• Degradation of the organic molecules in the shallow subsurface of Mars due to irradiation by cosmic rays (2012, background): “We found such maximum somewhat artificial for the Martian rocks because Dartnell et al. [2007a, 2007b] did not consider cosmic ray particles with energies below 100 MeV. In our calculations we included primary GCR particles with energies as low as 20 MeV. Low energy cosmic rays (20–100 MeV) cannot p”
• The Sample Analysis at Mars Investigation and Instrument Suite (2012, background): “The latter case may occur either by direct impacts or by secondary reaction with oxidative radicals produced by radiation in the immediate vicinity of the organic molecules (Dartnell et al. 2008).”
• Mars’ Surface Radiation Environment Measured with the Mars Science Laboratory’s Curiosity Rover (2014, unknown): “Several studies have modeled the expected subsurface radiation regime (26, 39), but the dose values depended until now on the modeled radiation environment on the surface.”
• Sustainable life support on Mars – the potential roles of cyanobacteria (2015, background): “Consistently, it has been estimated that even vegetative cells of the bacterium E. coli could survive the ionizing radiation dose that would be received after more than a thousand years on the surface of Mars (Dartnell et al. 2007).”
• Planetary habitability: lessons learned from terrestrial analogues (2014, unknown): “The persistence of life on the Martian surface today seems unlikely, given the extremely cold and desiccating conditions, high UV radiation flux, and the lack of magnetospheric shielding against ionizing radiation (Dartnell et al. 2007).”
