plant that wilts overnight is easy to miss. On Mars, a question to Earth takes 3–22 minutes each way. A crop-health system there has to do five things: Measure plants itself. Raise alerts without a model guessing. Explain each alert with evidence a human can check. Keep working when the Earth link is down. Never act on its own.
