CubeSats are enabled by the enormous investment of the commercial, medical, and defense industries in producing highly capable, portable and low-power battery-operated consumer electronics, in-situ composition probes, and novel reconnaissance sensors. Significant progress has been made by the nascent CubeSat industry in demonstrating, on orbit, the viability of CubeSats for a variety of tasks. A constellation of spacecraft for space weather purposes can now be created and deployed from a single launch vehicle with a variety of sensors for observing the state of the space environment. This reality has been demonstrated by the successes of commercial companies in deploying and operating a constellation of more than 150 satellites. The space weather community has embraced the concept of CubeSat constellations but the actual application of them is still only a concept in study. In this talk we overview the current capability of CubeSats and the direction of innovations and advancements within the CubeSat industry and concepts for how they can be used to address priority space weather research topics.
