About

G. Arnold is a key figure in planetary science and instrumentation, specializing in the development of advanced spectrometers for space exploration. Their most significant contribution is the VIRTIS imaging spectrometer aboard ESA’s Rosetta mission, a uniquely complex instrument combining three data channels to study the nucleus and coma of comet 67P/Churyumov-Gerasimenko. This work, published in 2015, has garnered 6 citations and provided groundbreaking first results on the comet’s composition and behavior. Arnold also designed a novel Fourier-transform spectrometer (FTS) for Mars surface operations, featuring a Michelson interferometer with hollow retroreflectors and a single-axis robot for alignment—a 2019 paper with 3 citations that showcases their engineering prowess. Additionally, their 2015 overview of the Rosetta mission’s arrival at 67P (3 citations) highlights their role in coordinating orbiter instruments to map the comet in unprecedented detail. Arnold’s work bridges cutting-edge instrument design and planetary discovery, with their VIRTIS contributions enabling unique observations of a pristine Solar System body. Their achievements underscore a career dedicated to pushing the boundaries of remote sensing in extreme environments.
