Current water trapping micro-habitats on the surface of Mars
Anna Bognar, Bernadett D. Pal, Akos Kereszturi
This paper presents a conceptual model exploring how liquid water could be maintained in direct contact with hypothetical microorganisms during warm daytime periods on Mars. Hygros…
Surveying the ice condensation period at southern polar Mars using a CNN
Mira Gergácz, Ákos Kereszturi
Before the seasonal polar ice cap starts to expand towards lower latitudes on Mars, small frost patches may condensate out during the cold night and they may remain on the surface…
Analysing high resolution digital Mars images using machine learning
Mira Gergácz, Ákos Kereszturi
The search for ephemeral liquid water on Mars is an ongoing activity. After the recession of the seasonal polar ice cap on Mars, small water ice patches may be left behind in shady…
Serpentinization in the thermal evolution of icy Kuiper belt objects in the early Solar system
Anikó Farkas-Takács, Csaba Kiss, Sándor Góbi +1
Here we present an improved algorithm to model the serpentinization process in planetesimals in the early Solar system. Although it is hypothesized that serpentinization-like react…
Deliquescence probability maps of Mars and key limiting factors using GCM model calculations
Bernadett D. Pál, Ákos Kereszturi
There may be a chance of small-scale ephemeral liquid water formation on present day Mars, even though the current climate does not support the existence of larger bodies of water.…
Mars: new insights and unresolved questions
Hitesh G. Changela, Elias Chatzitheodoridis, Andre Antunes +33
Mars exploration motivates the search for extraterrestrial life, the development of space technologies, and the design of human missions and habitations. Here we seek new insights…
Mars Astrobiological Cave and Internal habitability Explorer (MACIE): A New Frontiers Mission Concept
Charity M. Phillips-Lander, Ali Agha-Mohammadi, J. J. Wynne +20
Martian subsurface habitability and astrobiology can be evaluated via a lava tube cave, without drilling. MACIE addresses two key goals of the Decadal Survey (2013-2022) and three…
Cold, dry, windy, and UV irradiated -- surveying Mars relevant conditions in Ojos del Salado Volcano (Andes Mountains, Chile)
Á. Kereszturi, J. Aszalós, Zs. Heiling +8
The Special Collection of papers in this issue of Astrobiology provide an overview of the characteristics and potential for future exploration of the Ojos del Salado volcano, locat…
ASIME 2018 White Paper. In-Space Utilisation of Asteroids: Asteroid Composition -- Answers to Questions from the Asteroid Miners
Amara L. Graps, Angel Abbud-Madrid, Paul Abell +41
In keeping with the Luxembourg government's initiative to support the future use of space resources, ASIME 2018 was held in Belval, Luxembourg on April 16-17, 2018. The goal of ASI…
Global seasonal variations of the near-surface relative humidity levels on present-day Mars
B. Pál, Á. Kereszturi, F. Forget +1
We investigate the global seasonal variations of near-surface relative humidity and relevant attributes, like temperature and water vapor volume mixing ratio on Mars using calculat…
CASTAway: An Asteroid Main Belt Tour and Survey
N. E. Bowles, C. Snodgrass, A Gibbings +42
CASTAway is a mission concept to explore our Solar System's main asteroid belt. Asteroids and comets provide a window into the formation and evolution of our Solar System and the c…
Laboratory experiments on the low temperature formation of carbonaceous grains in the ISM
Daniele Fulvio, Sandor Gobi, Cornelia Jaeger +2
The life-cycle of cosmic dust grains is far from being understood and the origin and evolution of interstellar medium (ISM) grains is still under debate. In the ISM, the cosmic dus…
ASIME 2016 White Paper: In-Space Utilisation of Asteroids: "Answers to Questions from the Asteroid Miners"
Amara L. Graps, Philippe Blondel, Grant Bonin +28
The aim of the Asteroid Science Intersections with In-Space Mine Engineering (ASIME) 2016 conference on September 21-22, 2016 in Luxembourg City was to provide an environment for t…
Possibility of microscopic liquid water formation at landing sites on Mars and their observational potential
B. Pál, Á. Kereszturi
Microscopic liquid brines, especially calcium-perchlorate could emerge by deliquescence on Mars during night time hours. Using climate model computations and orbital humidity obser…
Water ice in the dark dune spots of Richardson crater on Mars
A. Kereszturi, M. Vincendon, F. Schmidt
In this study we assess the presence, nature and properties of ices - in particular water ice - that occur within these spots using HIRISE and CRISM observations, as well as the LM…
