The High-Resolution Spectroscopic Imaging Mission is designed to be the first instrument to make true images of the hard X-ray/soft gamma-ray (2 - 600 keV) sky. By focusing energetic X-rays and low-energy gamma-rays, HSI will observe the cosmos with an unprecedented combination of sensitivity, spectral resolution, and angular resolving power. HSI is based on an array of multilayer grazing-incidence optics focusing onto high-resolution solid-state germanium pixel detectors with a focal length of 30 - 50 m. This paper describes the primary scientific objectives, technical approach to the instrumentation, and mission design.
