Testing Abiotic Reduction of NAD+ Directly Mediated by Iron/Sulfur Minerals
Autor: Keith J. Billings, Scott Perl, Laura M. Barge, Jessica M. Weber, Aaron David Goldman, Douglas E. LaRowe, Bryana L. Henderson
Publikováno v: Astrobiology. 22:25-34
Life emerged in a geochemical context, possibly in the midst of mineral substrates. However, it is not known to what extent minerals and dissolved inorganic ions could have facilitated the evolutio...

3D Printed Minerals as Astrobiology Analogs of Hydrothermal Vent Chimneys
Autor: Pate Andre M, John Bescup, Laura M. Barge, Samad Firdosy, Roy E. Price, Scott Perl, Xu Zhang, John-Paul Jones
Publikováno v: Astrobiology. 20:1405-1412
Hydrothermal vents, which are highly plausible habitable environments for life and of interest for some origin-of-life scenarios, may exist on icy moons such as Europa or Enceladus in addition to Earth. Some hydrothermal vent chimney structures are e

0.25 Ga Salt Deposits Preserve Signatures of Habitable Conditions and Ancient Lipids
Autor: Mary Beth Wilhelm, Sean Paling, Thomas W. D. Edwards, Sam Payler, Jennifer Wadsworth, Scott Perl, Charles S. Cockell, Sean McMahon
Publikováno v: Astrobiology. 20:864-877
Polygonal features in a ∼250 million-year-old Permian evaporitic deposit were investigated for their geological and organic content to test the hypothesis that they could preserve the signature of ancient habitable conditions and biological activit

Habitability of Martian Noachian Hydrothermal Systems as Constrained by a Terrestrial Analog on the Colorado Plateau
Autor: N. Castle, Sally L. Potter-McIntyre, Justin Filiberto, J. R. Crandall, Susanne P. Schwenzer, Karen Olsson-Francis, Scott Perl
Volcanic features and impact craters are ubiquitous features on Mars, and hydrothermal systems associated with the production of these features should have been abundant in Mars’s early history. These hydrothermal systems represent potentially habi

Thermal Analysis of Landers using Radioisotope Power Systems on Ice Worlds
Autor: Scott Perl, Young H. Lee, Benjamin Donitz, Mathieu Choukroun, Sam Howell, Brian Bairstow
Publikováno v: 2021 IEEE Aerospace Conference (50100).
The surfaces of icy worlds record evidence of interior processes, chemical potential, habitability, and potentially life within the interior. Volatile and organic chemistry at the surface is critical in determining habitability and detecting the pres

Habitability of Hydrothermal Systems at Jezero and Gusev Craters as Constrained by Hydrothermal Alteration of a Terrestrial Mafic Dike
Autor: Sally L. Potter-McIntyre, Daniel R. Hummer, Karen Olsson-Francis, Michael A. Miller, Justin Filiberto, J. R. Crandall, Scott Perl, L. J. Costello, Susanne P. Schwenzer
Publikováno v: Chem Erde
NASA’s search for habitable environments has focused on alteration mineralogy of the Martian crust and the formation of hydrous minerals, because they reveal information about the fluid and environmental conditions from which they precipitated. Ext
