Development of infra-red radiometers and Fourier transform spectrometers for remote sensing of planetary atmospheres.
Development of advanced net flux radiometers for studying the atmospheric (thermal) structure of planetary atmospheres, in particular to, (i) determine the planet’s atmospheric heat balance and (ii) determine the planet’s tropospheric 3-D flow.
Development of instrumentation to carry out in-situ time-resolved Raman and photoluminescence (PL) spectroscopy, of samples collected from planetary regoliths, to discover, if present, the types and distribution of biotic and abiotic organic compounds, measure CHNOPS containing organics and minerals and correlate them to radiolysis processed and textural features.
Ultra-Violet Detector Innovation for Raman Exploration and CharacTerization (UV-DIRECT) of Ocean Worlds enables the identification of minerals, volatiles, organic molecules, biopolymers, water, and other hydrous phases in planetary materials with the added bonus of Raman spectroscopic imaging.
Raman-Mass Spectrometer (RAMS) instrument suite incorporates laser desorption/ ionization mass spectrometry (LDMS) and micro Raman microspectroscopy imaging (μRS) into a compact instrument package with shared resources realizing size, weight and power (SWaP) savings over two separate instruments, while simultaneously enabling comprehensive sample analysis capabilities transcending those of either technique alone.
