{"product_id":"martian-death-rays-von-lewis-dartnell","title":"Martian Death Rays","description":"\u003cp\u003eAny microbial life extant in the top meters of the martian  subsurface is likely to be held dormant for long periods of time by  the current permafrost conditions. In this potential habitable zone, a  major environmental hazard is the ionising radiation field generated  by the flux of exogenous energetic particles: solar energetic protons  and galactic cosmic rays. The research reported here constitutes the  first multidisciplinary approach to assessing the astrobiological  impact of this radiation on Mars. A sophisticated computer model  has been constructed to characterise this complex subsurface  ionising radiation field and explore the influence of variation in  crucial parameters such as atmospheric density, surface  composition, and primary radiation spectra. Microbiological work  has also been conducted to isolate novel cold-tolerant bacterial  strains from the Dry Valleys environment of Antarctica, an analogue  site to the martian surface, and determine their phylogenetic  diversity and survival under high-dose gamma-ray exposure frozen  at -80°C, a temperature characteristic of the martian mid-latitude  permafrost.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838343006\"\u003e\u003ch3\u003eModelling and experimental work on the astrobiological implications of the Mars subsurface ionising radiation environment\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838343006","offer_id":39499105566813,"sku":"9783838343006","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/c8049d72-a12f-46ef-89ba-b916517ad63e.jpg?v=1774935708","url":"https:\/\/shop.autorenwelt.de\/en\/products\/martian-death-rays-von-lewis-dartnell","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
