NASA's suborbital program provides an opportunity to conduct unique scienceexperiments above Earth's atmosphere and is a pipeline for the technology andpersonnel essential to future space astrophysics, heliophysics, and atmosphericscience missions. In this paper, we describe three astronomy payloads developed(or in development) by the Ultraviolet Rocket Group at the University ofColorado. These far-ultraviolet (100 - 160 nm) spectrographic instruments areused to study a range of scientific topics, from gas in the interstellar medium(accessing diagnostics of material spanning five orders of magnitude intemperature in a single observation) to the energetic radiation environment ofnearby exoplanetary systems. The three instruments, SLICE, CHESS, and SISTINEform a progression of instrument designs and component-level technologymaturation. SLICE is a pathfinder instrument for the development of new datahandling, storage, and telemetry techniques. CHESS and SISTINE are testbeds fortechnology and instrument design enabling high-resolution (R > 100,000) pointsource spectroscopy and high throughput imaging spectroscopy, respectively, insupport of future Explorer, Probe, and Flagship-class missions. The CHESS andSISTINE payloads support the development and flight testing of large-formatphoton-counting detectors and advanced optical coatings: NASA's top twotechnology priorities for enabling a future flagship observatory (e.g., theLUVOIR Surveyor concept) that offers factors of roughly 50 - 100 gain inultraviolet spectroscopy capability over the Hubble Space Telescope. We presentthe design, component level laboratory characterization, and flight results forthese instruments.
