Also in the Solar Moth based "robot asteroid prospector" architecture, where concentrated solar provided triple duty as power, heat (needed to melt the water in iceteroids), and water-prop thermal propulsion. The study suggests that a solar moth with water propellant can get about 450 seconds of Isp at 1AU, which is actually better than NASA's current water propellant solid core NTP designs.
