RainCube (Radar in a CubeSat) is a technology demonstration mission to enable Ka-band precipitation radar technologies on a low-cost, quick-turnaround platform. The 6U CubeSat, features a Ka-band nadir pointing precipitation radar with a half-meter parabolic antenna. RainCube first observed rainfall over Mexico in August 2018 and in the following months captured the distinct structures of a variety of storms as well as characteristic signatures of Earth’s surface essential to diagnose pointing and calibration. In this presentation we will focus on the characteristics of the observed scenes, specifically to convey the potential, as well as the limitations, of a radar of this class in addressing the goal of observing weather processes from space.
RainCube (Radar in a CubeSat) is a technology demonstration mission to enable Ka-band precipitation radar technologies on a low-cost, quick-turnaround platform. The 6U CubeSat, currently in orbit, features a radar payload built by the Jet Propulsion Laboratory and a spacecraft bus and operations provided by Tyvak Nano-Satellite Systems. Following the deployment of the half-meter parabolic antenna, the radar first observed rainfall over Mexico. The mission continues to operate and has met all requirements through repeated observations of precipitation in the atmosphere. RainCube is funded through the Science Mission Directorate’s Research Opportunities in Space and Earth Science 2015 In-Space Validation of Earth Science Technologies solicitation. We report on the first radar observations of precipitation.
