Poster Session: Astrobiology and Exobiology

Wednesday, March 15, 2023, 6:30 PM

Nascimento-Dias B. L.*
Is the Use of Financial Resources in Astrobiology Research Justifiable? [#1080]
The main objective here is to raise some philosophical reflections on the feasibility of using financial resources in astrobiology research.
Nascimento-Dias B. L.*
A Brief History and Philosophical Reflections on the Terms Astrobiology, Exobiology, Cosmobiology, Xenobiology, and Bioastronomy [#1082]
The main idea here is to present reflections on the terms that exist and name this field of research in the search for extraterrestrial life.
Cortez P. M.* Perl S. M.
Astrobiological Assessment of Geobiological Features Within Habitable Environments: Developing the Geobiological Handbook of Measurements for Life Detection [#2334]
The purpose of this paper is to show the development of the GHMLD and how this handbook outlines the usage of instrument techniques for life detection.
Shahid A. M.* Sheng T. Murray J. B. Mishra A. Czaplinski E. C. et al.
Statistical Classification of Biosignature Information: Improving Life-Detection Confidence Using Machine Learning [#2800]
The SCOBI project uses terrestrial data from biogenic and abiogenic systems to create a binary classifier for life detection and assess feature importance.

Spectral Characterization of Halophiles Isolated from Hypersaline Environments Relevant to Mars and Ocean Worlds [#1689]
Pigmented halophiles were examined for spectral differences between strains and to search for spectrally diagnostic biomolecules using spacecraft relevant tools.

Spectral Characteristics of Potential Complex Oxalate on Mars and Implication for Mars Missions [#1414]
In this study, we synthesized phoxite from chemical reagents, then collect the mid-infrared and Raman spectra of synthesized samples.
Henderson B. L.* Abrahamsson V. Prothmann J. Zhong F. Lin Y. et al.
A New Approach to Sensitive Analysis of Resilient Biomaterials [#1734]
Optimization of protocols for our SCHAN instrument reveals that simple treatments can improve the odds of life-detection in future in-situ mission applications.
De Sanctis M. C.* Altieri F. De Angelis S. Ferrari M. Frigeri A. et al.
Ma_MISS on Rosalind Franklin Rover Actvities for the Exploration of the Martian Surface and Subsurface [#1947]
We describe the scientific activities to support martian exploration in the context of the Rosalind Franklin rover, specifically for the Ma_MISS instrument.
