About

Stephen P. Sandford is a leading figure in the development of advanced laser-based remote sensing instruments for planetary science and astrobiology. His research focuses on creating compact, multi-functional spectrographic systems that integrate Raman spectroscopy, laser-induced fluorescence (LIF), laser-induced breakdown spectroscopy (LIBS), and lidar into a single, powerful payload. Sandford’s major contribution is the conceptualization and prototyping of these "multisensing" instruments, which are designed to simultaneously characterize the mineralogy, organic chemistry, and atmospheric properties of planetary surfaces and atmospheres from a distance. His 2015 paper on a laser remote sensing instrument for astrobiology detection (30 citations) demonstrates the high-fidelity scientific return of such integrated systems, while his 2013 work on a compact remote multisensing instrument (9 citations) established the feasibility of a prototype suitable for spaceflight. By enabling the detection of trace organics and specific minerals at low concentrations, Sandford’s work directly supports the search for biosignatures on targets like Jupiter’s icy moons and Mars, positioning him as a key innovator in the next generation of planetary exploration tools.
