We are developing a low-cost hyperspectral sensor to trial in low-Earth orbit for consideration on deep space cubesat missions. Our design proposes to use a commercial off the shelf sensor and dispersive optics controlled by a programmable gate array to produce visible/near infra-red spectra within a 1U-sized unit. Auxiliary imagers are being considered to provide context imagery for captured spectra, as well as a backup to the primary sensor. Systems engineering trade studies have been conducted to inform sensor choice in a COVID-constrained environment. Ground-based testing of a prototype design using minerals commonly found on the surface of Mars has demonstrated utility of this sensor for off-Earth applications. Near-space testing using high-altitude ballooning is planned to be conducted to inform survivability of components in a Mars-like environment, and refine the final design.
