O/OREOS (USA 219) — a NASA CubeSat about the size of a loaf of bread that asked one of astrobiology's oldest questions using one of its smallest instruments. Launched November 2010, O/OREOS carried two independent experiments in a single 5.5 kg satellite: one testing whether live microorganisms could survive space's radiation and temperature extremes, the other monitoring how organic molecules — the building blocks of life — degrade when directly exposed to the space environment. It was NASA's first CubeSat ever built to run two completely separate science experiments autonomously, and its six-month mission helped establish that low-cost nanosatellites could deliver genuine astrobiology research, not just technology demonstrations.
