jsc2019e056550 (9/27/2019) --- Preflight view of Argus-02 awaiting integration at the NanoRacks facility. Argus-02 has two objectives: to examine the effect of space radiation on electronics and to test machine-learning algorithms that identify natural events. Memory cards loaded with known images are exposed to space radiation to further study radiation-induced effects. Simultaneously, the CubeSat images the Earth limb and uses algorithms to identify events such as lightning strikes and auroras; false-positive identification of events leads to modification of algorithms. Argus-02 results may help improve electronics and software for future space travel. Image courtesy of: Saint Louis University
