Technology performance boundaries will be continually pressed as more and more research, operational, and commercial space-based constellations are implemented using CubeSats. In particular, high-speed space-to-earth and inter-satellite communication links, high-impulse propulsion, high-end on-board computation, active thermal control (e.g., cryo-cooling), high-slew rate attitude control, and hyper-spectral microwave and electro-optical sensors and imagers will require higher power satellite resources that furnish 100W OAP (or more) for high cadence or continuous operations. Significant advances in Earth, solar, planetary, and space physics over the next decades will originate from system-level observational techniques. The most promising approach to still be fully developed and exploited requires conducting multi-point or distributed constellation-based observations. This system-level observational approach is required to understand the ?big picture? coupling between disparate regions such as the solar-wind and earth and planetary magnetospheres, ionospheres, upper atmospheres, land, and oceans. CubeSats constellations seem to be the most likely cost-effective way to accomplish the required coverage. The completion of Phase 2 into Phase 3 will result in a CubeSat high power EPS that is robust for use in future NASA missions.
Non-NASA applications include the same list of enabling technologies as provided above for NASA applications. High speed communications will most likely be the driver for requiring higher power and motivating use of our system by commercial actors. We anticipate that these capabilities will drive interest in the high-power system in the commercial sector as well as the department of defense. The DoD will be interested in fast slew rates and cryo-cooling enabled by our high-power CubeSat system. ASTRA is involved in several commercial CubeSat ventures that would benefit from the HPoCCS development.
