Abstract

Feedback from massive stars through their host galaxies is a crucial driver of galaxy evolution, energizing and enriching the interstellar medium (ISM) and circumgalactic medium (CGM). Massive stars also emit ionizing radiation, a fraction of which escapes into the intergalactic medium. The Supernova Remnants and Proxies for Reionization Testbed Experiment (SPRITE) is a 12U CubeSat that will observe these processes in the far-ultraviolet in local galaxies through two independent but related science surveys. SPRITE is the first independent far-UV orbital spectroscopic mission in over 20 years, and the first orbital instrument capable of sub-arcminute imaging spectroscopy in the Lyman ultraviolet (91 < λ < 120 nm). We present the results of ground testing of the SPRITE flight instrument and characterize its projected on-orbit performance. We also demonstrate the capabilities of SPRITE’s unique technological developments, including advanced UV optical coatings and a low-background microchannel plate detector, providing flight heritage for Habitable Worlds Observatory (HWO) and other future missions.
