We present the design for a rocket-borne narrow-band far-ultraviolet imaging telescope. It will measure the spatial distribution of photo-excited molecular hydrogen emission nearby hot stars by utilizing multi-layer reflection coatings, similar to those used in previous NASA experiments, to obtain two images during a flight: one with a narrow-band filter that captures the 1575/1608A emission features (the "on-band" filter), and a second one that measures the dust-scattered stellar continuum at 1800A (the "off-band" filter). The difference image will then isolate the molecular hydrogen emission by subtracting the underlying scattered-light background. This would be a large improvement over existing studies at ultraviolet wavelengths for which many individual pointings with spectroscopic apertures are required to map the region of interest. These data will complete the picture, combined with far-ultraviolet spectra and near-infrared observations of vibrational emission that we will obtain from ground-based instrumentation, of the physical conditions in sites of recent and on-going star formation. A sounding rocket payload such as this provides the opportunity to perform niche science that other facilities cannot as well as advances the readiness of junior researchers to assume leadership roles on future NASA space flight missions.
