| contents | The Star-Planet Activity Research CubeSat (SPARCS) is a NASA-funded 6U-CubeSat mission designed to monitor ultraviolet (UV) radiation from low-mass stars. These stars' relatively high-frequency and high-energy UV flares significantly affect the atmospheres of orbiting exoplanets, driving atmospheric loss and altering the conditions for habitability. SPARCS aims to capture time-resolved photometric data in the far-UV and near-UV simultaneously to better characterize the flares and detect the strongest and rarest among them. In addition, SPARCS is testing innovative technology, such as delta-doped detectors with near 100% internal quantum efficiency and detector-integrated metaldielectric UV bandpass filters. This mission will increase the technology readiness level of these critical components, positioning them for inclusion in future flagship missions like the Habitable Worlds Observatory. This paper outlines SPARCS' mission goals and provides an update as the spacecraft is completed and awaits its planned late-2025 launch to a sun-synchronous low-Earth orbit. It also highlights the critical role of small missions in providing training and leadership development opportunities for students and researchers, advancing technology for larger observatories, and shares lessons learned from collaborations between academic, government, and industry partners. |
