Headline Details: A 2U CubeSat. The space radiation environment in Earth’s atmosphere is filled with hot and low-density plasmas that can cause charge to build up on spacecraft surfaces, resulting in high differential voltages and subsequent electrostatic discharges. These discharges can damage avionics and/or scientific instruments on spacecraft. SurfSat will take in-situ measurements of the ground current waveforms from chosen common spacecraft dielectric material samples, measure the spacecraft and material potentials, and will use a Langmuir probe system to measure the ambient plasma environment. The sample materials will span a range of resistivities that will be chosen both for relevance and in order to maximize scientific return. Comparison of on-orbit ESD measurements with completed and ongoing plasma chamber charging experiments will be used to validate current plasma charging test methods. These experiments will be used to develop design criteria, and help avoid potentially disastrous discharging on spacecraft. This spacecraft, including the hardware, electronics, and software, is designed and built primarily by students at the University of Central Florida. Proposing a 9k6 FSK downlink on 435.275 MHz. Planning a launch from Vandenberg in September 2018 together with ELFIN & DAVE. **The downlink frequency of 437.275 MHz has been coordinated**
Application Date: 20 Feb 2018   Freq coordination completed on 18 Jun 2018
