Radiation limits on amino acid preservation and chiral measurement at Oxia Planum

Dimitra Atri

Amino acid enantiomeric excess (EE) is a potential biosignature, but its measurement requires sufficient surviving material as well as preserved chirality. We derive a criterion th…

Energy-Limited Radiolytic Habitability in the Shallow Martian Subsurface: Implications for ExoMars Rosalind Franklin and Tianwen-3

Dimitra Atri

The surface of Mars is sterilized by ionizing radiation and pervasive oxidants; its shallow subsurface, shielded from ultraviolet light and the most reactive oxidation, may instead…

Radiation protection and shielding materials for crewed missions on the surface of Mars

Dionysios Gakis, Dimitra Atri

A potential crewed mission to Mars would require us to solve a number of problems, including how to protect astronauts against the devastating effects of energetic charged particle…

Auroras on Mars: from Discovery to New Developments

Dimitra Atri, Dattaraj B. Dhuri, Mathilde Simoni +1

Auroras are emissions in a planetary atmosphere caused by its interactions with the surrounding plasma environment. They have been observed in most planets and some moons of the so…

Crewed Missions to Mars: Modeling the Impact of Astrophysical Charged Particles on Astronauts and Their Health

Dimitra Atri, Caitlin MacArthur, Sriram Devata +8

The impact of exposure to astrophysical ionizing radiation on astronaut health is one of the main concerns in planning crewed missions to Mars. Astronauts will be exposed to energe…

Estimating the potential of ionizing radiation-induced radiolysis for microbial metabolism on terrestrial planets and satellites with rarefied atmospheres

Dimitra Atri, Margaret Kamenetskiy, Michael May +3

Ionizing radiation is known to have a destructive effect on biology by causing damage to the DNA, cells, and production of Reactive Oxygen Species (ROS), among other things. While…
