Headline Details: The Supernova remnants Proxies for Reionization and Integrated Testbed Experiment (SPRITE) CubeSat is a 12U CubeSat designed to carry out two science objectives. SPRITE will spend roughly half of the projected two-year baseline mission mapping shock emission in supernova remnants in the Milky Way and Magellanic Clouds, and the other half determining the escape fraction of hydrogen ionizing radiation from 100 low-redshift starforming galaxies. In parallel with the science operations, SPRITE will execute a calibration program that will track the stability of the mirror coatings and detector over the mission lifetime. SPRITE will operate similar to our prior cubesats (CSSWE, MinXSS-1, MinXSS-2, QB-50 Challenger, CSIM, CUTE and CIRBE) which have gathered over 100 MB of data from amateur operators and were all coordinated by the IARU. As has been the case in the past, we will be actively soliciting the telemetry from amateurs. The information provided by amateurs has been crucial for past missions, enabling us to detect instrument orbits and the Doppler-shifted communication frequencies and troubleshoot anomalies. It is common for all of our missions to have extensive student involvement during the design, building, testing, and operation of the instrument. We take the training of next generation scientists and engineers very seriously. Our students will continue to be trained in the art of satellite communications, space weather, spacecraft design and operations. All students working on our cubesat projects are strongly encouraged to pursue their radio amateur license if they are not already licensed. Due to SPRITE’s nature as an education and research mission, much of the research work is done by undergraduate and graduate students. This work is invaluable to students as they learn and become well versed in satellite system design, communication testing and scientific analysis. In working on the project, these students become knowledgeable and appreciative of the amateur radio art and get exposed to the radio amateur community. We encourage all students working on the project to pursue the amateur radio license. Proposing a UHF downlink using 19k2 GMSK with AX25 and on S Band using CCSDS packets with 4 Mbps BPSK.
