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…
Assessment of Microbial Habitability Across Solar System Targets
Dimitra Atri, Todd Godderidge, Dee Cirium +2
With a fleet of exploratory space missions on the horizon, the study of target specific biospheres is crucial for accurately determining the probability of the existence of microbi…
Habitability Models for Astrobiology
Abel Méndez, Edgard E. Rivera-Valentín, Dirk Schulze-Makuch +31
Habitability has been generally defined as the capability of an environment to support life. Ecologists have been using Habitat Suitability Models (HSMs) for more than four decades…
Modeling Solar Proton Event-induced Martian Surface Radiation Dose
Dimitra Atri, Caitlin MacArthur, Ian Dobbs-Dixon
Solar Proton Events (SPEs) can cause abrupt and significant enhancements to the Martian surface radiation dose. Observations of the impact of SPEs on the Martian surface are availa…
Gamma Ray Bursts: Not so Much Deadlier than We Thought
Brian C. Thomas, Dimitra Atri, Adrian L. Melott
We analyze the additional effect on planetary atmospheres of recently detected gamma-ray burst afterglow photons in the range up to 1 TeV. For an Earth-like atmosphere we find that…
Stellar Flares versus Luminosity: XUV-induced Atmospheric Escape and Planetary Habitability
Dimitra Atri, Shane R. Carberry Mogan
Space weather plays an important role in the evolution of planetary atmospheres. Observations have shown that stellar flares emit energy in a wide energy range (10^30-10^38 ergs),…
