Five-O is a diverse group of investigators that view science questions from a broad range of perspectives and a diverse knowledge base. The interdisciplinary team is interconnect by four major themes.
Our four themes:
- Experiments and modeling: This theme will study regolith (soil) formation under extreme lunar conditions and investigate the origin(s) and evolution of polar ices. Experiments and modeling will provide the insight necessary to accurately determine volatile source(s) by in-situ isotopic measurements. In addition, we will characterize physical, spectral, and chemical signatures of volatile ices, lunar minerals and glasses, and their interactions with each other under relevant conditions.
Volatile Transport and Modification
Modeling transport effects on composition
- Analytical Characterization of Volatile Exposed Materials will characterize samples from experiments and Interplanetary dust particles using: Electron microprobe, Scanning TEM, Secondary Ion Spectrometry nano FTIR, reflectance spectra from UV to NIR, magnetic properties, Laser Raman spectroscopy
to assess the sub-micron infrared spectroscopic changes (in absorption spectra and dielectric constant) in laboratory space-weathered materials produced
Transmission Electron Microscopy
NanoSIMS measurements to measure water contents in FIB sections
- Remote Sensing—detection and quantification of organics and understanding the interplay of reflectance and thermal emission that confounds estimates of water abundance on the lunar surface.
- Sample Curation & Handling of cryogenic samples—will develop methodologies for maintaining, storing and handling pristine, sterile samples at cryogenic temperatures.
