Compact Ultraviolet to Visible Imaging Spectrometer (CUVIS) Technology Demonstration onboard the DAVINCI Mission to Venus, NASA Discovery Mission, Institutional Principal Investigator
Design, build, test and validate a Compact Ultraviolet to Visible Spectrometer (CUVIS), an innovative dual-band dispersion and imaging spectrometer with spectral range 200–570 nm, that will complement the science obtained from DAVINCI's VISOR UV Camera. The spectrometer’s primary goal is to investigate radiative balance, cloud properties and chemistry of Venus’s atmosphere, address the vexing scientific problem of the unknown UV absorber(s) at the cloud tops; secondary goals include cloud top habitability, and to gain insight into slow rotating hot exoplanets by using Venus as a test case.
Modular Infrared Molecules and Ices Sensor (MIRMIS), ESA F-Class Comet Interceptor Mission, Co-Investigator
MIRMIS covers the spectral range 0.9 to ~25 μm and will map the ice, mineral, and gas composition ofthe target’s nucleus and coma and the distribution of surface temperatures on the nucleus.
Ice Particle Counter for Ocean World Plume-Flyby Missions, FY22 IRAD, Principal Investigator
Develop an enabling technology that will count water-ice particles while flying through the plume of Enceladus or Europa.
Ultra-Violet Detector Innovation for Raman Exploration and CharacTerization (UV-DIRECT) of Ocean Worlds, NASA ROSES PICASSO, Co-Investigator
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.
RAMS: RAman-Mass Spectrometer for planetary exploration, NASA ROSES PICASSO, Co-Investigator
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.
Characterization of the CUVIS spectrometer: maturation of a multi-mission radiation-hard CMOS-based camera assembly and breadboard integration, FY22, Co-Investigator
Develop in-house capability on the broad spectral response NUV-NIR Teledyne space-qualified CMOS image sensor.
Design, Fabrication and Testing of Metal-Mesh Linear Variable Filters for Planetary Remote Sensing Instrumentation, FY22 IRAD, Co-Investigator
Demonstrate metal mesh based LVFs for the 12.5 mm to 25 mm band to improve measurements of surface temperature, emissivity, multi-spectral image maps, porosity, and material composition identification for remote sensing planetary missions.
Time Resolved Spatial Heterodyne Raman Spectrometer, FY22 IRAD, Co-Invetigator
Demonstrate a novel high resolution, high throughput, time resolve Spatial Heterodyne Spectrometer (SHS) for planetary science applications.
