Lunar Flashlight is a low-cost mission to be launched as part of NASA’s first SLS flight. This innovative mission will demonstrate several firsts, including being one of the first instruments onboard a CubeSat performing science measurements beyond low Earth orbit, and the first planetary mission to use multiband active reflectometry from orbit. It will demonstrate new 100 mN thrusters using green propellant, providing nearly 25% higher performance than hydrazine in a low toxicity form for transport and storage. Lunar Flashlight will drive infusion of these technologies into smaller satellites and payloads for NASA. Lunar Flashlight’s four-channel laser projector will illuminate PSRs, measuring surface reflectance at wavelengths diagnostic of water ice. Lunar Flashlight will attempt to distinguish water ice from dry regolith in two ways: 1) spatial variations in albedo and 2) reflectance ratios between absorption and continuum channels.
